可分為手動換向閥、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，可適時改變流體流向。工作時借著閥外的驅(qū)動傳動機構(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***的應(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。作用：換向閥是利用閥芯在閥體孔內(nèi)作相對運動，使油路接通或切斷而改變油流方向的閥。換向閥的分類按結(jié)構(gòu)形式可分：滑閥式、轉(zhuǎn)閥式、球閥式。按閥體連通的主油路數(shù)可分：兩通、三通、四通…等。按閥芯在閥體內(nèi)的工作位置可分：兩位、三位、四位等。按操作閥芯運動的方式可分：手動、機動、電磁動、液動、電液動等。1、手動換向閥手動換向閥是手動杠桿操作的方向控制閥，在液壓系統(tǒng)中起換向（改變液流方向）和開關(guān)（接通或切斷液流）作用。2機動換向閥機動換向閥又稱行程閥，主要用來控制機械運動部件的行程，借助于安裝在工作臺上的檔鐵或凸輪迫使閥芯運動，從而控制液流方向。瑯琊區(qū)導(dǎo)流閥門廠家電話閘閥運動件失效模式主要為閥桿頭部剪切失效及閘板T形槽彎曲失效，其中又以閘板T形槽彎曲失效為主。</p><div
