结构原理

1）MK型单向节流阀 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型准确节流阀 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。

力士乐REXROTH叠加式液控单向阀Z2S 6

二通插装阀与普通液压阀的功能相同，都是用来控制液压系统工作介质的压力、流量和流动方向的。二通插装阀由插入元件、先导元件、控制盖板和插装块体四部分组成。插入元件主要由阀芯、阀套、弹簧和密封件组成，图1为其示意图。控制盖板上,根据插装阀的不同控制功能，安装有相应的先导控制级元件，以实现对液压系统压力、流量和方向的控制,插装块体则既是嵌入插入元件及安装控制盖板的基础阀体，又是主油路和控制油路的通道体。
