Description
Technical field
The utility model is related to a kind of flange, more precisely, being a kind of hubbed clip-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.The ring flange of the slip-on welding flange generally used at present is more by single metal or conjunction
Gold is made, and metal rigidity is had a surplus elastic deficiency.Some bodys are when in use easily by larger impulsive force, when these
Impulsive force directly acts on flange and body, then easily causes the breakage of body and flange, and the normal of influence body is used.
Utility model content
The utility model is mainly the technical problem solved present in prior art, so that providing one kind itself has preferably
The hubbed clip-on-welding flange of elasticity.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of hubbed clip-on-welding flange, comprising a ring flange, the center of ring flange is provided with endoporus, the endoporus in ring flange side
Provided with a welding boss, be provided with an endoporus in welding boss, endoporus is connected with the endoporus of ring flange center, ring flange with
An elastic ring is provided between welding boss, two top surfaces of elastic ring are mutually be bonded with ring flange and welding boss respectively, in ring flange
On be additionally provided with multiple screws, screw is centrosymmetric distribution centered on the center of circle of ring flange, and ring flange is made up of composite board,
Composite board is sandwich construction, and composite board is from top to bottom followed successively by vinyon layer, rubber layer and layer of PVC, polyethylene modeling
The bed of material, rubber layer and layer of PVC are mutually bonded.
As the utility model preferred embodiment, described rubber layer is nitrile rubber layer.
As the utility model preferred embodiment, the thickness ratio of described vinyon layer, rubber layer and layer of PVC is
5：3：3.
The ring flange of hubbed clip-on-welding flange of the present utility model is made of composite board, and the composite is three-decker,
It is most middle for elastic rubber layer, while being also provided with an elastic ring, the hubbed clip-on-welding flange between ring flange and welding boss
The rubber layer and elastic ring of upper setting can absorb larger impulsive force in use, have in itself to flange and body slow
Protective effect is rushed, the safety in utilization of flange and body is improved.
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.
