4WRL25W1Z350S-3X/G24Z4/M博世力士乐REXROTH比例阀

阀对流量的控制可以分为两种：

一种是开关控制：要么全开、要么全关，流量要么大、要么小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。

另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。

所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。

比例阀也分为压力阀、流量阀和方向阀几大类。近来又出现了功能复合化的趋势。

 

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。

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。

蝶阀(英文：butterfly valve)是指关闭件(阀瓣或蝶板)为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，在管道上主要起切断和节流作用。蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。蝶阀全开到全关通常是小于90° ，蝶阀和蝶杆本身没有自锁能力，为了蝶板的定位，要在阀杆上加装蜗轮减速器。采用蜗轮减速器，不仅可以使蝶板具有自锁能力，使蝶板停止在任意位置上，还能改善阀门的操作性能。工业专项使用蝶阀的特点：能耐高温，适用压力范围也较高，阀门公称通径大，阀体采用碳钢制造，阀板的密封圈采用金属环代替橡胶环。
