單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動,或者用于氣動系統(tǒng)中防止壓縮空氣逆向流動。
單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥,它與單向閥相同,用以防止油液反向流動。但在液壓回路中需要油流反向流動時又可利用控制油壓,打開單向閥,使油流在兩個方向都可流動。液控單向閥采用錐形閥芯,因此密封性能好。在要求封閉油路時,可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無背壓的油路中可用內(nèi)泄式;否則需用外泄式,以降低控制油壓力。
注意事項(xiàng)。
(1)必須保證液控單向閥有足夠的控制壓力,絕對不允許控制壓力失壓。應(yīng)注意控制壓力是否滿足反向開啟的要求。如果液控單向閥的控制引自主系統(tǒng)時,則要分析主系統(tǒng)壓力的變化對控制油路壓力的影響,以免出現(xiàn)液控單向閥的誤動作。
(2)根據(jù)液控單向閥在液壓系統(tǒng)中的位置或反向出油腔后的液流阻力(背壓)大小,合理選擇液控單向閥的結(jié)構(gòu)(簡式或復(fù)式)及泄油方式(內(nèi)泄或外泄)。對于內(nèi)泄式液控單向閥來說,當(dāng)反向油出口壓力超過一定值時,液控部分將失去控制作用,故內(nèi)泄式液控單向閥一般用于反向出油腔無背壓或背壓較小的場合;而外泄式液控單向閥可用于反向出油腔背壓較高的場合,以降低最小的控制壓力,節(jié)省控制功率。系統(tǒng)若采用內(nèi)卸式,則柱塞缸將斷續(xù)下降發(fā)出振動和噪聲。

節(jié)流口堵塞原因:

1、油液中的機(jī)械雜質(zhì)或因氧化析出的膠質(zhì)、瀝青、碳渣等污物堆積在節(jié)流縫隙處。

2、由于油液老化或受到擠壓后產(chǎn)生帶電的極化分子,而節(jié)流縫隙的金屬表面上存在電位差,故極化分子被吸附到縫隙表面,形成牢固的邊界吸附層,吸附層厚度一般為5~8微米,因而影響了節(jié)流縫隙的大小。以上堆積、吸附物增長到一定厚度時,會被液流沖刷掉,隨后又重新附在閥口上。這樣周而復(fù)始,就形成了流量的脈動。

3、閥口壓差較大時,因閥口溫度高,液體受擠壓的程度增強(qiáng),金屬表面也更易受摩擦作用而形成電位差,因此壓差大時容易產(chǎn)生堵塞現(xiàn)象。

減輕節(jié)流口堵塞的措施:

1、選擇水力半徑大的薄刃節(jié)流口。

2、精密過濾并定期更換油液。

3、適當(dāng)減小節(jié)流口前后的壓差。

4、采用電位差較小的金屬材料、選用抗氧化穩(wěn)定性好的油液、減小節(jié)流口表面粗糙度。
