Operation principle of pressure relief measurement
1. Released from the lubricating pump, the lubricant drives the umbrella-shaped valve upward;  
2.当伞形阀把芯杆中心孔封住后,压动活塞克服弹簧力开始上升,将上腔原先贮存的油剂往外排出;
3.当活塞移至上腔顶点时,排油也同时完毕;
4.润滑泵停止供油时,其卸压阀自行开启,使主油管内压力油通过卸压阀回油,此时系统压力下降,计量件中的活塞在弹簧作用下开始回复,当伞形阀回复封住计量件进油口,则活塞把贮存在下腔的油剂通过芯杆小孔压送到上腔,同时下次的供油也准备完毕。
