摘　　要：1 INTRODUCTIONValve tray columns are one of the most important mass transfer equipment for vapor-liquidoperations and are widely used in the petroleum and chemical industries.They have good op-erating performances with floatable parts on the trays.There are various of valve trays,andType V1(F1-type)valve trays are used very common in industry.Though Type V1 valvetrays have a number of advantages,it has been found in recent years that there are also cer-tain drawbacks,for example,higher hydraulic gradient on the tray,more backmixing
