進口過濾直動式電磁閥通電時，電磁線圈產(chǎn)生電磁力把關閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉

工作原理 working principle

進口過濾直動式電磁閥有常閉型常開型二種 retz There are two types of imported filter direct acting solenoid valves: normally closed and normally open

1. 常閉型斷電時呈關閉狀態(tài)，當線圈通電產(chǎn)生電磁力，使動鐵芯克服彈簧力和靜鐵芯吸合直接開啟閥口，介質(zhì)通過；當線圈斷電時電磁力消失，動鐵芯在彈簧力的作用下復位，直接關閉閥口，介質(zhì)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. 常開型正好相反的工作原理The opposite working principle of the normally open type
