換向閥
換向閥是具有兩種以上流動(dòng)形式和兩個(gè)以上油口的 方向控制閥。是實(shí)現(xiàn)液壓油流
的溝通、切斷和換向,以及壓力卸載和順序動(dòng)作控制的閥門(mén)。可分為手動(dòng)換向閥、
電磁換向閥、電液換向閥等。
又稱(chēng)克里斯閥,閥門(mén)的一種,具有多向可調(diào)的通道,可適時(shí)改變流體流向。
工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸,帶動(dòng)搖拐臂,啟動(dòng)閥板,使工作 流
體時(shí)而從左入口通向閥的下部出口,時(shí)而人右入口變換通向下部出口,實(shí)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)中最為常用。
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(chǎng)合。工作時(shí)只需轉(zhuǎn)動(dòng)手 輪
通過(guò)閥瓣來(lái)變換工作流體的流向。
閥板式的優(yōu)點(diǎn)是動(dòng)作準(zhǔn)確、自動(dòng)化程度高、工作穩(wěn)定可靠,但需附設(shè)驅(qū)動(dòng)和冷 卻
系統(tǒng),結(jié)構(gòu)較為復(fù)雜;閥瓣式結(jié)構(gòu)則較簡(jiǎn)單,多用于流量較小的生產(chǎn)工藝上。
