意大利ATOS比例閥特點： - 可(ke)實現壓力、速度的無極(ji)調節，避(bi)免(mian)了常通的開(kai)關式(shi)氣閥換(huan)向時的沖擊(ji)現象(xiang)。
- 能實(shi)現遠(yuan)程控(kong)(kong)制和程序控(kong)(kong)制。
- 與斷續控制相比，系(xi)統簡化，元件大(da)大(da)減少(shao)。
- 與液壓比(bi)例閥相比(bi)，體積小(xiao)、重量輕、結構簡(jian)單(dan)、成本較低，但響應(ying)速度(du)比(bi)液壓系統慢得(de)多，對負載變(bian)化(hua)也比(bi)較敏感(gan)。
- 使用功率小、發熱少、噪聲低。
- 不(bu)會發(fa)生火災(zai)，*。受溫度變化(hua)的影(ying)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)比例(li)閥(fa)自動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)可分成斷續控(kong)(kong)(kong)制(zhi)(zhi)和(he)連續控(kong)(kong)(kong)制(zhi)(zhi)。斷續控(kong)(kong)(kong)制(zhi)(zhi)即開關(guan)控(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)中使用動(dong)(dong)作頻率較低的(de)(de)開關(guan)式(ON-OFF)的(de)(de)換向閥(fa)來控(kong)(kong)(kong)制(zhi)(zhi)氣(qi)路的(de)(de)通斷。靠(kao)減壓閥(fa)來調節(jie)所需(xu)(xu)要(yao)的(de)(de)壓力，靠(kao)節(jie)流閥(fa)來調節(jie)所需(xu)(xu)要(yao)的(de)(de)流量(liang)。這(zhe)種傳統(tong)(tong)的(de)(de)氣(qi)動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)要(yao)想要(yao)有多(duo)(duo)(duo)個(ge)輸(shu)出力和(he)多(duo)(duo)(duo)個(ge)運動(dong)(dong)速度，就需(xu)(xu)要(yao)多(duo)(duo)(duo)個(ge)減壓閥(fa)、節(jie)流閥(fa)及換向閥(fa)。這(zhe)樣(yang)，不僅元(yuan)件需(xu)(xu)要(yao)多(duo)(duo)(duo)，成本(ben)高，構成系(xi)(xi)(xi)統(tong)(tong)復雜，且許多(duo)(duo)(duo)元(yuan)件都需(xu)(xu)要(yao)預先進行人(ren)工調節(jie)。電(dian)氣(qi)比例(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)屬于連續控(kong)(kong)(kong)制(zhi)(zhi)，其(qi)特點是輸(shu)出量(liang)隨輸(shu)入量(liang)的(de)(de)變(bian)化(hua)而變(bian)化(hua)，輸(shu)出量(liang)與(yu)輸(shu)入量(liang)之間存在一定的(de)(de)比例(li)關(guan)系(xi)(xi)(xi)。比例(li)控(kong)(kong)(kong)制(zhi)(zhi)有開環控(kong)(kong)(kong)制(zhi)(zhi)和(he)閉環控(kong)(kong)(kong)制(zhi)(zhi)之分。 |
