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。它由機(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.

4WRZE25W8-220-7X/6EG24N9EK31/F1D3M比例閥

不帶電氣位置反饋，帶集成電子元件 (OBE) 的先導(dǎo)式比例方向閥

4WRZE

規(guī)格 10, 16, 25, 32

組件系列 7X

較大工作壓力 350 bar

較大流量 1600 l/min

先導(dǎo)式比例方向閥型號 4WRZ(E)… 和 5WRZ(E).52…

型號為 4WRZ(E)... 的閥門是由比例電磁鐵啟動的先導(dǎo)式四通方向閥。它們的功能是控制流動方向和流量。

5WRZ(E)… 型閥門配有附加油口“R”（僅限于 NG52）。

設(shè)置：

閥門的基本構(gòu)成包括：

帶比例電磁鐵（5 和 6）的先導(dǎo)控制閥 (9)

帶主控制閥芯 (11) 和對中彈簧 (12) 的主閥 (10)

功能：

線圈（5、6）斷電后，主控制閥芯 (11) 將通過對中彈簧 (12) 保持在中心位置。

主控制閥芯 (11) 由先導(dǎo)控制閥 (9) 控制；主控制閥芯成比例移動，例如，通過啟動線圈“b”(6)。

→ 控制閥芯 (2) 向右移動，先導(dǎo)油通過先導(dǎo)控制閥 (9) 流入壓力腔 (13)，并使主控制閥芯 (11) 根據(jù)電氣輸入信號成比例轉(zhuǎn)動。

→ 通過具有漸進(jìn)流體特性的節(jié)流橫截面，進(jìn)行從 P 到 A 及從 B 到 T 的連接

先導(dǎo)油可通過油口 P 從內(nèi)部供給先導(dǎo)控制閥，也可通過油口 X 從外部供給先導(dǎo)控制閥。

關(guān)閉線圈 (6)

→ 控制閥芯 (2) 和主控制閥芯 (11) 移回至中心位置

根據(jù)閥芯位置，液壓油可從 P 流到 A，從 B 流到 T，或從 P 流到 B，從 A 流到 T (R)。

可選手動應(yīng)急操作（14 和 15）可在線圈不通電的情況下用于移動控制閥芯 (2)。

注意：

意外激活手動應(yīng)急操作可能會導(dǎo)致不受控制的機(jī)器運(yùn)動！

注意：

由于設(shè)計(jì)原理，閥內(nèi)固有內(nèi)部泄漏，泄漏量可能隨著使用年限而增加。

閥門是在流體系統(tǒng)中，用來控制流體的方向、壓力、流量的裝置，是使配管和設(shè)備內(nèi)的介質(zhì)（液體、氣體、粉末）流動或停止并能控制其流量的裝置。

閥門是管路流體輸送系統(tǒng)中控制部件，用來改變通路斷面和介質(zhì)流動方向，具有導(dǎo)流、截止、節(jié)流、止回、分流或溢流卸壓等功能。用于流體控制的閥門，從較簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格繁多， 閥門的公稱通徑從極微小的儀表閥大至通徑達(dá)10m的工業(yè)管路用閥。可用于控制水、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、 液態(tài)金屬和放射性流體等各種類型流體地流動 ，閥門的工作壓力可以從0.0013MPa到1000MPa 的非常高壓，工作溫度可以c-270℃的超低溫到1430℃的高溫。

閥門的控制可采用多種傳動方式， 如手動、電動、液動、氣動、渦輪、電磁動、電磁液動、電液動、氣液動、正齒輪、傘齒輪驅(qū)動等；可以在壓力、溫度或其它形式傳感信號的作用下， 按預(yù)定的要求動作，或者不依賴傳感信號而進(jìn)行簡單的開啟或關(guān)閉，閥門依靠驅(qū)動或自動機(jī)構(gòu)使啟閉件作升降、滑移、旋擺或回轉(zhuǎn)運(yùn)動， 從而改變其流道面積的大小以實(shí)現(xiàn)其控制功能。

按作用和用途

（一）關(guān)斷閥

這類閥門是起開閉作用的。常設(shè)于冷、熱源進(jìn)、出口，設(shè)備進(jìn)、出口，管路分支線（包括立管）上，也可用作放水閥和放氣閥。常見的關(guān)斷閥有閘閥、截止閥、球閥和蝶閥等。

閘閥可分為明桿和暗桿、單閘板與雙閘板、楔形閘板與平行閘板等。閘閥關(guān)閉嚴(yán)密性不好，大直徑閘閥開啟困難；沿水流方向閥體尺寸小，流動阻力小，閘閥公稱直徑跨度大。

截止閥按介質(zhì)流向分直通式、直角式和直流式三種，有明桿和暗桿之分。截止閥的關(guān)閉嚴(yán)密性較閘閥好，閥體長，流動阻力大，較大公稱直徑為DN200。

球閥的閥芯為開孔的圓球。板動閥桿使球體開孔正對管道軸線時(shí)為全開，轉(zhuǎn)90°為全閉。球閥有一定的調(diào)節(jié)性能，關(guān)閉較嚴(yán)密。

蝶閥的閥芯為圓形閥板，它可沿垂直管道軸線的立軸轉(zhuǎn)動。當(dāng)閥板平面與管子軸線一致時(shí)，為全開；閘板平面與管子軸線垂直時(shí)，為全閉。蝶閥閥體長度小，流動阻力小，比閘閥和截止閥價(jià)格高。 [1] 

（二）止回閥

這類閥門用于防止介質(zhì)倒流，利用流體自身的動能自行開啟，反向流動時(shí)自動關(guān)閉。常設(shè)于水泵的出口、疏水器出口以及其他不允許流體反向流動的地方。止回閥分旋啟式、升降式和對夾式三種。對于旋啟式止回閥，流體只能從左向右流動時(shí)，反向流動時(shí)自動關(guān)閉。對于升降式止回閥，流體從左向右流動時(shí)，閥芯抬起，形成通路，反向流動時(shí)閥芯被壓緊到閥座上而被關(guān)閉。對于對夾式止回閥，流體從左向右流動時(shí)，閥芯被開啟，形成通路，反向流動時(shí)閥芯被壓緊到閥座上而被關(guān)閉，對夾式止回閥可多位安裝、體積小、重量輕、結(jié)構(gòu)緊湊。 [1] 

（三）調(diào)節(jié)閥

閥門前后壓差一定，普通閥門的開度在較大范圍內(nèi)變化時(shí)，其流量變化不大，而到某一開度時(shí)，流量急劇變化，即調(diào)節(jié)性能不佳。調(diào)節(jié)閥可以按照信號的方向和大小，改變閥芯行程來改變閥門的阻力數(shù)，從而達(dá)到調(diào)節(jié)流量目的的閥門。調(diào)節(jié)閥分手動調(diào)節(jié)閥和自動調(diào)節(jié)閥，而手動或自動調(diào)節(jié)閥又分許多種類，其調(diào)節(jié)性能也是不同的。自動調(diào)節(jié)閥有自力式流量調(diào)節(jié)閥和自力式壓差調(diào)節(jié)閥等。 [1] 

（四）真空類

真空類包括真空球閥、真空擋板閥、真空充氣閥、氣動真空閥等。其作用是在真空系統(tǒng)中，用來改變氣流方向，調(diào)節(jié)氣流量大小，切斷或接通管路的真空系統(tǒng)元件稱為真空閥門。

（五）特殊用途類

特殊用途類包括清管閥、放空閥、排污閥、排氣閥、過濾器等。

排氣閥是管道系統(tǒng)中必不可少的輔助元件，廣泛應(yīng)用于鍋爐、空調(diào)、石油天然氣、給排水管道中。往往安裝在制高點(diǎn)或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。
