Abstract

The utility model discloses a hubbed flange. When two flange disks are in butt joint with each other, due to the fact that concave and convex butting joint portions and a gasket are provided, the two flange disks are both not prone to generating dislocation, overall sealing performance is strong, and meanwhile, due to the fact that the flange disks and flange round tubes are in butt joint with each other in a spot welding mode, the rigidity is better. The hubbed flange comprises hubbed flange bodies formed by the disks and the round tubes, the hubbed flange bodies are two in number, the first hubbed flange body is formed by a first disk and a first round tube, and the second hubbed flange body is formed by a second disk and a second round tube. The first disk and the first round tube are in butt joint after spot welding is carried out, and the second disk and the second round tube are in butt joint after spot welding is carried out. Hemispherical protrusions are formed in the first disk, and hemispherical grooves are formed in the second disk correspondingly. Mounting holes are formed in the first disk and the second disk, and studs penetrate through the mounting holes and connect the first disk and the second disk. The gasket is further arranged between the first disk and the second disk.

Description

A kind of hubbed flange
Technical field
The utility model relates to pipeline installation fitting field, is specifically related to flange.
Background technique
Flange can be divided into polytype according to different applicable situations; The general rigidity of common hubbed flange is larger, and it has pipe and disk, and hubbed flange is generally used for the occasion that pressure and temp is higher; When two disks of tradition hubbed flange dock, disc face is plane, and therefore easily dislocation, cause poor sealing; Meanwhile, the integral rigidity of traditional hubbed flange also needs to strengthen.
The model utility content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of hubbed flange is provided, two flange disks are when docking, it has concavo-convex docking part, pad and two flange disks all are difficult for producing dislocation, and overall tightness is strong, meanwhile, the flange disk is that spot welding is docked with the flange pipe, and its rigidity is better.
The utility model solves the technological scheme that its technical problem adopts: a kind of hubbed flange, comprise the hubbed flange body formed by disk and pipe, described hubbed flange body is two, be respectively the first hubbed flange body formed by the first disk and the first pipe, the second hubbed flange body formed by the second disk and the second pipe;
Above-mentioned the first disk and the docking of the first pipe point postwelding, above-mentioned the second disk and the docking of the second pipe point postwelding;
Be manufactured with hemispherical projections on above-mentioned the first disk, the making hemispherical groove of correspondence on above-mentioned the second disk;
Offer mounting hole on above-mentioned the first disk and the second disk, stud bolt is connected the first disk by mounting hole with the second disk;
Also be provided with pad between above-mentioned the first disk and the second disk.
Further: the mounting hole on above-mentioned the first disk and the second disk is respectively eight, and the hemispherical projections on described the first disk is four, corresponding, the hemispherical groove on described the second disk is also four.
The utility model compared with prior art has the following advantages:
The utility model hubbed flange, owing on its flange disk, being respectively arranged with projection and groove, therefore two flange disks are when docking, it has concavo-convex docking part, pad and two flange disks all are difficult for producing dislocation, and overall tightness is strong, meanwhile, the flange disk is that spot welding is docked with the flange pipe, and its rigidity is better.

Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
Fig. 1 and Fig. 2 show a kind of concrete structure of the present utility model, as shown in the figure, a kind of hubbed flange, comprise the hubbed flange body formed by disk and pipe, described hubbed flange body is two, be respectively the first hubbed flange body formed by the first disk 2 and the first pipe 1, the second hubbed flange body formed by the second disk 4 and the second pipe 5;
1 postwelding docking of above-mentioned the first disk 2 and the first pipe, 5 postwelding docking of above-mentioned the second disk 4 and the second pipe;
Be manufactured with hemispherical projections 6 on above-mentioned the first disk 2, the making hemispherical groove 8 of correspondence on above-mentioned the second disk 4;
Offer mounting hole on above-mentioned the first disk 2 and the second disk 4, stud bolt 3 is connected the first disk 2 by mounting hole with the second disk 4;
Also be provided with pad 7 between above-mentioned the first disk 2 and the second disk 4.
Preferably, the mounting hole on above-mentioned the first disk 2 and the second disk 4 is respectively eight, and the hemispherical projections 6 on described the first disk 2 is four, corresponding, the hemispherical groove 8 on described the second disk 4 is also four.
The above is explained in detail the utility model preferred implementation by reference to the accompanying drawings, but the utility model is not limited to above-mentioned mode of execution, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
