ATOS比例閥特點: - 可實現壓力、速度的(de)無(wu)極調(diao)節,避(bi)免了(le)常通(tong)的(de)開關式氣閥換向時的(de)沖(chong)擊現象。
- 能實現遠程控(kong)制和程序(xu)控(kong)制。
- 與斷續控(kong)制相比(bi),系(xi)統(tong)簡(jian)化,元件大(da)大(da)減(jian)少(shao)。
- 與液壓比例(li)閥(fa)相比,體積小、重量輕、結構(gou)簡單(dan)、成本較低(di),但響應速度比液壓系統慢(man)得多(duo),對負(fu)載變化也比較敏感(gan)。
- 使用功率小、發熱少、噪聲低。
- 不(bu)會(hui)發生(sheng)火災(zai),*。受溫度(du)變化的(de)影(ying)響小(xiao)。

ATOS阿托斯比例閥向閥屬于比例閥的一種,用來控制流量和流向。 電氣(qi)比例(li)(li)閥(fa)自(zi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分成斷續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)連續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。斷續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)即開關(guan)(guan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系統(tong)中使用(yong)動(dong)作頻率(lv)較低(di)的(de)開關(guan)(guan)式(ON-OFF)的(de)換(huan)向閥(fa)來控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)氣(qi)路的(de)通斷。靠(kao)減(jian)壓(ya)閥(fa)來調節所需(xu)(xu)要(yao)的(de)壓(ya)力,靠(kao)節流(liu)閥(fa)來調節所需(xu)(xu)要(yao)的(de)流(liu)量(liang)(liang)(liang)。這(zhe)種傳統(tong)的(de)氣(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系統(tong)要(yao)想要(yao)有多個輸出(chu)力和(he)多個運(yun)動(dong)速(su)度,就(jiu)需(xu)(xu)要(yao)多個減(jian)壓(ya)閥(fa)、節流(liu)閥(fa)及換(huan)向閥(fa)。這(zhe)樣,不僅元件(jian)需(xu)(xu)要(yao)多,成本高,構成系統(tong)復雜,且許(xu)多元件(jian)都需(xu)(xu)要(yao)預先(xian)進行(xing)人工調節。電氣(qi)比例(li)(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)屬于連續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi),其特點是(shi)輸出(chu)量(liang)(liang)(liang)隨輸入量(liang)(liang)(liang)的(de)變化而變化,輸出(chu)量(liang)(liang)(liang)與輸入量(liang)(liang)(liang)之(zhi)間存在一(yi)定的(de)比例(li)(li)關(guan)(guan)系。比例(li)(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)有開環(huan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)閉環(huan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)之(zhi)分。 |
