What are the requirements for the working performance of the boiler safety valve?

(1) When the boiler reaches the maximum allowable pressure, the safety valve should be able to reliably open to the full opening height and discharge the specified amount of steam in time.

(2) When the safety valve is open, it should work smoothly and should not oscillate discharge.

(3) The safety valve can return to its seat and close in time when the boiler pressure drops slightly below the working pressure, and ensure tightness.

(4) The safety valve has better self-sealing in the closed state.
