意大利ATOS比例閥特點： - 可(ke)實(shi)現壓力、速度的無極調節，避(bi)免了常通的開關式氣閥換向時的沖擊現象。
- 能實(shi)現遠程控(kong)制和程序控(kong)制。
- 與斷續控制相比，系統簡(jian)化，元件大大減少(shao)。
- 與液壓比例閥相比，體積小、重量輕、結構簡單、成本較低，但響應速(su)度比液壓系(xi)統慢(man)得(de)多，對負載變化也比較敏(min)感。
- 使用(yong)功率小、發熱少(shao)、噪聲(sheng)低(di)。
- 不會發生火災(zai)，*。受溫度(du)變化的影響小。

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(dian)氣比(bi)(bi)例閥(fa)自動控(kong)(kong)(kong)(kong)制(zhi)(zhi)可分成(cheng)斷(duan)(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)和連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)(duan)續控(kong)(kong)(kong)(kong)制(zhi)(zhi)即開關(guan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣動控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)中(zhong)使用動作頻率(lv)較低(di)的(de)(de)開關(guan)式(ON-OFF)的(de)(de)換向(xiang)閥(fa)來(lai)控(kong)(kong)(kong)(kong)制(zhi)(zhi)氣路的(de)(de)通斷(duan)(duan)。靠減壓(ya)閥(fa)來(lai)調節(jie)(jie)所(suo)需要(yao)的(de)(de)壓(ya)力，靠節(jie)(jie)流(liu)閥(fa)來(lai)調節(jie)(jie)所(suo)需要(yao)的(de)(de)流(liu)量(liang)。這(zhe)種傳統(tong)的(de)(de)氣動控(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)要(yao)想要(yao)有(you)(you)多(duo)個輸出(chu)力和多(duo)個運動速度，就需要(yao)多(duo)個減壓(ya)閥(fa)、節(jie)(jie)流(liu)閥(fa)及換向(xiang)閥(fa)。這(zhe)樣，不僅元件需要(yao)多(duo)，成(cheng)本高，構成(cheng)系統(tong)復雜，且許多(duo)元件都需要(yao)預先進(jin)行人工調節(jie)(jie)。電(dian)氣比(bi)(bi)例閥(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于(yu)連續控(kong)(kong)(kong)(kong)制(zhi)(zhi)，其特(te)點是(shi)輸出(chu)量(liang)隨輸入(ru)量(liang)的(de)(de)變化(hua)而(er)變化(hua)，輸出(chu)量(liang)與(yu)輸入(ru)量(liang)之(zhi)間存在一定(ding)的(de)(de)比(bi)(bi)例關(guan)系。比(bi)(bi)例控(kong)(kong)(kong)(kong)制(zhi)(zhi)有(you)(you)開環(huan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)和閉(bi)環(huan)控(kong)(kong)(kong)(kong)制(zhi)(zhi)之(zhi)分。 |
