Safety valve: Spring type safety valve key with the mutual force of spring work, spring type safety valve and closed and not closed two kinds of structure, generally flammable, flammable and explosive or harmful substances should be used closed, vapor or rare gas can be used not closed, in the spring type safety valve also has a wrench and no wrench, The function of the wrench is mainly to check the convenience level of the piston valve, and sometimes it can be used as a manual emergency pressure relief.

Spring safety valve with heat pipe radiator is used when the temperature is high. Pressure regulating valve: It is an automatic gate valve based on changing the total area of throttle valve, so that the mechanical energy of water flow and liquid change, resulting in different pressure damage, so as to achieve the goal of pressure relief, and with the help of its own kinetic energy control and adjustment system software adjustment, the round line compression spring makes the pressure after the valve fluctuation and spring force phase, so that the pressure after the valve in a certain deviation range to maintain stability.
