For achieving the above object; The technical scheme that the present invention adopts is: a kind of skirt structure; The basic ring flat-plate that comprises cylindrical shell, is fixed on first pipe nipple of cylinder top and is installed in the cylindrical shell bottom; The top of said cylindrical shell is fixed with first short tube, and the middle part of said cylindrical shell is provided with back plate and is installed in second short tube on the back plate, is provided with connecting panel between said first pipe nipple.
In preferred embodiment of the present invention, the skirt structure further comprises and is provided with the insulation bracing ring that is positioned at connecting panel below between the said cylindrical shell.
In preferred embodiment of the present invention, the skirt structure comprises that further said cylindrical shell top is provided with floor, intermediate plate, first gusset, first backing plate successively, and grips through double-screw bolt, nut.
In preferred embodiment of the present invention, the skirt structure further comprises between said intermediate plate and said first gusset and also is provided with pad, base plate.
In preferred embodiment of the present invention, the skirt structure comprises that further said cylindrical shell bottom is arranged with manhole and second pipe nipple that is located at the manhole upper and lower end face.
In preferred embodiment of the present invention, the skirt structure comprises that further the quantity of said second short tube is three.
In preferred embodiment of the present invention, the skirt structure comprises that further the adjacent said second short tube equal angles evenly is located on the periphery of said back plate.
In preferred embodiment of the present invention, the skirt structure comprises that further extending to the outer basic ring flat-plate two ends of said cylindrical shell is fixed with on second gusset, said second gusset and is fixed with cover plate, is fixed with second backing plate on the said cover plate.
In preferred embodiment of the present invention, the skirt structure comprises that further said basic ring flat-plate is vertical with the line of centers of said cylindrical shell.
The invention solves the defective that exists in the background technology, compact conformation of the present invention, firm welding, safety performance satisfies standard-required, and few, the simple installation of consumptive material has shortened the duration, has reduced productive costs, has good economic benefits and social benefit.
