定时受提升阀重量，弹簧振频，提升阀阀程，活塞速度以及活塞直径的影响。

This timing is affected by the relationship among poppet weight, spring rate, poppet travel distance, plunger speed, and plunger diameter.

升降式止回阀使用一个可承受弹簧载荷的轻量阀瓣，阀瓣的升程不高。

Lift check valve with a spring load can withstand light valve flap, flap valve lift is not high.
