意大利ATOS比例閥特點： - 可實現壓力、速度的無(wu)極(ji)調(diao)節，避免了常通(tong)的開關(guan)式(shi)氣閥換向時的沖擊現象(xiang)。
- 能實現遠程控(kong)制和(he)程序控(kong)制。
- 與(yu)斷續(xu)控制(zhi)相比，系統簡化(hua)，元件大大減少。
- 與液(ye)(ye)壓比例閥相比，體積小、重量(liang)輕、結(jie)構簡(jian)單、成(cheng)本較低，但響應速(su)度比液(ye)(ye)壓系統慢得多，對負載(zai)變化也比較敏感。
- 使用功(gong)率小、發(fa)熱少、噪(zao)聲低。
- 不會發生火災，*。受溫度變(bian)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(qi)(qi)比(bi)例閥(fa)自動控(kong)(kong)(kong)制(zhi)可分成(cheng)斷續(xu)控(kong)(kong)(kong)制(zhi)和連續(xu)控(kong)(kong)(kong)制(zhi)。斷續(xu)控(kong)(kong)(kong)制(zhi)即開關(guan)控(kong)(kong)(kong)制(zhi)。氣(qi)(qi)動控(kong)(kong)(kong)制(zhi)系(xi)統(tong)(tong)中(zhong)使(shi)用(yong)動作頻(pin)率較低的開關(guan)式(shi)(ON-OFF)的換(huan)(huan)向(xiang)閥(fa)來控(kong)(kong)(kong)制(zhi)氣(qi)(qi)路的通斷。靠(kao)減(jian)壓閥(fa)來調(diao)(diao)節(jie)所需(xu)(xu)要(yao)的壓力，靠(kao)節(jie)流閥(fa)來調(diao)(diao)節(jie)所需(xu)(xu)要(yao)的流量(liang)。這(zhe)種(zhong)傳統(tong)(tong)的氣(qi)(qi)動控(kong)(kong)(kong)制(zhi)系(xi)統(tong)(tong)要(yao)想(xiang)要(yao)有(you)多(duo)個輸(shu)(shu)出力和多(duo)個運(yun)動速度，就需(xu)(xu)要(yao)多(duo)個減(jian)壓閥(fa)、節(jie)流閥(fa)及換(huan)(huan)向(xiang)閥(fa)。這(zhe)樣，不僅元(yuan)件(jian)需(xu)(xu)要(yao)多(duo)，成(cheng)本高，構成(cheng)系(xi)統(tong)(tong)復雜，且許多(duo)元(yuan)件(jian)都需(xu)(xu)要(yao)預先進行人工調(diao)(diao)節(jie)。電氣(qi)(qi)比(bi)例閥(fa)控(kong)(kong)(kong)制(zhi)屬(shu)于(yu)連續(xu)控(kong)(kong)(kong)制(zhi)，其特點是輸(shu)(shu)出量(liang)隨輸(shu)(shu)入(ru)量(liang)的變(bian)化而變(bian)化，輸(shu)(shu)出量(liang)與輸(shu)(shu)入(ru)量(liang)之(zhi)間存在一(yi)定的比(bi)例關(guan)系(xi)。比(bi)例控(kong)(kong)(kong)制(zhi)有(you)開環控(kong)(kong)(kong)制(zhi)和閉環控(kong)(kong)(kong)制(zhi)之(zhi)分。 |
