液控单向阀是依靠控制流体压力,可以使单向阀反向流通的阀。这种阀在煤矿机械的液压支护设备中占有较重要的地位。液控单向阀与普通单向阀不同之处是多了一个控制油路K,当控制油路未接通压力油液时,液控单向阀就象普通单向阀一样工作,压力油只从进油口流向出油口,不能反向流动。当控制油路油控制压力输入时,活塞顶杆在压力油作用下向右移动,用顶杆顶开单向阀,使进出油口接通。若出油口大于进油口就能使油液反向流动。
液控单向阀是方向控制阀中的一种。具体分类:
方向控制阀按其在液压系统中的功能分为单向阀和换向阀两大类。
单向阀在液压传动中有普通单向阀和液控单向阀。
(1)保持压力。
滑阀式换向阀都有间隙泄漏现象,只能短时间保压。当有保压要求时,可在油路上加一个液控单向阀,利用锥阀关闭的严密性,使油路长时间保压。
(2)液压缸的“支承”。
在立式液压缸中,由于滑阀和管的泄漏,在活塞和活塞杆的重力下,可能引起活塞和活塞杆下滑。将液控单向阀接于液压缸下腔的油路,则可防止液压缸活塞和滑块等活动部分下滑。
(3)实现液压缸锁紧。
当换向阀处于中位时,两个液控单向阀关闭,可严密封闭液压缸两腔的油液,这时活塞就不能因外力作用而产生移动。
(4)大流量排油。
液压缸两腔的有效工作面积相差很大。在活塞退回时,液压缸右腔排油量骤然增大,此时若采用小流量的滑阀,会产生节流作用,限制活塞的后退速度;若加设液控单向阀,在液压缸活塞后退时,控制压力油将液控单向阀打开,便可以顺利地将右腔油液排出。
(5)作充油阀。
立式液压缸的活塞在高速下降过程中,因高压油和自重的作用,致使下降迅速,产生吸空和负压,必须增设补油装置。液控单向阀作为充油阀使用,以完成补油功能。
(6)组合成换向阀。
在设计液压回路时,有时可将液控单向阀组合成换向阀使用。例如:用两个液控单向阀和一个单向阀并联(单向阀居中),则相当于一个三位三通换向阀的换向回路。需要指出,控制压力油油口不工作时,应使其通回油箱,否则控制活塞难以复位,单向阀反向不能截止液流。

单向阀Check Valve
单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。
单向阀有直通式和直角式两种。直通式单向阀用螺纹连接安装在管路上。直角式单向阀有螺纹连接、板式连接和法兰连接三种形式。液控单向阀也称闭锁阀或保压阀,它与单向阀相同,用以防止油液反向流动。但在液压回路中需要油流反向流动时又可利用控制油压,打开单向阀,使油流在两个方向都可流动。液控单向阀采用锥形阀芯,因此密封性能好。在要求封闭油路时,可用此阀作为油路的单向锁紧而起保压作用。液控单向阀控制油的泄漏方式有内泄式和外泄式二种。在油流反向出口无背压的油路中可用内泄式;否则需用外泄式,以降低控制油压力。
