ATOS比例(li)閥特點(dian): - 可實(shi)現(xian)壓力、速度的(de)無極調(diao)節(jie),避免了常通的(de)開關式氣閥換(huan)向時的(de)沖(chong)擊(ji)現(xian)象。
- 能實(shi)現遠程(cheng)控制和程(cheng)序控制。
- 與斷續控(kong)制相比,系統簡(jian)化,元件大(da)大(da)減(jian)少(shao)。
- 與液(ye)壓比(bi)(bi)例閥相(xiang)比(bi)(bi),體積小、重(zhong)量輕(qing)、結構簡單(dan)、成本較(jiao)低,但響應速度比(bi)(bi)液(ye)壓系統慢得多,對負載(zai)變化也比(bi)(bi)較(jiao)敏感(gan)。
- 使用功率小、發熱少、噪聲低(di)。
- 不會(hui)發生火災,*。受溫度變(bian)化的影響小。

ATOS阿托斯比例(li)閥(fa)向(xiang)閥(fa)屬于比例(li)閥(fa)的(de)一種,用(yong)來(lai)控制流(liu)量和流(liu)向(xiang)。 電(dian)氣(qi)比(bi)例(li)(li)閥(fa)(fa)(fa)自動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)可分成(cheng)斷(duan)續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)和連(lian)續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)。斷(duan)續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi)即開關控(kong)(kong)(kong)(kong)制(zhi)(zhi)。氣(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)統(tong)(tong)中使(shi)用動(dong)作頻(pin)率較低的(de)開關式(shi)(ON-OFF)的(de)換向(xiang)閥(fa)(fa)(fa)來控(kong)(kong)(kong)(kong)制(zhi)(zhi)氣(qi)路(lu)的(de)通斷(duan)。靠減(jian)壓(ya)閥(fa)(fa)(fa)來調(diao)節(jie)(jie)所(suo)需要(yao)的(de)壓(ya)力,靠節(jie)(jie)流閥(fa)(fa)(fa)來調(diao)節(jie)(jie)所(suo)需要(yao)的(de)流量(liang)。這種傳統(tong)(tong)的(de)氣(qi)動(dong)控(kong)(kong)(kong)(kong)制(zhi)(zhi)系(xi)統(tong)(tong)要(yao)想要(yao)有(you)多(duo)個(ge)(ge)輸出(chu)力和多(duo)個(ge)(ge)運(yun)動(dong)速度,就需要(yao)多(duo)個(ge)(ge)減(jian)壓(ya)閥(fa)(fa)(fa)、節(jie)(jie)流閥(fa)(fa)(fa)及換向(xiang)閥(fa)(fa)(fa)。這樣,不僅(jin)元件(jian)需要(yao)多(duo),成(cheng)本高,構成(cheng)系(xi)統(tong)(tong)復雜,且許多(duo)元件(jian)都需要(yao)預(yu)先進行人工調(diao)節(jie)(jie)。電(dian)氣(qi)比(bi)例(li)(li)閥(fa)(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)屬于連(lian)續(xu)控(kong)(kong)(kong)(kong)制(zhi)(zhi),其特(te)點(dian)是輸出(chu)量(liang)隨輸入(ru)量(liang)的(de)變化而變化,輸出(chu)量(liang)與(yu)輸入(ru)量(liang)之間存在一定的(de)比(bi)例(li)(li)關系(xi)。比(bi)例(li)(li)控(kong)(kong)(kong)(kong)制(zhi)(zhi)有(you)開環控(kong)(kong)(kong)(kong)制(zhi)(zhi)和閉(bi)環控(kong)(kong)(kong)(kong)制(zhi)(zhi)之分。 |
