廣泛應用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

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(shè)備機構(gòu)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(gòu)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(jié)構(gòu)、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(jié)構(gòu)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(jié)構(gòu)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(shè)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(guān)控制與伺服控制之間的控制方式，它也特別適合于

設(shè)備的革新或改造。使設(shè)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(gòu)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。

一種液壓壓力控制閥。在液壓設(shè)備中主要起定壓溢流作用，穩(wěn)壓，系統(tǒng)卸荷和安全保護作用。定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當系統(tǒng)壓力增大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。
?　　穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓運動部件平穩(wěn)性增加。
?　　系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。
?　　安全保護作用：系統(tǒng)正常工作時，閥門關(guān)閉。只有負載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進行過載保護，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)最高工作壓力高10%～20%）。
?　　實際應用中一般有：作卸荷閥用，作遠程調(diào)壓閥，作高低壓多級控制閥，作順序閥，用于產(chǎn)生背壓（串在回油路上）。
?　　溢流閥一般有兩種結(jié)構(gòu)：1、直動型溢流閥 。2、先導型溢流閥。
?　　對溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。
