意大利ATOS比例閥特點： - 可實現壓力、速度的無極調節，避免了(le)常通的開關式氣閥換向時的沖(chong)擊現象。
- 能實(shi)現(xian)遠程控制(zhi)和(he)程序控制(zhi)。
- 與斷續控制相(xiang)比，系統(tong)簡化，元件大(da)大(da)減少(shao)。
- 與液壓比(bi)例閥相比(bi)，體積小、重量輕、結構簡(jian)單、成本較(jiao)低，但響應速(su)度(du)比(bi)液壓系統慢得(de)多(duo)，對負載變(bian)化(hua)也比(bi)較(jiao)敏感。
- 使用功率小、發(fa)熱(re)少、噪聲低。
- 不(bu)會發生火災，*。受溫度(du)變化的影響(xiang)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(bi)例(li)(li)(li)閥(fa)自動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分成(cheng)(cheng)斷(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。斷(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)即(ji)開關(guan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系統中使用動(dong)作頻率較低的(de)開關(guan)式(ON-OFF)的(de)換向(xiang)閥(fa)來(lai)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)氣路的(de)通(tong)斷(duan)。靠減(jian)壓閥(fa)來(lai)調(diao)節(jie)所需要(yao)(yao)的(de)壓力(li)(li)，靠節(jie)流閥(fa)來(lai)調(diao)節(jie)所需要(yao)(yao)的(de)流量(liang)(liang)。這(zhe)種傳統的(de)氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系統要(yao)(yao)想要(yao)(yao)有多個輸(shu)出(chu)力(li)(li)和多個運(yun)動(dong)速度，就需要(yao)(yao)多個減(jian)壓閥(fa)、節(jie)流閥(fa)及換向(xiang)閥(fa)。這(zhe)樣(yang)，不(bu)僅元件(jian)(jian)需要(yao)(yao)多，成(cheng)(cheng)本高，構成(cheng)(cheng)系統復雜(za)，且許多元件(jian)(jian)都需要(yao)(yao)預先進行人工調(diao)節(jie)。電氣比(bi)例(li)(li)(li)閥(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)，其特(te)點是輸(shu)出(chu)量(liang)(liang)隨輸(shu)入(ru)量(liang)(liang)的(de)變(bian)化而變(bian)化，輸(shu)出(chu)量(liang)(liang)與輸(shu)入(ru)量(liang)(liang)之間存(cun)在一定的(de)比(bi)例(li)(li)(li)關(guan)系。比(bi)例(li)(li)(li)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)有開環(huan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和閉環(huan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)之分。 |
