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(mian)了(le)常(chang)通的(de)(de)開關式氣閥換向(xiang)時的(de)(de)沖擊現象。
- 能實現遠程控制和程序控制。
- 與斷(duan)續控制相比，系統簡化，元件大大減少。
- 與(yu)液壓比(bi)例閥(fa)相比(bi)，體積小、重量輕、結(jie)構(gou)簡(jian)單(dan)、成本較低，但響應速度比(bi)液壓系統慢得(de)多(duo)，對負載變化(hua)也比(bi)較敏感。
- 使(shi)用功(gong)率小、發(fa)熱少、噪聲低(di)。
- 不(bu)會發生火災，*。受溫度變(bian)化的(de)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(qi)(qi)比例閥(fa)(fa)自動(dong)控(kong)(kong)(kong)(kong)制(zhi)可(ke)分成(cheng)(cheng)斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)和連續(xu)控(kong)(kong)(kong)(kong)制(zhi)。斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)即開關控(kong)(kong)(kong)(kong)制(zhi)。氣(qi)(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)統(tong)中使(shi)用動(dong)作頻(pin)率較低(di)的(de)開關式(ON-OFF)的(de)換(huan)向(xiang)(xiang)閥(fa)(fa)來控(kong)(kong)(kong)(kong)制(zhi)氣(qi)(qi)路的(de)通斷。靠減(jian)壓閥(fa)(fa)來調節所需(xu)(xu)要(yao)(yao)的(de)壓力，靠節流(liu)閥(fa)(fa)來調節所需(xu)(xu)要(yao)(yao)的(de)流(liu)量。這種傳統(tong)的(de)氣(qi)(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)統(tong)要(yao)(yao)想要(yao)(yao)有多(duo)(duo)個輸(shu)出力和多(duo)(duo)個運(yun)動(dong)速度，就需(xu)(xu)要(yao)(yao)多(duo)(duo)個減(jian)壓閥(fa)(fa)、節流(liu)閥(fa)(fa)及換(huan)向(xiang)(xiang)閥(fa)(fa)。這樣，不僅(jin)元件(jian)需(xu)(xu)要(yao)(yao)多(duo)(duo)，成(cheng)(cheng)本高，構成(cheng)(cheng)系(xi)統(tong)復雜，且許多(duo)(duo)元件(jian)都需(xu)(xu)要(yao)(yao)預先進行(xing)人工調節。電氣(qi)(qi)比例閥(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)屬于連續(xu)控(kong)(kong)(kong)(kong)制(zhi)，其特點(dian)是(shi)輸(shu)出量隨輸(shu)入量的(de)變化(hua)而變化(hua)，輸(shu)出量與輸(shu)入量之間存在一定的(de)比例關系(xi)。比例控(kong)(kong)(kong)(kong)制(zhi)有開環(huan)控(kong)(kong)(kong)(kong)制(zhi)和閉環(huan)控(kong)(kong)(kong)(kong)制(zhi)之分。 |
