在疏水阀两侧应该安装连接装置和关断阀，以简化维修和疏水阀测试。

Union fittings and shutoff valves should be installed on both sides of trap for ease of servicing and trap testing.

而压力侧以相同的力削弱了密封，这样使阀盖腔室和阀杆填料几乎总是承受最大管道压力。

The same force tends to reduce the seal on the pressure side with the result that bonnet cavity and the valve stem packing are nearly always subjected to maximum pipeline pressure.
