液壓系統(tǒng)單向節(jié)流閥的結(jié)構(gòu)及工作原理
單向節(jié)流閥由單向閥和節(jié)流閥并聯(lián)而成,用于一個方向需要控制流量而另一個方向(反向)需要油流暢通的回路中,以實(shí)現(xiàn)執(zhí)行元件正向可調(diào)速,而反向能快速退回。
下面就帶大家來了解下單向節(jié)流閥的結(jié)構(gòu)及其工作原理。
圖1所示爲(wèi)滑閥壓差式單向節(jié)流閥。當(dāng)油液從P1流向P2時,閥起節(jié)流閥作用,反向時起單向閥作用。閥芯4下端和上端分別受進(jìn)、出油腔壓力油的作用,在進(jìn)出油腔壓差和複位彈簧6的作用下,閥芯緊壓在調(diào)節(jié)螺釘2上,以保持原來調(diào)節(jié)好的節(jié)流口開度。

圖2所示爲(wèi)可以直接安裝在管路上的單向節(jié)流閥。節(jié)流口爲(wèi)軸向三角槽式結(jié)構(gòu),旋轉(zhuǎn)調(diào)節(jié)套3,可以改變節(jié)流口通流面積的大小,實(shí)現(xiàn)流量調(diào)節(jié)。正向流動時(B→A)起節(jié)流閥作用;反向流動時(A→B)起單向閥作用,由于有部分油液可在環(huán)形縫隙中流動,可以清除節(jié)流口上的沉積物。閥芯左端有刻度槽,調(diào)節(jié)套上有刻度圈,以標(biāo)志調(diào)節(jié)流量的大小。該閥流量調(diào)節(jié)須在無壓力下進(jìn)行。博士力樂士系列的MK型單向節(jié)流閥即爲(wèi)此結(jié)構(gòu)。
管式單向節(jié)流閥
單向節(jié)流閥在結(jié)構(gòu)上有兩種,一種是單向閥和節(jié)流閥共用一個閥芯,另一種是單向閥和節(jié)流閥兩個閥芯是分開的。如:中低壓單向節(jié)流閥(LI型),節(jié)流閥與單向閥共用一個閥芯,中高壓單向節(jié)流閥(LDF型)兩個閥芯是分開的,它們的壓力流量系列均同節(jié)流閥。它們的結(jié)構(gòu)見圖3~圖5所示。
