Description
Technical field
The utility model is related to a kind of flange, more precisely, being a kind of board-like 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 that transition is thinned with aeroelastic requirements and rational butt welding,
Weld bond is big from interface distance, and composition surface is deformed from welding temperature, and it takes more complicated loud-speaker physique structure, it is adaptable to
The pipeline of pipeline or high temperature, high pressure and low temperature that pressure or temperature fluctuate widely, is generally used for the pipeline that PN is more than 2.5MPa
And the connection of valve；It is also used for conveying on the pipeline of expensive, inflammable, explosive medium.The board-like butt welding generally used at present
Solder side between flange and body is generally plane, and this is unfavorable for body and flange after the welding of body and flange, welding fabrication
Between be also easily broken off.
Utility model content
The utility model is mainly the technical problem solved present in prior art, so as to provide a kind of plate of firm welding
Formula W.N flange.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of board-like W.N flange, comprising a ring flange, the center of ring flange be provided with an endoporus, ring flange be additionally provided with it is many
Individual screw, screw is centrosymmetric distribution centered on the center of circle of endoporus, and the side of ring flange is provided with an annular boss, convex annular
The internal diameter of platform is identical and interconnected with the internal diameter of endoporus, and a welding circle, welding circle and annular are provided with the top surface of annular boss
The internal diameter of boss is equal and interconnected, and the inner side of welding circle is provided with one first circular depressed, the central shaft of the first circular depressed
With the center overlapping of axles of welding circle, it is provided with the inner side of the first circular depressed in one second circular depressed, the second circular depressed
