結(jié)構(gòu)簡(jiǎn)單，動(dòng)作可靠，開(kāi)關(guān)速度快，在零壓差和微真空下正常工作 Simple structure, reliable action, fast switching speed, and normal operation under zero pressure difference and micro vacuum

工作原理 working principle

常閉型斷電時(shí)呈關(guān)閉狀態(tài)，當(dāng)線圈通電產(chǎn)生電磁力，使動(dòng)鐵芯克服彈簧力和靜鐵芯吸合直接開(kāi)啟閥口，介質(zhì)通過(guò)；當(dāng)線圈斷電時(shí)進(jìn)口過(guò)濾直動(dòng)式電磁閥，電磁力消失，動(dòng)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。

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
