General-type end cover structure

Abstract

The invention discloses a general-type end cover structure. The structure comprises a metal end cover, a welding area is arranged on the top face of the metal end cover, and the outer surface of the welding area is of an arc structure; the height of the welding area is gradually decreased from the middle to the two sides, punched holes are formed in the middle and the outer edge of the welding area, and supporting flat bosses are punched on the portions, of the outer sides of the punched holes, of the outer edge; transition slopes are further distributed on the side edges of the supporting flat bosses and formed through punching, connection bases are welded to the upper ends of the punched holes, and the portions, located on the outer edge of the welding area, of the lower ends of the connection bases are placed in the corresponding supporting flat bosses. According to the general-type end cover structure, the problems are solved that an existing arc end cover forms an inclined angle after the connection bases are welded, the attractiveness of the whole structure is influenced, and the smoothness of air discharge or liquid discharge can also be influenced.

Description

technical field [0001] The invention relates to the technical field of end caps, in particular to a general-purpose end cap structure. Background technique [0002] The end cap refers to the structure that is welded or screwed on the end of some cylindrical structure containers for sealing, especially for gas storage tanks or oil storage tanks. Or liquid, the outer surface of the usual end cover is usually designed as a smooth arc structure with a high center and low edges, and then open a through hole on the end cover and weld the corresponding connection seat to connect the pipe used for exhaust or liquid discharge. If the connection seat is directly welded on the end cover, the welded connection seat will be inclined at a certain angle, which will not only affect the aesthetics of the overall structure, but also affect the smoothness of exhaust or liquid discharge. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a general-purpose end cover structure, which solves the problem that the current arc-shaped end cover will form an inclination angle after welding the connection seat, which not only affects the aesthetics of the overall structure, but also affects the exhaust Or the problem of drainage smoothness
