意大利ATOS比例閥特點: - 可實現(xian)壓(ya)力(li)、速(su)度的(de)(de)無極調節,避免(mian)了常(chang)通的(de)(de)開(kai)關式氣(qi)閥換向(xiang)時的(de)(de)沖擊(ji)現(xian)象。
- 能實(shi)現遠程(cheng)控制(zhi)和程(cheng)序控制(zhi)。
- 與(yu)斷續(xu)控制(zhi)相比(bi),系(xi)統簡(jian)化,元件大大減少。
- 與液壓(ya)(ya)比例閥(fa)相比,體積(ji)小(xiao)、重(zhong)量輕、結(jie)構(gou)簡單(dan)、成(cheng)本較低,但響(xiang)應(ying)速度比液壓(ya)(ya)系統慢得(de)多,對負(fu)載(zai)變化也(ye)比較敏感。
- 使用功率小、發熱少、噪聲低。
- 不會發(fa)生火災,*。受溫度變(bian)化的影響小。

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)比例(li)閥(fa)(fa)(fa)自動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)可分成(cheng)斷續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)連續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開(kai)關控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣(qi)(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)(tong)中使用動(dong)作頻率較低的(de)(de)(de)(de)開(kai)關式(ON-OFF)的(de)(de)(de)(de)換(huan)向(xiang)(xiang)閥(fa)(fa)(fa)來(lai)(lai)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣(qi)(qi)路的(de)(de)(de)(de)通斷。靠(kao)減壓(ya)閥(fa)(fa)(fa)來(lai)(lai)調(diao)節(jie)所(suo)需要的(de)(de)(de)(de)壓(ya)力(li),靠(kao)節(jie)流閥(fa)(fa)(fa)來(lai)(lai)調(diao)節(jie)所(suo)需要的(de)(de)(de)(de)流量(liang)。這種傳統(tong)(tong)的(de)(de)(de)(de)氣(qi)(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系統(tong)(tong)要想要有多(duo)個輸出力(li)和(he)多(duo)個運動(dong)速度,就需要多(duo)個減壓(ya)閥(fa)(fa)(fa)、節(jie)流閥(fa)(fa)(fa)及換(huan)向(xiang)(xiang)閥(fa)(fa)(fa)。這樣,不僅元(yuan)件需要多(duo),成(cheng)本(ben)高,構成(cheng)系統(tong)(tong)復雜,且許(xu)多(duo)元(yuan)件都(dou)需要預(yu)先(xian)進行人工調(diao)節(jie)。電氣(qi)(qi)比例(li)閥(fa)(fa)(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬(shu)于連續控(kong)(kong)(kong)制(zhi)(zhi)(zhi),其特(te)點(dian)是輸出量(liang)隨輸入量(liang)的(de)(de)(de)(de)變化(hua)而變化(hua),輸出量(liang)與輸入量(liang)之間存在一定的(de)(de)(de)(de)比例(li)關系。比例(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開(kai)環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和(he)閉環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)之分。 |
