Abstract

The utility model relates to a flange high in strength and not prone to deformation. The flange high in strength and not prone to deformation comprises a flange body (1). The flange body (1) comprises a flange end portion (1.1) and a flange neck portion (1.2). The inclination of the flange end portion (1.1) is 37.5 degrees. The flange neck portion (1.2) is a circular truncated cone with the taper of 24.5 degrees. A first through hole (2) is formed in the flange body (1). Second through holes (3) annularly arranged are evenly formed in the flange body (1). According to the flange high in strength and not prone to deformation, the flange neck portion is arranged, so that the flange is not prone to deformation when used for a long time in connection of pipelines with pressure or temperature fluctuating to a large extent or pipelines with high temperature or high pressure or low temperature; the second through holes are evenly formed in the flange body, so that the weight of the flange is reduced to a large extent, force received by a whole flange plate is even, the phenomena of eccentricity and the like are avoided, and the mechanical strength of the flange is guaranteed.

Description

High, the on-deformable flange of a kind of intensity
Technical field
The utility model relates to a kind of flange, belongs to the mechanical fastener technical field.
Background technique
Flange is as a kind of mechanical fastener, high speed development along with automated machine equipment, requirement to the volume of machinery and weight is more and more higher, when especially the weight of machinery is excessive, the freight of machinery also will increase greatly, and simultaneously general end face of flange is plane, during the pipeline fluctuated widely in pressure or temperature or the pipeline of high temperature, high pressure and low temperature connect, the connection part of pipe fitting and flange easily is out of shape, and affects using effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of lightweight, intensity is high, on-deformable flange.
The purpose of this utility model is achieved in that
High, the on-deformable flange of a kind of intensity, be characterized in: described flange comprises flange body, flange body comprises flange end and flange neck, described flange end is with the gradient of 37.5 °, the flange neck is 24.5 ° of round platforms of a tapering, be provided with the first through hole on flange body, evenly be provided with the second through hole of circular array on described flange body, described the second through hole has four at least.
High, the on-deformable flange of a kind of intensity of the utility model, its flange body adopts alloy steel material to make.
High, the on-deformable flange of a kind of intensity of the utility model, its first through hole and the second through hole are circular hole.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is due to the flange neck, during the pipeline therefore fluctuated widely in pressure or temperature or the pipeline of high temperature, high pressure and low temperature connect, long-time use not yielding.;
2, the second through hole of the present utility model is arranged on flange body uniformly, can significantly reduce the weight of flange, and makes whole flange plate stressed evenly, not there will be the phenomenons such as eccentric, has guaranteed the mechanical strength of flange.
The accompanying drawing explanation
Fig. 1 is that a kind of intensity of the utility model is high, the structural representation of on-deformable flange.
The A that Fig. 2 is Fig. 1 is to sectional drawing.
In figure:
Flange body 1,
Flange end 1.1,
Flange neck 1.2,
The first through hole 2,
The second through hole 3.
Embodiment
Referring to Fig. 1-2, the utility model relates to high, the on-deformable flange of a kind of intensity, it comprises flange body 1, flange body 1 comprises flange end 1.1 and flange neck 1.2, and described flange end 1.1 is with the gradient of 37.5 °, and flange neck 1.2 is 24.5 ° of round platforms of a tapering, be provided with the first through hole 2 on flange body 1, evenly be provided with the second through hole 3 of circular array on described flange body 1, described the second through hole 3 has four at least, and described flange body 1 adopts alloy steel material to make.
Working principle: the utility model is due to flange neck 1.2, therefore during the pipeline fluctuated widely in pressure or temperature or the pipeline of high temperature, high pressure and low temperature connect, long-time use is not yielding, and the second through hole 3 is arranged on flange body 1 uniformly, can significantly reduce the weight of flange, and make whole flange plate stressed evenly, not there will be the phenomenons such as eccentric, guaranteed the mechanical strength of flange.
