意大利阿托斯比例閥DPZO-AE-171-S5/E ATOS比例閥特點: - 可實現壓(ya)力、速(su)度(du)的(de)無(wu)極調節(jie),避免了常通的(de)開關(guan)式氣閥換向時(shi)的(de)沖擊現象(xiang)。
- 能(neng)實現遠(yuan)程控(kong)制和程序控(kong)制。
- 與斷續控制相比,系統簡(jian)化,元件大大減少。
- 與液壓比例閥相比,體積小(xiao)、重量輕(qing)、結(jie)構(gou)簡單、成(cheng)本較低,但響(xiang)應速度比液壓系統慢(man)得多,對負載變化也比較敏(min)感。
- 使用功率小、發熱少、噪(zao)聲低(di)。
- 不會發生火(huo)災,*。受(shou)溫(wen)度變化的(de)影響小(xiao)。

ATOS阿托斯比例閥向閥屬于比例閥的一種,用來控制流量和流向。 電(dian)氣比(bi)(bi)例(li)閥(fa)自動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)可分成(cheng)斷(duan)(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和連(lian)(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。斷(duan)(duan)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)即(ji)開(kai)(kai)關控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)。氣動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)(tong)中使(shi)用動(dong)作頻(pin)率較(jiao)低的(de)(de)開(kai)(kai)關式(ON-OFF)的(de)(de)換(huan)向(xiang)閥(fa)來控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)氣路的(de)(de)通(tong)斷(duan)(duan)。靠(kao)(kao)減壓閥(fa)來調(diao)節(jie)所(suo)需(xu)要的(de)(de)壓力,靠(kao)(kao)節(jie)流閥(fa)來調(diao)節(jie)所(suo)需(xu)要的(de)(de)流量。這種傳統(tong)(tong)的(de)(de)氣動(dong)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)(tong)要想要有多(duo)個輸(shu)(shu)出力和多(duo)個運動(dong)速度,就需(xu)要多(duo)個減壓閥(fa)、節(jie)流閥(fa)及換(huan)向(xiang)閥(fa)。這樣,不僅元(yuan)件(jian)(jian)需(xu)要多(duo),成(cheng)本(ben)高,構(gou)成(cheng)系(xi)統(tong)(tong)復雜,且(qie)許多(duo)元(yuan)件(jian)(jian)都需(xu)要預先進(jin)行(xing)人工(gong)調(diao)節(jie)。電(dian)氣比(bi)(bi)例(li)閥(fa)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)屬(shu)于連(lian)(lian)續(xu)(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),其特點(dian)是輸(shu)(shu)出量隨輸(shu)(shu)入(ru)量的(de)(de)變化(hua)(hua)而變化(hua)(hua),輸(shu)(shu)出量與輸(shu)(shu)入(ru)量之間存在一(yi)定的(de)(de)比(bi)(bi)例(li)關系(xi)。比(bi)(bi)例(li)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)有開(kai)(kai)環(huan)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和閉環(huan)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)之分。 |
