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。

节流阀和单向节流阀是简易的流量控制阀，它们在定量泵液压系统中的主要作用是与溢流阀配合，组成三种节流调速系统：即进油节流调速系统、回油节流调速系统和旁路节流调速系统。对于执行元件要求往返节流调速的系统可使用两个单向节流阀。节流阀也在容积节流调速回路中使用。这种阀没有压力及温度补偿装置，不能自动补偿载荷及油液粘度变化时造成的速度不稳定，但其结构简单，制造和维护方便。所以在载荷变化不大或对速度稳定性要求不高的一般液压系统中得到广泛应用。

直行程阀阀芯是垂直节流，而介质是水平流进流出，阀腔内流道必然转弯倒拐，使阀的流路变得相当复杂(形状如倒“S”型)。这样，存在许多死区，为介质的沉淀提供了空间，长此以往，造成堵塞。角行程阀节流的方向就是水平方向，介质水平流进，水平流出，容易把不干净介质带走，同时流路简单，介质沉淀的空间也很少，所以角行程阀防堵性能好。

力士乐REXROTH方向阀

力士乐REXROTH二位四通和三位四通方向阀Z4WE 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。
