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。
注意事项。
(1)必须保证液控单向阀有足够的控制压力,绝对不允许控制压力失压。应注意控制压力是否满足反向开启的要求。如果液控单向阀的控制引自主系统时,则要分析主系统压力的变化对控制油路压力的影响,以免出现液控单向阀的误动作。
(2)根据液控单向阀在液压系统中的位置或反向出油腔后的液流阻力(背压)大小,合理选择液控单向阀的结构(简式或复式)及泄油方式(内泄或外泄)。对于内泄式液控单向阀来说,当反向油出口压力超过一定值时,液控部分将失去控制作用,故内泄式液控单向阀一般用于反向出油腔无背压或背压较小的场合;而外泄式液控单向阀可用于反向出油腔背压较高的场合,以降低最小的控制压力,节省控制功率。系统若采用内卸式,则柱塞缸将断续下降发出振动和噪声。

节流口堵塞原因:

1、油液中的机械杂质或因氧化析出的胶质、沥青、碳渣等污物堆积在节流缝隙处。

2、由于油液老化或受到挤压后产生带电的极化分子,而节流缝隙的金属表面上存在电位差,故极化分子被吸附到缝隙表面,形成牢固的边界吸附层,吸附层厚度一般为5~8微米,因而影响了节流缝隙的大小。以上堆积、吸附物增长到一定厚度时,会被液流冲刷掉,随后又重新附在阀口上。这样周而复始,就形成了流量的脉动。

3、阀口压差较大时,因阀口温度高,液体受挤压的程度增强,金属表面也更易受摩擦作用而形成电位差,因此压差大时容易产生堵塞现象。

减轻节流口堵塞的措施:

1、选择水力半径大的薄刃节流口。

2、精密过滤并定期更换油液。

3、适当减小节流口前后的压差。

4、采用电位差较小的金属材料、选用抗氧化稳定性好的油液、减小节流口表面粗糙度。
