Description
Technical field
The utility model relates to a kind of technical field of hydraulic equipment, particularly relates to a kind of valve.
Background technique
For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve (201,304,316 etc.), molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized material such as valve such as grade.Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be the medium in pipe arrangement and equipment (liquid, gas, powder) is flowed or stops and the device of its flow can be controlled.Valve is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.For the valve that fluid controls, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification various, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.Can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid fluidly to flow, the working pressure of valve can ultrahigh pressure from 0.0013MPa to 1000MPa, and operating temperature is from the ultralow temperature of-270 DEG C to the high temperature of 1430 DEG C.
The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electricity surges, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, or do not rely on transducing signal and simply open or close, valve rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.
Can be divided into by effect and purposes: (1) blocks class: as gate valve, stop valve, stopcock, ball valve, butterfly valve, needle type valve, membrane valve etc.Block class valve also known as cut-off valve, stop valve, its effect is the medium connected or block in pipeline.Safety check, safety check is also known as one-way valve or check valve, and safety check belongs to a kind of automatic valve, and its effect prevents the medium in pipeline from flowing backwards, prevents pump and drive motor from reversing, and the leakage of vessel media.The bottom valve that pump sump closes also belongs to safety check class.Explosion-proof valve, guard valve etc., the effect of safety valve prevents the pressure medium in pipeline or device from exceeding specified value, thus reach the object of safety protection.Modulating valve, throttle valve and reduction valve, its effect is the parameter such as pressure, flow regulating medium.(2) vacuum types: as Vacuum ball valve, vacuum flapper valve, vacuum gas filling valve, Pneumatic vacuum valve etc.Its effect is in vacuum system, is used for changing airflow direction, regulates throughput size, and the vacuum system element cutting off or connect pipeline is called vacuum valve.(3) specific use class: as pipe cleaning valve, atmospheric valve, blowdown valve, outlet valve, filter etc.Outlet valve is requisite auxiliary element in pipe-line system, is widely used in boiler, air-conditioning, petroleum gas, water supply and sewerage pipeline.Often be arranged on the place such as commanding height or elbow, excessive gas, raising pipeline road utilization efficiency and reduction energy consumption in purging line.By nominal pressure (1) vacuum valve: refer to the valve of working pressure lower than standard atmospheric pressure.(2) low pressure valve: the valve referring to nominal pressure PN≤1.6Mpa.(3) middle pressure valve: refer to that nominal pressure PN is the valve of 2.5Mpa, 4.0Mpa, 6.4Mpa.(4) high pressure valve: refer to that nominal pressure PN is the valve of 10.0Mpa ~ 80.0Mpa.(5) excess high pressure valves: the valve referring to nominal pressure PN >=100.0Mpa.(6) filter: refer to that nominal pressure PN is 1.0Mpa, 1.6Mpa.Can be divided into by operating temperature: (1) ultra-low temperature valves: for the valve of media operation temperature t<-101 DEG C.(2) normal temperature valve: for the valve of media operation temperature-29 DEG C of <t<120 DEG C.(3) warm valve in: for the valve of media operation temperature 120 DEG C <t<425 DEG C.(4) high-temperature valve: for the valve of media operation temperature t>425 DEG C.
Current existing valve in use easily produces larger noise, and in the environment of High Temperature High Pressure, long-time use can produce leakage.
