電液比例閥簡(jiǎn)稱(chēng)比例閥。普通液壓閥只能通過(guò)預(yù)調(diào)的方式對(duì)液流的壓力、流量進(jìn)行定值控制。但是當(dāng)設(shè)備機(jī)構(gòu)在工作過(guò)程中要求對(duì)液壓系統(tǒng)的壓力、流量參數(shù)進(jìn)行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺(tái)在工作進(jìn)給時(shí)按慢、快、慢連續(xù)變化的速度實(shí)現(xiàn)進(jìn)給，或按一定精度模擬某個(gè)*控制曲線實(shí)現(xiàn)旅力控制.普通液壓閥則實(shí)現(xiàn)不了。這時(shí)可以用電液比例閥對(duì)液壓系統(tǒng)進(jìn)行控制。
電液比例閥是一種按輸入的電信號(hào)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(lèi)。它山電-機(jī)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(hào)連續(xù)地按比例地轉(zhuǎn)換為機(jī)械力和位移輸出，后者在接受這種機(jī)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(gè)途徑一是用比例電磁鐵取代傳統(tǒng)液壓閥的手鑫調(diào)節(jié)裝置或取代普通電磁鐵發(fā)展起來(lái)的;二是由電液伺服閥簡(jiǎn)化結(jié)構(gòu)、降低精度發(fā)展起來(lái)的。下面介紹的比例閥均指前者，它是當(dāng)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(kāi)兩個(gè)工作位置，并且在吸合時(shí)磁路中幾乎沒(méi)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(chǎng)，因隔磁環(huán)4的存在。使磁力線主要部分通過(guò)銜鐵10、氣隙和極靴1，形成回路口極靴對(duì)銜鐵產(chǎn)生吸力門(mén)在線圈中電流一定時(shí)。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(jì)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(lái)調(diào)整液壓閥，就能使輸出樂(lè)力或流量與輸人電流對(duì)應(yīng)成比例地發(fā)生變化。
比例閥用于模擬控制，是介于普通開(kāi)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)備自鑫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(diǎn)是①能簡(jiǎn)單地實(shí)現(xiàn)遠(yuǎn)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(shí)現(xiàn)對(duì)執(zhí)行機(jī)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(shí)的沖擊;③油路簡(jiǎn)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(chǎng)合。
比例閥也分為壓力閥、流量閥和方向閥幾大類(lèi)。近來(lái)又出現(xiàn)了功能復(fù)合化的趨勢(shì)。 經(jīng)銷(xiāo)品牌：BOSCH-REXROTH博士/力士樂(lè)、SUN太陽(yáng)、DENISON丹尼遜、PARKER派克、VICKERS威格士、HAWE哈威、HYDAC賀德克、ATOS阿托斯、DANFOSS丹佛斯長(zhǎng)期供應(yīng)力士樂(lè)柱塞泵、換向閥、溢流閥、單向閥、等電磁閥，比例閥，放大器，伺服驅(qū)鑫器，價(jià)格好，貨期短，常見(jiàn)型號(hào)備有大量現(xiàn)貨，選購(gòu)。
