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閥芯來控制液流方向。它是電氣系統(tǒng)和液壓系統(tǒng)之間的信號轉(zhuǎn)換元件。電磁換向閥是利用電磁鐵吸力推動閥芯來改變閥的工作位置。因為它可以控制信號發(fā)送到一個按鈕開關(guān)，行程開關(guān)，限位開關(guān)，壓力繼電器，使用操作簡單，易于實現(xiàn)自動化，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，從而改變液動換向閥的位置。由于操縱液動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。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，通過電磁鐵控制滑閥閥芯的不同位置，以改變形油液的流動方向。變換閥心在閥體內(nèi)的相對工作位置，使閥體各油口連通或斷開，從而控制液壓執(zhí)行元件（如液壓桿、液壓馬達）的換向或啟停。當電磁鐵斷電時，滑閥由彈簧保持在中間位置或初始位置（脈沖式閥除外）。若推動故障檢查按鈕可使滑閥閥芯移動。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。閥在未加控制信號或被操作時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”。有助生飲

節(jié)能：因為是主要依靠電力作為動能，所以電動調(diào)節(jié)閥只在工作時才消耗電能; </p> <p> 安裝方便：相比氣動調(diào)節(jié)閥，電動調(diào)節(jié)閥無需復(fù)雜的氣動管路和氣泵工作站; </p> <p> 可靠性：在過去，普遍認為氣動調(diào)節(jié)閥的可靠性要好，但是隨著技術(shù)的進步，新一代的電動調(diào)節(jié)閥執(zhí)行機構(gòu)采用全電子式集成化電路，其可靠性已經(jīng)可以和氣動調(diào)節(jié)閥平分秋色了。 </p> <p> 價格：因為氣動調(diào)節(jié)閥具有安全防爆的優(yōu)點，需要建立一套空壓站，而增加了成本費用，所以基本上在安全防爆要求不高的情況下，優(yōu)先選擇電動調(diào)節(jié)閥。 </p> <p> 維護成本：和其他調(diào)節(jié)閥相比，電動調(diào)節(jié)閥還有一個優(yōu)勢，就是后期的維護成本要低很多。蜀山區(qū)旋流防止閥門供應(yīng)商</p><p
