意大利ATOS比例閥特點： - 可實現(xian)壓力(li)、速度的無(wu)極調節，避免了常通(tong)的開關(guan)式(shi)氣閥(fa)換向(xiang)時的沖(chong)擊現(xian)象(xiang)。
- 能實(shi)現遠程控制(zhi)和程序控制(zhi)。
- 與(yu)斷續控制相比，系統簡化(hua)，元件大(da)大(da)減少。
- 與液(ye)壓(ya)比例閥相(xiang)比，體積(ji)小、重量輕、結構簡單、成(cheng)本較低，但響應速(su)度比液(ye)壓(ya)系統慢得多，對(dui)負載變化也比較敏感。
- 使用功率小(xiao)、發熱少、噪聲低(di)。
- 不會發生火(huo)災(zai)，*。受溫度變(bian)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)氣比例(li)(li)閥自動(dong)控(kong)(kong)(kong)(kong)制(zhi)可分成(cheng)斷(duan)續(xu)控(kong)(kong)(kong)(kong)制(zhi)和(he)連續(xu)控(kong)(kong)(kong)(kong)制(zhi)。斷(duan)續(xu)控(kong)(kong)(kong)(kong)制(zhi)即開(kai)關控(kong)(kong)(kong)(kong)制(zhi)。氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)(xi)統(tong)中使用動(dong)作(zuo)頻率較(jiao)低的(de)(de)開(kai)關式(shi)(ON-OFF)的(de)(de)換向閥來控(kong)(kong)(kong)(kong)制(zhi)氣路的(de)(de)通斷(duan)。靠(kao)(kao)減壓閥來調節(jie)(jie)所需(xu)要(yao)的(de)(de)壓力，靠(kao)(kao)節(jie)(jie)流(liu)閥來調節(jie)(jie)所需(xu)要(yao)的(de)(de)流(liu)量。這(zhe)種(zhong)傳統(tong)的(de)(de)氣動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)(xi)統(tong)要(yao)想要(yao)有多(duo)個輸(shu)出力和(he)多(duo)個運動(dong)速度，就需(xu)要(yao)多(duo)個減壓閥、節(jie)(jie)流(liu)閥及(ji)換向閥。這(zhe)樣，不僅(jin)元件需(xu)要(yao)多(duo)，成(cheng)本(ben)高，構成(cheng)系(xi)(xi)統(tong)復雜，且許多(duo)元件都需(xu)要(yao)預先進行人工調節(jie)(jie)。電(dian)氣比例(li)(li)閥控(kong)(kong)(kong)(kong)制(zhi)屬于連續(xu)控(kong)(kong)(kong)(kong)制(zhi)，其特點是輸(shu)出量隨輸(shu)入量的(de)(de)變化(hua)而(er)變化(hua)，輸(shu)出量與(yu)輸(shu)入量之間(jian)存(cun)在(zai)一定的(de)(de)比例(li)(li)關系(xi)(xi)。比例(li)(li)控(kong)(kong)(kong)(kong)制(zhi)有開(kai)環控(kong)(kong)(kong)(kong)制(zhi)和(he)閉環控(kong)(kong)(kong)(kong)制(zhi)之分。 |
