style="text-indent:25px">先導式電磁閥原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。電磁閥從閥結(jié)構和材料上的不同與原理上的區(qū)別，分為六個分支小類：直動膜片結(jié)構、分步直動膜片結(jié)構、先導膜片結(jié)構、直動活塞結(jié)構、分步直動活塞結(jié)構、先導活塞結(jié)構。電磁閥按照功能分類：水用電磁閥、蒸汽電磁閥、制冷電磁閥、低溫電磁閥、燃氣電磁閥、消防電磁閥、氨用電磁閥、氣體電磁閥、液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥常開電磁閥、油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。</p><p style="text-indent:25px">直動式電磁閥，通電時，電磁線圈產(chǎn)生電磁力把關閉件從閥座上提起，閥門打開;斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。它是一種直動和先導式相結(jié)合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，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，先導閥利用彈簧力或介質(zhì)壓力推動關閉件，向下移動，使閥門關閉。特點:在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。在零壓差或真空、高壓時亦可動作，但功率較大，要求必須水平安裝。電磁閥適合一些特殊地工藝要求，比如泄漏、流體介質(zhì)特殊等，價格較貴。</p><div
