BURKERT直供 5281寶德系列電磁閥是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒(méi)有壓差時(shí),通電后,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,閥門(mén)打開(kāi)。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,電磁力先導(dǎo)小閥,主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開(kāi);斷電時(shí),先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,向下移動(dòng),使關(guān)閉。
在零壓差或真空、高壓時(shí)亦能可動(dòng)作,但功率較大,要求必須水平安裝。

It is a principle of the combination of direct motion and lead. When the inlet and outlet are free of differential pressure, the electromagnetic force will directly lift the pilot valve and the main valve close in turn, and the valve will open. When the inlet and outlet reach the starting pressure difference, when the power is energized, the electromagnetism first pilot small valve, the pressure of the lower cavity of the main valve increases, the upper chamber pressure drops, so that the main valve is pushed up by the pressure difference; When the power is off, the pilot valve USES the spring force or medium pressure to push the closure, moving down and closing.
In the zero pressure difference or vacuum, high pressure can also be able to move, but the power is larger, the requirement must be installed horizontally.
