意大利ATOS比例閥特點: - 可實現壓力、速度的(de)(de)無極調節,避免了常通的(de)(de)開關式氣(qi)閥換向時的(de)(de)沖(chong)擊現象。
- 能實現(xian)遠程控(kong)制和(he)程序控(kong)制。
- 與斷續(xu)控制相比,系統簡化,元件大大減少。
- 與(yu)液(ye)壓(ya)比(bi)例閥相比(bi),體積小、重量輕、結(jie)構簡單、成本較低,但響應(ying)速度比(bi)液(ye)壓(ya)系統慢得多,對負載變化也比(bi)較敏感。
- 使用功率小、發熱少、噪聲低。
- 不會發生火(huo)災,*。受溫(wen)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)比例閥(fa)自動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分成(cheng)斷續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)連(lian)續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。斷續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)即(ji)開(kai)關控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統中使用動(dong)作頻率較(jiao)低的(de)(de)開(kai)關式(ON-OFF)的(de)(de)換(huan)向閥(fa)來(lai)(lai)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)氣(qi)路的(de)(de)通斷。靠減(jian)壓閥(fa)來(lai)(lai)調節所需(xu)(xu)要(yao)(yao)的(de)(de)壓力(li)(li),靠節流(liu)閥(fa)來(lai)(lai)調節所需(xu)(xu)要(yao)(yao)的(de)(de)流(liu)量。這(zhe)種傳統的(de)(de)氣(qi)動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統要(yao)(yao)想要(yao)(yao)有多(duo)個輸(shu)(shu)出力(li)(li)和(he)多(duo)個運動(dong)速度,就(jiu)需(xu)(xu)要(yao)(yao)多(duo)個減(jian)壓閥(fa)、節流(liu)閥(fa)及(ji)換(huan)向閥(fa)。這(zhe)樣,不僅元(yuan)件(jian)需(xu)(xu)要(yao)(yao)多(duo),成(cheng)本(ben)高,構(gou)成(cheng)系(xi)統復雜,且許多(duo)元(yuan)件(jian)都需(xu)(xu)要(yao)(yao)預(yu)先進行人工調節。電氣(qi)比例閥(fa)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)屬于連(lian)續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi),其特點是輸(shu)(shu)出量隨輸(shu)(shu)入量的(de)(de)變化而變化,輸(shu)(shu)出量與輸(shu)(shu)入量之(zhi)間存在一(yi)定的(de)(de)比例關系(xi)。比例控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)有開(kai)環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)閉環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)之(zhi)分。 |
