工作原理 working principle
1.常閉型斷電時呈關(guān)閉狀態(tài),當(dāng)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(dāng)線圈斷電時電磁力消失,動鐵芯在彈簧力的作用下復(fù)
位,直接關(guān)閉閥口,介質(zhì)不通。retz
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
