Abstract
The utility model relates to a jacket flange, comprising a flange body and a flange jacket, wherein the circumference of the flange body is provided with an annular groove; the outer edges of the joint faces between the flange body and the flange jacket are respectively processed into chamfered structure; the two chamfered edges are combined into a V-type welding slope. The jacket flange has reasonable structure and improves the angle of the welding slope. The jacket flange has much left welding leg after being welded, processed and shaped, and the welding seams are full penetration welding seams, to avoid leakage in usage, improve safety and prolong the service life of the product.
Description
Technical field
The utility model relates to a kind of jacket flange, belongs to the chemical pipeline flange.
Background technique
For jacket flange, be welded by flange body and flange chuck, require flange body and the banjo clip cover to have good interchangeability.The flange chuck is the circulation of gas or liquid; it is not a standard piece; so have error when matching usually with flange body; this reprocesses after the two welds with regard to needs; yet the bevel for welding place between the two is often just at a finished edge angle at present; the another side structure is constant; and groove angle is generally 45 °; above-mentioned such structure it make the weldering meat at bevel for welding place less; after the good jacket flange of welding carries out a series of processing again; in use weld seam occurring through regular meeting has crackle, the problem that causes gas or liquid to be revealed.
Summary of the invention
The utility model is the problem that overcomes above-mentioned existence, and a kind of jacket flange is provided, and by changing the weld structure of body and chuck, with this angle that changes bevel for welding, makes aforementioned both welding more firm.
The utility model comprises flange body, flange chuck; The flange body circumference has circular groove, outer rim place, mating face between flange body and flange chuck is processed as chamfering structure respectively, and two bevel edges are combined to form " V " type bevel for welding, angle between two bevel edges, promptly groove angle α is preferably 70 °～80 °.
In the utility model, the distance between the summit of bevel for welding and the top of circular groove, promptly root face height H is in 1.0～2.0mm scope.
Banjo clip has put ozzle, and ozzle is the entry and exit of gas or liquid.
Weld at the place at bevel for welding, and what welding method adopted is the argon arc welding bottoming, the manual electric arc welding capping.
" V " type bevel for welding that the utility model forms, reasonable in design, and increased the angle of bevel for welding, this product is soldered good again after machine shaping, the remaining weldering meat of weld seam is many, and has guaranteed that weld seam is a complete penetraction and fusion in welding, and it in use leakage phenomenon can not occur, Safety performance is outstanding, has prolonged the working life of product.
