電液換向閥是電磁換向閥和液控換向閥的組合，它是用電磁換向閥控制液控換向閥的動作，變換流體流動方向的控制閥。
電液換向閥和液控換向閥主要用在流量超過電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對執(zhí)行元件的動作進行控制，或對油液的流動方向進行控制。
說明事項 1. 產品可任意安裝，優(yōu)先考慮水平位置。
2. 液壓系統(tǒng)所用介質必須過濾，過濾精度至少20μm。
3. 固定螺釘請按樣本中所列參數(shù)選用。
4. 與閥連接的表面，粗糙度要求Ra0.8，平面度要求0.01/100mm
工作原理：
當兩個電磁閥線圈通電時，平衡孔回路關閉，泄流孔回路打開，活塞上腔泄壓，活塞上行，閥門打開。反之，活塞下行，閥門關閉。在閥門開啟和關閉過程中，可將流量（流速）信號及閥塞位置信號傳送給計算機，經(jīng)過計算機處理后發(fā)出相應的指令，控制兩個電磁導閥的通、斷電狀態(tài)，使活塞的上下腔的液壓差產生變化，從而將活塞控制在所需的開啟高度上，實現(xiàn)對管道介質流量的控制。
