From a functional viewpoint groups of solenoid valves

are identical to the singles. The only difference is that

they can be put together to form a group of solenoid

valves with an inlet pipe and various outlet pipes, each

one of which can be opened by energizing the corresponding coil

3路常闭电磁阀有入口管，a出口管和排气管。 

柱塞，其上两个垫圈被安装，直接用于打开和关闭电磁阀的主节流孔与两个气体喷头之一，

同时打开或关闭出口孔与其他垫片。 

当线圈未通电时柱塞处于使主孔关闭的位置，将流体从入口管流出到出口管，

而出口管与排气管连通管。

当线圈通电时，柱塞移动到位置其打开主孔并关闭排气孔，

In this family of solenoid valves an increase in inlet pressure

causes a reduction in the force required to open the valve: if the

inlet pressure is greater than the maximum value for which the

solenoid valve has been designed, the latter may open even

when the coil is not energized.

密封盖垫片配合的柱塞直接用于打开和关闭孔口，如同双向常闭电磁阀。

当线圈未通电时，柱塞处于这样的位置

关闭孔口，防止流体从入口流出到出口管。

当线圈通电时，柱塞移动到一个位置打开孔口，允许流体从入口流到出口管。

除了打开和关闭孔口之外，盖垫圈还有助于保持流体与电枢管不完全的柱塞分离，并避免灰泥沉积在电枢管。

在出口管上通常有一个调节螺丝，用于固定电磁阀的流动，分配导管。

On the lower body of the solenoid valves for automatic drink-dispensers there is also a little

venting fitting, on which usually a plastic pipe is connected.

This device assures a better fluid efflux, and therefore a steady flow

允许流体从入口管流到出口1和防止流向排气。

在这些阀门上，与其他型号不同，流体应进入进入阀门，以便通过主孔口下侧向较高的一侧。
