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(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***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(jī)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(jī)動換向閥機(jī)動換向閥又稱行程閥，主要用來控制機(jī)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。合肥壓力開關(guān)閥門廠家電話</p><p
