What are Spring Loaded Safety Valves
Spring loaded safety valve refers to locking the valve or plunger and other seals of the valve by relying on the elastic pressure of the spring. Once the pressure of the pressure vessel is abnormal, the high pressure generated will overcome the spring pressure of the safety valve, so the locking device is pushed open to form a pressure relief channel to release the high pressure. According to the different opening height of the valve disc, it is divided into full lift type and micro lift type. The full lift type has large discharge capacity and good resilience. It is suitable for liquid and gas media, and the micro lift type is only suitable for liquid media.
