Seal face geometry parameters can be optimized by analyzing regulation of their effect on opening force and liquid film stiffness.

通过分析端面结构参数对密封开启力和液膜刚度的影响规律，可得到端面结构的优化参数。

If a required seal can be achieved without exceeding 45 foot-pounds of force, the connection can be used.

如果用不超过45英尺-磅的力能够达到要求的密封，这种接头就可以使用。

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。
