Stainless steel pump safety valve which are the technical requirements
Stainless steel pump safety valve which one of the technical requirements, the setting pressure is greater than 3.0Mpa steam safety valve or the medium temperature is greater than 235 ℃ air or other gas safety valve, should be able to prevent the discharge of media directly erosion spring. Second, the stainless steel pump steam safety valve must be equipped with a wrench, when the medium pressure reaches the set pressure of 75% or more, can use the wrench to lift the valve, the wrench on the valve should not cause obstacles. Third, in order to prevent the adjustment of the amount of spring compression mechanism loose, as well as the freedom to change the pressure has been adjusted, must be equipped with anti-loose device and seal. Fourth, for toxic or flammable media safety valve must be closed safety valve, and to prevent the valve cover and cover gasket leaks. Fifth, the stainless steel valve seat should be fixed on the valve body, not loose, Park Taibang all-in-one safety valve should be provided with a mechanism to limit the opening height. Six, stainless steel pump safety valve even if some damage, any should be able to reach the rated displacement, when the spring is damaged, the valve and other parts will not fly out of the valve body. Seven, with additional back pressure of the safety valve, should be based on the size of the pressure and changes in the situation, set back pressure balance mechanism. Eight, stainless steel pump pilot-operated safety valve should be pilot and main valve for sealing and opening action test should meet the performance standards required.
