意大利ATOS比例閥特點: - 可實現壓力、速度的(de)無極(ji)調節,避免了常通的(de)開關式(shi)氣(qi)閥換向時的(de)沖擊現象。
- 能(neng)實現遠(yuan)程控制和程序(xu)控制。
- 與斷續控制相比,系統(tong)簡化,元件大大減少(shao)。
- 與液壓比例閥相比,體積(ji)小(xiao)、重量輕、結構簡(jian)單、成本較低,但(dan)響(xiang)應(ying)速度(du)比液壓系(xi)統慢得多,對負載變化也比較敏(min)感。
- 使用功率(lv)小、發熱少、噪聲低。
- 不會發(fa)生火(huo)災,*。受溫(wen)度(du)變化的(de)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。 電氣(qi)(qi)比(bi)例閥(fa)(fa)(fa)(fa)自動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)可分(fen)成(cheng)斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)和連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)即開(kai)關控(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)(qi)動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong)(tong)中使(shi)用動(dong)(dong)作(zuo)頻率較低(di)的(de)開(kai)關式(ON-OFF)的(de)換向閥(fa)(fa)(fa)(fa)來控(kong)(kong)(kong)制(zhi)(zhi)氣(qi)(qi)路的(de)通斷(duan)。靠(kao)減壓閥(fa)(fa)(fa)(fa)來調節(jie)(jie)所(suo)需(xu)要的(de)壓力(li),靠(kao)節(jie)(jie)流(liu)閥(fa)(fa)(fa)(fa)來調節(jie)(jie)所(suo)需(xu)要的(de)流(liu)量(liang)(liang)。這(zhe)種傳統(tong)(tong)的(de)氣(qi)(qi)動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)系統(tong)(tong)要想(xiang)要有(you)多(duo)個(ge)輸(shu)出力(li)和多(duo)個(ge)運動(dong)(dong)速度,就需(xu)要多(duo)個(ge)減壓閥(fa)(fa)(fa)(fa)、節(jie)(jie)流(liu)閥(fa)(fa)(fa)(fa)及換向閥(fa)(fa)(fa)(fa)。這(zhe)樣,不僅元件需(xu)要多(duo),成(cheng)本高,構成(cheng)系統(tong)(tong)復雜,且許多(duo)元件都需(xu)要預先進行人(ren)工調節(jie)(jie)。電氣(qi)(qi)比(bi)例閥(fa)(fa)(fa)(fa)控(kong)(kong)(kong)制(zhi)(zhi)屬于連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi),其特點是輸(shu)出量(liang)(liang)隨輸(shu)入量(liang)(liang)的(de)變化(hua)而變化(hua),輸(shu)出量(liang)(liang)與輸(shu)入量(liang)(liang)之間(jian)存在一定的(de)比(bi)例關系。比(bi)例控(kong)(kong)(kong)制(zhi)(zhi)有(you)開(kai)環(huan)控(kong)(kong)(kong)制(zhi)(zhi)和閉環(huan)控(kong)(kong)(kong)制(zhi)(zhi)之分(fen)。 |
