換向閥是實(shí)現(xiàn)液壓油流的溝通、切斷和換向，以及壓力卸載和順序動(dòng)作控制的閥門(mén)，是具有兩種以上流動(dòng)形式和兩個(gè)以上油口的方向控制閥。可分為手動(dòng)換向閥、電磁換向閥、電液換向閥等。工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸，帶動(dòng)搖拐臂，啟動(dòng)閥板，使工作流體時(shí)而從左入口通向閥的下部出口，時(shí)而從右入口變換通向下部出口，實(shí)現(xiàn)了周期變換流向的目的。手柄逆時(shí)針旋轉(zhuǎn)，兩組密封組件分別在凸輪的作用下關(guān)閉下端的兩個(gè)通道，上端的兩個(gè)通道分別與管道裝置的進(jìn)口相通
