style="text-indent:25px">分步直動(dòng)式電磁閥一般是用于壓力不穩(wěn)定的場(chǎng)合，零壓可啟動(dòng)，壓力上限也較大，即0-0.6MPa也可0-1.6MPa，口徑范圍也比直動(dòng)式的更廣，特別適合口徑大，零壓可動(dòng)作，有壓力能使用的場(chǎng)所。原理：它是一種直動(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，閥門打開。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；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)，使閥門關(guān)閉。特點(diǎn)：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。三明不銹鋼電磁閥排行榜不銹鋼電磁閥的作用是快速地切斷和接通氣源。</p><div
