REXROTH 0811404820 力士樂比例伺服閥  電液比例閥簡(jiǎn)稱比例閥。普通液壓閥只能通過預(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)較佳控制曲線實(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。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)液壓閥的手動(dòng)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(jiǎn)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(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兩個(gè)工作位置，并且在吸合時(shí)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)主要由較靴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銜鐵10、氣隙和較靴1，形成回路口較靴對(duì)銜鐵產(chǎn)生吸力門在線圈中電流一定時(shí)。吸力的大小因較靴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調(diào)整液壓閥，就能使輸出樂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(dòng)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。近來又出現(xiàn)了功能復(fù)合化的趨勢(shì)。

比例控制閥主要用於開回路控制(open loop cool);比例控制閥的輸出量與輸入信號(hào)成比例關(guān)系，且比例控制閥內(nèi)電磁線圈所產(chǎn)生的磁力大小與電流成正比。

在傳統(tǒng)型式的液壓控制閥中，只能對(duì)液壓進(jìn)行定值控制，例如:壓力閥在某個(gè)設(shè)定壓力下作動(dòng)，流量閥保持通過所設(shè)定的流量，方向閥對(duì)於液流方向通/斷的切換。因此這些控制閥組成的系統(tǒng)功能都受到一些限制，隨著技術(shù)的進(jìn)步，許多液壓系統(tǒng)要求流量和壓力能連續(xù)或按比例地隨控制閥輸入信號(hào)的改變而變化。液壓伺服系統(tǒng)雖能滿足其要求，而且精度很高，但對(duì)於大部分的工業(yè)來說，他們并不要求系統(tǒng)有如此高的品質(zhì)，而希望在保證一定控制性能的條件下，同時(shí)價(jià)格低廉，工作可靠，維護(hù)簡(jiǎn)單，所以比例控制閥就是在這種背景下發(fā)展起來的。

比例控制閥可分為壓力控制閥，流量控制及方向控制閥三類。

壓力控制閥:用比例電磁閥取代引導(dǎo)式溢流閥的手調(diào)裝置便成為引導(dǎo)式比例溢流閥，其輸出的液壓壓力由輸入信號(hào)連續(xù)或按比例控制。

流量控制閥:用比例電磁閥取代節(jié)流閥或調(diào)速閥的手調(diào)裝置而以輸入信號(hào)控制節(jié)流閥或調(diào)速閥之節(jié)流口開度，可連續(xù)或按比例地控制其輸出流量。故節(jié)流口的開度便可由輸入信號(hào)的電壓大小決定。

方向控制閥:比例電磁閥取代方向閥的一般電磁閥構(gòu)成直動(dòng)式比例方向閥，其滑軸不但可以換位，而且換位的行程可以連續(xù)或按比例地變化，因而連通油口間的通油面積也可以連續(xù)或按比例地變化，所以比例方向控制閥不但能控制執(zhí)行元件的運(yùn)動(dòng)方向外，還能控制其速度。
