簡(jiǎn)單為你介紹：1、先導(dǎo)式：通電時(shí)，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(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷                       電時(shí)，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(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。

                      2、直動(dòng)式：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。  簡(jiǎn)略：                        先導(dǎo)式電磁閥需要以工作介質(zhì)的壓力支撐做為開閥的第2條件。直動(dòng)式則僅                       依靠電磁力進(jìn)行工作。
