自動(dòng)控制可分成斷續(xù)控制和連續(xù)控制。斷續(xù)控制即開關(guān)控制。氣動(dòng)控制系統(tǒng)中使用動(dòng)作頻率較低的開關(guān)式(ON-OFF)的換向閥來(lái)控制氣路的通斷?？繙p壓閥來(lái)調(diào)節(jié)所需要的壓力，靠節(jié)流閥來(lái)調(diào)節(jié)所需要的流量。這種傳統(tǒng)的氣動(dòng)控統(tǒng)要制系想要有多個(gè)輸出力多個(gè)減壓閥、節(jié)流閥及換向閥。這樣，不僅元件需要多，成本高，構(gòu)成系統(tǒng)復(fù)雜，且許多元件都需要預(yù)先進(jìn)行人工調(diào)節(jié)。parker派克電氣比例閥控制屬于連續(xù)控制，其特點(diǎn)是輸出量和多個(gè)運(yùn)動(dòng)速度，就需要隨輸入量的變化而變化，輸出量與輸入量之間存在一定的比例關(guān)系。比例控制有開環(huán)控制和閉環(huán)控制之分。
parker派克電氣比例閥結(jié)構(gòu)原理：輸入信號(hào)增大，供氣用電磁閥先導(dǎo)閥1換向，而排氣用電磁先導(dǎo)閥7處于復(fù)位狀態(tài)，則供氣壓力從SUP口通過(guò)閥1進(jìn)入先導(dǎo)室5，先導(dǎo)室壓力上升，氣壓力作用在膜片2的上方，則和膜片2相連的供氣閥芯4便開啟，排氣閥芯3關(guān)閉，產(chǎn)生輸出壓力。此輸出壓力通過(guò)壓力傳感器6反饋至控制回路8。在這里，與目標(biāo)值進(jìn)行快速比較修正，知道輸出壓力與輸入信號(hào)成一定比例為止，從而得到輸出壓力與輸入信號(hào)的變化成比例的變化。由于沒有噴嘴擋板機(jī)構(gòu)，故閥對(duì)雜質(zhì)不敏感，可靠性高。
*比例閥，parker派克電氣比例閥作用：以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)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，parker派克電氣比例閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。
特點(diǎn)：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。能實(shí)現(xiàn)遠(yuǎn)程控制和程序控制。與斷續(xù)控制相比，系統(tǒng)簡(jiǎn)化，元件大大減少。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。使用功率小、發(fā)熱少、噪聲低。不會(huì)發(fā)生火災(zāi)，*。受溫度變化的影響小。
