意大利ATOS比例閥特點： - 可實現(xian)壓力、速度的無極調節，避免了常通(tong)的開關式(shi)氣閥換向時的沖擊現(xian)象。
- 能實現遠程(cheng)控(kong)制和程(cheng)序控(kong)制。
- 與斷續控制相比(bi)，系統簡(jian)化，元件大大減(jian)少。
- 與液壓(ya)比(bi)例(li)閥相比(bi)，體積小、重量輕(qing)、結構(gou)簡單、成本(ben)較(jiao)低，但響應速度(du)比(bi)液壓(ya)系統慢得(de)多，對負載變(bian)化也比(bi)較(jiao)敏感。
- 使(shi)用功率小、發熱少、噪(zao)聲低。
- 不會(hui)發生火災，*。受溫度變化的(de)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。 電氣比(bi)例閥(fa)(fa)(fa)自動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)可(ke)分成斷續控(kong)(kong)(kong)(kong)制(zhi)(zhi)和連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷續控(kong)(kong)(kong)(kong)制(zhi)(zhi)即(ji)開(kai)關控(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)統(tong)中使用動(dong)作(zuo)頻率較低的(de)(de)(de)(de)(de)開(kai)關式(ON-OFF)的(de)(de)(de)(de)(de)換向閥(fa)(fa)(fa)來控(kong)(kong)(kong)(kong)制(zhi)(zhi)氣路的(de)(de)(de)(de)(de)通斷。靠減壓閥(fa)(fa)(fa)來調(diao)節(jie)所需要(yao)的(de)(de)(de)(de)(de)壓力，靠節(jie)流(liu)閥(fa)(fa)(fa)來調(diao)節(jie)所需要(yao)的(de)(de)(de)(de)(de)流(liu)量。這種(zhong)傳統(tong)的(de)(de)(de)(de)(de)氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)統(tong)要(yao)想要(yao)有多(duo)個(ge)輸出(chu)力和多(duo)個(ge)運動(dong)速(su)度(du)，就需要(yao)多(duo)個(ge)減壓閥(fa)(fa)(fa)、節(jie)流(liu)閥(fa)(fa)(fa)及(ji)換向閥(fa)(fa)(fa)。這樣，不僅元件需要(yao)多(duo)，成本高，構成系(xi)統(tong)復雜，且(qie)許多(duo)元件都需要(yao)預先進(jin)行(xing)人(ren)工調(diao)節(jie)。電氣比(bi)例閥(fa)(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)，其特點是輸出(chu)量隨輸入量的(de)(de)(de)(de)(de)變化(hua)而變化(hua)，輸出(chu)量與(yu)輸入量之(zhi)間(jian)存在一(yi)定(ding)的(de)(de)(de)(de)(de)比(bi)例關系(xi)。比(bi)例控(kong)(kong)(kong)(kong)制(zhi)(zhi)有開(kai)環控(kong)(kong)(kong)(kong)制(zhi)(zhi)和閉環控(kong)(kong)(kong)(kong)制(zhi)(zhi)之(zhi)分。 |
