電液比例閥簡稱比例閥。普通液壓閥只能通過預調(diào)的方式對液流的壓力、流量進行定值控制。但是當設備機構在工作過程中要求對液壓系統(tǒng)的壓力、流量參數(shù)進行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺在工作進給時按慢、快、慢連續(xù)變化的速度實現(xiàn)進給，或按一定精度模擬某個最佳控制曲線實現(xiàn)旅力控制.普通液壓閥則實現(xiàn)不了。這時可以用電液比例閥對液壓系統(tǒng)進行控制。
電液比例閥是一種按輸入的電信號連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。它山電-機械比例轉(zhuǎn)換裝置和液壓控制閥本體兩大部分構成.前者將輸入的電信號連續(xù)地按比例地轉(zhuǎn)換為機械力和位移輸出，后者在接受這種機械力和位移之后、按比例連續(xù)地輸出壓力和流量.
電液比例閥的發(fā)展主要有兩個途徑一是用比例電磁鐵取代傳統(tǒng)液壓閥的手動調(diào)節(jié)裝置或取代普通電磁鐵發(fā)展起來的;二是由電液伺服閥簡化結構、降低精度發(fā)展起來的。下面介紹的比例閥均指前者，它是當今比例閥的主流。與普通液壓閥可以互換。
比例電磁閥的結構如圖5-27所示。比例電磁鐵是直流電磁鐵，但它與普通直流電磁鐵不同。普通直流電磁鐵的銜鐵只有吸合和斷開兩個工作位置，并且在吸合時磁路中幾乎沒有氣隙.而比例電磁鐵要求吸合力或位移與給定電流成比例。并在銜鐵的全部工作行程上，磁路中保持一定的氣隙‘.其結構主要由極靴1、線圈2、殼體5和銜鐵10等組成。線圈2中通電后產(chǎn)生磁場，因隔磁環(huán)4的存在。使磁力線主要部分通過銜鐵10、氣隙和極靴1，形成回路口極靴對銜鐵產(chǎn)生吸力門在線圈中電流一定時。吸力的大小因極靴1與銜鐵間的距離不同而變化。但銜鐵在氣隙適中的一段行程中，吸力隨位置的改變發(fā)生的變化很小。
設計中就使比例電磁鐵的銜鐵在這段行程中工作。因此。改變線圈中的電流，即可在銜鐵上得到與其成正比的吸力。用比例電磁鐵代替螺旋手柄來調(diào)整液壓閥，就能使輸出樂力或流量與輸人電流對應成比例地發(fā)生變化。
比例閥用于模擬控制，是介于普通開關控制與伺服控制之間的控制方式，它也特別適合于
設備的革新或改造。使設備自動化控制水平大為提高。其在現(xiàn)代液雌系統(tǒng)中占比例很大口
與普通液壓閥相比.比例閥的優(yōu)點是:①能簡單地實現(xiàn)遠距離控制:②能連續(xù)地、按比例地控制液壓系統(tǒng)的壓力和流量。從而實現(xiàn)對執(zhí)行機構的位置、速度和力的連續(xù)控制，并能防止或減小壓力、速度變換時的沖擊;③油路簡化，元件數(shù)量少。
比例閥適用于既要求能連續(xù)控制脹力、流量.和方向.而又不需要很I的控制精度的場合。
比例閥也分為壓力閥、流量閥和方向閥幾大類。近來又出現(xiàn)了功能復合化的趨勢。
