Abstract
The invention discloses a kind of double density sealing groove GIS corrugated expansion joint flanges, including flange;Several connecting holes are equipped on flange end face on the circumference centered on flange endoporus center, interior sealing slot is equipped on the inside of connecting hole;Flange is equipped with the end face indent of interior sealing slot, forms annular groove, and interior sealing slot is arranged in annular groove;Further improvement lies in that:Flange, which is equipped on the end face of interior sealing slot, is equipped with external seal slot on the outside of connecting hole, external seal slot is also disposed in annular groove;Interior sealing slot, external seal well width are identical, and the depth of external seal slot is less than the depth of interior sealing slot.Energy effective protection seal groove of the invention is not bruised, good seal performance.
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 joints include flange, bellows, take over, to play compensating action, in use, to sealing performance
There are strict requirements.It is equipped on the circumference centered on flange endoporus center on GIS corrugated expansion joint flange end faces
Several connecting holes are equipped with interior sealing slot on the inside of connecting hole, in use, installation sealing ring plays sealing function in seal groove.
The major defect of this GIS corrugated expansion joints flange is:Seal groove is in transport, installation process, seal groove of easily damaging,
Seal groove is once damaged, then can seriously affect the sealing performance of GIS corrugated expansion joints.
Invention content
This is practical in view of the deficiencies of the prior art, designs a kind of energy effective protection seal groove and is not bruised, so as to protect
Demonstrate,prove the double density sealing groove GIS corrugated expansion joint flanges of sealing performance.
The present invention is achieved through the following technical solutions technical goal.
Double density sealing groove GIS corrugated expansion joint flanges, including flange;On the flange end face in flange endoporus
Circumference centered on the heart is equipped with several connecting holes, and interior sealing slot is equipped on the inside of connecting hole;It is theed improvement is that:It is described
Flange is equipped with the end face indent of interior sealing slot, forms annular groove, and interior sealing slot is arranged in annular groove.
In above structure, the flange, which is equipped on the end face of interior sealing slot, is equipped with external seal slot, external seal on the outside of connecting hole
Slot is also disposed in annular groove.
In above structure, the interior sealing slot, external seal well width are identical, and the depth of the external seal slot is less than interior sealing
The depth of slot.
Compared with prior art, the present invention it has the positive effect that:
1. flange is equipped with the end face indent of interior sealing slot, annular groove is formed, interior sealing slot is arranged in annular groove, in this way, effective protection
Interior sealing slot is not bruised, so as to ensure the sealing performance of the present invention.
2. flange, which is equipped on the end face of interior sealing slot, is equipped with external seal slot on the outside of connecting hole, external seal slot is also disposed at ring
In slot, using double sealing structure, sealing performance and sealing reliability are significantly improved;External seal slot is also disposed in annular groove, is had
Effect protects external seal slot not to be bruised.
3. interior sealing slot, external seal well width are identical, the depth of external seal slot is less than the depth of interior sealing slot, in use,
The sealing ring of interior sealing slot, external seal slot installation same cross-sectional, the sealing structure that sealing ring is formed in external seal slot is closer, into
One step improves sealing performance and sealing reliability.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is left view in Fig. 1.
Fig. 3 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 GIS corrugated expansion joint flanges of double density sealing groove shown in attached drawing, including flange 1;With flange 1 on 1 end face of flange
Circumference centered on endoporus center is equipped with several connecting holes 1.1, this end face indent, forms annular groove 1.4, in annular groove 1.4
External seal slot 1.3, interior sealing slot 1.2 equipped with outer, interior fitting, in the present embodiment, interior sealing slot 1.2,1.3 width of external seal slot
Identical, the depth of external seal slot 1.3 is less than the depth of interior sealing slot 1.2.
