When the equipment or pipeline pressure or temperature exceeds a set gas stove safety valve, pressure relief or cooling automatically open to ensure that equipment and the pipeline medium pressure (temperature) is below the set pressure (temperature), protective equipment and piping work, prevent accidents and reduce losses. The main valve is widely used in: steam boilers, LPG tankers or liquefied petroleum gas rail tankers, oil wells, high pressure bypass steam generating equipment, pressure piping, pressure vessels. Valve general form of the structure is divided into spring safety valve and lever safety valve, pulse valve, where the most common spring safety valve; press connection into threaded flange valve and safety valve.
