工作原理 working principle

进口黄铜、不锈钢微型直动式电磁阀有常闭型常开型二种 retz There are two types of imported brass and stainless steel micro direct acting solenoid valves: normally closed and normally open

1.常闭型断电时呈关闭状态，当线圈通电产生电磁力，使动铁芯克服弹簧力和静铁芯吸合直接开启阀口，介质通过；当线圈断电时电磁力消失，动铁芯在弹簧力的作用下复

位，直接关闭阀口，介质不通。

When the normally closed type is powered off, it is in a closed state. When the coil is energized, electromagnetic force is generated, causing the moving iron core to overcome the spring force and the static iron core to directly open the valve port, and the medium passes through; When the coil loses power, the electromagnetic force disappears, and the moving iron core recovers under the action of spring force Position, directly close the valve port, medium blocked

2.常开型正好相反的工作原理

The opposite working principle of the normally open type
