Abstract
The utility model discloses a kind of band neck W.N flange, include a welding cylinder, weld and an endoporus is provided with cylinder, the one end and a ring flange for welding cylinder are welded, ring flange is made up of sheet metal, the edge of ring flange is bent to welding cylinder direction, an annular groove is formed between ring flange and welding cylinder, multiple screws are provided with groove, screw is centrosymmetric distribution centered on the center of circle of endoporus, it is additionally provided with a pair of positioning holes in groove, positioning hole is centrosymmetric distribution centered on the center of circle of endoporus, positioning hole is used for being rotatably connected for ring flange and joint outer part.Ring flange of the present utility model with neck W.N flange is made of sheet metal piece, the ring flange with certain mechanical strength is formed after sheet metal edge bending, this structure has smaller weight in the case where ensureing the normal linkage function of ring flange, so that the overall weight with neck W.N flange is substantially reduced, the waste of material is thus substantially reduced in the case where ensureing flange function.
Description
Technical field
The utility model is related 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 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.It is general using wider W.N flange
Formed by metal material casting, ring flange and welding neck are thicker, and overall weight is higher, and for the less tubing of some pressure such as
Fruit is then more wasted using such flange.
Utility model content
The utility model is mainly the technical problem solved present in prior art, so as to provide a kind of overall more light
Band neck 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 band neck W.N flange, comprising a welding cylinder, an endoporus is provided with welding cylinder, one end and the flange of cylinder is welded
Disk is welded, and ring flange is made up of sheet metal, and the edge of ring flange is bent to welding cylinder direction, the shape between ring flange and welding cylinder
Into an annular groove, multiple screws are provided with groove, screw is centrosymmetric distribution centered on the center of circle of endoporus, recessed
It is additionally provided with a pair of positioning holes in groove, positioning hole is centrosymmetric distribution centered on the center of circle of endoporus, positioning hole is used for ring flange
With being rotatably connected for joint outer part.
As the utility model preferred embodiment, described welding cylinder is made up of aluminium alloy.
As the utility model preferred embodiment, the described thickness of ring flange and the thickness ratio of welding cylinder is 1：8.
Ring flange of the present utility model with neck W.N flange is made of sheet metal piece, shape after sheet metal edge bending
Into the ring flange with certain mechanical strength, this structure has smaller in the case where ensureing the normal linkage function of ring flange
Weight it is thus big in the case where ensureing flange function so that the overall weight with neck W.N flange is substantially reduced
The big waste for reducing material.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram of the present utility model with neck W.N flange；
Fig. 2 be Fig. 1 in ring flange structural representation.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As shown in Figure 1 and Figure 2, a kind of band neck W.N flange 1, comprising a welding cylinder 30, an endoporus is provided with welding cylinder 30
11, one end of welding cylinder 30 is welded with a ring flange 10, and ring flange 10 is made up of sheet metal, and the edge of ring flange 10 is to welding
The bending of 30 directions of cylinder, forms an annular groove 13 between ring flange 10 and welding cylinder 30, multiple screws is provided with groove 13
12, screw 12 is centrosymmetric distribution centered on the center of circle of endoporus 11, and a pair of positioning holes 20 are additionally provided with groove 13, is positioned
Hole 20 is centrosymmetric distribution centered on the center of circle of endoporus 11, and positioning hole 20 is used for the rotation of ring flange 10 and joint outer part
Connection.
Further improved as to the utility model, described welding cylinder 30 is made up of aluminium alloy.
Further improved as to the utility model, the thickness ratio of the thickness and welding cylinder 30 of described ring flange 10
For 1：8.
The ring flange with neck W.N flange of the utility model is made of sheet metal piece, shape after sheet metal edge bending
Into the ring flange with certain mechanical strength, this structure has smaller in the case where ensureing the normal linkage function of ring flange
Weight it is thus big in the case where ensureing flange function so that the overall weight with neck W.N flange is substantially reduced
The big waste for reducing material.
Only illustrate mentality of designing of the present utility model in one embodiment above, in the case where system allows,
The utility model can expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
