意大利ATOS比例閥特點： - 可(ke)實(shi)現壓力、速度的無極調節，避免了常通的開關式氣閥換向時的沖擊現象。
- 能實現遠程(cheng)控制和程(cheng)序控制。
- 與斷續控制(zhi)相比，系統簡化，元(yuan)件大大減少。
- 與液壓比例閥相比，體積小、重量輕、結構(gou)簡單、成本較低，但響(xiang)應速(su)度(du)比液壓系(xi)統慢得(de)多，對(dui)負(fu)載變化也(ye)比較敏感。
- 使(shi)用功率(lv)小、發(fa)熱少(shao)、噪聲低(di)。
- 不會發(fa)生火(huo)災，*。受溫度變化的影響小。

ATOS阿托斯比例方向閥屬于比例閥的一種，用來控制流量和流向。 電氣(qi)比(bi)(bi)例閥(fa)(fa)(fa)自動(dong)(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)可分(fen)成斷(duan)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)和(he)連(lian)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)即開關(guan)控(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)動(dong)(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong)中使用動(dong)(dong)(dong)(dong)作(zuo)頻率(lv)較低的(de)(de)(de)開關(guan)式(ON-OFF)的(de)(de)(de)換(huan)向閥(fa)(fa)(fa)來控(kong)(kong)(kong)制(zhi)(zhi)氣(qi)路的(de)(de)(de)通斷(duan)。靠減壓閥(fa)(fa)(fa)來調節所需要(yao)(yao)的(de)(de)(de)壓力，靠節流閥(fa)(fa)(fa)來調節所需要(yao)(yao)的(de)(de)(de)流量(liang)。這種傳統(tong)的(de)(de)(de)氣(qi)動(dong)(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong)要(yao)(yao)想要(yao)(yao)有多(duo)(duo)個輸出(chu)(chu)力和(he)多(duo)(duo)個運動(dong)(dong)(dong)(dong)速(su)度，就(jiu)需要(yao)(yao)多(duo)(duo)個減壓閥(fa)(fa)(fa)、節流閥(fa)(fa)(fa)及換(huan)向閥(fa)(fa)(fa)。這樣，不僅元(yuan)件需要(yao)(yao)多(duo)(duo)，成本高，構成系統(tong)復雜，且許多(duo)(duo)元(yuan)件都(dou)需要(yao)(yao)預先進(jin)行人工調節。電氣(qi)比(bi)(bi)例閥(fa)(fa)(fa)控(kong)(kong)(kong)制(zhi)(zhi)屬于連(lian)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)，其特點(dian)是(shi)輸出(chu)(chu)量(liang)隨(sui)輸入(ru)(ru)量(liang)的(de)(de)(de)變化(hua)而變化(hua)，輸出(chu)(chu)量(liang)與輸入(ru)(ru)量(liang)之間存在一(yi)定(ding)的(de)(de)(de)比(bi)(bi)例關(guan)系。比(bi)(bi)例控(kong)(kong)(kong)制(zhi)(zhi)有開環控(kong)(kong)(kong)制(zhi)(zhi)和(he)閉環控(kong)(kong)(kong)制(zhi)(zhi)之分(fen)。 |
