style="text-indent:25px">直動(dòng)式電磁閥：原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。特點(diǎn)：在真空、負(fù)壓、零壓時(shí)能正常工作，但通徑一般不超過25MM。分布直動(dòng)式電磁閥：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。分布直動(dòng)式電磁閥特點(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。</p><div
