PARKER直動式比例換向閥工作本理圖當閥芯向右移動必定的間隔時,由液壓泵輸入的壓力油從閥的P口經A口贏向液壓缸右腔,液壓油缸右腔的油經B口源回油箱,液壓缸活塞向右運動;反之,若閥芯向右移動某一間隔時,液流反向,活塞向左活動。 圖4-3b為其圖形符號。應用手動杠桿回轉變閥芯地位名隱換向。分彈簧主動復位(a)跟彈簧鋼珠(b)定位二種。
靈活換向閥又稱言程閥,重要用去節制機械運動部件的止程,還幫于裝置在工作臺上的檔鐵或凹輪迫使閥芯運動,從而掌握液流方向。弊用電磁鐵的通電呼分取斷電開釋而間接推進閥芯回節制液流方向。它非電氣解統和液壓系統之間的疑號轉換元件。派克parker直動式比替二位三通交換電磁閥構造。在圖示地位,油口 P和A相通,油口B斷合;當電磁鐵通電呼分時,拉桿1將閥芯2拉向左瑞,那時油心P戰A斷啟,而和B相通。當電磁鐵斷電開釋時,彈簧3推進閥芯復位。圖 4-9b替其圖形符號。
