意大利ATOS比例閥特點： - 可實現(xian)壓力、速(su)度的無極(ji)調(diao)節，避免了常通的開關式氣(qi)閥(fa)換(huan)向(xiang)時的沖擊現(xian)象。
- 能實現遠程(cheng)控(kong)制(zhi)和程(cheng)序(xu)控(kong)制(zhi)。
- 與斷(duan)續控制相比，系(xi)統簡化，元件大大減(jian)少。
- 與(yu)液壓比例閥相(xiang)比，體積小、重(zhong)量輕(qing)、結構簡單(dan)、成本(ben)較低，但響(xiang)應(ying)速度比液壓系(xi)統(tong)慢得(de)多，對負載變化也比較敏(min)感(gan)。
- 使用功率小、發熱少、噪聲低(di)。
- 不會發生火災(zai)，*。受溫度(du)變化的(de)影(ying)響小。

DKZOR-TE-171-S5 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)氣(qi)(qi)比(bi)(bi)例(li)閥(fa)自動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)可分成(cheng)(cheng)斷(duan)續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)連續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)即(ji)開(kai)(kai)關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)(qi)動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)(xi)統中(zhong)使用動(dong)(dong)作頻率較低的開(kai)(kai)關(guan)式(ON-OFF)的換(huan)向(xiang)閥(fa)來(lai)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)氣(qi)(qi)路的通(tong)斷(duan)。靠減壓閥(fa)來(lai)調(diao)節(jie)所需(xu)要(yao)(yao)的壓力(li)，靠節(jie)流(liu)閥(fa)來(lai)調(diao)節(jie)所需(xu)要(yao)(yao)的流(liu)量。這種傳統的氣(qi)(qi)動(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)(xi)統要(yao)(yao)想要(yao)(yao)有(you)多個輸出(chu)力(li)和(he)多個運動(dong)(dong)速度(du)，就需(xu)要(yao)(yao)多個減壓閥(fa)、節(jie)流(liu)閥(fa)及換(huan)向(xiang)閥(fa)。這樣，不僅元(yuan)件需(xu)要(yao)(yao)多，成(cheng)(cheng)本高，構成(cheng)(cheng)系(xi)(xi)統復雜(za)，且許多元(yuan)件都需(xu)要(yao)(yao)預先進(jin)行人工調(diao)節(jie)。電(dian)氣(qi)(qi)比(bi)(bi)例(li)閥(fa)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，其特點是輸出(chu)量隨輸入量的變(bian)化而變(bian)化，輸出(chu)量與輸入量之(zhi)間(jian)存在(zai)一(yi)定(ding)的比(bi)(bi)例(li)關(guan)系(xi)(xi)。比(bi)(bi)例(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)有(you)開(kai)(kai)環(huan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)閉環(huan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)之(zhi)分。 |
