力士樂(lè)電磁閥有干式和濕式兩者區(qū)別

1，電磁閥有干式和濕式兩者區(qū)別在于，電磁閥的鐵芯是否浸在油里。（1）干式電磁閥不允許油液 進(jìn)入電磁鐵內(nèi)部，因此推動(dòng)閥芯的推桿處要有可靠的密封，從而使推桿移動(dòng)時(shí)產(chǎn)生較大的摩擦阻力。（2）濕式電磁閥的銜鐵和推桿可浸在油中工作，所以電磁鐵的相對(duì)運(yùn)動(dòng)件之間就不需要密封裝置，這就減少了閥芯的運(yùn)動(dòng)阻力，提高了換向可靠性，濕式電磁鐵性能較好。2，電磁閥從原理上分為三大類：（1）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(kāi)；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。（2）分步直動(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(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(kāi)。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(kāi)；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。（3）先導(dǎo)式電磁閥，原理：通電時(shí)，電磁力把先導(dǎo)孔打開(kāi)，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(kāi)；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過(guò)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。

電磁換向閥是電磁閥的一種類型。
閥門：是流體輸送系統(tǒng)中的控制部件,具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。
電磁閥：是用電磁控制的閥門，是用來(lái)控制流體的自動(dòng)化基礎(chǔ)元件之一。泛指所有用電磁控制的閥門；特指（與其它具有說(shuō)明的電磁閥，如三通電磁閥、電磁幻象閥……并列的情況下）僅具有截止、導(dǎo)流功能的電磁閥。
電磁換向閥：泛指可以控制介質(zhì)流向的電磁閥。特指液壓、氣動(dòng)控制系統(tǒng)中用于實(shí)現(xiàn)控制邏輯的換向閥。
