意大利ATOS比例閥特點: - 可實現壓力(li)、速(su)度的無(wu)極(ji)調(diao)節,避免了常通的開關式(shi)氣閥換向時的沖擊(ji)現象。
- 能實(shi)現遠程(cheng)控制和程(cheng)序控制。
- 與斷續(xu)控制相比,系統(tong)簡化,元件大大減少。
- 與液壓比例閥(fa)相比,體積小(xiao)、重量輕、結(jie)構簡單、成本(ben)較低,但(dan)響(xiang)應速度比液壓系統慢得(de)多,對(dui)負(fu)載變(bian)化(hua)也比較敏感。
- 使用功率小(xiao)、發熱少、噪(zao)聲低。
- 不會發生(sheng)火(huo)災,*。受溫度變(bian)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(dian)(dian)氣比例閥自動(dong)控(kong)制(zhi)(zhi)(zhi)(zhi)可分(fen)成(cheng)(cheng)斷(duan)續控(kong)制(zhi)(zhi)(zhi)(zhi)和(he)連續控(kong)制(zhi)(zhi)(zhi)(zhi)。斷(duan)續控(kong)制(zhi)(zhi)(zhi)(zhi)即開關控(kong)制(zhi)(zhi)(zhi)(zhi)。氣動(dong)控(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統中使用動(dong)作頻率較(jiao)低(di)的開關式(ON-OFF)的換(huan)向(xiang)閥來控(kong)制(zhi)(zhi)(zhi)(zhi)氣路的通(tong)斷(duan)。靠(kao)減壓閥來調節(jie)所(suo)需(xu)要(yao)(yao)(yao)的壓力(li),靠(kao)節(jie)流閥來調節(jie)所(suo)需(xu)要(yao)(yao)(yao)的流量。這種傳統的氣動(dong)控(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統要(yao)(yao)(yao)想要(yao)(yao)(yao)有多(duo)個輸(shu)出力(li)和(he)多(duo)個運動(dong)速度,就需(xu)要(yao)(yao)(yao)多(duo)個減壓閥、節(jie)流閥及換(huan)向(xiang)閥。這樣,不僅元(yuan)件需(xu)要(yao)(yao)(yao)多(duo),成(cheng)(cheng)本高,構成(cheng)(cheng)系(xi)統復雜(za),且許多(duo)元(yuan)件都需(xu)要(yao)(yao)(yao)預(yu)先進行人工(gong)調節(jie)。電(dian)(dian)氣比例閥控(kong)制(zhi)(zhi)(zhi)(zhi)屬于連續控(kong)制(zhi)(zhi)(zhi)(zhi),其(qi)特點是輸(shu)出量隨輸(shu)入量的變化(hua)而變化(hua),輸(shu)出量與輸(shu)入量之間存在一定的比例關系(xi)。比例控(kong)制(zhi)(zhi)(zhi)(zhi)有開環(huan)控(kong)制(zhi)(zhi)(zhi)(zhi)和(he)閉(bi)環(huan)控(kong)制(zhi)(zhi)(zhi)(zhi)之分(fen)。 |
