The utility model discloses a kind of new slip-on welding flange, include a ring flange, the center of ring flange is provided with an endoporus, multiple screws are additionally provided with ring flange, screw is centrosymmetric distribution centered on the center of circle of endoporus, in the side of ring flange provided with a welding boss, the internal diameter for welding boss is equal with the internal diameter of endoporus, weld the central shaft of boss and the center overlapping of axles of endoporus, multiple positioning holes are provided with the another side of ring flange, the depth of positioning hole is less than the thickness of ring flange, an inserting column is respectively provided with each positioning hole, positioning hole is centrosymmetric distribution centered on the center of circle of endoporus.New slip-on welding flange of the present utility model is provided with multiple positioning holes in ring flange for external side, an inserting column is also respectively arranged in each positioning hole, when the positioning hole and inserting column when two panels flange docks fixed on ring flange are engaged fixation each other, so even if along central shaft reciprocating motion relative displacement will not also occur for flange, improve the sealing between flange.
Description
Technical field
The utility model is related to a kind of flange, more precisely, being a kind of new slip-on welding flange.
Background technology
Slip-on welding flange is commonly abbreviated as flat board, also claims slip-on flange.The connection of slip-on welding flange and pipeline is first to insert pipe
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
Shake in not serious pipe-line system.Slip-on welding flange advantage is to be easier to centering, and price during slip-on welding flange assemble welding
It is relatively cheap, thus be widely used.Generally connected between the ring flange of slip-on welding flange by screw rod, but be due to screw rod
There is gap between screw, when flange needs along central shaft reciprocating rotation in use, between ring flange easily
Relatively move, so that the sealing between influenceing flange.
Utility model content
The utility model is mainly the technical problem solved present in prior art, so as to provide a kind of be engaged to each other tightly
Close new slip-on welding flange.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of new slip-on welding flange, comprising a ring flange, the center of ring flange, which is provided with an endoporus, ring flange, also to be set
There are multiple screws, screw is centrosymmetric distribution centered on the center of circle of endoporus, in the side of ring flange provided with a welding boss,
The internal diameter for welding boss is equal with the internal diameter of endoporus, the central shaft of boss and the center overlapping of axles of endoporus is welded, in ring flange
Another side is provided with multiple positioning holes, and the depth of positioning hole, which is less than in the thickness of ring flange, each positioning hole, is respectively provided with an inserting column,
Positioning hole and inserting column when two panels flange, which is docked, to be fixed on ring flange are engaged fixation each other, and positioning hole is with the circle of endoporus
Be centrosymmetric distribution centered on the heart.
As the utility model preferred embodiment, the depth of described positioning hole is less than the 1/2 of flange thickness.
As the utility model preferred embodiment, the cross section of described positioning hole is ellipse.
New slip-on welding flange of the present utility model is provided with multiple positioning holes, Mei Geding in ring flange for external side
Position is also respectively arranged an inserting column in hole, when the positioning hole and inserting column when two panels flange docks fixed on ring flange
Occlusion is fixed each other, and relative displacement also will not occur even if being moved back and forth along central shaft for such flange, improve close between flange
Feng Xing.
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 additionally provided with multiple screws 12 on one endoporus 11, ring flange 10, screw 12 is centrosymmetric distribution centered on the center of circle of endoporus 11,
In the side of ring flange 10 provided with a welding boss 20, the internal diameter for welding boss 20 is equal with the internal diameter of endoporus 11, welds boss
20 central shaft and the center overlapping of axles of endoporus 11, multiple positioning holes 30 are provided with the another side of ring flange 10, positioning hole 30
Depth, which is less than in the thickness of ring flange 10, each positioning hole 30, is respectively provided with an inserting column 31, when two panels flange docks fixation
Wait positioning hole 30 and inserting column 31 on ring flange and be engaged fixation each other, positioning hole 30 is in center centered on the center of circle of endoporus 11
It is symmetrical.
Further improved as to the utility model, the depth of described positioning hole 30 is less than the thickness of ring flange 10
1/2。
Further improved as to the utility model, the cross section of described positioning hole 30 is ellipse.
The new slip-on welding flange of the utility model is provided with multiple positioning holes, Mei Geding in ring flange for external side
Position is also respectively arranged an inserting column in hole, when the positioning hole and inserting column when two panels flange docks fixed on ring flange
Occlusion is fixed each other, and relative displacement also will not occur even if being moved back and forth along central shaft for such flange, improve close between flange
Feng Xing.
Only illustrate mentality of designing of the present utility model in one embodiment above, in the case where system allows,
