液控單向閥是依靠控制流體壓力，可以使單向閥反向流通的閥。這種閥在煤礦機械的液壓支護設備中占有較重要的地位。液控單向閥與普通單向閥不同之處是

多了一個控制油路K，當控制油路未接通壓力油液時，液控單向閥就象普通單向閥一樣工作，壓力油只從進油口流向出油口，不能反向流動。當控制油路油控

制壓力輸入時，活塞頂桿在壓力油作用下向右移動，用頂桿頂開單向閥，使進出油口接通。若出油口大于進油口就能使油液反向流動。

(1)保持壓力。
滑閥式換向閥都有間隙泄漏現象，只能短時間保壓。當有保壓要求時，可在油路上加一個液控單向閥，利用錐閥關閉的嚴密性，使油路長時間保壓。
(2)液壓缸的“支承”。
在立式液壓缸中，由于滑閥和管的泄漏，在活塞和活塞桿的重力下，可能引起活塞和活塞桿下滑。將液控單向閥接于液壓缸下腔的油路，則可防止液壓缸活塞和滑塊等活動部分下滑。
(3)實現液壓缸鎖緊。
當換向閥處于中位時，兩個液控單向閥關閉，可嚴密封閉液壓缸兩腔的油液，這時活塞就不能因外力作用而產生移動。
(4)大流量排油。
液壓缸兩腔的有效工作面積相差很大。在活塞退回時，液壓缸右腔排油量驟然增大，此時若采用小流量的滑閥，會產生節流作用，限制活塞的后退速度；若加設液控單向閥，在液壓缸活塞后退時，控制壓力油將液控單向閥打開，便可以順利地將右腔油液排出。
(5)作充油閥。
立式液壓缸的活塞在高速下降過程中，因高壓油和自重的作用，致使下降迅速，產生吸空和負壓，必須增設補油裝置。液控單向閥作為充油閥使用，以完成補油功能。
(6)組合成換向閥。
在設計液壓回路時，有時可將液控單向閥組合成換向閥使用。例如：用兩個液控單向閥和一個單向閥并聯（單向閥居中），則相當于一個三位三通換向閥的換向回路。需要指出，控制壓力油油口不工作時，應使其通回油箱，否則控制活塞難以復位，單向閥反向不能截止液流。
