Nov 23, 2017

Pilot safety valve according to the structure of the form, divided into vertical hammer type, lever type, spring type and pilot type (pulse type); according to the structure of the valve can be divided into closed and non closed type of two. Closed safety valves, which are excluded from the leak, are all discharged along the outlet to the designated site, generally used in toxic and corrosive media. For air and steam safety valve, the use of non closed safety valve. For the selection of safety valve products, the actual sealing pressure should be determined. For spring type safety valve, in a nominal pressure (PN) range, with several working pressure level of the spring, in order to specify the safety valve type, name, medium and temperature, should also specify the valve sealing pressure, otherwise the maximum sealing pressure supply.

Safety valve is an automatic valve, mainly used in boilers, pressure vessels and pipes, the control pressure does not exceed the prescribed value, and plays an important role in the protection of personal safety and equipment operation. According to the opening height of the safety valve clack, it can be divided into micro opening type safety

Pilot operated safety valve

Safety valve and safety valve, micro valve opening stroke: height is less than or equal to 0.05d0 (minimum discharge throat diameter); safety valve opening height is less than or equal to 0.25d0 (minimum discharge throat diameter).
