1, the steam boiler safety valve, generally used in open entire Kai spring safety valve;
2, the liquid medium with a Pilot Safety Valves, generally used Weiqi safety valve spring;
3, air or other gas medium with a safety valve, generally used in the entire Kai spring safety valve closed;
4, LPG tankers or liquefied petroleum gas tanker railroad safety valve, generally used all Kai built safety valve;
5, production wells outlet safety valve, generally used in the pilot valves;
6, high-pressure bypass valve steam generating equipment, generally used in a safe and controlled dual function of the pilot valve
7, if the requirements of the safety valve for regular open test should be used to enhance the wrench with a safety valve. When the pressure reaches more than 75% of the opening pressure of the medium can be used to enhance the wrench slightly lifted from the valve seat to open the check valve flexibility;
8, if the medium temperature is higher, in order to reduce the temperature of the spring chamber, usually enclosed safety valve when the temperature exceeds 300 ℃ and open safety valve when the temperature exceeds 350 ℃, should be used with a radiator valve;
9, if the back-pressure valve outlet is changing, the change amount exceeds the opening pressure of 10%, should be used bellows safety valve;
10, if the medium is corrosive and should be used bellows safety valve, to prevent important part due to media corrosion and failure.
11, the safety valve installation and maintenance should note the following construction, installation points
12, the safety valve at the outlet should be no resistance, to avoid compression phenomenon.
13, the safety valve should be specifically tested before installation and check its official seal.
14, on the use of the safety valve should be checked regularly
