DLOH-2C-UX-24DC/WG充液閥是一種特殊的液控單向閥，一個(gè)方向止流，另一個(gè)方向自由流通，先導(dǎo)動(dòng)作是由油口供壓的控制閥芯用液壓實(shí)現(xiàn)的，由此而直接打開(kāi)主閥。這種閥為疊加系統(tǒng)而設(shè)計(jì)，即在一個(gè)基礎(chǔ)件上，可以疊加各種各樣的其它類別液壓閥。其主要作用是從油箱（或充液油箱）向液壓缸或者系統(tǒng)補(bǔ)充油液，以免出現(xiàn)吸空現(xiàn)象。帶控制的充液閥還能起快速排油的作用。

2.2充液閥的典型結(jié)構(gòu)

充液閥有常閉式和常開(kāi)式兩種典型結(jié)構(gòu)。電磁方向閥 DHU-0631/WP 24DC

(1)常閉式充液閥

常閉式充液閥有不可控式和可控式兩種形式，不可控式充液閥，它是由閥芯、導(dǎo)向套、復(fù)位彈簧、閥體和連接法蘭等主要零件組成。閥芯是蘑菇形的，結(jié)構(gòu)較緊湊，流阻損失?。婚y芯重量輕慣性小，動(dòng)作靈敏。
