意大利ATOS比例閥特點： - 可實現壓力、速(su)度的無極調節，避免了常通(tong)的開關式(shi)氣閥換(huan)向時(shi)的沖(chong)擊現象(xiang)。
- 能實現(xian)遠程控制(zhi)和程序控制(zhi)。
- 與斷續(xu)控制相比，系(xi)統簡(jian)化(hua)，元件大(da)大(da)減少。
- 與液壓比(bi)例閥(fa)相比(bi)，體積小、重(zhong)量輕、結構(gou)簡單(dan)、成本較(jiao)低，但響(xiang)應速度比(bi)液壓系統(tong)慢得多，對負載變(bian)化也(ye)比(bi)較(jiao)敏感。
- 使(shi)用功率小、發熱(re)少、噪聲低。
- 不會發(fa)生火(huo)災(zai)，*。受溫(wen)度變化(hua)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(qi)比(bi)例(li)(li)閥(fa)自動(dong)控(kong)(kong)(kong)(kong)(kong)制可分(fen)成(cheng)斷續控(kong)(kong)(kong)(kong)(kong)制和連續控(kong)(kong)(kong)(kong)(kong)制。斷續控(kong)(kong)(kong)(kong)(kong)制即開(kai)(kai)關控(kong)(kong)(kong)(kong)(kong)制。氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制系統中使用動(dong)作(zuo)頻率較低的(de)開(kai)(kai)關式(ON-OFF)的(de)換(huan)向閥(fa)來控(kong)(kong)(kong)(kong)(kong)制氣(qi)路的(de)通斷。靠減(jian)壓(ya)(ya)閥(fa)來調(diao)節所(suo)需(xu)要(yao)的(de)壓(ya)(ya)力(li)(li)，靠節流(liu)(liu)閥(fa)來調(diao)節所(suo)需(xu)要(yao)的(de)流(liu)(liu)量(liang)。這種(zhong)傳統的(de)氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制系統要(yao)想(xiang)要(yao)有(you)多(duo)(duo)(duo)個輸出力(li)(li)和多(duo)(duo)(duo)個運動(dong)速度，就需(xu)要(yao)多(duo)(duo)(duo)個減(jian)壓(ya)(ya)閥(fa)、節流(liu)(liu)閥(fa)及換(huan)向閥(fa)。這樣，不僅元件(jian)需(xu)要(yao)多(duo)(duo)(duo)，成(cheng)本高，構成(cheng)系統復雜，且許(xu)多(duo)(duo)(duo)元件(jian)都(dou)需(xu)要(yao)預先進(jin)行人(ren)工(gong)調(diao)節。電(dian)(dian)氣(qi)比(bi)例(li)(li)閥(fa)控(kong)(kong)(kong)(kong)(kong)制屬于連續控(kong)(kong)(kong)(kong)(kong)制，其特(te)點是輸出量(liang)隨輸入(ru)量(liang)的(de)變化而變化，輸出量(liang)與輸入(ru)量(liang)之間存在一定的(de)比(bi)例(li)(li)關系。比(bi)例(li)(li)控(kong)(kong)(kong)(kong)(kong)制有(you)開(kai)(kai)環(huan)控(kong)(kong)(kong)(kong)(kong)制和閉環(huan)控(kong)(kong)(kong)(kong)(kong)制之分(fen)。 |
