Description
Technical field
The utility model belongs to machine components systems technology field, and in particular to a kind of welded seal flange.
Background technology
In well known technical field, flanged joint is made of a pair of of flange, a gasket and several bolt and nuts, gasket
It is placed between two flange sealing surfaces, after tightening nut, the ratio pressure on gasket surface is deformed after reaching certain numerical value, and is filled up
Uneven place on sealing surface makes connection not leak tightly to achieve the purpose that sealing, but the mode of this mechanical seal is easy
Loosening is generated, the effect of sealing is influenced, therefore it provides a kind of sealing effect is good and welded seal flange easy to use is very
It is necessary to.
Invention content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide that a kind of sealing effect is good and user
Just welded seal flange.
What the purpose of this utility model was realized in：A kind of welded seal flange, it includes ring flange, the flange
The centre of disk is provided with through-hole, and the bore periphery is provided with bolt hole, and the bolt hole periphery is provided with annular groove,
The annular groove setting is provided with gasket in ring flange outermost, the ring flange.
The beneficial effects of the utility model：The utility model is provided with gasket, makes in the part of two ring flanges contact
With sealing shroud, it is that two ring flanges are in close contact, the peripheral part of ring flange is provided with annular groove, connecting two flanges
When disk, welding is carried out in the part of annular groove, keeps the sealing effect of flanged joint more preferable, using more convenient.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of welded seal flange of the utility model.
