品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005…进口微型直动式电磁阀通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭
工作原理 working principle
进口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
