RETZ工业/美国瑞茨，我们一直致力于流体控制领域的持续创新，始于2005……进口过滤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
进口过滤直动式电磁阀有常闭型常开型二种 retzThere are two types of imported filter direct acting solenoid valves: normallyclosed 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。Whenthe normally closed type is powered off, it is in a closed state. When the coilis energized, electromagnetic force is generated, causing the moving iron coreto overcome the spring force and the static iron core to directly open thevalve port, and the medium passes through; When the coil loses power, theelectromagnetic force disappears, and the moving iron core recovers under theaction of spring force Position, directly close the valve port, medium blocked
2. 常开型正好相反的工作原理Theopposite working principle of the normally open type
