As thermal expansion conditions develop, pressure builds up to the setting of the reliefvalve. This will cause discharging of small quantity of water.
随着热量的增加，压力也随着增加，并达到安全阀的压力设置。此时将导致安全阀排泄出少量的水。
2
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.
安全泄压阀用于通过泄漏阀或热膨胀防止容器的管子系统超压。

A pressure reliefvalve must be installed as shown to prevent excess pressure by thermal expansion.
