清管閥是一種主要用石油、天然氣、化工品及其它液體輸送管線中清管作業(yè)的新型裝置。進行清管器的發(fā)射、接收作業(yè),用于管道內(nèi)壁的機械清潔(除污 除銹、清除管道內(nèi)異物等)、分隔不同產(chǎn)品,已在油氣田、化工、碼頭、油氣儲運庫及海上平臺得到廣泛的應(yīng)用。
?產(chǎn)品特點
清管閥具有三種類型以適應(yīng)不同的作業(yè)需要。
?工作原理
本裝置密封原理與球閥相同,在彈簧與介質(zhì)共同作用下,使兩側(cè)閥座靠 緊球體,密封通道與閥體中腔隔開。通過旋轉(zhuǎn)球體來完成清管器的裝入、發(fā) 射和接收、取出。當球體通道對著快開盲板時可裝入、取出清管器(見圖一); 球體旋轉(zhuǎn)90度后,當球體通道與管道一致時在介質(zhì)作用下可發(fā)射、接收清管器(見圖二)。
