放大器是一种适合于开环比例阀的电子控制单元，导轨安装式，该控制器输出电流与参考信号成比例，而与温度变化及负载阻抗无关。比例电磁铁采用PWM电源，可以减小阀的磁性滞环，提高控制精度。前面板上，装有用于参数设定的调整电位计，用于改善系统性能。该放大器有三种型号，分别用于单电磁铁比例阀、双电磁铁比例阀和有双通道控制的单电磁铁比例阀。每种型号的电子控制单元的大电流和开关频率（PWM）互不相同，可根据使用阀的型号进行选择（PWM）。

 

电液比例阀是比例控制系统中的主要功率放大元件,按输入电信号指令连续地成比例地控制液压系统的压办流量等参数。与伺服控制系统中的伺服阀相比,在某些方面还有一定的性能差距(主要性能比较如表1所示),但它显著的优点是抗污染能力强,大大地减少了由污染而造成的工作故障,提高了液压系统的工作稳定性和可靠性。另一方面比例阀的成本比伺服阀低，结构也简单,已在许多场合获得广泛应用。

 

比例阀按功能分为三大类

(1)比例压力阀。有溢流阀减压阀,分别有直动和先导两种结构;可连续地或按比例地远程控制其输出油液压力;

(2)比例换向阀。有直动和先导两种结构,直动阀有带位移传感器和不带位移传感器两类。由于使用了比例电磁铁阀芯不仅可以换位，而且换位的行程可以连续地或按比例地变化。因而连通油口间的通流面积也可以连续或按比例地变化。所以比例换向阀不仅能够控制执行元件的方向而且能够控制其速度。因为这个原因比例阀中的比例换向阀应用也普遍;

(3)比例流量阀。有比例调速阀和比例溢流流量控制阀,可连续地或按比例地远程控制其输出流量。

比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。比例电磁铁的结构，它由线圈、衔铁推杆等组成,当有信号输入线圈时,线圈内磁场对衔铁产生作用力,衔铁在磁场中按信号电流的大小和方向成比例连续地运动,再通过固连在一起的销钉带动推杆运动,从而控制滑阀阀芯的运动。应用的比例电磁铁是耐高压直流比例电磁铁。

 

比例电磁铁的类型按照工作原理主要分为

如下几类:

(1)力控制型

这类电磁铁的行程短，只有1 5mm,输出力与输入电流成正比,常用在比例阀的先导控制级

上:

(2)行程控制型

由力控制型加负载弹簧共同组成，电磁铁输出的力通过弹簧转换成输出位移,输出位移与输入电流成正比，工作行程达3mm,线性好，可以用在直控式比例阀上;

(3)位置调节型

衔铁的位置由传感器检测后,发出一个阀内反馈信号,在阀内进行比较后重新调节衔铁的位置。阀内形成闭环控制,精度高,衔铁的位置与力

无关，精度高的比例阀如德国的博世意大利的阿托斯等都采用这种结构。

比例阀与放大器配套使用放大器采用电流负反馈,设置斜坡信号发生器阶跃函数发生器、PD调节器反向器等,控制升压降压时间或运动加速度及减速度。断电时, 能使阀芯处于安全位置。

比例电磁铁和液压阀组成电液比例阀。由于比例电磁铁可以在不同的电流下得到不同的力(或行程),因此可以无级改变压力、流量。故比例电磁铁是比例阀的关键元件。
