意大利ATOS比例閥特點: - 可(ke)實現壓力、速度的(de)(de)無極調節,避免了常通的(de)(de)開關(guan)式氣閥(fa)換向時的(de)(de)沖擊(ji)現象。
- 能(neng)實現遠程控制和(he)程序控制。
- 與(yu)斷續(xu)控制相比,系統簡化,元(yuan)件(jian)大大減少(shao)。
- 與液壓(ya)比(bi)例閥(fa)相比(bi),體積小(xiao)、重(zhong)量輕、結構簡(jian)單、成(cheng)本(ben)較低,但響應速(su)度比(bi)液壓(ya)系統(tong)慢得多,對負載(zai)變化也(ye)比(bi)較敏感。
- 使用(yong)功率小、發熱(re)少、噪聲(sheng)低。
- 不會發生火(huo)災(zai),*。受溫度變化的(de)影(ying)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。 電氣比例(li)閥(fa)自動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)可分(fen)成(cheng)斷續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和連(lian)續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷續控(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開(kai)關(guan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統中使(shi)用(yong)動作頻率較低的(de)開(kai)關(guan)式(ON-OFF)的(de)換(huan)向閥(fa)來控(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣路的(de)通斷。靠(kao)減壓(ya)(ya)閥(fa)來調(diao)節(jie)(jie)所(suo)需要(yao)的(de)壓(ya)(ya)力(li),靠(kao)節(jie)(jie)流(liu)(liu)(liu)閥(fa)來調(diao)節(jie)(jie)所(suo)需要(yao)的(de)流(liu)(liu)(liu)量(liang)。這種(zhong)傳統的(de)氣動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統要(yao)想要(yao)有多(duo)(duo)個輸(shu)出力(li)和多(duo)(duo)個運動速度,就需要(yao)多(duo)(duo)個減壓(ya)(ya)閥(fa)、節(jie)(jie)流(liu)(liu)(liu)閥(fa)及換(huan)向閥(fa)。這樣,不(bu)僅元(yuan)件需要(yao)多(duo)(duo),成(cheng)本(ben)高,構成(cheng)系(xi)統復雜,且許多(duo)(duo)元(yuan)件都需要(yao)預先進行(xing)人工調(diao)節(jie)(jie)。電氣比例(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬于連(lian)續控(kong)(kong)(kong)制(zhi)(zhi)(zhi),其特點(dian)是輸(shu)出量(liang)隨(sui)輸(shu)入(ru)量(liang)的(de)變化(hua)而變化(hua),輸(shu)出量(liang)與輸(shu)入(ru)量(liang)之間存(cun)在一定的(de)比例(li)關(guan)系(xi)。比例(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開(kai)環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和閉環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)之分(fen)。 |
