意大利ATOS比例閥特點： - 可實現壓力、速度的無極調節，避免了常(chang)通的開關式氣(qi)閥換(huan)向時的沖擊現象(xiang)。
- 能實現遠程(cheng)控制和(he)程(cheng)序控制。
- 與(yu)斷(duan)續控制相比，系統(tong)簡化，元件大大減少。
- 與液壓比(bi)例(li)閥相比(bi)，體積小、重量(liang)輕、結構簡單(dan)、成本較低(di)，但響應速度比(bi)液壓系統慢得多，對負載變化也比(bi)較敏(min)感。
- 使用功率(lv)小、發熱少、噪聲低。
- 不會發(fa)生火災，*。受溫度變化的影響小。

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(qi)(qi)比(bi)(bi)例(li)(li)(li)閥自動(dong)(dong)控(kong)(kong)制可分成(cheng)斷續控(kong)(kong)制和(he)(he)連(lian)續控(kong)(kong)制。斷續控(kong)(kong)制即(ji)開(kai)關控(kong)(kong)制。氣(qi)(qi)動(dong)(dong)控(kong)(kong)制系(xi)統(tong)(tong)中(zhong)使用動(dong)(dong)作頻率較低的開(kai)關式(ON-OFF)的換(huan)向閥來(lai)控(kong)(kong)制氣(qi)(qi)路的通斷。靠減壓閥來(lai)調節(jie)所(suo)需要(yao)(yao)(yao)的壓力(li)，靠節(jie)流(liu)(liu)閥來(lai)調節(jie)所(suo)需要(yao)(yao)(yao)的流(liu)(liu)量(liang)(liang)(liang)。這種傳(chuan)統(tong)(tong)的氣(qi)(qi)動(dong)(dong)控(kong)(kong)制系(xi)統(tong)(tong)要(yao)(yao)(yao)想要(yao)(yao)(yao)有多(duo)個(ge)(ge)輸(shu)出力(li)和(he)(he)多(duo)個(ge)(ge)運(yun)動(dong)(dong)速度，就需要(yao)(yao)(yao)多(duo)個(ge)(ge)減壓閥、節(jie)流(liu)(liu)閥及換(huan)向閥。這樣，不僅元件需要(yao)(yao)(yao)多(duo)，成(cheng)本高，構成(cheng)系(xi)統(tong)(tong)復(fu)雜，且(qie)許多(duo)元件都需要(yao)(yao)(yao)預先進(jin)行人工調節(jie)。電(dian)氣(qi)(qi)比(bi)(bi)例(li)(li)(li)閥控(kong)(kong)制屬(shu)于連(lian)續控(kong)(kong)制，其(qi)特點是輸(shu)出量(liang)(liang)(liang)隨輸(shu)入量(liang)(liang)(liang)的變(bian)化而(er)變(bian)化，輸(shu)出量(liang)(liang)(liang)與輸(shu)入量(liang)(liang)(liang)之(zhi)間存在(zai)一(yi)定的比(bi)(bi)例(li)(li)(li)關系(xi)。比(bi)(bi)例(li)(li)(li)控(kong)(kong)制有開(kai)環控(kong)(kong)制和(he)(he)閉環控(kong)(kong)制之(zhi)分。 |
