In our current valve on the market, with the exception of low-pressure valve on the international market to achieve an acceptable level, high-pressure valves still need to rely on imports. In the continued good macro-economic situation, most of the valve industry production and sales targets have increased rapidly, but the impact of a price war, industry sales and profits fell sharply from a year earlier. With the world economy pick up, China’s import and export of valve products also increased, but because of the high-end technology compared with foreign manufacturers are still a wide gap between the period of time in the future, technology will become the constraints of our valve products The development of a bottleneck.Water Control Valve 100D water-level valve 100X remote control float valve 200X pressure reducing valve 800X Pressure Difference Balance Valve 900X Emergency Shut-off Valve 400X Flow control valve 500X pressure relief or sustaining valve 600X electrical control valve 700X Pump Control Valve

　　Valve oil, chemicals, power, long-distance pipelines, shipbuilding, nuclear industry, a variety of low temperature engineering, aerospace and marine sectors of the national economy such as oil indispensable fluid control equipment. After years of development, China’s valve business volume in the first home of the world, a variety of large and small enterprises VALVE more than 6,000, of whom more than 5,000,000 yuan in output value of 900. Products from the point of view, China’s valve industry is now capable of producing more than 10 product categories, such as valve, the cut-off valve, ball valve, butterfly valve, safety valve, check valve, throttle, Xuan Sefa, the relief valve , Valves, trap, emergency shut-off valve, and so on, the use of the maximum temperature reached 570 ℃, a minimum of -196 ℃, the highest pressure 600MPa, the largest path to reach 5350 mm. In addition, in accordance with relevant statistics, China’s annual market turnover valves up to 500 billion yuan, of which more than 100 billion market by foreign enterprises valve occupation.

　　At present, China’s valve industry are still some problems still exist, such as China’s main valve business to low-level, small-scale, family-style workshop enterprises. In products, because of duplication of investment, lack of technology, our valve business is still the leading products of low quality and popular products. China’s production of a variety of the prevalence of valve leakage, with leakage, the appearance of high-quality, short life expectancy, as well as the flexibility to operate non-electric valves and pneumatic devices are not reliable, and other shortcomings of the device, part of the product is equivalent to only 80 of the last century In the early international level, a number of key installations and high temperature and high pressure valve on the need to continue to rely on imports. In addition, China’s industrial structure in the valve industry, the industrial valve industry chain, industry, as well as the degree of specialization with foreign enterprises there is a big gap. Valve caused by domestic product quality due to low: the market due to the rapid expansion of the existing state-owned enterprises have Guantingbingzhuan valve, although the number of township enterprises developed rapidly, but due to the low starting point for village and township enterprises, technical strength is very weak, poorly equipped , The majority of products are imitating the production, in particular, water supply and drainage valves used in low-voltage problem. But these problems do not affect the future of China’s valve industry prospects. This is mainly due to the support of national policies and valve products, strong market demand, in particular, a number of projects of the century, “West-East Gas Pipeline” and “east” and “South-North Water Diversion” and other projects need to start a large number of The valve product support. In addition, China is faced with the arrival of the industrial age, the petrochemical industry, power industry, metallurgical industry, chemical industry and urban construction, such as the use of large valves will increase demand for valves. For example, the electric power industry, “11th Five-Year Plan” period coal-fired electricity generating units in large and medium-sized projects for a total of the necessary valves forecast: valve of the total demand for 153,000 tons with an average annual demand of 30,600 tons; valve of the total amount of demand for 39.6 Billion, with an average annual demand amounted to 792,000,000 yuan. In addition, China is becoming the world’s biggest processing plant, the production of valve products face an even greater room for development. So as long as companies can seize the opportunity to strengthen R & D capability and constantly increase the scientific and technological content of products and product quality, will be able to fierce market competition to occupy the status of the initiative.

Valve is used to control fluid flow, pressure and flow to the device. Controlled fluid can be liquid, gas, gas-liquid mixture or a mixture of solid-liquid. Usually by the valve body, valve cover, valve seats, pieces of gate, drive mechanism, seals and fasteners, and other components. The valve control is to rely on drivers or fluid movements driven hoist pieces, slip, or spin before turning motion to change the flow to an area the size of the achievable.

牋牋� The valve uses a wide, with people’s daily lives are closely related, such as effective water taps, kitchen used liquefied petroleum gas pressure reducing valves are. Valve is also a variety of mechanical equipment, such as internal combustion engines, steam engines, compressors, pumps, air pressure transmission, hydraulic transmission vehicles, vessels, such as an indispensable component. BC two years ago, the Chinese people in the aqueduct on the use of bamboo and Muse valve later in the use of irrigation sluice, used in smelting bellows on the use of a non-return valve plate, Well Salt mining in the use of bamboo And possession of a non-return valve plate with the extraction of salt water and hydraulic machinery smelting technology development in Europe and the emergence of copper Qian Zhi Xuan Sefa. With the use of the boiler, in 1681 there was a heavy hammer lever-type safety valve. 1769 Watt steam engine appeared before a non-return valve and Xuan Sefa has been the main valve. The invention of the steam engine so that the valve has entered the field of machine-building industry. In addition to Watt’s steam engine on the use of Xuan Sefa, a safety valve and check valve, butterfly valve used to regulate traffic. With the steam flow and pressure of the increased use of Xuan Sefa control of the steam engine and steam into the exhaust can no longer satisfy the need, so there have been sliding valve. Before and after 1840, have emerged one after another with the cut-off valve stem thread, and with trapezoidal screw valve stem of the wedge, which is a valve in the development of a major breakthrough. The emergence of these two types of valves, not only to meet a variety of industries at the time of pressure, temperature rising demands and to meet the initial flow of regulation. Since then, with the power industry, petroleum industry, chemical industry and shipbuilding industries, a variety of high and medium pressure valve has been developing rapidly.

牋牋� After the Second World War, as the polymer materials, lubricating materials, stainless steel and Co-based Cemented the development of age-old Xuan Sefa butterfly and access to new applications, Ball Valves, and rapid development. Cut-off valves, Gate Valve and other varieties, improve the quality. Mechanical valve manufacturing has gradually become an important industrial sector. Valve-per-use features can be divided into the gate valves, valve, check valve, the shunt valve, safety valve, the use of six types of valves. Cut off the main valve for fluid cut off access roads, including the cut-off valves, valve, Xuan Sefa, Ball, Butterfly Valves, folder, such as control valves; the main control valve for regulating the pressure of the fluid, such as traffic, including control valve, section Flow valve, relief valve and the float valve, and so on; for a non-return valve to prevent reverse flow of fluid; shunt valve for the distribution channel where the fluid, or two-phase separation, including slide valves, valve, hydrophobic Valves and emptying valves and so on; the main safety valve for the protection of security to prevent the boilers, pressure vessels or as a result of over-pressure pipeline and the damage; use more than one type of valve is a function of the valves, such as the cut-off valve can flow from While the role of start-stop back to the role. Industrial pipeline valves by nominal pressure valve can be divided into a vacuum, low-pressure valves, pressure valves, high-pressure valve, high pressure valve; valve according to the temperature at room temperature can be divided into valves, valve temperature, high temperature valve, low-temperature valve; valve Doors can also be driven by the type of device type, and the pipeline linking the body and the way the use of classified materials. Pressure Seal Gate Valve ANSI 125 Non-Rising Stem Cast Iron Gate Valve ANSI 125 Rising Stem Cast Iron Gate Valve DIN3352 F5 Non-Rising Stem Cast Iron Gate Valve DIN 3352 F5 Rising Stem Cast Iron Gate Valve Bellows Gate Valve Gate Valve 800Lb

牋牋 Valve can be a variety of classification alone or in combination names can hoist pieces of the structure or use of specific names. Valve is the basic parameters of pressure, temperature and diameter. For use in a variety of industrial pipeline valves, and the nominal pressure common nominal path as the basic parameters. Refers to a nominal pressure valve material, the set temperature, the maximum allowed under the pressure of work. Nominal Path refers to the body and tubes connected to the end of the diameter of the name. According to the valve types and their uses have different requirements, are sealed, strength, conditioning, circulation, such as gate performance. In the design and selection of valves, in addition to considering the basic parameters and performance, they also have to consider the performance of fluid, including the fluid phase (gas, liquid or solid particles containing), corrosive, viscosity, toxic, flammable easy Explosion, precious and rare radioactive, and so on. Seal strength and performance properties of all the valves is the most fundamental and important performance. The valve seal and seal their duties outside the sealing of two parts. Flap valve is sealed with the seal between the valve seat; outside the stem is sealed with the parts of movement between the valve cover, valve cover and body and between the valve and pipeline link between the parts of the seal. When used in the valve requires not only good sealing performance, and security must be guaranteed. If not sealed and the leak occurred or not enough strength as a result of damage to parts which will result in varying degrees of economic losses, such as the transportation of toxic, flammable or corrosive fluid strong, but also could lead to serious accidents. In order to ensure the valve seal strength and, in addition to comply with reasonable standards for structural design, to ensure that the quality of the process, it is also necessary to choose the right materials. In general, non-corrosive fluid with low-pressure valve of the use of cast iron or bronze; high pressure valves used in steel or steel; the use of high-temperature alloy steel or high-pressure valve; for the corrosive fluid valve with stainless steel, plastics, Corrosion resistance alloys (such as molybdenum copper-nickel alloys, titanium and lead alloys, etc.) or cast iron, cast steel corrosion lining materials. Typically, low-pressure valve sealing surface of most of the use of brass or bronze, high pressure valves are mostly used in stainless steel, the higher the high, medium or high temperature valve pressure valve, such as the use of Co-based Cemented. Polymeric materials in the valve has been widely used, such as the ball valve seat mainly PTFE plastics, Butterfly Valves and sealing the divide of the various rubber materials. These materials can be used in the temperature range with a better seal than metal. With modern nuclear industry, petrochemical industry, electronic industry and the development of the aerospace industry, as well as process automation technology and the development of long-distance transmission fluid, and promote modern cryogenic valves, vacuum valves, valve used in the nuclear industry and regulating valve发展. For the remote control and the control valve drive more and more applications.

牋牋� Valves in the future development of products that will expand the parameters of the development of energy-saving, labor-saving and automatic control valves, to improve the structure of the new materials and new technology to improve the life of valves, as well as the development of special valves, and other family Famian development, such as In the liquid oxygen and liquid hydrogen and liquefied natural gas, such as the low-temperature valve, vacuum valves, nuclear industrial valves, safety valves, valve, valve and trap drives, and so on.

　　Chinese industries commonly used metal valves for valves, metal valves have been used on 100 years of history, although the metal structure of the valve through the material and improve, but the metal material property restrictions, can not meet the rising Wear and tear, corrosion, such as strong demand for harsh operating conditions, mainly in the short life, serious leaks have greatly affected the stability of the system. Traditional metal valves from the much-needed materials, design and manufacturing process for radical reforms in areas such as. Ceramic materials will be used in the valve industry is a bold and useful innovation. Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, under normal circumstances, the composition of the ceramics of small radius of the ion crystal and plasma high-price, large coordination number, which determines the nature of the ceramic material tensile Strength, compressive strength, elastic modulus, hardness and so on, very high. However, the ceramic itself, “brittle” and difficult process limits the scope of its application in the past decade, due to the martensitic transformation toughening technology, composite materials and nano-ceramic technology Section of the concept of development and progress, has ceramic ” Fragile “greatly been improved, the toughness and strength has been greatly improved, expanding the scope of application.Plug Valve Plug Valves With Single Or Double Flush Inverted Pressure Balance Lubricated Plug Valve Sleeve Type Soft Sealing Plug Valve 3-Way,4-Way Plug Valve Connection Lift Plug Valve Orbit Plug Valve Flange-Connection Lifting Plug Valve

　　In recent years, a new type of ceramic material in the petroleum, chemical, machinery and so on are very active in the field of application, the use of ceramic wear, decay and the production of wear resistant metal parts instead of the Department of materials, high-tech materials in recent years is an important market One of the development. Ceramic valves of the socio-economic benefits: 1. Ceramic valves using a new type of high-tech ceramic material structure of the valve seal parts and components of vulnerability, increased valve wear products, anti-corrosion and sealing, greatly extended the valve The life of the door. 2. The use of ceramic valves can be greatly reduced the number of the replacement valve repair and improve equipment operation system security, stability, saving the cost of repair equipment. 3. Ceramic valves can be used to improve the sealing of industrial piping systems, to reduce the maximum disclosure so as to protect the environment. 4. Ceramic manufacturing a wide range of raw materials, low-cost, aluminum, carbon, silicon, and other non-general will be able to create superior performance ceramic materials, can save a large number of rare metal materials and mineral resources. Wear-resistant ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, waste water treatment industry, particularly in the face of high wear and tear, corrosion strong, high-temperature, high pressure, such as poor working conditions, ceramic valves have indicated that it is excellent Performance. Ceramic valves to meet the high wear and tear, corrosion strong use of the environment, in particular, is a prominent feature of the long service life, cost of the ceramic valves are far superior to other similar metal valve. With the continuous development of science and technology and progress, ceramics from the formula, forming, machining and assembly processes and other technology more mature and complete, ceramic valves for its outstanding performance has been a growing recognition of the valve industry . Manufacturers use the successful experience of ceramic valves can also be used to promote a wider field of engineering.

　　Valve life abroad, said there are two methods: the use of a number of years, a number that is a switch. Nuclear industrial valve service life is that the general life expectancy is 30 to 40 years, the United States, Germany nuclear power to ensure that the valve used for 40 years, the United Kingdom for 30 years, Japan 30 to 40 years.

　　Switch to the number that must be the highest number of switches in the United Kingdom Ouxi Er (0 rsea 1) Valve Corporation. DNl, 4 ~ 2 inch, PNl000-pound class plunger at room temperature, the number of switches as many as 1 2 5 million, the United States patent WKM companies DYNA-ball 310, switch lO million without leakage. Japan’s Wada valve bellows valve switch production of 100 million, the United States GK’s membrane switch production of up to 130,000 times, the United States 6 inches of cast iron gate valve switch 30,000 times. As the conditions for the use of the differences in test methods are different, not necessarily that the number of switching valve life. Only the same working conditions, use or test the same method, the number of multi-switch or use a long time to be considered a long life.

check valve: also known as a one-way valve or Check Valves. Pipeline used to prevent reflux of a fluid valve. So pipeline fluid can only make one-way flow of fluid when the clock back, the flap valve can be shut down automatically to prevent backflow. According structure can be divided into two categories : elevating and spin-Kai (or a shake-flap). Former perpendicular to the valve flap valve passageway movements with valve are generally designed as a cut-off valve and valve common. The latter is a flap valve around the sealing surface for rotating movement, resistance than elevating small, poor sealing performance.

Plug valves, are valves with cylindrical or conically-tapered “plugs” which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open. Plug valves are simple and often economical.

When the plug is conically-tapered, the stem/handle is typically attached to the larger diameter end of the plug. Plug valves usually do not have bonnets but often have the end of the plug with the handle exposed or mostly exposed to the outside. In cases like that, there is usually not much of a stem. The stem and handle often come in one piece, often a simple, approximately L-shaped handle attached to the end of the plug. The other end of the plug is often exposed to the outside of the valve too, but with a mechanism which retains the plug in the body.

The simplest and most common general type of plug valve is a 2-port valve, which has two positions, open to allow flow, and shut (closed) to stop flow. Ports are openings in the valve body through which fluid can enter or leave. The plug in this kind of valve has one passageway going through it. The ports are typically at opposite ends of the body; therefore, the plug is rotated a fourth of a full turn to change from open to shut positions. This makes this kind of plug valve a quarter-turn valve. There is often a mechanism limiting motion of the handle to a quarter turn, but not in glass stopcocks.

Slightly conically-tapered metal (often brass) plug valves are often used as simple shut-off valves in household natural gas lines.

It is also possible for a plug valve to have more than two ports. In a 3-way plug valve, flow from one port could be directed to either the second or third port. A 3-way plug valve could also be designed to shift flow between ports 1 and 2, 2 and 3, or 1 and 3, and possibly even connect all three ports together. The flow-directing possibilities in multi-port plug valves are similar to the possibilities in corresponding multi-port ball valves or corresponding multi-port valves with a rotor. An additional possibility in plug valves is the have one port on one side of the plug valve and two ports on the other side, with two diagonal and parallel fluid pathways inside the plug. In this case the plug can be rotated 180隆� to connect the port on the one side to either of the two ports on the other side.

Stopcocks used in laboratory glassware are typically forms of conically-tapered plug valves. When fused with the glassware, the valve bodies are made of glass. Otherwise, they can be made of an inert plastic such as Teflon. The plugs can be made of a similar plastic or glass. When the plug is made of glass, the handle and plug are fused together in one piece out of glass. When glass is used for both the stopcock body and the plug, the contacting surfaces between them are special ground glass surfaces (see Laboratory glassware) often with stopcock grease in between. Special glass stopcocks are made for vacuum applications, such as in use with vacuum manifolds. Stopcock grease is always used in high vacuum applications to make the stopcock air-tight.
