意大利ATOS比例閥特點: - 可(ke)實現壓力、速(su)度(du)的(de)無極調節,避免(mian)了常通的(de)開關式氣閥(fa)換向(xiang)時的(de)沖擊現象。
- 能實現遠程控(kong)制(zhi)和程序控(kong)制(zhi)。
- 與斷續(xu)控制相比(bi),系統簡化,元件大大減少。
- 與液(ye)(ye)壓(ya)(ya)比(bi)(bi)例閥相比(bi)(bi),體(ti)積小(xiao)、重(zhong)量輕、結構簡單、成(cheng)本較低,但響(xiang)應速度(du)比(bi)(bi)液(ye)(ye)壓(ya)(ya)系統慢(man)得多,對負載變化也(ye)比(bi)(bi)較敏感。
- 使用功率小、發熱少、噪(zao)聲低。
- 不(bu)會發生火(huo)災,*。受溫度變(bian)化的影(ying)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。 電氣比例(li)閥(fa)自動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分(fen)成斷續控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和連(lian)續控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。斷續控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)即開關(guan)(guan)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。氣動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)中使用動作頻率較低的(de)開關(guan)(guan)式(ON-OFF)的(de)換向閥(fa)來(lai)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)氣路(lu)的(de)通斷。靠減(jian)壓閥(fa)來(lai)調(diao)(diao)節(jie)所需要的(de)壓力,靠節(jie)流閥(fa)來(lai)調(diao)(diao)節(jie)所需要的(de)流量。這種傳(chuan)統(tong)的(de)氣動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)要想要有(you)多(duo)(duo)(duo)個輸(shu)出力和多(duo)(duo)(duo)個運動速度,就需要多(duo)(duo)(duo)個減(jian)壓閥(fa)、節(jie)流閥(fa)及換向閥(fa)。這樣,不僅元(yuan)件需要多(duo)(duo)(duo),成本高,構成系(xi)統(tong)復雜,且許(xu)多(duo)(duo)(duo)元(yuan)件都需要預(yu)先(xian)進行人(ren)工調(diao)(diao)節(jie)。電氣比例(li)閥(fa)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)屬(shu)于連(lian)續控(kong)(kong)制(zhi)(zhi)(zhi)(zhi),其特(te)點是輸(shu)出量隨輸(shu)入(ru)量的(de)變化而變化,輸(shu)出量與輸(shu)入(ru)量之間存在一(yi)定的(de)比例(li)關(guan)(guan)系(xi)。比例(li)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)有(you)開環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和閉環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)之分(fen)。 |
