结构原理                     
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 solenoid valve product overview
This series solenoid valve is suitable for water or liquid, the gas as medium, two entry level, concentration, flow rate, measurement or discharge cycle automatically controls the on-off switch two port two type or normally closed normally open.

The structure principle
The valve diameter 15 ~ 100 for the diaphragm for the pilot solenoid valve two open valve, diameter 125 ~ 300 for the pilot solenoid valve three to open the valve, which is mainly composed of a pair of valve and main valve. According to the state when the power switch is different, can be divided into the normally closed solenoid valve and a normally open electromagnetic valve. Normally closed solenoid valve, constant position, the movable iron core sealed side valve port, the valve cavity pressure balance valve, the main valve port closed side. When the coil power, the electromagnetic force generated: will absorb the core activities, vice valve is opened, the main valve chamber of the media self guided valve to the outside world, so that the main valve valve cup upper and lower pressure difference is generated, the diaphragm or valve cup was quickly hold up the opening of the main valve is opened, the valve was channel state.
When the coil power the magnetic field disappeared, moving core reset, vice valve closed mouth, then vice valve and main valve valve cup pressure rise, the main valve valve cup pressure to the valve seat, valve then was closed.
Normally open solenoid valve, when the coil is energized, the armature magnetic force is generated, under the action of magnetic force down, push down vice valve cup, the Deputy valve closed, with the main valve valve cup pressure difference under the same trend, the main valve valve cup by the self weight of the sealing surface, the valve closed. When the coil power, the magnetic force is zero, the armature Qi vice valve cup due to the action of the spring rises, vice valve is opened, the main valve valve cup medium flow out by the vice valve, pressure drop, when the pressure dropped to a certain value, the main valve valve cup is composed of upper and lower pressure difference rises up, the main valve is opened the valve opening.
