廣泛應(yīng)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(chē)、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

減壓閥是通過(guò)調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門(mén)。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過(guò)改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。
1)調(diào)壓范圍：它是指減壓閥輸出壓力P2的可調(diào)范圍，在此范圍內(nèi)要求達(dá)到規(guī)定的精度。調(diào)壓范圍主要與調(diào)壓彈簧的剛度有關(guān)。
(2)壓力特性：它是指流量g為定值時(shí)，因輸入壓力波動(dòng)而引起輸出壓力波動(dòng)的特性。輸出壓力波動(dòng)越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。
(3)流量特性：它是指輸入壓力—定時(shí)，輸出壓力隨輸出流量g的變化而變化的持性。當(dāng)流量g發(fā)生變化時(shí)，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動(dòng)就越小。
它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質(zhì)主要是水。減壓閥廣泛用于高層建筑、城市給水管網(wǎng)水壓過(guò)高的區(qū)域、礦井及其他場(chǎng)合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆��?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此減壓閥具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30%。
減壓閥的構(gòu)造類(lèi)型很多，以往常見(jiàn)的有薄膜式、內(nèi)彈簧活塞式等。減壓閥的基本作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓。
JB/T2203－1999《減壓閥結(jié)構(gòu)長(zhǎng)度》為主的通用類(lèi)。目前國(guó)內(nèi)大多數(shù)減壓閥生產(chǎn)廠家均按本標(biāo)準(zhǔn)設(shè)計(jì)生產(chǎn)，但本標(biāo)準(zhǔn)也不盡無(wú)缺，規(guī)格不全。氣體減壓閥非常大公稱(chēng)通徑為DN500，水用減壓閥非常大公稱(chēng)通徑DN1000。根據(jù)廠家所生產(chǎn)的減壓閥規(guī)格及掌握的資料來(lái)看，各廠家連接尺寸也不盡統(tǒng)一，建議通用機(jī)械研究所對(duì)JB/T2203－1999《減壓閥結(jié)構(gòu)長(zhǎng)度》進(jìn)行修訂。建議設(shè)計(jì)院及用戶按標(biāo)準(zhǔn)選用，減壓閥生產(chǎn)廠家按標(biāo)準(zhǔn)設(shè)計(jì)制造。

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)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(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)液壓閥的手動(dòng)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)、
