詳細(xì)介紹
美國(guó)阿斯卡比例閥: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。靠減壓閥來(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)控制系統(tǒng)要想要有多個(gè)輸出力和多個(gè)運(yùn)動(dòng)速度,就需要多個(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)。電氣比例閥控制屬于連續(xù)控制,其特點(diǎn)是輸出量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。

ASCO比例閥特點(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),*。受溫度變化的影響小。

美國(guó)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(méi)有噴嘴擋板機(jī)構(gòu),故閥對(duì)雜質(zhì)不敏感,可靠性高。
