不同類型電磁閥的工作原理
追朔電磁閥的發(fā)展史，到目前為止，國內(nèi)外的電磁閥從原理上分為三大類(即:直動式、分步童先導(dǎo)式)，而叢閥瓣結(jié)構(gòu)和材料
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(dǎo)小液，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(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件，向下移動，使閥門關(guān)閉。特點:在零壓差或真空、高
壓時亦能可動作，但功率較大，要求必須水平安裝。先導(dǎo)式電磁閥:
原理:通電時，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān)閉件周圍形成上低下高的壓差，流體壓力推動關(guān)閉件向上移動，
閥門打開;斷電時，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動關(guān)閉件
向下移動，關(guān)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。
