Abstract
The invention discloses a novel plate-type flat welding flange. The novel plate-type flat welding flange comprises a flange plate. A flange inner hole is formed in the center of the flange plate. Multiple screw holes are formed in the flange plate. The screw holes are distributed with the center of circle of the flange inner hole as the center in a central symmetry manner. An annular boss is arranged on one side of the flange inner hole. The annular boss is equal to the flange inner hole in inner diameter. An inclined face is arranged on the outer side of the annular boss. An inclination angle of 35-45 degrees is formed between the inclined face and the plane where the flange plate is located. A seal welding ring is arranged on the top face of the annular boss. The seal welding ring is equal to the annular boss in inner diameter. Multiple welding grooves are formed in the top face of the seal welding ring. According to the novel plate-type flat welding flange, the seal welding ring is arranged on the annular boss, after flat welding of a pipe body and the flange plate is conducted, the seal welding ring can be welded, and therefore a fully sealed structure is formed between the pipe body and the flange plate; and external gas and fluid cannot enter the fully sealed structure, and the corrosion resistance of the novel plate-type flat welding flange is improved greatly.
Description
Technical field

Background technology
Slip-on welding flange is commonly abbreviated as flat board, also claims slip-on flange.Slip-on welding flange is first to insert pipe with the connection of pipeline
Enter flange endoporus to appropriate location, then joint welding again.Slip-on welding flange is applied to pressure rating than relatively low, pressure oscillation, vibration and
In the not serious tubing of concussion.Slip-on welding flange advantage is easier to centering, and price when being slip-on welding flange assemble welding
It is relatively cheap, thus be widely used.But, the slip-on welding flange generally existing welding for commonly using at present is not enough caused
It is close, corrosion-prone shortcoming.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so as to provide a kind of New-type plate downhand welding method
It is blue.
What the above-mentioned technical problem of the present invention was mainly addressed by following technical proposals:
A kind of New-type plate slip-on welding flange, comprising a ring flange, the center of ring flange is provided with a flange endoporus, on ring flange
It is additionally provided with multiple screws, screw is centrosymmetric centered on the center of circle of flange endoporus distribution, and the side of flange endoporus is provided with one
Annular boss, the internal diameter of annular boss are equal with the internal diameter of flange endoporus, and an inclined-plane, inclined-plane and method are provided with the outside of annular boss
The face that blue disk is located is in 35-45 degree inclination angle, is provided with a sealing welding ring in the top surface of annular boss, the internal diameter of sealing welding ring with
The internal diameter of annular boss is equal, and the top surface of sealing welding ring is provided with some welding grooves.
It is 1 as the thickness ratio of preferred embodiments of the present invention, described annular boss and ring flange:5.
Used as preferred embodiments of the present invention, described sealing welding ring is made up of aluminium alloy.
The New-type plate slip-on welding flange of the present invention is provided with a sealing welding ring on annular boss, in body and flange
Sealing welding ring can be carried out welding after disk downhand welding, be formed between such body and ring flange and fully seal structure, extraneous gas
Liquid cannot be introduced into, so as to substantially increase its corrosion resistance.
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
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

The top surface of shape boss 20 is provided with a sealing welding ring 30, and the internal diameter of sealing welding ring 30 is equal with the internal diameter of annular boss 20, close
The top surface of envelope welding ring 30 is provided with some welding grooves 31.
It is 1 as the thickness ratio to further improvement of the present invention, described annular boss 20 and ring flange 10:5.
Used as to further improvement of the present invention, described sealing welding ring 30 is made up of aluminium alloy.
The New-type plate slip-on welding flange of the invention is provided with a sealing welding ring on annular boss, in body and flange
Sealing welding ring can be carried out welding after disk downhand welding, be formed between such body and ring flange and fully seal structure, extraneous gas
Liquid cannot be introduced into, so as to substantially increase its corrosion resistance.
Below only in one embodiment come illustrate the present invention mentality of designing, system allow in the case of, the present invention can
To expand to while external more functional modules, so as to extend its function to greatest extent.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
