意大利ATOS比例閥特點: - 可實(shi)現(xian)壓力、速度的無極調(diao)節,避(bi)免了常通的開關式氣閥換向時的沖(chong)擊現(xian)象。
- 能實現遠程控制(zhi)(zhi)和(he)程序控制(zhi)(zhi)。
- 與斷續控制相比,系統簡化,元(yuan)件大大減少。
- 與液(ye)壓比例(li)閥相比,體(ti)積小、重量輕、結(jie)構簡單、成(cheng)本較低,但響應速度比液(ye)壓系(xi)統慢得多(duo),對負載變化也比較敏感。
- 使用功(gong)率小(xiao)、發熱少、噪聲低(di)。
- 不(bu)會發生火災(zai),*。受(shou)溫度變化的影(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(bi)(bi)(bi)例(li)閥(fa)(fa)自動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)可分(fen)(fen)成斷(duan)(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)連(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。斷(duan)(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)即開(kai)關控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。氣動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統(tong)中使用動作(zuo)頻率較低的(de)開(kai)關式(ON-OFF)的(de)換(huan)向閥(fa)(fa)來控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)氣路的(de)通斷(duan)(duan)。靠減壓閥(fa)(fa)來調(diao)節所需要(yao)(yao)的(de)壓力,靠節流(liu)閥(fa)(fa)來調(diao)節所需要(yao)(yao)的(de)流(liu)量(liang)。這(zhe)種傳統(tong)的(de)氣動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統(tong)要(yao)(yao)想要(yao)(yao)有(you)多(duo)個輸出(chu)力和(he)多(duo)個運動速(su)度,就需要(yao)(yao)多(duo)個減壓閥(fa)(fa)、節流(liu)閥(fa)(fa)及換(huan)向閥(fa)(fa)。這(zhe)樣,不僅(jin)元件(jian)(jian)需要(yao)(yao)多(duo),成本高,構成系(xi)(xi)統(tong)復雜,且(qie)許多(duo)元件(jian)(jian)都需要(yao)(yao)預先進(jin)行人工調(diao)節。電氣比(bi)(bi)(bi)例(li)閥(fa)(fa)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)屬于連(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi),其特點是輸出(chu)量(liang)隨輸入(ru)量(liang)的(de)變化(hua)而變化(hua),輸出(chu)量(liang)與輸入(ru)量(liang)之間存在一定的(de)比(bi)(bi)(bi)例(li)關系(xi)(xi)。比(bi)(bi)(bi)例(li)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)有(you)開(kai)環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)閉環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)之分(fen)(fen)。 |
