Side seal pressure的意思|示意

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.

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。

Fluid pressure on one side of the gate presses it against the opposite seat with great force and improves the seal.

闸板压力侧的流体压力使另一侧的阀座受较大的力，提高了密封性。

Too much lip-axis will increase the load-side contacts, while the shaft is too small it will end lip of the seal contact surface pressure enough.

过大的轴会增加唇端的接触载荷，而过小的轴则会使唇端接触面上的密封压力不够。
