意大利ATOS比例閥特點： - 可實現(xian)壓力、速度的無極調節，避免了常通的開關式氣閥(fa)換向時(shi)的沖擊現(xian)象。
- 能實現遠程(cheng)控(kong)制和(he)程(cheng)序(xu)控(kong)制。
- 與斷續控制相比，系統簡化，元件大大減少。
- 與液壓(ya)比(bi)例閥相比(bi)，體(ti)積(ji)小、重量輕、結(jie)構簡單(dan)、成本較低(di)，但響(xiang)應(ying)速度比(bi)液壓(ya)系統(tong)慢得多(duo)，對負載變化也比(bi)較敏感。
- 使用功率小(xiao)、發熱少、噪聲低(di)。
- 不會發生火災，*。受溫度變化的影響小。

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。 電氣比(bi)例閥自動控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)可分(fen)成斷續(xu)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)和(he)連(lian)(lian)續(xu)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)。斷續(xu)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)即開(kai)關控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)。氣動控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)系(xi)統(tong)(tong)中使用(yong)動作頻率較低的開(kai)關式(ON-OFF)的換(huan)向閥來(lai)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)氣路的通斷。靠減壓(ya)閥來(lai)調節所(suo)需(xu)要的壓(ya)力，靠節流(liu)閥來(lai)調節所(suo)需(xu)要的流(liu)量(liang)。這(zhe)種傳統(tong)(tong)的氣動控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)系(xi)統(tong)(tong)要想(xiang)要有多(duo)(duo)(duo)(duo)個(ge)輸(shu)出(chu)力和(he)多(duo)(duo)(duo)(duo)個(ge)運(yun)動速度，就需(xu)要多(duo)(duo)(duo)(duo)個(ge)減壓(ya)閥、節流(liu)閥及換(huan)向閥。這(zhe)樣，不僅(jin)元(yuan)件(jian)需(xu)要多(duo)(duo)(duo)(duo)，成本高，構成系(xi)統(tong)(tong)復雜，且(qie)許多(duo)(duo)(duo)(duo)元(yuan)件(jian)都需(xu)要預先進(jin)行人(ren)工調節。電氣比(bi)例閥控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)屬于(yu)連(lian)(lian)續(xu)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)，其特點是輸(shu)出(chu)量(liang)隨輸(shu)入量(liang)的變化而(er)變化，輸(shu)出(chu)量(liang)與輸(shu)入量(liang)之間存在(zai)一定(ding)的比(bi)例關系(xi)。比(bi)例控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)有開(kai)環(huan)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)和(he)閉環(huan)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)之分(fen)。 |
