How many degrees of high temperature can high pressure flat gate valve withstand
The high pressure flat gate valve adopts a new balanced floating sealing structure, which is suitable for oil and natural gas pipelines with pressure less than 40MPa and temperature not higher than 120 ℃. It is used as the opening and closing and regulating device of control medium. The product has novel structure design, proper material selection, strict test and easy operation.
The high pressure flat gate valve has reasonable structure, reliable sealing and easy operation. All sealing surfaces are spray welded with cemented carbide. It has the advantages of corrosion resistance, wear resistance and corrosion resistance, and can be used for throttling. It is suitable for water, oil, mud and natural gas pipelines with working pressure ≤ 42ma and working temperature ≤ 120 ℃ as the opening and closing and regulating device for controlling medium flow.
High pressure flat gate valve is mainly used in power plant boilers, pressure vessels and temperature and pressure reducing devices to prevent the pressure from exceeding the allowable high pressure value and ensure the safe operation of the equipment. When the medium pressure rises to the set pressure, the impact safety valve opens, and the medium enters the piston chamber of the main safety valve from the pulse pipe, and pushes the piston downward to open the valve automatically. When the impact valve is closed, the valve disc automatically closes again. The sealing surface is made of cobalt base chromium nickel stainless steel. The disc is heat treated to improve wear resistance and erosion resistance.
