Abstract
The utility model discloses an integral type box flange structure, both ends are provided with the open-ended box about including, box both ends opening part is provided with the lateral wall of bending of the certain angle of inwards bending of lateral wall, the lateral wall tip of bending is provided with the flange that outwards bends and be on a parallel with the horizontal plane, the box is bent and is provided with the transition limit between lateral wall and the flange, the flange surface is provided with equidistant distribution's pilot hole, the edge of flange does not surpass the edge of box. Integral type box flange structure is integrated into one piece, flange and box need not the welding, have simple structure, the leakproofness is good, because of adopting the flange edge not to surpass the design at box edge again, can avoid the risk of coming and going staff collision flange.
Description
Technical Field
The utility model relates to a box flange technical field, concretely relates to integral type box flange structure.
Background
In dust removal purification equipment, the main tank body is connected with an external component through a flange, the existing flange structure is formed by directly welding the flange to the tank body, as shown in figure 1, the structure is not only troublesome to process, but also cannot be accurately centered due to the fact that the flange deforms more or less during welding, or connection failure is caused due to poor welding quality. Meanwhile, the outer edge of the flange protrudes out of the edge of the box body, and the passing workers easily collide with the flange, so that potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide a simple structure, need not the welding, the good integral type box flange structure of leakproofness.
In order to achieve the purpose, the technical scheme of the utility model a design an integral type box flange structure, both ends are provided with the open-ended box about including, box both ends opening part is provided with the lateral wall of bending of the certain angle of inwards bending of lateral wall, the lateral wall tip of bending is provided with the flange that outwards bends and be on a parallel with the horizontal plane, the box is bent the lateral wall and is provided with the transition limit with flange joint department, the flange surface is provided with equidistant distribution's pilot hole, the edge of flange does not surpass the edge of box.
Further preferably, the inward bending angle of the bent side wall of the box body is 10-80 degrees.
In order to enhance the sealing performance when the flange is connected with the corresponding connecting piece, a ring of first annular grooves are further preferably arranged on the inner ring of the flange.
In order to further enhance the sealing performance when the flange is connected with other connecting pieces, a further preferable technical scheme is that a ring of second annular grooves are arranged on the outer ring of the flange.
In a further preferred embodiment, a first sealing washer and a second sealing washer are respectively disposed in the first annular groove and the second annular groove, and the first sealing washer and the second sealing washer are made of rubber.
In a further preferred scheme, the material of the box body flange is carbon steel.
When the box body flange is connected with other connecting piece flanges, the connecting piece flange structure is arranged to be a mirror image of the box body flange structure, a first sealing washer and a second sealing washer which are corresponding in size are arranged in a first annular groove and a second annular groove of the box body flange, the assembling hole of the connecting piece flange corresponds to the assembling hole position of the box body flange, the assembling hole is locked by using a bolt and a nut, and when the box body flange and the connecting piece flange are in a compression state, the thickness of the sealing ring is reduced by extrusion, so that the box body flange and the connecting piece flange can be better sealed.
The utility model has the advantages and the beneficial effects that: the integrated box body flange structure is integrally formed, the flange and the box body do not need to be welded, the structure is simple, the sealing performance is good, and the assembly problem caused by flange deformation caused by welding can be solved; meanwhile, the flange edge does not exceed the design of the box body edge, and potential safety hazards can not be caused to the workers who come and go.
Drawings
FIG. 1 is a front view of a welded structure of a tank and a flange in the prior art;
FIG. 2 is a schematic structural view of the integrated box flange structure of the present invention;
fig. 3 is a schematic cross-sectional view of the flange enlarging structure of the present invention.
In the figure: 1. a box body; 2. bending side wall
(ii) a 3. A flange; 4. an assembly hole; 5. a transition edge; 6. a first annular groove; 7. a second annular groove.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 2-3, the utility model relates to an integral type box flange structure, both ends are provided with open-ended box 1 about including, box both ends opening part is provided with the lateral wall 2 of bending of the certain angle of inwards bending of lateral wall, the lateral wall tip of bending is provided with the flange 3 that outwards bends and be on a parallel with the horizontal plane, the box is bent the lateral wall and is provided with transition limit 5 with flange joint department, the flange surface is provided with equidistant distribution's pilot hole 4, the edge of flange 3 does not surpass the edge of box 1.
Further preferably, the inward bending angle of the bent side wall is 10-80 degrees.
In order to enhance the sealing performance when the flange is connected with the corresponding connecting piece, a ring of first annular grooves 6 are further preferably arranged on the inner ring of the flange.
In order to further enhance the sealing performance when the flange is connected with other connecting pieces, a ring of second annular groove 7 is further preferably arranged on the outer ring of the flange.
In a further preferred embodiment, a first sealing washer and a second sealing washer are respectively disposed in the first annular groove and the second annular groove, and the first sealing washer and the second sealing washer are made of rubber.
In a further preferred scheme, the material of the box body flange is carbon steel.
When the box body flange structure is connected with the connecting piece flange, the connecting piece flange structure is arranged to be a mirror image of the flange structure, a first sealing washer and a second sealing washer with corresponding sizes are arranged in the first annular groove 6 and the second annular groove 7 of the flange, the assembling hole of the connecting piece flange corresponds to the position of the assembling hole of the flange, the assembling hole is locked by bolts and nuts, and when the flange and the connecting piece flange are in a compression state, the thickness of the sealing washer is reduced by extrusion, so that the flange and the connecting piece flange can be better sealed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
