意大利ATOS比例閥特點: - 可實現(xian)壓力、速度的無(wu)極調節,避免了常通的開(kai)關式氣閥換向時的沖(chong)擊(ji)現(xian)象。
- 能實現遠(yuan)程控制(zhi)和程序控制(zhi)。
- 與斷續控(kong)制相比,系統簡化,元件大大減少。
- 與(yu)液(ye)壓比(bi)例閥(fa)相比(bi),體積小、重量輕、結構簡單、成本較(jiao)低,但響應(ying)速度比(bi)液(ye)壓系(xi)統慢得多,對負載變化也比(bi)較(jiao)敏感(gan)。
- 使(shi)用功率小(xiao)、發熱少、噪聲低。
- 不會發(fa)生(sheng)火災,*。受溫度(du)變(bian)化(hua)的影響小(xiao)。

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)例閥自(zi)動控(kong)(kong)制(zhi)可分(fen)成(cheng)斷續(xu)控(kong)(kong)制(zhi)和(he)(he)(he)連(lian)續(xu)控(kong)(kong)制(zhi)。斷續(xu)控(kong)(kong)制(zhi)即開(kai)關控(kong)(kong)制(zhi)。氣(qi)(qi)動控(kong)(kong)制(zhi)系(xi)(xi)統(tong)中使(shi)用動作頻率較低的開(kai)關式(shi)(ON-OFF)的換(huan)向(xiang)閥來(lai)控(kong)(kong)制(zhi)氣(qi)(qi)路的通(tong)斷。靠減壓(ya)閥來(lai)調(diao)(diao)節所需(xu)要(yao)的壓(ya)力,靠節流閥來(lai)調(diao)(diao)節所需(xu)要(yao)的流量(liang)。這(zhe)種傳統(tong)的氣(qi)(qi)動控(kong)(kong)制(zhi)系(xi)(xi)統(tong)要(yao)想(xiang)要(yao)有(you)多個(ge)輸出(chu)力和(he)(he)(he)多個(ge)運動速(su)度,就需(xu)要(yao)多個(ge)減壓(ya)閥、節流閥及換(huan)向(xiang)閥。這(zhe)樣,不僅元件需(xu)要(yao)多,成(cheng)本(ben)高,構(gou)成(cheng)系(xi)(xi)統(tong)復(fu)雜(za),且許(xu)多元件都需(xu)要(yao)預先進行人工調(diao)(diao)節。電(dian)氣(qi)(qi)比(bi)(bi)例閥控(kong)(kong)制(zhi)屬于連(lian)續(xu)控(kong)(kong)制(zhi),其特點是輸出(chu)量(liang)隨輸入量(liang)的變化而變化,輸出(chu)量(liang)與輸入量(liang)之(zhi)間存在一定的比(bi)(bi)例關系(xi)(xi)。比(bi)(bi)例控(kong)(kong)制(zhi)有(you)開(kai)環控(kong)(kong)制(zhi)和(he)(he)(he)閉環控(kong)(kong)制(zhi)之(zhi)分(fen)。 |
