換向閥是具有兩種以動(dòng)形式和兩個(gè)以上油口的方向控制閥。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。
雙向換向閥
可分為手動(dòng)換向閥、電磁換向閥、電液換向閥等。
又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時(shí)改變流體流向。
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。
這種變換閥在石油、化工生產(chǎn)中有著應(yīng)用，在合成氨造氣系統(tǒng)中為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場(chǎng)合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過閥瓣來變換工作流體的流向。
2工作原理
六通換向閥主要由閥體、密封組件、凸輪、閥桿、手柄和閥蓋等零部件組成(圖1)。閥門由手柄驅(qū)動(dòng)，通過手柄帶動(dòng)閥桿與凸輪旋轉(zhuǎn)，凸輪具有定位驅(qū)動(dòng)與鎖定密封組件的開啟與關(guān)閉功能。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。反之，上端的兩個(gè)通道關(guān)閉，下端兩個(gè)通道與管道裝置的進(jìn)口相通，實(shí)現(xiàn)了不停車換向。
