3、電磁換向閥利用電磁鐵的通電吸合與斷電釋放而直接推動(dòng)閥芯來(lái)控制液流方向。它是電氣系統(tǒng)和液壓系統(tǒng)之間的信號(hào)轉(zhuǎn)換元件。電磁換向閥是利用電磁鐵吸力推動(dòng)閥芯來(lái)改變閥的工作位置。因?yàn)樗梢钥刂菩盘?hào)發(fā)送到一個(gè)按鈕開(kāi)關(guān)，行程開(kāi)關(guān)，限位開(kāi)關(guān)，壓力繼電器，使用操作簡(jiǎn)單，易于實(shí)現(xiàn)自動(dòng)化，所以***應(yīng)用。電磁換向閥的作用是它可以改變控制液流的方向，從而改變液動(dòng)換向閥的位置。由于操縱液動(dòng)換向閥的液壓推力可以很大，所以主閥可以做得很大，允許有較大的流量通過(guò)。這樣用較小的電磁鐵就能控制較大的液流。電磁換向閥工作原理是，通過(guò)電磁鐵控制滑閥閥芯的不同位置，以改變形油液的流動(dòng)方向。變換閥心在閥體內(nèi)的相對(duì)工作位置，使閥體各油口連通或斷開(kāi)，從而控制液壓執(zhí)行元件（如液壓桿、液壓馬達(dá)）的換向或啟停。當(dāng)電磁鐵斷電時(shí)，滑閥由彈簧保持在中間位置或初始位置（脈沖式閥除外）。若推動(dòng)故障檢查按鈕可使滑閥閥芯移動(dòng)。4、其它閥門按閥的工作位置分類閥的工作位置稱為“位”，有幾個(gè)切換工作位置的閥就稱為“幾位”閥。經(jīng)常使用的有“二位”閥和“三位”閥。閥在未加控制信號(hào)或**作時(shí)所處的位置稱為零位。按閥的接口數(shù)目分類閥的接口（包括排氣口）稱為“通”。埇橋區(qū)緩閉止回閥門供應(yīng)商下游聲場(chǎng)強(qiáng)度受影響很小，但對(duì)聲場(chǎng)的指向性影響很大。</p><div
