Hardware Knowledge Hall: spring-type safety valve working principle
Spring-loaded safety valve relies on the force of the spring to press the valve core against the valve seat so that the safety valve is in the closed state. The force of the valve is forced upward by the steam. Normal operation, the spring pressure is greater than the downward pressure of steam upward thrust, the valve is closed. When the steam pressure reaches the safety valve seat pressure, the steam on the spool force greater than the spring force, so that the top of the valve spool, rotor pump safety valve exhaust. Through the stem of the upper part of the adjustment screw to change the tightness of the spring, you can adjust the pressure relief valve seat. This safety valve has the advantages of convenient adjustment, small volume and weight, large exhaust capacity, and the like, and is applicable to boilers with different parameters and different capacities.
