意大利ATOS比例閥特點： - 可實現壓力、速度的(de)(de)無極(ji)調節，避免了常通的(de)(de)開關式氣閥換向(xiang)時(shi)的(de)(de)沖擊現象。
- 能實現遠程(cheng)控制和程(cheng)序控制。
- 與斷(duan)續控制(zhi)相比，系統(tong)簡(jian)化，元件大大減少。
- 與液(ye)壓比(bi)例閥相比(bi)，體積小、重量輕、結(jie)構簡(jian)單、成本較(jiao)低，但響應速度(du)比(bi)液(ye)壓系統慢得多(duo)，對負載(zai)變化也(ye)比(bi)較(jiao)敏感。
- 使用功(gong)率小、發熱少、噪(zao)聲(sheng)低。
- 不會發生(sheng)火災，*。受溫(wen)度變化的影響小(xiao)。

LIQZO-TES-PS-162L4 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。 電氣比例閥(fa)自動(dong)(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)可分成斷續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)連續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。斷續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)即開(kai)關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。氣動(dong)(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)(tong)中使用(yong)動(dong)(dong)(dong)作頻(pin)率較(jiao)低的(de)(de)開(kai)關(guan)式(shi)(ON-OFF)的(de)(de)換(huan)向閥(fa)來控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)氣路(lu)的(de)(de)通斷。靠減壓閥(fa)來調(diao)節(jie)所需(xu)要(yao)(yao)的(de)(de)壓力，靠節(jie)流(liu)閥(fa)來調(diao)節(jie)所需(xu)要(yao)(yao)的(de)(de)流(liu)量。這種(zhong)傳統(tong)(tong)的(de)(de)氣動(dong)(dong)(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)系(xi)統(tong)(tong)要(yao)(yao)想要(yao)(yao)有(you)多(duo)(duo)個輸出(chu)力和(he)多(duo)(duo)個運(yun)動(dong)(dong)(dong)速度，就需(xu)要(yao)(yao)多(duo)(duo)個減壓閥(fa)、節(jie)流(liu)閥(fa)及換(huan)向閥(fa)。這樣，不僅元件需(xu)要(yao)(yao)多(duo)(duo)，成本高(gao)，構成系(xi)統(tong)(tong)復雜(za)，且許多(duo)(duo)元件都需(xu)要(yao)(yao)預先進(jin)行人工調(diao)節(jie)。電氣比例閥(fa)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)屬于連續控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)，其特(te)點是輸出(chu)量隨輸入量的(de)(de)變化而變化，輸出(chu)量與輸入量之間存在一定的(de)(de)比例關(guan)系(xi)。比例控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)有(you)開(kai)環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)閉環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)之分。 |
