Description
Technical field
The utility model relates to technical field of valve manufacturing, specifically, being a kind of tune as super large caliber regulating valve
Pole structure.
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..
Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radioactivity
The flowing of the various types fluid such as medium.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve (201,
304,316 etc.), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
Regulating valve also known as control valve, in industrial automation process control field, by receiving regulation unit output
Control signal, the final control element for changing rate-of flow, pressure, temperature, the technological parameters such as liquid level is removed by power operation.
Generally it is made of executing agency and valve.If pressing stroke feature, regulating valve can be divided into Direct Travel and angle stroke；Match by it and holds
The power that row mechanism uses can be divided into pneumatic control valve, electric control valve, three kinds of hydraulic adjusting valve；By its function and characteristic
It is divided into linear characteristic, equal percentage characteristics and three kinds of parabolic characteristic.Regulating valve is suitable for empty gas and water, steam, various corrosivity
The media such as medium, mud, oil product.English name: control valve, position number usually FV beginning.Regulating valve common classification: pneumatic
Regulating valve, electric control valve, hydraulic adjusting valve, direct-operated regulator, but existing regulating valve is there is significant limitation,
It is unable to satisfy the needs of modernization industry production.
Current major city heat supply engineering long-distance transport pipes super large caliber all-welded ball valve demand increasingly increases, due to state
The limitation of interior technology and manufacture level, required valve are at based on import, increase project cost.
Utility model content
The purpose of this utility model is just to provide a kind of adjusting rod structure as super large caliber regulating valve, can be used in super
