意大利ATOS比例閥特點： - 可實現(xian)壓力、速度(du)的無極調(diao)節(jie)，避免了常(chang)通的開(kai)關式(shi)氣(qi)閥換向時的沖擊現(xian)象。
- 能實現遠程控制和程序控制。
- 與斷續控制相(xiang)比，系統簡化，元件大大減少。
- 與液壓比(bi)例閥相比(bi)，體(ti)積小、重量(liang)輕、結構簡單、成本較低，但響應速度比(bi)液壓系統慢(man)得多，對(dui)負載變(bian)化也比(bi)較敏感。
- 使(shi)用功(gong)率小、發熱少、噪聲低。
- 不會發生(sheng)火災(zai)，*。受溫(wen)度變化的影響(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)(qi)(qi)比(bi)例(li)閥(fa)(fa)自動(dong)控(kong)(kong)(kong)(kong)制(zhi)可分成斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)和連(lian)續(xu)控(kong)(kong)(kong)(kong)制(zhi)。斷續(xu)控(kong)(kong)(kong)(kong)制(zhi)即開關控(kong)(kong)(kong)(kong)制(zhi)。氣(qi)(qi)(qi)(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)統中使(shi)用動(dong)作頻率較低(di)的開關式(ON-OFF)的換(huan)(huan)向閥(fa)(fa)來控(kong)(kong)(kong)(kong)制(zhi)氣(qi)(qi)(qi)(qi)路的通(tong)斷。靠減(jian)壓(ya)閥(fa)(fa)來調(diao)(diao)節(jie)(jie)(jie)所(suo)需(xu)要的壓(ya)力，靠節(jie)(jie)(jie)流閥(fa)(fa)來調(diao)(diao)節(jie)(jie)(jie)所(suo)需(xu)要的流量(liang)。這種傳統的氣(qi)(qi)(qi)(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)系(xi)統要想要有多個(ge)(ge)輸出力和多個(ge)(ge)運動(dong)速(su)度，就(jiu)需(xu)要多個(ge)(ge)減(jian)壓(ya)閥(fa)(fa)、節(jie)(jie)(jie)流閥(fa)(fa)及(ji)換(huan)(huan)向閥(fa)(fa)。這樣，不僅元(yuan)(yuan)件需(xu)要多，成本(ben)高，構成系(xi)統復雜(za)，且許多元(yuan)(yuan)件都需(xu)要預先進行人(ren)工調(diao)(diao)節(jie)(jie)(jie)。電氣(qi)(qi)(qi)(qi)比(bi)例(li)閥(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)屬于(yu)連(lian)續(xu)控(kong)(kong)(kong)(kong)制(zhi)，其特點(dian)是輸出量(liang)隨輸入(ru)量(liang)的變(bian)化(hua)而變(bian)化(hua)，輸出量(liang)與輸入(ru)量(liang)之間存在一(yi)定的比(bi)例(li)關系(xi)。比(bi)例(li)控(kong)(kong)(kong)(kong)制(zhi)有開環控(kong)(kong)(kong)(kong)制(zhi)和閉環控(kong)(kong)(kong)(kong)制(zhi)之分。 |
