意大利ATOS比例閥特點： - 可實現(xian)壓力、速度(du)的無極調節(jie)，避免(mian)了常通的開關式(shi)氣閥(fa)換向時(shi)的沖(chong)擊現(xian)象。
- 能實現(xian)遠程控制和(he)程序控制。
- 與(yu)斷續控制相比，系統簡化，元件大(da)大(da)減少。
- 與液壓比例閥(fa)相比，體積小、重量輕、結構簡單、成本較低，但響應速(su)度(du)比液壓系統(tong)慢得多(duo)，對(dui)負(fu)載變化也(ye)比較敏感。
- 使用功率(lv)小、發熱少、噪聲低。
- 不(bu)會發(fa)生火(huo)災，*。受溫度變化(hua)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)比(bi)例(li)閥(fa)自動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)可分成(cheng)斷(duan)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)連(lian)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。斷(duan)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)即開關(guan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系統中使用動(dong)作頻率較低(di)的(de)(de)開關(guan)式(ON-OFF)的(de)(de)換向閥(fa)來控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)氣(qi)路(lu)的(de)(de)通斷(duan)。靠減壓閥(fa)來調(diao)節(jie)(jie)所需(xu)要(yao)(yao)的(de)(de)壓力，靠節(jie)(jie)流閥(fa)來調(diao)節(jie)(jie)所需(xu)要(yao)(yao)的(de)(de)流量(liang)(liang)。這種傳統的(de)(de)氣(qi)動(dong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系統要(yao)(yao)想要(yao)(yao)有多個(ge)(ge)輸出力和(he)多個(ge)(ge)運動(dong)速度，就需(xu)要(yao)(yao)多個(ge)(ge)減壓閥(fa)、節(jie)(jie)流閥(fa)及換向閥(fa)。這樣，不僅元件(jian)(jian)需(xu)要(yao)(yao)多，成(cheng)本高，構成(cheng)系統復雜(za)，且(qie)許(xu)多元件(jian)(jian)都(dou)需(xu)要(yao)(yao)預先進行人工調(diao)節(jie)(jie)。電氣(qi)比(bi)例(li)閥(fa)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)屬于連(lian)續(xu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)，其特點是輸出量(liang)(liang)隨輸入量(liang)(liang)的(de)(de)變(bian)化而變(bian)化，輸出量(liang)(liang)與輸入量(liang)(liang)之間(jian)存在(zai)一定的(de)(de)比(bi)例(li)關(guan)系。比(bi)例(li)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)有開環(huan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)閉環(huan)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)之分。 |
