Thicker knife gate to eliminate distortion under maximum differential pressure and to provide tight seating ( see page 12 ) 更厚的刀闸能够避免在最大压差环境下产生的扭曲，保证阀座的气密性密封（参阅第12页） 。

The most common method of determining maximum differential pressure across the valve seats is to assign the maximum design or operating pressure the upstream value p1 and assume a downstream pressure p2 of 0 psig 测定阀门阀座的最大压差的最常用方法是将最大设计或工作压力作为上游的压力值p1 ，然后假定下游压力值p2为0psig
