Abstract
A kind of divided edge structure of spherical tank spherical shell board, it is characterized in that comprising top crown (3) and bottom crown (6), the volume of the large groove weld (8) of top crown (3) inner side is greater than the volume of the little groove weld (7) in top crown (3) outside, and the volume of the large groove weld (8) of bottom crown (6) inner side is less than the volume of the little groove weld (7) in bottom crown (6) outside.Of the present utility model by after above-mentioned divided edge structure improvement: 1) gouge, polishing work concentrate on downhand position and carries out, labour intensity significantly reduces, quality has had guarantee, 2) most of weld seam carries out back chipping, polishing outside spherical tank, improve the operating environment in tank, 3) upper pole, upper girth joint non-machined groove welding job be converted to flush joint position by overhead position, reduce the welding difficulty of welder, flush joint welding current is relatively large simultaneously, is conducive to melting out of defect.
Description
Technical field
The utility model relates to chemical technology field, especially a kind of divided edge structure of spherical tank spherical shell board, for the divided edge structure of large-size spherical tank (oil, chemical industry, metallurgy, town gas etc.) manual arc welding method.
Background technology
Current thick spherical storage tank groove of spherical shell plate design generally adopts asymmetry X-groove, and large groove is outside spherical tank, this kind of groove type must first weld weld seam outside spherical tank when spherical tank assembly welding, rear welding spherical tank weld joint on inner side, as Fig. 1, top crown (3) and bottom crown (6) is respectively equipped with between spherical tank outer wall (1) and spherical tank inwall (2), the inner side of top crown (3) and bottom crown (6) is little groove weld (4) inside top crown, the outside of top crown (3) and bottom crown (6) is large groove weld (5) outside top crown, this structure Problems existing is as follows:
(1) on spherical tank, the overhead position such as pole and upper girth joint is on the low side relative to other position solder yield;
(2) carrying out carbon arc air gouging back chipping generation volume of smoke in tank accumulates in spherical tank, causes Working in confined space bad environments in tank, has a strong impact on Health Status For Workers Exposed.
(3) overhead weld position soldering seam grinding, polishing labour intensity high, at substantial manpower and materials, cause production efficiency low.
Summary of the invention
The purpose of this utility model is the divided edge structure providing a kind of spherical tank spherical shell board.The utility model, by changing the divided edge structure of spherical tank top crown, upper temperature zone plate and equator zone plate, reaches the object improving welding quality, reduce labour intensity, improve operating environment.
The technical solution of the utility model is:
A kind of divided edge structure of spherical tank spherical shell board, comprise top crown and bottom crown, the volume of the large groove weld inside top crown is greater than the volume of the little groove weld outside top crown, and the volume of the large groove weld inside bottom crown is less than the volume of the little groove weld outside bottom crown; Outside described top crown, little groove weld is connected with groove weld large inside top crown is the overall weld seam of a hourglass shape; Outside described top crown, inside little groove weld and top crown, the shape of large groove weld is fan-shaped.
The utility model by the groove type of top crown, upper temperature zone plate and equator zone plate by large groove little groove outside spherical tank change to inside spherical tank large groove inside spherical tank little groove outside spherical tank.
The beneficial effects of the utility model are:
Of the present utility model by after above-mentioned divided edge structure improvement:
1 gouge, polishing work concentrate on downhand position to carry out, and labour intensity significantly reduces, and quality has had guarantee,
2 most of weld seams carry out back chipping, polishing outside spherical tank, improve the operating environment in tank,
On 3, the welding job of pole, upper girth joint non-machined groove is converted to flush joint position by overhead position, reduces the welding difficulty of welder, and flush joint welding current is relatively large simultaneously, is conducive to melting out of defect.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure: 1, spherical tank outer wall, 2, spherical tank inwall, 3, top crown, 4, little groove weld inside top crown, 5, large groove weld outside top crown, 6, bottom crown, 7, little groove weld outside top crown, 8, large groove weld inside top crown.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As Fig. 2, a kind of divided edge structure of spherical tank spherical shell board, comprise top crown 3 and bottom crown 6, the volume of the large groove weld 8 inside top crown 3 is greater than the volume of the little groove weld 7 outside top crown 3, and the volume of the large groove weld inside bottom crown 6 is less than the volume of the little groove weld outside bottom crown 6; Outside described top crown, little groove weld 7 is connected with groove weld 8 large inside top crown is the overall weld seam of a hourglass shape; Outside described top crown, inside little groove weld 7 and top crown, the shape of large groove weld 8 is fan-shaped.
Adopt the divided edge structure of spherical tank spherical shell board of the present utility model to carry out the work of spherical tank assembly welding, namely improve working environment, improve welding quality and again reduce overall construction cost simultaneously.
Embodiment recited above is only be described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement; all should fall into protection domain of the present utility model, the technology contents of the utility model request protection is all recorded in detail in the claims.
