電液比例閥簡(jiǎn)稱比例閥。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)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。

比例溢流閥

1)比例環(huán)節(jié)

比例環(huán)節(jié)也稱為無(wú)慣性環(huán)節(jié),對(duì)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(guò)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(wú)反饋分為開(kāi)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(kāi)環(huán)控制系統(tǒng)的精度比較低,無(wú)級(jí)調(diào)節(jié)系統(tǒng)輸入量就可以無(wú)級(jí)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(jiǎn)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(duì)系統(tǒng)輸入控制作用沒(méi)有影響,沒(méi)有自動(dòng)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(chǎng)合。開(kāi)環(huán)控制系統(tǒng)一.般不存在所謂穩(wěn)定性問(wèn)題。

閉環(huán)控制系統(tǒng)(即反饋控制系統(tǒng))的優(yōu)點(diǎn)是對(duì)內(nèi)部和外部干擾不敏感，系統(tǒng)工作原理是反饋控制原理或按偏差調(diào)整原理。這種控制系統(tǒng)有通

過(guò)負(fù)反饋控制自動(dòng)糾正偏差的能力。但反饋帶來(lái)了系統(tǒng)的穩(wěn)定性問(wèn)題，只要系統(tǒng)穩(wěn)定，閉環(huán)控制系統(tǒng)可以保持較高的精度。因此, 目前普遍采用閉環(huán)控制系統(tǒng)。

力士樂(lè)REXROTH比例減壓閥，先導(dǎo)操作DBEM

流量閥是由一個(gè)手動(dòng)調(diào)節(jié)閥組和一個(gè)自動(dòng)平衡閥組組成。調(diào)節(jié)閥組作用是設(shè)定流量，自動(dòng)平衡閥組作用是維持流量恒定。系統(tǒng)流體的工作壓力為P1，手動(dòng)調(diào)節(jié)閥的前后壓力分別為P2、P3。當(dāng)手動(dòng)調(diào)節(jié)閥調(diào)到某一位置時(shí)，即人為確定了“設(shè)定流量”Kv即手動(dòng)調(diào)節(jié)閥的流量系數(shù)，流量G=Kv（P2-P3），Kv為，Kv設(shè)定后，只要P2－P3不變，則流量G不變。當(dāng)系統(tǒng)流量加大時(shí)，(P2—P3)的實(shí)際值超過(guò)了允許的給定值，此時(shí)通過(guò)感壓膜和彈簧作用使自動(dòng)調(diào)節(jié)閥組自動(dòng)關(guān)小，直至流量重新維持到設(shè)定流量，反之亦然。
