Description
Technical field
The utility model relates to valve part field, specifically a kind of valve opening and closing positioning device.
Background technique
Valve is for being opened and closed pipeline, control flow direction, the parameter (temperature, pressure and flow) of regulation and control pumped (conveying) medium
Pipeline fittings.According to its function, shut-off valve, check-valves, regulating valve etc. can be divided into.Valve is the control in fluid delivery system
Component has the function of cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting or overflow pressure relief etc..For fluid control systems
Valve, various valves, kind and specification used in from simplest shut-off valve to extremely complex robot control system(RCS) are quite numerous
It is more.Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium etc.
The flowing of various types fluid.Valve is also divided into cast iron valve, cast steel valve, stainless valve (201,304,316 according to material
Deng), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
