閥對流量的控制可以分為兩種：

一種是開關(guān)控制：要么全開、要么全關(guān)，流量要么大、要么小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。

另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個開度，由此控制通過流量的大小，這類閥有手動控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

所以使用比例閥或伺服閥的目的就是：以電控方式實(shí)現(xiàn)對流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動也可實(shí)現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗�需要一定的流量來維持前置級控制油路的工作。

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。

 

比例溢流閥

1)比例環(huán)節(jié)

比例環(huán)節(jié)也稱為無慣性環(huán)節(jié),對液壓缸或馬達(dá)，忽略液壓油的可壓縮性和泄漏,液壓缸的流量Q= VA。其中V為活塞速度;A為活塞面積。其傳遞函數(shù)為: g(s)= V (s)/Q(s)= 1/A =式中K為比例環(huán)節(jié)放大系數(shù)或增益,表示輸入量經(jīng)過放大K倍后輸出。

(2)比例控制系統(tǒng)

比例控制系統(tǒng)根據(jù)有無反饋分為開環(huán)控制和閉環(huán)控制。如比例閥控制液壓缸或馬達(dá)系統(tǒng)可以實(shí)現(xiàn)速度位移轉(zhuǎn)速和轉(zhuǎn)矩等的控制。

由于開環(huán)控制系統(tǒng)的精度比較低,無級調(diào)節(jié)系統(tǒng)輸入量就可以無級調(diào)節(jié)系統(tǒng)輸出量力速度以及加減速度等。這種控制系統(tǒng)的結(jié)構(gòu)組成簡單,系統(tǒng)的輸出端和輸入端不存在反饋回路,系統(tǒng)輸出量對系統(tǒng)輸入控制作用沒有影響,沒有自動糾正偏差的能力,其控制精度主要取決于關(guān)鍵元器件的特性和系統(tǒng)調(diào)整精度，所以只能應(yīng)用在精度要求不高并且不存在內(nèi)外干擾的場合。開環(huán)控制系統(tǒng)一.般不存在所謂穩(wěn)定性問題。

比例控制閥

采用比例電磁鐵(或力矩馬達(dá))將輸入信號轉(zhuǎn)換成力或閥的機(jī)械位移，使閥的輸出(壓力、流量)也按照其輸入量連續(xù)、成比例地進(jìn)行控制的閥。

大型鋼廠現(xiàn)場使用的比例閥主要有下表中的幾種:伺服比例控制閥、比例控制閥、電液比例控制閥，比例閥，伺服閥。

1、4WRD E..型比例伺服控制閥(高頻響閥)

結(jié)構(gòu)和功能

4WRDE型閥是三級高頻響方向閥。該閥可用于開環(huán)控制或閉環(huán)調(diào)節(jié)液流的大小和方向，但主要用于閉環(huán)調(diào)節(jié)回路中。

閥主要由下列部分組成:

1.二級先導(dǎo)控制閥由力矩馬達(dá)( 1 )和由噴嘴擋板閥構(gòu)成的液壓放大器( 5),和用作流量放大級的閥芯襯套組件(6 )(用以控制第三級(7 ))組成。

2.第三級(7)用于流量控制。

3.感應(yīng)式位移傳感器( 8),連接第三級主閥芯( 10)的磁芯(9 )

通過內(nèi)置電子放大器實(shí)現(xiàn)閥閉環(huán)控制信號邏輯連接,位置檢測系統(tǒng)反饋,和先導(dǎo)閥的控制。

給定值/實(shí)際值比較得到的差動電壓經(jīng)過電子控制器放大, 并作為控制偏差量傳遞到閥的一級。這個信號推動兩個控制噴嘴( 3.1, 3.2) 之間的擋板( 2)因而在兩個控制腔(11.1.11.2)產(chǎn)生了壓差。控制閥芯(4 )因此被推動,并通過相應(yīng)的液流流到彈簧腔(12.1or12.2)閥芯(10)和帶磁芯(9)的位移傳感器(8)-直運(yùn)動,直到實(shí)際值和給定值信號再一次相等。在控制條件下;主閥芯( 10 )一直被保持在給定值所對應(yīng)的位置。

閥芯行程和給定值成正比。通過閥芯( 10 )相對于控制邊( 13 )的位置,形成相應(yīng)的與流量成正比的閥口開度。

閥的動態(tài)特性通過電子放大器優(yōu)化。電子放大器內(nèi)置于閥上(振蕩器,解調(diào)器)

零點(diǎn)調(diào)節(jié)由廠家預(yù)先設(shè)定,通過閉環(huán)控制電子放大器內(nèi)的電位器, 零點(diǎn)能在名義行程士10%范圍內(nèi)調(diào)整。移去閥蓋尾部的插頭,可以對內(nèi)置閉環(huán)電子放大器進(jìn)行操作。

力士樂REXROTH三位四通高響應(yīng)換向閥、先導(dǎo)式、電氣位置反饋和集成電子放大版（OBE）4WRLE.E(W)

蝶閥(英文：butterfly valve)是指關(guān)閉件(閥瓣或蝶板)為圓盤，圍繞閥軸旋轉(zhuǎn)來達(dá)到開啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開到全關(guān)通常是小于90° ，蝶閥和蝶桿本身沒有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門的操作性能。工業(yè)專項(xiàng)使用蝶閥的特點(diǎn)：能耐高溫，適用壓力范圍也較高，閥門公稱通徑大，閥體采用碳鋼制造，閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。
