4WREE6E32-24/G24K31/A1V-655力士樂(lè)比例控制閥

比例閥對(duì)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*、要么*小，沒(méi)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(gè)開度，由此控制通過(guò)流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

特點(diǎn)

1)可實(shí)現(xiàn)壓力、速度的無(wú)極調(diào)節(jié)，避免了常通的開關(guān)式氣閥換向時(shí)的沖擊現(xiàn)象。

2)能實(shí)現(xiàn)遠(yuǎn)程控制和程序控制。

3)與斷續(xù)控制相比，系統(tǒng)簡(jiǎn)化，元件大大減少。

4)與液壓比例閥相比，體積小、重量輕、結(jié)構(gòu)簡(jiǎn)單、成本較低，但響應(yīng)速度比液壓系統(tǒng)慢得多，對(duì)負(fù)載變化也比較敏感。

5)使用功率小、發(fā)熱少、噪聲低。

6)不會(huì)發(fā)生火災(zāi)，不污染環(huán)境。受溫度變化的影響小。

比例閥三種形態(tài)

（1）電磁式 電磁式是指采用比例電磁鐵作為電氣一機(jī)械轉(zhuǎn)換元件的比例閥，比例電磁鐵將輸入的電流信號(hào)轉(zhuǎn)換成力、位移機(jī)械信號(hào)輸出．進(jìn)而控制壓力、流量及方向等參數(shù)。

（2）電動(dòng)式 電動(dòng)式是指采用直流伺服電動(dòng)機(jī)作為電氣一機(jī)械轉(zhuǎn)換元件的比例閥，直流伺服電動(dòng)機(jī)將輸入的電信號(hào)．轉(zhuǎn)換成旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)速，再經(jīng)絲桿螺母、齒輪齒條或齒輪凸輪等減速裝置和變換機(jī)構(gòu)，輸出力與位移，進(jìn)一步控制液壓參數(shù)。

（3）電液式 電液式是指采用力矩馬達(dá)和噴嘴擋板的結(jié)構(gòu)為先導(dǎo)控制級(jí)的比例閥。對(duì)力矩馬達(dá)輸入不同的電信號(hào)，并通過(guò)同它連接在一起的擋板（有時(shí)力矩馬達(dá)的銜鐵就是擋板）輸出位移或角位移，改變擋板和噴嘴之間的距離，使噴嘴噴出的油液流阻產(chǎn)生變化，進(jìn)而控制輸小參數(shù)。

電磁鐵包括開關(guān)式和比例式兩種，開關(guān)式電磁鐵常被安裝在換向閥上，用來(lái)控制閥的換向、系統(tǒng)的卸荷和加載等；比例式電磁鐵安裝在各類比例閥上，用來(lái)控制液流的方向、壓力和流量。不少比例壓力閥安裝在電控變量泵上，可以控制泵的和流量和方向。

電液比例閥是閥內(nèi)比例電磁鐵輸入電壓信號(hào)產(chǎn)生相應(yīng)動(dòng)作，使工作閥閥芯產(chǎn)生位移，閥口尺寸發(fā)生改變并以此完成與輸入電壓成比例壓力、流量輸出元件。閥芯位移也可以以機(jī)械、液壓或電形式進(jìn)行反饋。電液比例閥具有形式種類多樣、容易組成使用電氣及計(jì)算機(jī)控制各種電液系統(tǒng)、控制精度高、安裝使用靈活以及抗污染能力強(qiáng)等多方面優(yōu)點(diǎn)，應(yīng)用領(lǐng)域日益拓寬。
