摘　　要：通过对Ｎｏｒｔｏｎ公司的专利浮阀塔板与我国通用的Ｆ－１型浮阀塔板的理论分析，推导出双阀重浮阀塔板干板压降的理论模型，对于解决浮阀塔板在低汽速时，较筛板略大的液面落差而导致塔板上气体的不均匀分布和严重的塔板入口泄漏问题，具有极为重要的意义。Based on theoretical analysis of both the float valve tray with Norton Company patent and the F 1 type float valve tray generally used in China,the theoretical model is established for dry plate pressure drop of the double valve weighed float valve tray.It is important to solve the non homogeous distribution problem of gas on tray and serious leak problem at the tray inlet caused by slightly greater liquid level drop of float valve tray than it of sieve tray when the vapor rate of the float valve tray is low.
