High temperature and high pressure power station valve selection depends on the service life of the valve

High temperature and high pressure power station valve selection depends on the service life of the valve of high temperature and high pressure power station stop valve is also called special valve, mainly is suitable for the nominal pressure PN20. 0 - 32. 0 mpa and P ( 54) 100 v - P( 57) 170 v, the working temperature & le; 540℃( The P ( 57) 170 v working temperature is 570 ℃) Oil, chemical industry, hydropower and thermal power plant under various working conditions such as the pipeline, cut off or connect medium. Apply the corrosive medium such as water, steam. The valve compared with other valve products are characterized by high temperature and high pressure, special since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products. High temperature and high pressure power station valve compared with other valve products is characterized by high temperature and high pressure, if only from the aspects of pressure is lower than common valves, purely from the aspects of temperature is lower than than general valve. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products. High temperature and high pressure power station valve has a small shell, light weight, full functions, appearance beautiful wait for a characteristic, and can be used with programmable computer, can also be equipped with electric device according to the requirements of customers. High temperature and high pressure power station valve selection is important to see its service life: 1. The service life of power station valve and its accessories, must be considered during the equipment use through a combination of various environmental conditions. 2. Power station valve repair cycle is consistent, service life of wearing parts with the unit of bidders in the introduction to equipment use indicate that the service life of wearing parts. 3. Power station valve design pressure and design temperature shall not be lower than the design pressure of the pipe connected to and design temperature.
