电液比例阀简称比例阀。普通液压阀只能通过预调的方式对液流的压力、流量进行定值控制。但是当设备机构在工作过程中要求对液压系统的压力、流量参数进行调节或连续控制，例如.要求工作台在工作进给时按慢、快、慢连续变化的速度实现进给，或按一定精度模拟某个控制曲线实现旅力控制.普通液压阀则实现不了。这时可以用电液比例阀对液压系统进行控制。

比例溢流阀

1)比例环节

比例环节也称为无惯性环节,对液压缸或马达，忽略液压油的可压缩性和泄漏,液压缸的流量Q= VA。其中V为活塞速度;A为活塞面积。其传递函数为: g(s)= V (s)/Q(s)= 1/A =式中K为比例环节放大系数或增益,表示输入量经过放大K倍后输出。

(2)比例控制系统

比例控制系统根据有无反馈分为开环控制和闭环控制。如比例阀控制液压缸或马达系统可以实现速度位移转速和转矩等的控制。

由于开环控制系统的精度比较低,无级调节系统输入量就可以无级调节系统输出量力速度以及加减速度等。这种控制系统的结构组成简单,系统的输出端和输入端不存在反馈回路,系统输出量对系统输入控制作用没有影响,没有自动纠正偏差的能力,其控制精度主要取决于关键元器件的特性和系统调整精度，所以只能应用在精度要求不高并且不存在内外干扰的场合。开环控制系统一.般不存在所谓稳定性问题。

闭环控制系统(即反馈控制系统)的优点是对内部和外部干扰不敏感，系统工作原理是反馈控制原理或按偏差调整原理。这种控制系统有通

过负反馈控制自动纠正偏差的能力。但反馈带来了系统的稳定性问题，只要系统稳定，闭环控制系统可以保持较高的精度。因此, 目前普遍采用闭环控制系统。

力士乐REXROTH比例减压阀，先导操作DBEM

流量阀是由一个手动调节阀组和一个自动平衡阀组组成。调节阀组作用是设定流量，自动平衡阀组作用是维持流量恒定。系统流体的工作压力为P1，手动调节阀的前后压力分别为P2、P3。当手动调节阀调到某一位置时，即人为确定了“设定流量”Kv即手动调节阀的流量系数，流量G=Kv（P2-P3），Kv为，Kv设定后，只要P2－P3不变，则流量G不变。当系统流量加大时，(P2—P3)的实际值超过了允许的给定值，此时通过感压膜和弹簧作用使自动调节阀组自动关小，直至流量重新维持到设定流量，反之亦然。
