Abstract
The utility model discloses a kind of octagon flange, comprise flange body, one is had for the pipe arrangement hole of connecting tube in the middle of flange body, flange body offer for the fixing mounting hole of bolt, it is characterized in that: described flange body is arranged to octagon, and offer lightening core in described flange body.Lightening core is opened in the inner side of intersecting line angle outside octagon flange, is circular oval or square or regular hexagon etc.; Octagon flange eight crossing line angles are set as circular arc type.The utility model provides a kind of novel octagon flange, and structure is simple, and join strength is good, plays stronger fixation, be convenient to attended operation simultaneously, there is the weight alleviating flange casting, reduce the effect of cost of production, easy to use, be suitable for practicality, there is the value in industry.
Description
Technical field
The utility model relates to the flange field in a kind of component of machine field, particularly relates to the flange coupling connector that a kind of pipeline connects.
Background technique
Flange is again flange plate or bead, makes pipe and the interconnective part of pipe, is connected to pipe end.Perforation on flange, can wear bolt, and bolt makes two flanges be close to, and uses liner containment between flange.Flange connect is made up of a pair flange, a pad and several bolt and nuts.Pad is placed between two flange facings, and after fastening nut, the specific pressure on gasket surface produces distortion after reaching certain numerical value, and fills up uneven place on sealing surface, and connection is not tightly leaked.
Flange joint is the important Placement of pipeline construction.Flange joint is easy to use, can bear larger pressure.In industrial pipeline, the use of Flange joint is very extensive.Existing a lot of pipe fitting and equipment all carry flange plate, belong to flanged fitting.It can be formed by casting, also can form by being threaded or welding.
But the flange in prior art exists crystallized ability difference, foundry goods overall weight weight, the deficiency that cost of production is high, so need to improve its structure.
Model utility content
Main purpose of the present utility model is, overcomes deficiency of the prior art, provides a kind of octagon flange of new structure.It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and join strength is good, alleviates the weight of flange casting simultaneously, reduces the flange of cost of production, and have the value in industry.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of octagon flange, comprise flange body, one is had for the pipe arrangement hole of connecting tube in the middle of flange body, flange body offer for the fixing mounting hole of bolt, it is characterized in that: described flange body is arranged to octagon, and offer lightening core in described flange body.
Adopt technique scheme, the octagon of flange body arranges structure simply, and join strength is good, plays stronger fixation, is also convenient to attended operation simultaneously, the easy skidding occurred when there will not be circular flange to install.In flange body, offer lightening core serves the weight alleviating flange casting simultaneously, reduces the effect of cost of production.
The utility model is set to further: described mounting hole is 4; Octagon flange eight crossing line angles are set as circular arc type.By adopting technique scheme, the connection of pipeline can be realized; And circular arc type corner is conducive to the effects such as the comfort level operated.
The utility model is further set to: described lightening core is for circular oval or square, or the regular polygon such as regular hexagon; It is opened in the inner side that octagon flange intersects line angle, and quantity is 8.In addition, lightening core also can be opened in other vacant positions of flange body except mounting hole.By adopting technique scheme, not only alleviating the weight of flange casting, reducing cost of production, and increasing mounting hole at needs temporarily, when not being very high to the requirement of mounting hole again, playing the effect of reinforcement by connection.
In sum, the technological scheme of a kind of novel octagon flange of the utility model, overcome the deficiencies in the prior art, have structure simple, join strength is good, alleviate the weight of flange casting simultaneously, reduce the advantages such as cost of production, and easy to use, be suitable for practicality, be worthy to be popularized, there is the value in industry.
Foregoing is only the general introduction of technical solutions of the utility model, and in order to clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of octagon flange of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of octagon flange, comprise flange body 1, one is had for the pipe arrangement hole 2 of connecting tube in the middle of flange body 1, flange body offer for the fixing mounting hole 3 of bolt, it is characterized in that: described flange body 1 is arranged to octagon, and offers lightening core 5 in described flange body.Described mounting hole 3 is 4.Described lightening core 5 is circular oval or square, or the regular polygon such as regular hexagon; Lightening core 5 can be opened in the inner side of 4 crossing line angles outside octagon flange, and quantity is 8.In addition, octagon flange eight crossing line angles are set as circular arc type.
Innovative point of the present utility model is, the octagon of flange arranges and plays effect that is fixing and convenient operation installation, and the weight alleviating flange casting is played in the setting of lightening core, reduces the advantages such as cost of production.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
