Abstract
The invention discloses a welding neck flange. The welding neck flange comprises a disc-shaped flange body. A butt welding part is arranged on one end face of the flange body and comprises a first hollow frustum part welded and fixed to one end face of the flange body, and a second hollow frustum part arranged on the outer end face of the first hollow frustum part. A through hole is formed among the flange body, the first hollow frustum part and the second hollow frustum part. The included angle between the outer side face of the first hollow frustum part and the horizontal plane ranges from 42 degrees to 48 degrees. The included angle between the outer side face of the second hollow frustum part and the horizontal plane ranges from 72 degrees to 78 degrees. A welding inserting groove is formed in the outer end face of the second hollow frustum part. By means of the above manner, the welding neck flange is simple and reasonable in structure and high in strength, and the welding effect of the welding neck flange and a pipeline is good.
Description
Technical field
The present invention relates to flange technical field, more particularly to a kind of W.N flange.
Background technology
Flange is a kind of fastening means, and flange connection refers to be connected with each other as one group by flange, pad and bolt three
The releasable connection of combined sealing structure.Flange divides threaded（Screwed connection）Flange, welded flange and clip flange.Flange is even
Connect because its connection sealing is good, stabilized structure, intensity are high, easy to use, low cost and other advantages, be widely used in building row
Industry, urban water supply, boilers and pressure vessel, petroleum industry, supply, chemical industry, grocery trade, fire-fighting, pharmaceutical industry, power station, water
The industries such as profit, HVAC.W.N flange is the one kind in flange, and existing W.N flange could be improved.
Content of the invention
The present invention solves the technical problem of providing a kind of W.N flange, simple and reasonable, intensity height, with pipeline
Welding effect is good.
For solving above-mentioned technical problem, one aspect of the present invention is：A kind of W.N flange is provided, including：
Flange body in the form of annular discs, is provided with butt welding portion on the end face of the flange body, the butt welding portion includes and flange sheet
The first hollow prismoid section that body end face is welded and fixed and the second hollow frustum being arranged on the first hollow prismoid section outer face
Portion, forms a through hole between the flange body, the first hollow prismoid section and the second hollow prismoid section, and described first is hollow
Angle between the lateral surface of prismoid section and horizontal plane is 42 ~ 48 degree, the lateral surface of the second hollow prismoid section and horizontal plane
Between angle be 72 ~ 78 degree, on the outer face of the second open circles frustum have one welding slot.
Angle in a preferred embodiment of the present invention, between the lateral surface of the first hollow prismoid section and horizontal plane
For 45 degree.
Angle in a preferred embodiment of the present invention, between the lateral surface of the second hollow prismoid section and horizontal plane
For 75 degree.
The invention has the beneficial effects as follows：W.N flange of the present invention, simple and reasonable, intensity height, with pipeline welding effect
Good.
Description of the drawings
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, below will be to making needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing, wherein：
Fig. 1 is the structural representation of one preferred embodiment of W.N flange of the present invention.
In accompanying drawing, the labelling of each part is as follows：1st, flange body, the 2, first hollow prismoid section, the 3, second hollow prismoid section,
4th, through hole, 5, welding slot.
Specific embodiment
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 is referred to, the embodiment of the present invention includes：
A kind of W.N flange, including：Flange body 1 in the form of annular discs, is provided with butt welding portion on the end face of the flange body,
The butt welding portion is included the first hollow prismoid section 2 being welded and fixed with flange body end face and is arranged on the first hollow prismoid section
The second hollow prismoid section 3 on outer face, forms between the flange body, the first hollow prismoid section and the second hollow prismoid section
One through hole 4, the angle between the lateral surface of the first hollow prismoid section and horizontal plane is 42 ~ 48 degree, and described second is empty
Angle between the lateral surface of heart prismoid section and horizontal plane is 72 ~ 78 degree, and said structure causes flange to have higher intensity.
There is on the outer face of the second open circles frustum a welding slot 5, be easy to pipeline insertion welding, weld matter
Amount is high.
Preferably, the angle between the lateral surface of the described first hollow prismoid section and horizontal plane is 45 degree.
Preferably, the angle between the lateral surface of the described second hollow prismoid section and horizontal plane is 75 degree.
The invention has the beneficial effects as follows：W.N flange of the present invention, simple and reasonable, intensity height, with pipeline welding effect
Good.
Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
