功用：正向流通，反向受控流通

结构：普通单向阀+液控装置

工作原理：K不通压力油，工作方式同普通单向阀；K通压力油，阀口打开，可以反向流通

应用：∵液控单向阀具有良好的反密封性

常用于保压、锁紧和平衡回路

图形符号含义：

1、 位——用方格表示，几位即几个方格

2 、通——┴ 、┬ 箭头首尾和堵截符号与一个方格有几个交点即为几通。

3 、油口有固定方位和含义，p——进油口(左下）， T——回油口（右下） ，A.B——与执行元件连接的工作油口（左、右上）。

4 、弹簧——W、M，画在方格两侧

5 、常态位置 ——原理图中，油路应该连接在常态位置。如三位阀在中间一格。

滑阀的中位机能：即滑阀处于常态时的状态，有M型，H型，O型，P型，M型等。

比例阀按功能分为三大类

(1)比例压力阀。有溢流阀减压阀,分别有直动和先导两种结构;可连续地或按比例地远程控制其输出油液压力;

(2)比例换向阀。有直动和先导两种结构,直动阀有带位移传感器和不带位移传感器两类。由于使用了比例电磁铁阀芯不仅可以换位，而且换位的行程可以连续地或按比例地变化。因而连通油口间的通流面积也可以连续或按比例地变化。所以比例换向阀不仅能够控制执行元件的方向而且能够控制其速度。因为这个原因比例阀中的比例换向阀应用也为普遍;

(3)比例流量阀。有比例调速阀和比例溢流流量控制阀,可连续地或按比例地远程控制其输出流量。

比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。比例电磁铁的结构，它由线圈、衔铁推杆等组成,当有信号输入线圈时,线圈内磁场对衔铁产生作用力,衔铁在磁场中按信号电流的大小和方向成比例连续地运动,再通过固连在一起的销钉带动推杆运动,从而控制滑阀阀芯的运动。应用广泛的比例电磁铁是耐高压直流比例电磁铁。

溢流阀是压力控制阀。其作用主要是控制系统压力，以保护油泵和油路系统的安全及保持油路系统的压力恒定。通经为8毫米的溢流阀是一个小型的直接动作的溢流阀，可以和主溢流阀的遥控口连接，对主溢流阀实现远程压力调节。溢流阀的遥控口经换向阀和油箱连接时，可使油路卸荷。此时溢流阀起卸荷作用。溢流阀的遥控口串联换向阀和通经为8毫米的溢流阀时，可实现压力的多级控制。
