电液比例阀是采用了比例控制技术,介于开关型液压阀和电液伺服阀之间的-种液压元件,在工业生产中获得了广泛的应用,输入的电信号有模拟式和数字式两大类,可以用于控制位置(转角)、速度(转速)、加速度(角加速度)、压力(压差)、力(力矩)等参数。电液比例阀等元件可以组成如下三类控制回路和系统
(1)电液比例压力控制回路和系统。例如:用于带钢热连轧机卷取机液压辅助系统的电液比例压力控制回路,用于板带轧机辊缝控制的液压推上系统电液比例压力控制回路,用于带材卷取设备恒张力的闭环电液比例压力控制回路;
(2)电液比例流量控制回路和系统。例如:用于带钢热连轧机精轧机平衡液压系统的电液比例压力控制回路,用于机床微进给的电液比例控制回路,用于旋压机折板机同步的电液比例控制回路,用于电梯的电液比例控制回路;
(3)电液比例多参数控制回路和系统。例如:用于带钢热连轧机精轧换辊液压系统的电液比例压力控制回路,用于液压缸垂直配置而采用wI型阀芯的比例控制回路,用于热轧钢卷步进链式运输机的速度、加减速度控制回路。

电液比例阀是阀内比例电磁铁输入电压信号产生相应动作，使工作阀阀芯产生位移，阀口尺寸发生改变并以此完成与输入电压成比例压力、流量输出元件。阀芯位移也可以以机械、液压或电形式进行反馈。电液比例阀具有形式种类多样、容易组成使用电气及计算机控制各种电液系统、控制精度高、安装使用灵活以及抗污染能力强等多方面优点，应用领域日益拓宽。近年研发生产插装式比例阀和比例多路阀充分考虑到工程机械使用特点，具有先导控制、负载传感和压力补偿等功能。它出现对移动式液压机械整体技术水平提升具有重要意义。特别是电控先导操作、无线遥控和有线遥控操作等方面展现了其良好应用前景。

电液比例阀种类和形式
电液比例阀包括比例流量阀、比例压力阀、比例换向阀。工程机械液压操作特点，以结构形式划分电液比例阀主要有两类:一类是螺旋插装式比例阀，另一类是滑阀式比例阀。
滑阀式比例阀又称分配阀，是移动式机械液压系统基本元件之一，是能实现方向与流量调节复合阀。电液滑阀式比例多路阀是比较理想电液转换控制元件，它保留了手动多路阀基本功能，还增加了位置电反馈比例伺服操作和负载传感等先进控制手段。它是工程机械分配阀更新换代产品。
出于制造成本考虑和工程机械控制精度要求不高特点，--般比例多路阀内不配置位移感应传感器，具有电子检测和纠错功能。，阀芯位移量容易受负载变化引起压力波动影响，操作过程中要靠视觉观察来保证作业完成。电控、遥控操作时更应注意外界千涉影响。近来，电子技术发展，人们越来越多采用内装差动变压器(LDVT)等位移传感器构成阀芯位置移动检测，实现阀芯位移闭环控制。这种由电磁比例阀、位置反馈传感器、驱动放大器和其它电子电路组成高度集成比例阀，具有一定校正功能，可以有效克服一.般比例阀缺点，使控制精度到较大提高。

电液比例多路阀负载传感与压力补偿技术
节约能量、降低油温和提高控制精度，同时也使同步动作几个执行元件运动时互不干扰，现较先进工程机械都采用了负载传感与压力补偿技术。负载传感与压力补偿是一一个很相似概念,都是利用负载变化引起压力变化去调节泵或阀压力与流量以适应系统工作需求。负载传感对定量泵系统来讲是将负载压力负载感应油路引至远程调压溢流阀上，当负载较小时，溢流阀调定压力也较小;负载较大，调定压力也较大，但也始终存一定溢流损失。变量泵系统是将负载传感油路引入到泵变量机构，使泵输出压力随负载压力升高而升高(始终为较小固定压差)，使泵输出流量与系统实际需要流量相等，无溢流损失，实现了节能。压力补偿是提高阀控制性能而采取一种保证措施。将阀口后负载压力引入压力补偿阀，压力补偿阀对阀口前压力进行调整使阀口前后压差为常值，这样节流口流量调节特性流经阀口流量大小就只与该阀口开度有关，而不受负载压力影响。

工程机械电液比例阀先导控制与遥控
电液比例阀和其它专用器件技术进步使工程车辆挡位、转向、制动和工作装置等各种系统电气控制成为现实。一般需要位移输出机构可采用比例伺服控制手动多路阀驱动器完成。电气操作具有响应快、布线灵活、可实现集成控制和与计算机接口容易等优点,现代工程机械液压阀已越来越多采用电控先导控制电液比例阀(或电液开关阀)代替手动直接操作或液压先导控制多路阀。采用电液比例阀(或电液开关阀)另一个显著优点是工程车辆上可以大大减少操作手柄个数，这使驾驶室布置简洁，能够有效降低操作复杂性，对提高作业质量和效率都具有重要实际意义。

四、流量控制阀
流量控制阀用于控制或调节液压系统或回路中工作液体流量大小的阀。如节流阀、调速阀、分集流阀等
大型钢厂现场采用的主要流量控制阀，如：二通流量控制阀、叠加式流量控制阀、双单向节流阀，单向阀、节流阀、液压锁。
1、Z2FS...型双单向节流阀
1.结构分析
Z2FS16型阀是叠加式设计的双路单向节流阀。该阀用于限制来自一个或两个工作油口的主流量或控制流量。
两个对称设置的单向节流阀在一个方向上限定流量,(通过调整节流阀芯),在相反方向上允许自由流通。用于进口节流控制时, 油液从油口A流经节流口( 1 )到达工作油口。节流阀芯( 4.1 )可借助于调节螺钉( 5 )进行轴向调整,从而可以设定节流口(1 )同时,油口A中的油液通经道( 2 )到节流阀芯( 4.1 )的弹簧加载侧(3 )产生的压力与弹簧
共同作用,使节流阀芯( 4.1 )保持在节流位置,
油液从执行器回流推动节流阀芯( 4.2 ),允许油液自由流过。此时阀作为单向阀工作。根据型号(S或S2 ),节流口可以起进口或出口节流的控制作用。限制主流量为了改变执行器的速度(主流量限制),双路单向节流阀是而安装于方向控制阀和底板之间。限制控制流量对液控方向阀,双路单向节流阀用作控制阻尼调节,在此情况下,它被安装于主阀和控制阀之间。

五、比例控制阀
采用比例电磁铁(或力矩马达)将输入信号转换成力或阀的机械位移，使阀的输出(压力、流量)也按照其输入量连续、成比例地进行控制的阀。
大型钢厂现场使用的比例阀主要有下表中的几种:伺服比例控制阀、比例控制阀、电液比例控制阀，比例阀，伺服阀。
1、4WRD E..型比例伺服控制阀(高频响阀)
结构和功能
4WRDE型阀是三级高频响方向阀。该阀可用于开环控制或闭环调节液流的大小和方向，但主要用于闭环调节回路中。
阀主要由下列部分组成:
1.二级先导控制阀由力矩马达( 1 )和由喷嘴挡板阀构成的液压放大器( 5),和用作流量放大级的阀芯衬套组件(6 )(用以控制第三级(7 ))组成。
2.第三级(7)用于流量控制。
3.感应式位移传感器( 8),连接第三级主阀芯( 10)的磁芯(9 )
通过内置电子放大器实现阀闭环控制信号逻辑连接,位置检测系统反馈,和先导阀的控制。
给定值/实际值比较得到的差动电压经过电子控制器放大, 并作为控制偏差量传递到阀的一级。这个信号推动两个控制喷嘴( 3.1, 3.2) 之间的挡板( 2)因而在两个控制腔(11.1.11.2)产生了压差。控制阀芯(4 )因此被推动,并通过相应的液流流到弹簧腔(12.1or12.2)阀芯(10)和带磁芯(9)的位移传感器(8)-直运动,直到实际值和给定值信号再一次相等。在控制条件下;主阀芯( 10 )一直被保持在给定值所对应的位置。
阀芯行程和给定值成正比。通过阀芯( 10 )相对于控制边( 13 )的位置,形成相应的与流量成正比的阀口开度。
阀的动态特性通过电子放大器优化。电子放大器内置于阀上(振荡器,解调器)
零点调节由厂家预先设定,通过闭环控制电子放大器内的电位器, 零点能在名义行程士10%范围内调整。移去阀盖尾部的插头,可以对内置闭环电子放大器进行操作。
