We suggest the use of a model DET expansion tank, the Watts Governor 80 ball cock with integral thermal expansionreliefvalve, or a 530C calibrated pressure relief valve.
Therefore each line or line section shall have an expansion chamber a pressure reliefvalve or rupture disc discharging to a receiver.
各管路或管段应配备膨胀室,减压阀或将压力释放到储气罐的爆破隔膜。

The purpose of the safety reliefvalve is to prevent over-pressuring of pipe systems of vessels either through leaking valves or due to thermal expansion.
