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。应用广泛的比例电磁铁是耐高压直流比例电磁铁。

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。应用广泛的比例电磁铁是耐高压直流比例电磁铁。

力士乐REXROTH二位二通比例换向阀，直接操作（高性能）KKDSR1

博世力士乐（BOSCH-REXROTH）比例阀，比例溢流阀，比例溢流阀，电液比例阀，比例换向阀，比例控制阀：

 

液压阀的分类:

1根据结构形式分类

滑阀：滑阀为间隙密封，阀芯与阀口存在一定的密封长度，因此滑阀运动存在一个死区。

锥阀：锥阀阀芯半锥角一 般为12?-20?，阀口关闭时为线密封，密封性能好且动作灵敏。

球阀：性能与锥阀相同

2.根据控制制方式不同分:

定值或开关控制阀:被控制量为定值的阀类，包括普通控制阀、插装阀、叠加阀。

比例控制阀:被控制量与输入信号成比例连续变化的阀类，包括普通比例阀和带内反馈的电液比例阀。

伺服控制阀:被控制量与(输出与输入之间的)偏差信号成比例连续变化的阀类，包括机液伺服阀和电液伺服阀。.

数字控制阀:用数字信息直接控制阀口的启闭，来控制液流的压力、流

量、方向的阀类。

3.根据用途分:

压力控制阀、流量控制阀、方向控制阀

方向控制阀的作用:在液压系统中控制液流方向。

方向控制阀包括:单向阀和换向阀

单向阀包括:普通单向阀和液控单向阀

1.普通单向阀

使油液只能沿一个方向流动，反向则被截止的方向阀。

普通单向阀的应用

常被安装在泵的出口，一方面防止压力冲击影响泵的正常工作，另一方面防止泵不工作时系统油液倒流经泵回油箱。

被用来分隔油路以防止高低压干扰。:

与其他的阀组成单向节流阀、单向减压阀、单向顺序阀等复合阀。

安装在执行元件的回油路上，使回油具有一定背压。作背压阀的单向阀应更换刚度的弹簧，其正向开启压力为( 0. 3~0.5) MPa。

2.液控单向阀

外泄式液控单向阀，内泄式单向阀

工作原理:当控制油口不通压力油时，油液只能从pi→P:当控制油口通压力油时，正、反向的油液均可自由通过。

3.换向阀

换向阀是利用阀芯在阀体孔内作相对运动，使油路接通或切断而改变油流方向的阀。

换向阀的分类

按结构形式可分:滑阀式、转阀式、球阀式。

按阀体连通的主油路数可分:两通、三通、四通...等。

按阀芯在阀体内的工作位置可分:两位、三位、四位等。

按操作阀芯运动的方式可分:手动、机动、电磁动、液动、电液动等。

换向阀的中位机能，多位阀在不同工作位置时，各油口的连通方式体现了换向阀的不同的控制机能，称之为换向阀的机能。对于三位阀，左、右位实现执行元件的换向，中位则能满足执行元件处于非工作状态时系统的不同要求。
