电液比例阀简称比例阀普通液压阀能通预调式液流压力、流量进行定值控制设备机构工作程要求液压系统压力、流量参数进行调节或连续控制例.要求工作台工作进给按慢、快、慢连续变化速度实现进给或按定精度模拟某佳控制曲线实现旅力控制.普通液压阀则实现用电液比例阀液压系统进行控制
电液比例阀种按输入电信号连续、按比例控制液压系统液流向、流量压力阀类山电-机械比例转换装置液压控制阀本体两部构.前者输入电信号连续按比例转换机械力位移输者接受种机械力位移、按比例连续输压力流量.
电液比例阀发展主要两途径用比例电磁铁取代传统液压阀手调节装置或取代普通电磁铁发展起;二由电液伺服阀简化结构、降低精度发展起面介绍比例阀均指前者今比例阀主流与普通液压阀互换
比例电磁阀结构图5-27所示比例电磁铁直流电磁铁与普通直流电磁铁同普通直流电磁铁衔铁吸合断两工作位置并且吸合磁路几乎没气隙.比例电磁铁要求吸合力或位移与给定电流比例并衔铁全部工作行程磁路保持定气隙‘.其结构主要由极靴1、线圈2、壳体5衔铁10等组线圈2通电产磁场隔磁环4存使磁力线主要部通衔铁10、气隙极靴1形路口极靴衔铁产吸力门线圈电流定吸力极靴1与衔铁间距离同变化衔铁气隙适段行程吸力随位置改变发变化
博世力士乐比例伺服阀4WRL25V370M-3X/G24Z4/M
设计使比例电磁铁衔铁段行程工作改变线圈电流即衔铁与其比吸力用比例电磁铁代替螺旋手柄调整液压阀能使输乐力或流量与输电流应比例发变化
比例阀用于模拟控制介于普通关控制与伺服控制间控制式特别适合于
设备革新或改造使设备自化控制水平提高其现代液雌系统占比例口
与普通液压阀相比.比例阀优点:①能简单实现远距离控制:②能连续、按比例控制液压系统压力流量实现执行机构位置、速度力连续控制并能防止或减压力、速度变换冲击;③油路简化元件数量少
比例阀适用于既要求能连续控制胀力、流量.向.需要I控制精度场合
比例阀压力阀、流量阀向阀几类近现功能复合化趋势
