             空气、水液电磁阀为膜片式二次开阀的先导式电磁阀，其结构主要由副阀和主阀组成。根据断电时所处状态的不同，减压阀可分为常闭电磁阀和常开电磁阀。常闭电磁阀，常位时，活动铁芯封住副阀口，阀腔内压力平衡，副阀、主阀口封闭。针型阀当线圈通电，产生电磁力将活动铁芯吸上，副阀打开，主阀腔内的介质自导阀口外泄，以致主阀膜片上下产生压力差，膜片被迅速托起，主阀口开启，阀呈通路状态。当线圈断电，调节阀磁场消失，活动铁芯复位，封闭副阀口，继而副阀膜片上腔压力上升，主阀膜片压向阀座，阀又呈关闭状态。

　　 常开电磁阀，当线圈通电时，产生磁场力，衔铁在磁力作用下下移，推动副阀阀杯下移，副阀关闭，随着主阀阀内上下压差趋向相等，锻钢阀门主阀膜片由弹簧力及自重压向密封面，阀门关闭。当线圈断电后，磁力为零，呼吸阀衔铁和副阀阀杯由于弹簧作用上升，副阀打开，主阀膜片上腔内介质经副阀流走，压力下降，当压力降到一定值后，主阀由上下压差作用向上升起，主阀打开，空气、水液电磁阀开启。

           Air, water, liquid solenoid valve to open the second valve diaphragm pilot operated solenoid valve, is structured by the Deputy valve and main valve. According to the state in which the different power failure, can be divided into normally closed solenoid valve and the normally open solenoid valve. Normally closed solenoid valve, often Filterof places, activities vice valve core seal the mouth of the pressure balance valve cavity, vice valve, main valve port closed. When the coils to generate electromagnetic force will absorb the core activities of the DeputyNeedle Valves valve is opened, the main valve chamber of the media self-guided valve port leakage, resulting in up and down the main valve diaphragm produces pressure difference, diaphragm was quickly hold up, the main valve port Open the valve was channel state. When the coil power, the magnetic field disappeared, activities core reset,Automatic Control Valves Vice valve closed mouth, then Vice-valve diaphragm on the chamber pressure rise, the main valve diaphragm pressure to the valve seat, valve then was closed. Normally open solenoid valve, when the coils, the magnetic field strength, the magnetic effect of the armature down, push down, vice valve cup, the Deputy valve closed, with the main valveBellow Seal Valves pressure difference within the same trend, the main valve diaphragm by the spring force and self weight of the sealing surface, the valve closed. When the coil power, the magnetic force is zero,Forged Steel Valves keeper and vice-function valve cup spring up as the Deputy valve is opened, the main valve diaphragm valve on the medium in the cavity flow away by the deputy, pressure drop, when the pressure dropped to a certain value, the main valve by the pressure difference rises up and down the main valve open, air, water, liquid solenoid valve to open.
