在φ1000mm的圆塔内,以空气.水为介质,对十字旋阀塔板的泄漏率进行了测试,考察了液流强度,出口堰高等因素对泄漏性能的影响,并将其与交错十字旋阀塔板、组合导向浮阀塔板和F1型浮阀塔板的泄漏率进行了对比.结果表明:十字旋阀塔板在气速超过临界网孔气速且液流强度较小时具有很好的漏液性能,经数据关联,获得了十字旋阀塔板漏液点孔速的关联式.
在φ1000mm的圓塔內,以空氣.水為介質,對十字鏇閥塔闆的洩漏率進行瞭測試,攷察瞭液流彊度,齣口堰高等因素對洩漏性能的影響,併將其與交錯十字鏇閥塔闆、組閤導嚮浮閥塔闆和F1型浮閥塔闆的洩漏率進行瞭對比.結果錶明:十字鏇閥塔闆在氣速超過臨界網孔氣速且液流彊度較小時具有很好的漏液性能,經數據關聯,穫得瞭十字鏇閥塔闆漏液點孔速的關聯式.

The weeping rates of cross-type valve trays were measured in a φ1000mm column by using air-water system,and the influence of liquid flow rate and outlet weir height were studied.The weeping rates of the cross-type valve trays in different situations were compared with the interlaced cross-type valve trays,the combined directed valve trays and the F1 valve trays,which shows that the cross-type valve trays have better weeping performance for small liquid stream and when the gas velocity is higher than the valve hole critical gas-velocity.By correlating the experimental data,equations of gas velocity with weeping point of the cross-type valve trays were obtained.
