最小壓力閥由閥體、閥芯、調(diào)節(jié)螺母、彈簧、密封元件等組成。
最小壓力閥的作用：
1、最小壓力閥的作用是緩沖一下，當(dāng)機(jī)器在加載瞬間，我們假設(shè)排放到大氣中，機(jī)器內(nèi)部分離前與分離后產(chǎn)生的大壓差將全部加在分離器上，造成對分離器芯的傷害；
2 、機(jī)器油潤滑是靠機(jī)器本身的壓力差進(jìn)行，沒有額外的油泵輔助，當(dāng)機(jī)器在空載狀態(tài)時，仍需一定壓力維持油循環(huán)，所以進(jìn)氣閥門相對關(guān)閉，而最小壓力閥防止壓力泄漏，這樣保證潤滑油循環(huán)。
3、最小壓力閥主要起建立機(jī)組內(nèi)壓，促使?jié)櫥脱h(huán)、滿足減荷閥的工作壓力等作用。
4、另外最小壓力閥也起單向閥的作用，防止機(jī)組在卸載運(yùn)行時儲氣罐中的壓縮空氣倒流至空壓機(jī)。

Minimum pressure valve by valve body, valve core, adjust nut, spring, sealing element, etc.

The role of the minimum pressure valve:

1, the minimum pressure valve is used to buffer, when the machine load moment, we assume that the emissions into the atmosphere, the machine internal separation of before and after the separation of large differential pressure will be added on the separator, the separator core damage;

2, watch oil lubrication depends on the pressure difference between the machine itself, no additional auxiliary pump, when the machine is in idle state, still need some pressure to maintain oil circulation, so the inlet valve is relatively closed, and the minimum pressure valve to prevent leakage, so that guarantee the oil circulation.

Unit 3, minimum pressure valve is mainly to establish internal pressure, pushing oil circulation, satisfy the load reducing valve working pressure, and so on.

4, the minimum pressure valve also ACTS as one-way valve, prevent unloading the runtime propane tanks of compressed air back to the air compressor.
