摘要：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阀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。
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.
