节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，一般仅用于负载变化不大或对速度稳定性要求不高的场合。

 

单向节流阀的结构原理。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，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。

精密节流阀的结构原理。该阀主要由阀体，调节件和节流套组成。在节流口处实现对从A到B的流动的节流。转动节流杆，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。

REXROTH节流阀Z2FS6A2-4X/2QV


对节流阀的性能要求是：
·流量调节范围大，流量一压差变化平滑；
·内泄漏量小，若有外泄漏油口，外泄漏量也要小；
·调节力矩小，动作灵敏。
节流阀(throttle valve)的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降*的情况下作降低介质压力之用。
介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓汽蚀现象。为了尽量减少汽蚀影响，阀瓣采用耐汽蚀材料（合金钢制造）并制成顶尖角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。

节流阀特点
1、构造较简单，便于制造和维修，成本低。
2、调节精度不高，不能作调节使用。
3、密封面易冲蚀，不能作切断介质用。
4、密封性较差。
节流阀按通道方式可分为直通式和角式两种；按启闭件的形状分，有针形、沟形和窗形三种。节流阀的安装与维护应注意以下事项：
该阀经常需要操作，因此应安装在易于方面便操作的位置上。
安装时要注意介质方向与阀体所标箭头方向保持一致。

由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。
对于执行元件负载变化大及对速度稳定性要求高的节流调速系统，必须对节流阀进行压力补偿来保持节流阀前后压差不变，从而达到流量稳定。
