進(jìn)口過(guò)濾直動(dòng)式電磁閥 美國(guó)RETZ瑞茨

品牌：RETZ瑞茨/我們一直致力于流體控制領(lǐng)域的持續(xù)創(chuàng)新，始于2005……

進(jìn)口過(guò)濾直動(dòng)式電磁閥通電時(shí)，電磁線(xiàn)圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門(mén)打開(kāi)；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門(mén)關(guān)閉

工作原理 working principle

進(jìn)口過(guò)濾直動(dòng)式電磁閥有常閉型常開(kāi)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(shí)呈關(guān)閉狀態(tài)，當(dāng)線(xiàn)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(xiàn)圈斷電時(shí)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

2.       常開(kāi)型正好相反的工作原理The opposite working principle of the normally open type
