螺杆式空压机进气阀的工作过程是：启动、加载、卸载、空调和停机。 

 （1）启动。电机启动，主机开始运转，进气阀关闭状态阀芯上的小孔进气，经过压缩的油气进入油气桶，系统压力逐渐上升。 

 （2）加载。电机星三角转换，控制系统会比较系统的实际压力与设定压力，当系统压力低于压力开关设定下限压力时，压力开关动作使加载电磁阀加电，三向电磁阀开启，向进气门伺服气缸供气推动控制气缸打开蝶阀，进气阀全开吸气；经由电磁阀的压力同时关闭泄放阀，机器不再放空，罐内压力持续上升至外向供气。 

 （3）卸载。当压力上升到压差开关上限压力时，压差开关发出一个电信号给三向电磁阀，电磁阀关闭停止向进气门伺服气缸供气，控制气缸不受压则蝶阀关闭维持小孔进气，此时受配重控制止回阀能及时迅速的紧密关闭，同时泄放阀打开释放油气桶内压力至基本油压。空压机处于空载运行，在加载电磁阀连续失电20min后，系统进入空车过久停车状态。  

（4）容调。空压机加载过程中为减少空压机的空重负荷次数，安装有反比例阀，当机组压力达到压力开关上限前反比例阀提前动作，减少向伺服汽缸的供气量，进气阀伺服汽缸阀杆推力减少，在弹簧力的作用下阀杆回缩，当弹簧力与汽缸的气体推力平衡时，阀杆处于半开状态，进气量减少实现空压机的容量调节。 

 （5）停机。停机信号来自空车过久或系统压力长时间处于压力上限，电机停止，主机停转不再吸气，进气阀的内部止回阀迅速关闭确保没有停机吐油的现象，泄放阀持续放空至外部大气压力。

Screw-type air compressor intake valves work the process is: starting, loading, unloading, air conditioning, and downtime.
(1) start. Motor starts, the host began running, into the holes of the valve closed valve inlet, compressed gas into oil barrels, system pressure is rising gradually.
(2) load. Motor star triangle conversion, control system will compared system of actual pressure and set pressure, dang system pressure below pressure switch set lower pressure Shi, pressure switch action makes loaded electromagnetic valve added electric, three to electromagnetic valve opened, to intake door servo cylinder gas promoted control cylinder open butterfly valve, into valve full inhale; through electromagnetic valve of pressure while close relief put valve, machine no longer vent, tank within pressure continued rose to outgoing gas.
(3) unloaded. Dang pressure rose to pressure poor switch ceiling pressure Shi, pressure poor switch issued a signals to three to electromagnetic valve, electromagnetic valve close stop to intake door servo cylinder gas, control cylinder not by pressure is butterfly valve close maintained small hole into gas, at by distribution heavy control check back valve can timely quickly of close close, while relief put valve open release oil and gas barrels within pressure to basic hydraulic. Air compressor in no-load operation, continuous loading solenoid valve after loss of power 20min, the system enters the empty for too long to stop State.
(4) volume adjustment. Empty pressure machine loaded process in the for reduced empty pressure machine of empty heavy load times, installation has anti-proportion valve, dang unit pressure reached pressure switch ceiling Qian anti-proportion valve ahead of action, reduced to servo cylinder of gas volume, into valve servo cylinder valve Rod thrust reduced, in spring force of role Xia valve Rod back shrink, dang spring force and cylinder of gas thrust balance Shi, valve rod in half open State, intake volume reduced achieved empty pressure machine of capacity regulation.
(5) service. Stop signal from the empty too long or pressure for long periods at a maximum pressure of the system, the motor stops, the host stops no longer breathe, inlet valve internal check valve quickly closes to ensure no downtime of spitting oil, pressure relief valve vented to the outside atmosphere.
