進口黃銅、不銹鋼膜片直動式電磁閥采用常閉型工作原理 retz The imported brass diaphragm direct acting solenoid valve adopts a normally closed working principle

斷電時呈關閉狀態，當線圈通電產生電磁力，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
