意大利ATOS比例閥特點： - 可實現壓力、速度的無極調(diao)節，避免(mian)了常(chang)通(tong)的開關式氣閥(fa)換向(xiang)時的沖擊(ji)現象。
- 能實現遠(yuan)程控制和程序控制。
- 與斷續控制相比，系(xi)統簡化(hua)，元件大(da)大(da)減少。
- 與液(ye)壓(ya)比例(li)閥相比，體積(ji)小、重量輕、結構(gou)簡單、成本較低，但響應(ying)速度比液(ye)壓(ya)系統(tong)慢得多，對負載變化也比較敏感(gan)。
- 使用功(gong)率小、發熱少、噪(zao)聲低(di)。
- 不會發生火災，*。受溫度變化(hua)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)(dian)氣(qi)比(bi)(bi)(bi)例閥(fa)自動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)可分(fen)成斷(duan)續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)(he)連續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)即(ji)開關(guan)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)中使用動(dong)作頻率較(jiao)低的(de)開關(guan)式(shi)(ON-OFF)的(de)換向閥(fa)來控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)氣(qi)路的(de)通斷(duan)。靠減壓(ya)閥(fa)來調(diao)(diao)節所(suo)需(xu)(xu)要(yao)的(de)壓(ya)力，靠節流閥(fa)來調(diao)(diao)節所(suo)需(xu)(xu)要(yao)的(de)流量(liang)。這種(zhong)傳統(tong)的(de)氣(qi)動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)要(yao)想(xiang)要(yao)有多個輸(shu)(shu)出(chu)力和(he)(he)多個運動(dong)速度，就需(xu)(xu)要(yao)多個減壓(ya)閥(fa)、節流閥(fa)及換向閥(fa)。這樣，不僅元件需(xu)(xu)要(yao)多，成本高，構(gou)成系統(tong)復雜，且許多元件都需(xu)(xu)要(yao)預先進行人工調(diao)(diao)節。電(dian)(dian)氣(qi)比(bi)(bi)(bi)例閥(fa)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于連續(xu)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)，其特點是輸(shu)(shu)出(chu)量(liang)隨(sui)輸(shu)(shu)入(ru)量(liang)的(de)變化而變化，輸(shu)(shu)出(chu)量(liang)與(yu)輸(shu)(shu)入(ru)量(liang)之間(jian)存在(zai)一定的(de)比(bi)(bi)(bi)例關(guan)系。比(bi)(bi)(bi)例控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)有開環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)(he)閉環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)之分(fen)。 |
