Abstract
The invention discloses a kind of destressing GIS corrugated expansion joint flanges, including flange；Flange end face is equipped with interior sealing slot, and the other end is equipped with inner stopper；It is theed improvement is that：Flange is equipped on the end face of inner stopper is equipped with annular groove II on the outside of inner stopper, and annular groove II is arc groove；Further improvement lies in that：Flange is equipped with the end face indent of interior sealing slot, forms annular groove I, and interior sealing slot is arranged in annular groove I.The present invention can discharge flange inner stopper outer end face in the welding process and take between welding stress, flange is avoided to generate eave tile phenomenon, effective protection interior sealing slot is not bruised, so as to ensure the sealing performance of the present invention.
Description
Technical field
The present invention relates to the compensation devices of pipeline, and in particular to the GIS bellow-type expansions used in a kind of High-voltage Switchgear Industry
Device flange.
Background technology
GIS corrugated expansion joint flanges, including flange；Flange end face is equipped with interior sealing slot, and the other end is equipped with interior stop
Mouthful.The major defect of this GIS corrugated expansion joints flange is：In use, flange inner stopper outer end face and take over outer wall it
Between weld seam generate larger convergent force so that flange generates eave tile phenomenon.
Invention content
This is practical in view of the deficiencies of the prior art, designs a kind of destressing for being avoided that flange and generating eave tile phenomenon
GIS corrugated expansion joint flanges.
The present invention is achieved through the following technical solutions technical goal.
Destressing GIS corrugated expansion joint flanges, including flange；The flange end face is equipped with interior sealing slot, another
End is equipped with inner stopper；It is theed improvement is that：The flange is equipped on the end face of inner stopper is equipped with annular groove II on the outside of inner stopper,
Annular groove II is arc groove.
In above structure, the flange is equipped with the end face indent of interior sealing slot, forms annular groove I, and interior sealing slot is arranged on ring
In slot I.
Compared with prior art, the present invention it has the positive effect that：
1. flange is equipped on the end face of inner stopper is equipped with annular groove II on the outside of inner stopper, annular groove II is arc groove, can welded
Welding stress between flange inner stopper outer end face is discharged in journey and is taken over, avoids flange from generating eave tile phenomenon.
2. flange is equipped with the end face indent of interior sealing slot, annular groove I is formed, interior sealing slot is arranged in annular groove I, in this way, having
Effect protects interior sealing slot not to be bruised, so as to ensure the sealing performance of the present invention.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is I enlarged schematic partial view in Fig. 1.
Specific embodiment
The invention will be further described below according to attached drawing and in conjunction with the embodiments.
The corrugated expansion joint flange of destressing GIS shown in attached drawing, including flange 1；1 end face of flange is equipped with interior sealing slot
1.2, the other end is equipped with inner stopper 1.5；Flange 1 is equipped on the end face of inner stopper 1.5 is equipped with annular groove II in 1.5 outside of inner stopper
1.6, annular groove II 1.6 is arc groove.
Flange 1 is equipped with the end face indent of interior sealing slot 1.2, forms annular groove I 1.4, and interior sealing slot 1.2 is arranged on annular groove I 1.4
It is interior.
Claims (2)
