昆山阿斯麗自動(dòng)化設(shè)備有限公司，ATOS比例閥RZGA-A-033/80/M/7 31意大利阿托斯銷售 意大利ATOS比例閥原理特點(diǎn)
ATOS伺服比例閥 基本工作原理：atos比例閥通過電子參考信號(hào)調(diào)節(jié)液壓或動(dòng)力參數(shù)。比例閥的基本原理：相應(yīng)的參考信號(hào)產(chǎn)生對(duì)應(yīng)的電磁鐵吸力，電磁鐵吸力作用在靠彈簧復(fù)位的閥芯上，驅(qū)動(dòng)閥芯運(yùn)動(dòng)，從而實(shí)現(xiàn)要求的液壓參數(shù)調(diào)節(jié)。
Atos數(shù)字式伺服比例閥可靠性高，可與的伺服閥媲美 ... 是比例技術(shù)的體現(xiàn)，阿托斯伺服閥閥芯-閥套精密遮蓋，可閉環(huán)反饋，安全復(fù)位，高響應(yīng)，數(shù)字式電子放大器出廠預(yù)設(shè)，流量/壓力/位置數(shù)字控制，功能參數(shù)可通過軟件設(shè)置，對(duì)振動(dòng)和沖擊有耐震選項(xiàng)，防爆&不銹鋼特殊型式可選。
ATOS比例閥結(jié)構(gòu)原理
輸入信號(hào)增大，供氣用ATOS電磁比例閥先導(dǎo)閥1換向，而排氣用電磁先導(dǎo)閥7處于復(fù)位狀態(tài)，則供氣壓力從SUP口通過閥1進(jìn)入先導(dǎo)室5，先導(dǎo)室壓力上升，氣壓力作用在膜片2的上方，則和膜片2相連的供氣閥芯4便開啟，排氣閥芯3關(guān)閉，產(chǎn)生輸出壓力。此輸出壓力通過壓力傳感器6反饋至控制回路8。在這里，與目標(biāo)值進(jìn)行快速比較修正，知道輸出壓力與輸入信號(hào)成一定比例為止，從而得到輸出壓力與輸入信號(hào)的變化成比例的變化。由于沒有噴嘴擋板機(jī)構(gòu)，故閥對(duì)雜質(zhì)不敏感，可靠性高。
ATOS比例閥特點(diǎn)
1)可實(shí)現(xiàn)壓力、速度的無極調(diào)節(jié)，避免了常通的開關(guān)式氣閥換向時(shí)的沖擊現(xiàn)象。
2)能實(shí)現(xiàn)遠(yuǎn)程控制和程序控制。
3)與斷續(xù)控制相比，系統(tǒng)簡化，元件大大減少。
4)與液壓比例閥相比，體積小、重量輕、結(jié)構(gòu)簡單、成本較低，但響應(yīng)速度比液壓系統(tǒng)慢得多，對(duì)負(fù)載變化也比較敏感。
5)使用功率小、發(fā)熱少、噪聲低。
