Description
Technical field
The present invention relates to a kind of flange, more precisely, being a kind of band neck W.N flange.
Background technology
W.N flange is one kind of pipe fitting, refers to flange that is with neck and having pipe transition and being connected with pipe butt welding.
W.N flange is unlikely to deform, good seal, is widely used, and has corresponding rigidity and aeroelastic requirements and the thinning transition of rational butt welding,
Weld bond is big from interface distance, and composition surface deforms from welding temperature, and it takes more complicated loud-speaker physique structure, it is adaptable to
Pipeline or the pipeline of high temperature, high pressure and low temperature that pressure or temperature fluctuate widely, are generally used for pipelines of the PN more than 2.5MPa
And the connection of valve；On the pipeline for being also used for convey expensive, inflammable, explosive medium.The band neck butt welding for commonly using at present
The neck shape boss of flange more puts down narrow with the solder side of body, and the connection after welding fabrication between body and flange is not enough consolidated,
It is susceptible to the situation of fracture.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so as to provide a kind of band for welding and more consolidating
Neck W.N flange.
Above-mentioned technical problem of the invention is mainly what is be addressed by following technical proposals：
A kind of band neck W.N flange, comprising a ring flange, the center of ring flange is provided with an endoporus, is additionally provided with ring flange many
Individual screw, screw is centrosymmetric distribution centered on the center of circle of endoporus, and the side of ring flange is provided with a truncated cone boss, convex
The inside of platform is provided with through hole, and the diameter of the through hole is identical with the diameter of endoporus and is interconnected, on the top anchor ring of boss
A ring-shaped depression is provided with, the center of circle of ring-shaped depression is located on the central shaft of endoporus, the ring section of ring-shaped depression is square.
Used as preferred embodiments of the present invention, the described depth of ring-shaped depression and the height ratio of boss is 1：7.
Used as preferred embodiments of the present invention, the described height of boss and the thickness ratio of ring flange is 3：1.
It is of the invention to be provided with a truncated cone boss, the boss shape in the endoporus side of ring flange with neck W.N flange
Sat into a neck-shaped welding, a ring-shaped depression is provided with the top anchor ring of the boss, body and boss after so welding
Between formed solid face of weld, so as to substantially increase steadiness.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation with neck W.N flange of the invention.
Specific embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in figure 1, a kind of band neck W.N flange 1, comprising a ring flange 10, the center of ring flange 10 is provided with one
Hole 11, is additionally provided with multiple screws 12 on ring flange 10, screw 12 is centrosymmetric distribution, flange centered on the center of circle of endoporus 11
The side of disk 10 is provided with a truncated cone boss 20, and the inside of boss 20 is provided with through hole, diameter and the endoporus 11 of the through hole
Diameter it is identical and be interconnected, a ring-shaped depression 30 is provided with the top anchor ring of boss 20, the center of circle of ring-shaped depression 30 is located at
On the central shaft of endoporus 11, the ring section of ring-shaped depression 30 is square.
Used as to further improvement of the present invention, the described depth of ring-shaped depression 30 and the height ratio of boss 20 is 1：
7。
Used as to further improvement of the present invention, the described height of boss 20 and the thickness ratio of ring flange 10 is 3：1.
The invention with neck W.N flange is provided with a truncated cone boss, the boss shape in the endoporus side of ring flange
Sat into a neck-shaped welding, a ring-shaped depression is provided with the top anchor ring of the boss, body and boss after so welding
Between formed solid face of weld, so as to substantially increase steadiness.
Below mentality of designing of the invention is only illustrated in one embodiment, and in the case where system is allowed, the present invention can
To expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
