螺桿式空壓機進氣閥的工作過程是：啟動、加載、卸載、空調和停機。 

 （1）啟動。電機啟動，主機開始運轉，進氣閥關閉狀態閥芯上的小孔進氣，經過壓縮的油氣進入油氣桶，系統壓力逐漸上升。 

 （2）加載。電機星三角轉換，控制系統會比較系統的實際壓力與設定壓力，當系統壓力低于壓力開關設定下限壓力時，壓力開關動作使加載電磁閥加電，三向電磁閥開啟，向進氣門伺服氣缸供氣推動控制氣缸打開蝶閥，進氣閥全開吸氣；經由電磁閥的壓力同時關閉泄放閥，機器不再放空，罐內壓力持續上升至外向供氣。 

 （3）卸載。當壓力上升到壓差開關上限壓力時，壓差開關發出一個電信號給三向電磁閥，電磁閥關閉停止向進氣門伺服氣缸供氣，控制氣缸不受壓則蝶閥關閉維持小孔進氣，此時受配重控制止回閥能及時迅速的緊密關閉，同時泄放閥打開釋放油氣桶內壓力至基本油壓。空壓機處于空載運行，在加載電磁閥連續失電20min后，系統進入空車過久停車狀態。  

（4）容調。空壓機加載過程中為減少空壓機的空重負荷次數，安裝有反比例閥，當機組壓力達到壓力開關上限前反比例閥提前動作，減少向伺服汽缸的供氣量，進氣閥伺服汽缸閥桿推力減少，在彈簧力的作用下閥桿回縮，當彈簧力與汽缸的氣體推力平衡時，閥桿處于半開狀態，進氣量減少實現空壓機的容量調節。 

 （5）停機。停機信號來自空車過久或系統壓力長時間處于壓力上限，電機停止，主機停轉不再吸氣，進氣閥的內部止回閥迅速關閉確保沒有停機吐油的現象，泄放閥持續放空至外部大氣壓力。

(1) start.The electrical machinery starts, the main engine starts to revolve, on the admission valve off-position valve core eyelet air admission, enters the oil air drum after the compression oil gas, the system pressure rises gradually. (2) load.The electrical machinery star triangle transforms, the control system can the quite systematic actual pressure and the hypothesis pressure, when the system pressure is lower than the pressure switch hypothesis lower limit pressure, the pressure switch movement makes to load the solenoid valve to add the electricity, three to solenoid valve opening, turns on the reed valve to the air intake valve servo air cylinder air feed impetus control air cylinder, the admission valve all opens the inspiration; Simultaneously closes the escape valve by way of the solenoid valve pressure, the machine no longer blows off, pot internal pressure constant rise to extroverted air feed. (3) unloading.When the pressure rises to the differential pressure switch upper limit pressure, the differential pressure switch sends out an electrical signal for three to the solenoid valve, solenoid valve shutting down stops to the air intake valve servo air cylinder air feed, controls the air cylinder not bearing then the reed valve closure maintenance eyelet air admission, this time the counterweight control prevent returning threshold energy prompt rapid close closure, simultaneously the escape valve is opened the release oil air drum internal pressure to the basic flowing tubing head pressure.The air compressor is in the lost motion, after loads the solenoid valve to lose electricity 20min continuously, the system enters the spatial vehicle to stay for a long time the vehicle condition. (4) Rong Diao.The air compressor loads in the process for to reduce the air compressor the bare weight load number of times, the installment has the inverse proportion valve, when the unit pressure achieved in front of the pressure switch upper limit the inverse proportion valve acts ahead of time, reduces supplies the spirit to the servo cylinder, the admission valve servo cylinder valve lever thrust force to reduce, in under spring strength function valve lever retraction, when spring strength and cylinder gas thrust force balance, the valve lever is at the ajar condition, the air input reduction realizes the air compressor volume control.
