單向閥的作用:
(1)普通單向閥的作用是使油液只能沿著一個方向流動,不允許反向倒流.
(2)它的用途是:安裝在泵的出口,可防止系統壓力沖擊對泵的影響,另外,泵不工作時,可防止系統油液經泵倒流回油箱,單向閥還可用來分隔油路,防止干擾.單向閥與其他閥組合便可組成復合閥.單向閥與其他閥可組成液控復合閥
(3)對于普通液控單向閥,當控制口無控制壓力時,其作用與普通單向閥一樣;當控制口有控制壓力時,通油口接通,油液便可在兩個方向自由流動.
(4)它的主要用途是:可對液壓缸進行鎖閉;作立式液壓缸的支承閥;起保壓作用.

單向閥是氣流只能一個方向流動而不能反向流動的方向控制閥。其工作原理與液壓單向閥一樣。壓縮空氣從P口進入,克服彈簧力和摩擦力使單向閥閥口開啟,壓縮空氣從P流至A;當P口無壓縮空氣時,在彈簧力和A口(腔)余氣力作用下;閥口處于關閉狀 態,使從A至P氣流不通。單向閥應用于不允許氣流反向流動的場合,如空壓機向氣罐充氣 時,在空壓機與氣罐之間設置一單向閥,當空壓機停止工作時,可防止氣罐中的壓縮空氣回流 到空壓機。單向閥還常與節流閥、順序閥等組合成單向節流閥、單向順序閥使用。
