意大利ATOS比例閥特點: - 可實現壓(ya)力、速度(du)的(de)無極調節,避免了(le)常通的(de)開關(guan)式氣閥(fa)換向時的(de)沖擊現象(xiang)。
- 能實現遠程控制(zhi)和程序控制(zhi)。
- 與斷續控制(zhi)相(xiang)比,系統簡(jian)化,元件大(da)大(da)減少(shao)。
- 與液(ye)壓比例(li)閥相比,體積小、重量輕、結構簡單、成本較(jiao)低,但(dan)響應速(su)度(du)比液(ye)壓系統慢得(de)多,對負載變化也比較(jiao)敏感。
- 使(shi)用功率小、發熱少、噪聲低。
- 不(bu)會發生火災,*。受溫度變化的影響(xiang)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。 電氣比(bi)(bi)(bi)例(li)閥(fa)自動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)可(ke)分成斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開關控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統中使用動(dong)(dong)作(zuo)頻率較低的(de)(de)開關式(shi)(ON-OFF)的(de)(de)換(huan)向閥(fa)來(lai)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣路(lu)的(de)(de)通(tong)斷(duan)。靠減(jian)(jian)壓(ya)閥(fa)來(lai)調(diao)節所需(xu)(xu)(xu)要(yao)的(de)(de)壓(ya)力(li),靠節流閥(fa)來(lai)調(diao)節所需(xu)(xu)(xu)要(yao)的(de)(de)流量(liang)。這種傳統的(de)(de)氣動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統要(yao)想要(yao)有多(duo)個(ge)輸(shu)(shu)出(chu)力(li)和(he)多(duo)個(ge)運動(dong)(dong)速度,就需(xu)(xu)(xu)要(yao)多(duo)個(ge)減(jian)(jian)壓(ya)閥(fa)、節流閥(fa)及換(huan)向閥(fa)。這樣,不僅元件(jian)需(xu)(xu)(xu)要(yao)多(duo),成本高,構成系(xi)統復(fu)雜,且許多(duo)元件(jian)都(dou)需(xu)(xu)(xu)要(yao)預先進行人工調(diao)節。電氣比(bi)(bi)(bi)例(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬(shu)于連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi),其特點是輸(shu)(shu)出(chu)量(liang)隨輸(shu)(shu)入量(liang)的(de)(de)變化而(er)變化,輸(shu)(shu)出(chu)量(liang)與(yu)輸(shu)(shu)入量(liang)之間存在(zai)一(yi)定的(de)(de)比(bi)(bi)(bi)例(li)關系(xi)。比(bi)(bi)(bi)例(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)閉(bi)環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)之分。 |
