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(guò)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(kāi)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。

(1)六通閥的閥體由隔板分成兩腔，每腔都有3個(gè)通道，中間為進(jìn)油口，兩端為出油口。閥體為碳鋼板焊結(jié)構(gòu)，體積小，質(zhì)量輕，結(jié)構(gòu)緊湊，提高了材料的利用率，縮短了周期，降低了成本。密封面堆焊不銹鋼，防銹耐腐蝕，密封面經(jīng)過(guò)精加工后拋光研磨，表面粗糙度Ra≤0.8μm。
(2)六通閥有兩組密封組件。每組密封組件(圖2)由閥瓣、密封圈、調(diào)整塊、調(diào)節(jié)螺釘、夾板和螺栓組成。閥瓣為碳鋼板焊件，設(shè)有加強(qiáng)筋，即增加閥瓣強(qiáng)度又起導(dǎo)向作用，保證每組閥瓣間的同軸度。閥瓣上鑲嵌聚氨脂橡膠圈，該材料具有耐油、耐磨損、穩(wěn)定、密封良好和壽命長(zhǎng)的特點(diǎn)。在凸輪的作用下，密封圈的球面與閥體密封面相接觸產(chǎn)生擠壓彈性變形，達(dá)到密封。調(diào)整塊和調(diào)節(jié)螺釘在兩組密封組件不能同步到位時(shí)可起調(diào)整作用，確保各通道密封同步到位。

(3)閥桿與閥體隔板和上閥蓋間的軸向密封采用O形圈。
(4)閥體隔板及上閥蓋軸孔部位鑲有銅套，可減小與O形圈間的摩擦力矩，密封組件開(kāi)啟與關(guān)閉靈活，操作力矩小。
(5)上閥蓋設(shè)有指示牌及限位螺釘，閥桿上安裝指針，明確指示各通道的接通狀況，易于操作。
