比例溢流阀

1)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。

(2)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。

电液比例阀是一种按输入的电信号连续地、按比例地控制液压系统的液流方向、流量和压力的阀类。它由机械比例转换装置和液压控制阀本体两大部分构成.前者将输入的电信号连续地按比例地转换为机械力和位移输出，后者在接受这种机械力和位移之后、按比例连续地输出压力和流量.

电液比例阀的发展主要有两个途径一是用比例电磁铁取代传统液压阀的手动调节装置或取代普通电磁铁发展起来的;二是由电液伺服阀简化结构、降低精度发展起来的。下面介绍的比例阀均指前者，它是当今比例阀的主流。与普通液压阀可以互换。

类型

4WREE 10 W75-2X/G24K31/A1M

材料编号

R901446211

4/2 和 4/3 比例换向阀，直动式，带电气位置反馈，带集成电子元件 (OBE)

4WREE

尺寸 6、10

组件系列 2X

较大工作压力 315 bar

较大流量 180 l/min

类型 4WREE...-2X/...

4/2 和 4/3 比例方向阀设计为板式设计的直接操作装置。通过带中心螺纹和可拆卸线圈的比例电磁铁进行操作。螺线管通过集成电子设备进行控制。

设置：

阀门主要包括：

外壳 (1) 带连接面

带压缩弹簧（3 和 4）和弹簧板（5 和 6）的控制阀芯 (2)

带中心螺纹的电磁阀（7 和 8）

位置传感器 (9)

集成电子 (13)

电气零点调整 (12)，可通过 Pg7 访问

功能：

对于断电的电磁阀（7 和 8），由于弹簧板（5 和 6）之间的压缩弹簧（3 和 4），控制阀芯（2）的中心位置

通过一个比例电磁阀的控制直接驱动控制阀芯 (2)，例如。G。电磁阀“b” (8)

→ 控制阀芯 (2) 与电气输入信号成比例地向左移动

→ P 到 A 和 B 到 T 的连接通过渐进式节流孔型横截面

流动特性

关闭电磁阀 (8)

→ 控制阀芯 (2) 通过压缩弹簧 (3) 返回到中心位置

在断电状态下，控制阀芯 (2) 被螺线管的复位弹簧保持在机械中心位置。对于控制阀芯符号“V”，该位置不对应液压中心位置！当电动阀控制回路关闭时，控制阀芯位于液压中心位置。

重要通知：

PG 接头 (11) 不得打开。禁止对位于下方的调节螺母进行机械调节，否则会损坏阀门！

带有两个阀芯位置的阀门：（4WREE...A... 型）

该阀门版本的功能基本上对应于具有三个阀芯位置的阀门。但是，2 阀芯位置阀仅配备电磁阀“a” (7)。安装了一个塞螺钉 (10)，而不是第二个比例电磁阀。

注意：

由于设计原理，在生命周期内可能增加的内部泄漏是阀门固有的。

注意：

不得让油箱管路空转。在相应的安装条件下，必须安装一个预紧阀（预紧压力约 2 bar）。

顺序阀

顺序阀是一种利用压力控制阀口通断的压力阀。

按控制油来源不同分内控和外控，按弹簧腔泄漏油引出方式不同分内泄和外泄。

顺序阀的四种控制方式

通过改变上盖或底盖的装配位置可得到内控外泄、内控内泄、外控外泄、外控内泄四种类型。

内控外泄顺序阀

内控外泄顺序阀与溢流阀非常相象:阀口常闭，进口压力控制，但是该

阀出口油液要去工作，所以有单独的泄油口。

内控外泄顺序阀用于多个执行元件顺序动作。其进口压力先要达到阀的调定压力，而出口压力取决于负载。当负载压力高于阀的调定压力时，进口压力等于出口压力，阀口全开;当负载压力低于调定压力时，进口压力等于调定压力，阀的开口一定。
