结构原理             丹富斯电磁阀/电磁阀作用
本阀通径15～100为膜片式为二次开阀的先导式电磁阀，通径125～300为三次开阀的先导式电磁阀，其结构主要由副阀和主阀组成。根据断电时所处开关状态的不同，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。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门外世，以致主阀阀杯上下产生压力差，膜片或阀杯被迅速托起主阀口开启，阀呈通路状态。
当线圈断电，磁场消失，活动铁芯复位，封闭副阀口，继而副阀和主阀阀杯内压力上升，主阀阀杯压向阀座，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，随着主阀阀杯上下压差趋向相等，主阀阀杯由自重压向密封面，阀门关闭。当线圈断电后，磁力为零，衔铁祁副阀阀杯由于弹簧作用上升，副阀打开，主阀阀杯内介质经副阀流走，压力下降，当压力降到一定值后，主阀阀杯由上下压差作用向上升起，主阀打开，阀门开启。   

Dan fuss with ZCS water electromagnetic valve product overview

Structure principle 
This valve size 15 ~ 100 for diaphragm for secondary open valve guiding type solenoid valve, size of 125 ~ 300 for three open valve guiding type solenoid valve and its structure is mainly composed of pair of valve and main valve. Depending on the power of switch state, can be divided into the normally closed solenoid valve solenoid valve and it always open. Normally closed electromagnetic valves, and often, activity core sealed vice valve mouth, cavity pressure balance, the deputy valve, main valve closed. Electricity, when the winding electromagnetic force: the core activity on the absorption, vice valve is opened, the main valve cavity medium homing valve outside the world, so that the main valve cup of fluctuation pressure difference, diaphragm valve or cup was quickly in order to the main valve mouth open, valve distribution state. 
Disappear, when the coil power, magnetic activity core reset, the deputy valve closed mouth, then vice valve and pressure rise within the main valve cup, the main valve cup pressure to the valve seat, valve is closed. 
Normally open solenoid valve, when the coil electricity, magnetic, armature down, under the action of a magnetic drive vice valve cup down, the deputy valve closed, as the main valve cup of fluctuation pressure differential approach parity, the main valve cup by the pressure to the sealing surface, the valve closed. After the power coil, magnetic force is zero, armature qi vice valve cup due to the increasing spring action, the deputy valve is opened, the main valve cup in the medium run by the deputy valve, pressure drop, when pressure is below a certain value, the main valve cup by the pressure differential action rises up and down, open the main valve, the valve opens.
