意大利ATOS比例閥特點： - 可實現(xian)(xian)壓(ya)力、速度的無極調節，避免(mian)了常通的開關式(shi)氣閥換向時的沖擊(ji)現(xian)(xian)象(xiang)。
- 能實現遠(yuan)程控制(zhi)和程序控制(zhi)。
- 與斷續(xu)控制相比，系統簡化(hua)，元件大大減少。
- 與液(ye)壓比例閥相比，體積小、重量輕、結(jie)構簡(jian)單(dan)、成(cheng)本(ben)較低，但響應速度比液(ye)壓系統(tong)慢(man)得多(duo)，對負載變化也比較敏感。
- 使用功率小、發(fa)熱(re)少、噪聲低。
- 不會發生(sheng)火(huo)災，*。受溫度變化的(de)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。 電氣(qi)(qi)比(bi)例(li)閥(fa)自動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)可分成(cheng)斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。斷(duan)續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)即開(kai)關(guan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)。氣(qi)(qi)動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)(tong)中使(shi)用動作頻(pin)率較低的(de)(de)開(kai)關(guan)式(ON-OFF)的(de)(de)換(huan)向閥(fa)來控(kong)(kong)(kong)制(zhi)(zhi)(zhi)氣(qi)(qi)路(lu)的(de)(de)通斷(duan)。靠減壓閥(fa)來調節(jie)所(suo)需要(yao)的(de)(de)壓力，靠節(jie)流閥(fa)來調節(jie)所(suo)需要(yao)的(de)(de)流量。這種傳(chuan)統(tong)(tong)的(de)(de)氣(qi)(qi)動控(kong)(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)(tong)要(yao)想要(yao)有多(duo)個(ge)輸(shu)(shu)出力和多(duo)個(ge)運動速度，就需要(yao)多(duo)個(ge)減壓閥(fa)、節(jie)流閥(fa)及(ji)換(huan)向閥(fa)。這樣，不僅元(yuan)件(jian)需要(yao)多(duo)，成(cheng)本高(gao)，構成(cheng)系(xi)統(tong)(tong)復雜，且(qie)許(xu)多(duo)元(yuan)件(jian)都需要(yao)預先進行人工調節(jie)。電氣(qi)(qi)比(bi)例(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)屬于連續(xu)(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)，其特點是輸(shu)(shu)出量隨(sui)輸(shu)(shu)入量的(de)(de)變化而變化，輸(shu)(shu)出量與輸(shu)(shu)入量之(zhi)間存在一定的(de)(de)比(bi)例(li)關(guan)系(xi)。比(bi)例(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)有開(kai)環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)和閉(bi)環控(kong)(kong)(kong)制(zhi)(zhi)(zhi)之(zhi)分。 |
