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。

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。

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。

 功能、组成部分： 阀芯机能 E. 和 W.

4WRLE 型比例阀是一个带电气位置反馈和集成电子元件 (OBE)

的先导式比例方向控制阀。

装配

阀的基本构成包括 3 个主要组件：

? 先导控制阀 (1) 包含控制阀芯和套筒、复位弹簧、控制线圈

和感应式位置传感器（可选配电子元件保护膜 (5) 和减振板

(4)）

? 带对中弹簧和位置反馈的主阀 (2)

? 带模拟量 (6) 或 IO-Link 接口的集成电子元件 (OBE) (3)

功能

当集成电子元件 (OBE) 处于被关闭或未激活的状态时，先导控

制阀的控制阀芯在弹簧作用下处于 "故障安全" 位置。主阀的控

制阀芯位于其弹簧对中中心位置。

集成电子元件 (OBE) 将****控制值与主阀控制阀芯的位置实际

值进行比较。在有控制偏差的情况下，将激活控制线圈。由于磁

力发生改变，先导控制阀芯进行调节以抵住弹簧。

通过改变控制截面大小而产生的流量可以对主控制阀芯进行调

节。主控制阀芯的行程/控制截面与控制值成比例进行调节。

先导油可通过油口 P 从内部供给先导控制阀，也可通过油口 X

从外部供给先导控制阀。可通过油口 T 从内部实现到油箱的反

馈，也可以通过油口 Y 从外部实现。

控制线圈切断

在以下故障情况下，集成电子元件 (OBE) 使控制线圈断电，先

导控制阀芯将设置为 "故障安全" 位置，并将卸载主阀的先导油

腔。通过弹簧操作，主阀控制阀芯将移动至中心位置。

? 低于较小电源电压

? 仅在当接口为 "F1" 时：

– 值低于较小电流控制值 2 mA（包括控制值线的电缆中断

（电流环））。

? 仅当接口为 "L1" 时：

– 使能未激活，通讯中断（看门狗）

– 内部 IO-Link 发生故障时

? 仅当接口为 "C6" 时：

– 额外的，释放未激活

减振板 "D"

减振板 (4) 降低集成电子元件上的加速振幅（频率 >300 Hz）。

注意：

对于主要为低激励频率 (<300 Hz) 的应用，不建议使用减振

板。

减压阀可将阀前管路较高的液体压力减少至阀后管路所需的水平。这里的传输介质主要是水。减压阀广泛用于高层建筑、城市给水管网水压过高的区域、矿井及其他场合，以保证给水系统中各用水点获得适当的服务水压和流量。鉴于水的漏失率和浪费程度几乎同给水系统的水压大小成正比，因此减压阀具有改善系统运行工况和潜在节水作用，据统计其节水效果约为30%。
