方向控制按用途分为单向阀和换向阀。单向阀:只允许流体在管道中单向接通,反向即切断。换向阀:改变不同管路间的通、断关系。根据阀芯在阀体中的工作位置数分两位、三位等;根据所控制的通道数分两通、三通、四通、五通等;根据阀芯驱动方式分手动,机动,电动,液动等。图2为三位四通换向阀的工作原理。P 为供油口,O 为回油口,A 、B 是通向执行元件的输出口。当阀芯处於中位时,全部油口切断,执行元件不动;当阀芯移到右位时,P 与A 通,B 与O 通;当阀芯移到左位时,P 与B 通,A 与O 通。这样,执行元件就能作正、反向运动。 60年代后期,在上述几种液压控制阀的基础上又研制出电液比例控制阀。它的输出量(压力、流量)能随输入的电信号连续变化。电液比例控制阀按作用不同,相应地分为电液比例压力控制阀﹑电液比例流量控制阀和电液比例方向控制阀等。 压力控制按用途分为溢流阀﹑减压阀和顺序阀。⑴溢流阀:能控制液压系统在达到调定压力时保持恒定状态。用於过载保护的溢流阀称为安全阀。当系统发生故障,压力升高到可能造成破坏的限定值时,阀口会打开而溢流,以保证系统的安全。⑵减压阀:能控制分支回路得到比主回路油压低的稳定压力。减压阀按它所控制的压力功能不同,又可分为定值减压阀(输出压力为恒定值)﹑定差减压阀(输入与输出压力差为定值)和定比减压阀(输入与输出压力间保持一定的比例)。⑶顺序阀:能使一个执行元件(如液压缸﹑液压马达等)动作以后,再按顺序使其他执行元件动作。油泵产生的压力先推动液压缸1运动,同时通过顺序阀的进油口作用在面积A 上,当液压缸1运动完全成后,压力升高,作用在面积A 的向上推力大於弹簧的调定值后,阀芯上升使进油口与出油口相通,使液压缸2运动。

电液系统是一种由电信号处理装置和液压动力机构组成的反馈控制系统。较常见的有电液位置伺服系统、电液速度控制系统和电液力(或力矩)控制系统。是一个典型的电液位置伺服控制系统。图中反馈电位器与指令电位器接成桥式电路。反馈电位器滑臂与控制对象相连,其作用是把控制对象位置的变化转换成电压的变化。反馈电位器与指令电位器滑臂间的电位差(反映控制对象位置与指令位置的偏差)经放大器放大后,加于电液伺服阀转换为液压信号,以推动液压缸活塞,驱动控制对象向消除偏差方向运动。当偏差为零时,停止驱动,因而使控制对象的位置总是按指令电位器给定的规律变化。 电液伺服系统中常用的位置检测元件有自整角机、旋转变压器、感应同步器和差动变压器等。伺服放大器为伺服阀提供所需要的驱动电流。电液伺服阀的作用是将小功率的电信号转换为阀的运动,以控制流向液压动力机构的流量和压力。因此,电液伺服阀既是电液转换元件又是功率放大元件,它的性能对系统的特性影响很大,是电液伺服系统中的关键元件。液压动力机构由液压控制元件、执行机构和控制对象组成。液压控制元件常采用液压控制阀或伺服变量泵。常用的液压执行机构有液压缸和液压马达。液压动力机构的动态特性在很大程度上决定了电液伺服系统的性能。
