換向閥又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時改變流體流向?？煞譃槭謩訐Q向閥、電磁換向閥、電液換向閥等。

工作時借著閥外的驅(qū)動傳動機(jī)構(gòu)轉(zhuǎn)動驅(qū)動軸，帶動搖拐臂，啟動閥板，使工作流體時而從左入口通向閥的下部出口，時而從右入口變換通向下部出口，實現(xiàn)了周期變換流向的目的。

這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中較為常用。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合。工作時只需轉(zhuǎn)動手輪通過閥瓣來變換工作流體的流向。

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，通過手柄帶動閥桿與凸輪旋轉(zhuǎn)，凸輪具有定位驅(qū)動與鎖定密封組件的開啟與關(guān)閉功能。手柄逆時針旋轉(zhuǎn)，兩組密封組件分別在凸輪的作用下關(guān)閉下端的兩個通道，上端的兩個通道分別與管道裝置的進(jìn)口相通。反之，上端的兩個通道關(guān)閉，下端兩個通道與管道裝置的進(jìn)口相通，實現(xiàn)了不停車換向。
