意大利ATOS比例閥特點: - 可實現(xian)壓(ya)力(li)、速(su)度的(de)(de)無極調(diao)節(jie),避免了(le)常通的(de)(de)開關(guan)式氣閥換(huan)向(xiang)時的(de)(de)沖擊現(xian)象。
- 能實(shi)現遠程(cheng)控制(zhi)(zhi)和程(cheng)序(xu)控制(zhi)(zhi)。
- 與斷續(xu)控制相比,系統簡化(hua),元件(jian)大大減少(shao)。
- 與液壓(ya)比例(li)閥(fa)相比,體積小、重量輕、結構簡(jian)單、成(cheng)本較(jiao)低,但響(xiang)應速度比液壓(ya)系統慢得多,對負(fu)載(zai)變化也比較(jiao)敏感(gan)。
- 使用功率小、發熱少、噪聲低。
- 不(bu)會發(fa)生火災,*。受(shou)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。 電氣(qi)比例(li)閥(fa)(fa)自動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)可分成斷(duan)(duan)(duan)續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)連續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。斷(duan)(duan)(duan)續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)即開(kai)關控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。氣(qi)動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統中使用動作頻(pin)率較(jiao)低的(de)開(kai)關式(ON-OFF)的(de)換(huan)向(xiang)閥(fa)(fa)來(lai)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)氣(qi)路的(de)通斷(duan)(duan)(duan)。靠減壓閥(fa)(fa)來(lai)調節所(suo)需(xu)(xu)(xu)要(yao)(yao)(yao)的(de)壓力(li),靠節流閥(fa)(fa)來(lai)調節所(suo)需(xu)(xu)(xu)要(yao)(yao)(yao)的(de)流量。這(zhe)種傳(chuan)統的(de)氣(qi)動控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)系(xi)(xi)統要(yao)(yao)(yao)想要(yao)(yao)(yao)有(you)多(duo)(duo)個輸(shu)出力(li)和(he)多(duo)(duo)個運動速(su)度,就需(xu)(xu)(xu)要(yao)(yao)(yao)多(duo)(duo)個減壓閥(fa)(fa)、節流閥(fa)(fa)及(ji)換(huan)向(xiang)閥(fa)(fa)。這(zhe)樣,不僅(jin)元件需(xu)(xu)(xu)要(yao)(yao)(yao)多(duo)(duo),成本高,構成系(xi)(xi)統復雜,且許多(duo)(duo)元件都(dou)需(xu)(xu)(xu)要(yao)(yao)(yao)預(yu)先進行(xing)人工調節。電氣(qi)比例(li)閥(fa)(fa)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)屬(shu)于(yu)連續(xu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi),其特點是輸(shu)出量隨輸(shu)入(ru)量的(de)變化(hua)而變化(hua),輸(shu)出量與輸(shu)入(ru)量之間存在一定的(de)比例(li)關系(xi)(xi)。比例(li)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)有(you)開(kai)環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)和(he)閉環控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)之分。 |
