Beschreibung
Zusammenfassung:The invention provides a sealing flange of a gas turbine cylinder and a design method thereof. The sealing flange comprises an upper flange connected with an upper half cylinder of a cylinder and a lower flange connected with a lower half cylinder of the cylinder, the upper flange and the lower flange are divided into an inner part and an outer part in the radial direction of the cylinder, an inner flange positioned in the inner part and an outer flange positioned in the outer part are made of different materials, and the thermal expansion coefficient of the material used for the inner flangeis greater than that of the material used for the outer flange; and the outer flange is provided with bolt holes for assembling bolts. The inner flange and the outer flange are made of different materials, and the expansion amount of the inner flange is larger than that of the outer flange, so that the opening gap at the inner side of a split flange in a gas turbine is reduced, and the sealing performance of the split fla
