说明书

The high-temperature and high-pressure main safety valve should be used in conjunction with the impulse safety valve. The type is suitable for the operating temperature ℃. The type is suitable for power station boilers with the working temperature ℃. When the steam pressure in the boiler exceeds the allowable value, the opening pressure signal of the impulse safety valve causes the main safety valve to operate. The safety valve opens and then discharges the entire amount. When the pressure drops to the specified value, the main safety valve automatically closes to ensure safe operation of the equipment. , High temperature and high pressure main safety valve installation instructions
The valve must be installed vertically at the highest position of the equipment.
The main safety valve is fastened to the support, and the support bears the recoil force generated when the main safety valve exhausts steam.
. The exhaust pipe should have a special hanger. The weight of the exhaust pipe should not be added to the main safety valve. The connecting flange between the main safety valve and the exhaust pipe should eliminate any additional prestress.
The lowest point of the exhaust pipe should be considered hydrophobic to avoid water hammer during exhaust.
High temperature and high pressure main safety valves are mainly used in power station boilers, pressure vessels, and temperature and pressure reducing devices to prevent the pressure from exceeding the maximum allowable pressure value and ensure the safe operation of the equipment.
High temperature and high pressure main safety valve When the medium pressure rises to the set pressure, the impulse safety valve opens. The medium enters the piston chamber of the main safety valve from the pulse tube and pushes the piston down, causing the valve to open automatically. When the impulse valve closes , the valve disc automatically closes again. , The sealing surface of the high-temperature and high-pressure main safety valve is made of cobalt-based chromium-nickel stainless steel, and the valve disc has been heat treated to improve wear resistance and erosion resistance.
