ATOS防爆閥DHA-0631/2/M/7WP 24DC/BT低溫是把設備可能點燃爆炸性氣體混合物的部件全部封閉在一個外殼內,其外殼能夠承受通過外殼任何接合面或結構間隙,滲透到外殼內部的可燃性混合物在內部爆炸而不損壞,并且不會引起外部由一種、多種氣體或蒸氣形成的爆炸性環境的點燃,把可能產生火花、電弧和危險溫度的零部件均放入隔爆外殼內,隔爆外殼使設備內部空間與周圍的環境隔開。隔爆外殼存在間隙,因電氣設備呼吸作用和氣體滲透作用,使內部可能存在爆炸性氣體混合物。

ATOS防爆閥DHA型結構說明: ①閥體(ti) ②線軸 ③防爆螺線管 ④手動優(you)先 ⑤電纜密封套的螺紋連(lian)接 ⑥內部端子板,用于(yu)電纜連接
工作原(yuan)理(li):電(dian)磁閥(fa)里有(you)密(mi)閉(bi)的腔,在(zai)不(bu)同(tong)(tong)位置開有(you)通(tong)(tong)孔,每個孔都通(tong)(tong)向不(bu)同(tong)(tong)的油(you)(you)管(guan),腔中間是閥(fa),兩面是兩塊電(dian)磁鐵,哪面的磁鐵線圈通(tong)(tong)電(dian)閥(fa)體就會被吸引到哪邊,通(tong)(tong)過控制(zhi)(zhi)閥(fa)體的移動(dong)(dong)來檔住或漏出不(bu)同(tong)(tong)的排油(you)(you)的孔,而進(jin)油(you)(you)孔是常(chang)開的,液壓油(you)(you)就會進(jin)入不(bu)同(tong)(tong)的排油(you)(you)管(guan),然后(hou)通(tong)(tong)過油(you)(you)的壓力來推動(dong)(dong)油(you)(you)缸的活(huo)(huo)塞(sai)(sai)(sai),活(huo)(huo)塞(sai)(sai)(sai)又帶動(dong)(dong)活(huo)(huo)塞(sai)(sai)(sai)桿(gan),活(huo)(huo)塞(sai)(sai)(sai)竿帶動(dong)(dong)機械裝置動(dong)(dong)。這樣通(tong)(tong)過控制(zhi)(zhi)電(dian)磁鐵的電(dian)流就控制(zhi)(zhi)了(le)機械運(yun)動(dong)(dong)。
