液壓系統(tǒng)中的壓力控制閥
在液壓系統(tǒng)中,壓力控制閥可以調(diào)定系統(tǒng)主回路或分支回路的壓力.按照功能分類,常用的壓力控制閥有溢流閥,減壓閥,順序閥和壓力繼電器等.這些壓力控制閥結(jié)構(gòu)上相似,但性能有差別,在系統(tǒng)中的作用也不盡相同.搞清它們的區(qū)別與聯(lián)系,對于學(xué)習(xí)壓力控制回路以至液壓系統(tǒng)的分析廣片常重要的。
一,溢流閥
功能 溢流閥的功能是通過閥口溢流,使被控系統(tǒng)或回路的壓力保持穩(wěn)定,實現(xiàn)穩(wěn)壓,調(diào)壓或限壓的作用.
特點 按照結(jié)構(gòu),溢流閥有直動式和先導(dǎo)式兩種.對于直動式溢流閥,當壓力較高,流量較大時,要求調(diào)壓彈簧有很大的剛度,調(diào)節(jié)性能較差,而滑閥的泄漏也使高壓控制難以實現(xiàn),故只能用于低壓小流量場合.先導(dǎo)式溢流閥的特點是用先導(dǎo)閥控制主閥,在溢流閥主閥溢流時,溢流閥進口壓力可維持為由先導(dǎo)閥彈簧所調(diào)定的定值.先導(dǎo)式溢流閥的另一特點是具有遠程控制口,可很方便地實現(xiàn)系統(tǒng)卸荷或運程調(diào)壓。
溢流閥的泄漏油或流經(jīng)先導(dǎo)閥的油液在返回油祚時有內(nèi)泄和外泄兩種方式.內(nèi)泄時泄漏油流經(jīng)的彈簧腔或先導(dǎo)閥彈簧座通過閥體內(nèi)的連接通道與出油口和通,而外泄是泄露油或流經(jīng)先導(dǎo)閥的油液被直接單獨引回油箱。
應(yīng)用 溢流閥的主要用途:(1)在定量泵的出口并聯(lián)溢流閥可調(diào)節(jié)泵的出口壓力;(2)在變量泵的出口并聯(lián)溢流閥可對系統(tǒng)起到過載保護作用;(3)在回油路上摟入直動式溢流閥可使執(zhí)行元件運動平穩(wěn);(4)利用先導(dǎo)式溢流閥的遠程控制口可實現(xiàn)系統(tǒng)卸荷或遠程調(diào)壓.總之,在系統(tǒng)中溢流閥可作為溢流閥,安全閥,背壓閥使用,可以調(diào)節(jié)系統(tǒng)的壓力或使系統(tǒng)卸荷.
二,減壓閥
功能 減壓閥的功能在于使流經(jīng)減壓閥的油液壓力降低,并使與減壓閥出口連接的回路壓力保持穩(wěn)定.即減壓閥的出口壓力可維持恒定,不受進口壓力及通過流量的影響。
特點 按照結(jié)構(gòu)減壓閥也有直動式和先導(dǎo)式兩種,分別用于不同場合.
堿壓限的閥心處在原始位置上時,它的閥口是打開的,閥的進,出口溝通.閥心由出口處的壓力控制,出口壓力未達到調(diào)定壓力時閥口全開,閥心不動.當出口壓力達到調(diào)定壓力時,閥心上移,閥口關(guān)小,在調(diào)定壓力下達到平衡.當減壓閥的出口處不輸出油液時,它的出口壓力仍能夠基本保持恒定,此時有少量油液經(jīng)先導(dǎo)閥流回油箱。
減壓閥與溢流閥的主要區(qū)別為:(1)減壓閥能保持出口處的壓力基本不變,而溢流閥則保持進口處的壓力基本不變;(2)在不工作時,減壓閥的進出油口互通,溢流閥的進出油口不通;(3)減壓閥要求外泄,其先導(dǎo)閥的彈簧腔需通過泄油口單獨外接油箱,而溢流閥允許內(nèi)泄,其先導(dǎo)閥彈簧腔通過閥體內(nèi)的連接通道與出油口相通,不必單獨外接油箱。
應(yīng)用 減壓閥主要用于降低系統(tǒng)某一支路的油液壓力,在同一系統(tǒng)中得到兩個或多個不同壓力的回路.常用于夾緊支路,潤滑支路或電液動換向閥的控制回路.需要注意的是減壓閥具有壓力損失,當分支油路比主油路的壓力低很多,且流量較大時,可考慮采用高,低壓泵分別供油.
三,順序閥
功能 順序閥的功能在于利用液壓系統(tǒng)中的壓力變化,控制油路通斷來控制多個執(zhí)行元件的順序動作
特點 按照結(jié)構(gòu),順序閥也有直動式和先導(dǎo)式兩種.直動式順序閥結(jié)構(gòu)簡單,動作靈敏但調(diào)定壓力較低,較高壓力時宜采用先導(dǎo)式順序閥.根據(jù)控制壓力來源的不同,順序閥有內(nèi)控式和外控式之分,請注意兩者圖形符號的區(qū)別.內(nèi)控式順序閥在進油路壓力達到設(shè)定壓力之前,閥口一直是關(guān)閉的,達到設(shè)定壓力后閥口打開,使壓力油進入油路;外控式順序閥閥口的開閉與油路進口壓力無關(guān),僅取決于控制油路壓力的大小。
順序閥與溢流閥的主要區(qū)別為:(1)當順序閥的出口與負載油路相通時,泄漏油和先導(dǎo)控制油必須外泄,而溢流閥的出口與回油相通,泄漏油和先導(dǎo)控制油可外泄也可內(nèi)泄;(2)溢流閥的進口壓力是限定的,即閥的調(diào)定壓力,順序閥的進口壓力由負載決定,順序閥開啟后可隨負載增加市進一步升高.
應(yīng)用 順序閥的主要用途為:(1)控制多個執(zhí)行元件的順序動作;(2)內(nèi)控式順序閥可作背壓閥使用;(3)與單向閥并聯(lián)組成平衡閥,鎖定執(zhí)行元件;(4)外控順序閥可用于雙泵供油系統(tǒng)的卸荷.
四,壓力繼電器
壓力繼電器是利用液體壓力信號控制電氣觸點通斷的液壓電氣轉(zhuǎn)換元件,當油液的壓力達到其設(shè)定壓力時,壓力繼電器發(fā)出電信號,以控制電氣元件動作,實現(xiàn)執(zhí)行元件的順序動作或系統(tǒng)的安全保護和動作互鎖。

液壓傳動
與機械傳動相比。液壓傳動更容易實現(xiàn)其運動參數(shù)(流量)和動力參數(shù)(壓力)的控制，而液壓傳動較之液力傳動具有良好的低速負荷特性。由于具有傳遞效率高，可進行恒功率輸出控制，功率利用充分，系統(tǒng)結(jié)構(gòu)簡單，輸出轉(zhuǎn)速無級調(diào)速，可正、反向運轉(zhuǎn)，速度剛性大，動作實現(xiàn)容易等突出優(yōu)點，液壓傳動在工程機械中得到了廣泛的應(yīng)用。幾乎所有工程機械裝備都能見到液壓技術(shù)的蹤跡，其中不少已成為主要的傳動和控制方式。極限負荷調(diào)節(jié)閉式回路，發(fā)動機轉(zhuǎn)速控制的恒壓，恒功率組合調(diào)節(jié)的變量系統(tǒng)開發(fā)，給液壓傳動應(yīng)用于工程機械行走系提供了廣闊的發(fā)展前景。

一、液壓傳動技術(shù)的應(yīng)用
液壓傳動技術(shù)在近代工業(yè)制造中的應(yīng)用
液壓傳動有許多突出的優(yōu)點，因此它的應(yīng)用非常廣泛，如一般工業(yè)用的塑料加工機械、壓力機械、機床等，行走機械中的工程機械、建筑機械、農(nóng)業(yè)機械、汽車等;鋼鐵工業(yè)用的冶金機械、提升裝置、軋輥調(diào)整裝置等;土木水利工程用的防洪閘門及堤壩裝置、河床升降裝置、橋梁操縱機構(gòu)等，發(fā)電廠渦輪機調(diào)速裝置、發(fā)電廠等等。

二、液壓傳動技術(shù)的原理與特點
1、液壓傳動的介紹
液壓傳動是用液體作為工作介質(zhì)來傳遞能量和進行控制的傳動方式。液壓傳動和氣壓傳動并稱為流體傳動，是根據(jù)17世紀帕斯卡提出的液體靜壓力傳動原理而發(fā)展起來的一門新興技術(shù)，是工農(nóng)業(yè)生產(chǎn)中應(yīng)用廣泛的技術(shù)。
2、液壓傳動的優(yōu)點
(1)體積小、重量輕，因此慣性力較小，當突然過載或停車時，不會發(fā)生大的沖擊，
(2)能在給定范圍內(nèi)平穩(wěn)的自動調(diào)節(jié)牽引速度，并可實現(xiàn)無極調(diào)速;
(3)換向容易，在不改變電機旋轉(zhuǎn)方向的情況下，可以較方便地實現(xiàn)工作機構(gòu)旋轉(zhuǎn)和直線往復(fù)運動的轉(zhuǎn)換;
(4)液壓泵和液壓馬達之間用油管連接，在空間布置上彼此不受嚴格限制;
(5) 由于采用油液為工作介質(zhì)，元件相對運動表面間能自行潤滑，磨損小，使用壽命長;
(6)操縱控制簡便，自動化程度高;
(7)容易實現(xiàn)過載保護。
液壓傳動有許多突出的優(yōu)點，因此它的應(yīng)用非常廣泛，如一般工業(yè)用的塑料加工機械、壓力機械、機床等，行走機械中的工程機械、建筑機械、農(nóng)業(yè)機械、汽車等，鋼鐵工業(yè)用的冶金機械、提升裝置、軋輥調(diào)整裝置等，土木水利工程用的防洪閘門及堤壩裝置、河床升降裝置、橋粱操縱機構(gòu)等;發(fā)電廠渦輪機調(diào)速裝置等等，船舶用的甲板起重機械、船頭門、艙壁閥、船尾推進器等，特殊技術(shù)用的控制裝置、測量浮標、升降旋轉(zhuǎn)舞臺等。
3、液壓傳動的基本原理
液壓傳動的基本原理是在密閉的容器內(nèi)，利用有壓力的油液作為工作介質(zhì)來實現(xiàn)能量轉(zhuǎn)換和傳遞動力的。其中的液體稱為工作介質(zhì)，一般為礦物油，它的作用和機械傳動中的皮帶、鏈條和齒輪等傳動元件相類似。液壓傳動是利用帕斯卡原理!帕斯卡原理是大概就是:在密閉環(huán)境中，向液體施加一個力，這個液體會向各個方向傳遞這個力!力的大小不變!液壓傳動就是利用這個物理性質(zhì)，向一個物體施加一個力，利用帕斯卡原理使這個力變大!從而起到舉起重物的效果!
液壓傳動在閥門行業(yè)也得到很大的應(yīng)用,如閥門的機床制造加工設(shè)備、閥門]液壓試驗設(shè)備、閥門的液壓傳動裝置等。
