寶德一級(jí)代理burkert電磁閥5404BURKERT電磁閥同時(shí)依靠介質(zhì)壓力，主副閥得以緊密關(guān)閉。常開(kāi)電磁閥，線圈通電后由于吸力作用，動(dòng)鐵芯下移，把副閥閥塞壓下，副閥關(guān)閉，主閥閥杯內(nèi)壓力上升，當(dāng)壓力升到一定值時(shí)，主閥閥杯的上下壓差一樣，由于電磁力作用，動(dòng)鐵芯推動(dòng)主閥閥杯下，壓緊主閥閥座，閥門(mén)關(guān)閉。線圈斷電時(shí)，電磁吸力為零，副閥閥塞和動(dòng)鐵芯由于彈簧作用向上提起，副閥打開(kāi)，主閥閥杯上的流體經(jīng)副閥流走，減少了作用在主閥閥杯上的壓力，當(dāng)主閥閥杯上的壓力減少到一定值時(shí)，利用壓差把主閥閥杯推起，主閥打開(kāi)，介質(zhì)流通。The baode primary agent burkert solenoid valve 5404BURKERT solenoid valve also relies on medium pressure, the main auxiliary valve can close tightly. Normally open solenoid valve and coil electricity due to the suction effect, after moving iron core down, the deputy valve plug pressure, the deputy valve closed, pressure rise within the main valve cup, when the pressure rises to a certain value, the main valve cup of fluctuation pressure difference, due to the electromagnetic effect, promote the main valve cup of moving iron core, the pressure the main valve seat, the valve closed. Coil power, electromagnetic suction is zero, the deputy valve plug and due to the spring action of moving iron core lift, vice valve is opened, the fluid by the deputy valve on the main valve cup run, reduce the pressure effect on the main valve cup, when the main valve cup pressure was reduced to a certain value, the use of differential pressure push the main valve cup, the main valve opens, medium circulation.
