美國(guó)PARKER電控4/3或4/2通換向閥D41VW系列D41VW004C1NJW3R

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(mén)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(chē)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,縮短了生產(chǎn)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、性能穩(wěn)定、密封良好和使用壽命長(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)到密封效果。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,確保各通道密封性能同步到位。

（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。
