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。

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。

三位四通方向阀

4WRPE 型阀门是带有电气位置反馈和集成电子元件 (OBE) 的直动式方向控制阀。

结构

阀门的基本构成包括：

阀体 (1)

带有压缩弹簧（3.1 和 3.2）的控制阀芯 (2)

带位置传感器 (4) 的控制线圈（可选配电子元件保护膜 (8)）

行程线圈 (7)

带模拟接口 (6) 或 IO-Link 接口的集成电子元件 (OBE) (5)（可选配衰减阀板 (9)）

功能

集成电子元件 (OBE) 将指定控制值与实际位置值进行比较。在有控制偏差的情况下，将激活相关线圈。由于磁力发生改变，控制阀芯 (2) 将扺住相应弹簧进行调节。行程/控制阀芯剖面以与控制值成比例的方式进行控制。在控制值预设值为 0 V 的情况下，电子元件将控制阀芯 (2) 调节到中心位置。

错误检测

如果出现以下错误情况，电子元件将使控制线圈断电：

低于较小电源电压 ≤ 15 V（重新启动 ≥ 17.5 V）。

仅在接口 "F1" 处：

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））。

仅在接口 "L1" 处：

使能未激活，通讯中断（看门狗）

内部 IO-Link 发生故障时

仅在接口 "C6" 处：

额外使能未激活

控制阀芯 (2) 在压缩弹簧（3.1 和 3.2）的作用下保持在机械中心位置（（带有符号 V）不适用于液压中心位置）。

衰减阀板 "D"

衰减阀板 (9) 降低加速振幅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，不建议使用衰减阀板。

电子元件保护膜“-967”

要保护集成电子元件 (OBE) 壳体中的冷凝格式，可以使用电子元件保护膜 (8)。

建议用于空气湿度高且周期温度变化明显的外部工业标准条件（例如室外）。

力士乐REXROTH高响应的换向阀，直接操作，集成的数字轴控制器（IAC多以太网）4WRPDH

调速阀是进行了压力补偿的节流阀。它由定差减压阀和节流阀串联而成。节流阀前、后的压力分别引到减压阀阀芯右、左两端，当负载压力加大，于是作用在减压阀芯左端的液压力加大，阀芯右移，减压口加大，压降减小，使也加大，从而使节流阀的压差保持不变；反之亦然。这样就使调速阀的流量恒定不变。在载荷压力变化时能保持节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。
