SV10PA1-4X/力士乐液控单向阀
单向阀 Check Valve
单向阀又称止回阀或逆止阀。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。

（1）结构原理
1）MK型单向节流阀 图27是MK型单向节流阀的结构原理图。该阀是管式联接的单向节流阀，其节流口采用轴向三角槽式结构。旋转调节螺母3，可改变节流口通流面积的大小，以调节流量。正向流动时起节流阀作用；反向流动时起单向阀作用，这时由于有部分油液可在环形缝隙中流动，可以清除节流口上的沉积物。在阀体2左端有刻度槽，调节螺母3上有刻度，用以标志调节流量的大小。
2）F型精密节流阀 图28是F型精密节流阀的结构原理图。该阀主要由阀体1，调节件2和节流套3组成。在节流口4处实现对从A到B的流动的节流。转动节流杆5，可调节节流断面。由于节流口制成薄壁孔，故节流不易受温度的影响。

单向节流阀的故障原理
摘要:单向节流阀由单向阀与节流阀并联而成，用于一个方向需要控制流量而另一方向（反向）则油流需要畅通的回路中，以实现执行元件正向可调速，而方向能快速退回。
一、简介
单向节流阀由单向阀与节流阀并联而成，用于一个方向需要控制流量而另一方向（反向）则油流需要畅通的回路中，以实现执行元件正向可调速，而方向能快速退回。
二、故障机理
从单向节流阀的结构可知，单向节流阀的阀芯，正向流动时，起节流阀的作用；反向流动时，起单向阀的作用。有关故障分析可参阅单向阀与节流阀的相关内容进行。
