Description
Technical field
The present invention relates 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 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 board-like butt welding for commonly using at present
Solder side between flange and body mostly is plane, and this is unfavorable for the welding of body and flange, body and flange after welding fabrication
Between be also easily broken off.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so as to provide a kind of the board-like right of firm welding
Welding method is blue.
What the above-mentioned technical problem of the present invention was mainly addressed by following technical proposals：
A kind of board-like W.N flange, comprising a ring flange, the center of ring flange is provided with an endoporus, multiple spiral shells is additionally provided with ring flange
Hole, screw are centrosymmetric centered on the center of circle of endoporus distribution, and the side of ring flange is provided with an annular boss, annular boss
Internal diameter is identical with the internal diameter of endoporus and is interconnected, and is provided with a welding circle, welding circle and annular boss in the top surface of annular boss
Internal diameter it is equal and be interconnected, be provided with one first circular depressed on the inside of welding circle, the central shaft of the first circular depressed with it is molten
The center overlapping of axles of adapter ring, is provided with one second circular depressed, the central shaft of the second circular depressed on the inside of the first circular depressed
Coincide with the central shaft of the first circular depressed.
Used as preferred embodiments of the present invention, the thickness ratio of described ring flange, annular boss and welding circle is 7：2：5.
It is 3 as the depth ratio of preferred embodiments of the present invention, the first described circular depressed and the second circular depressed：2.
The board-like W.N flange of the present invention is provided with an annular boss in the endoporus side of ring flange, and the top surface of boss sets
Put a welding circle, the inner side of the welding circle arranges two-stage circular depressed, such body and flange after the completion of welding each other
Between can form a three-dimensional solder side, so as to substantially increase the fastness of body and flange.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
