Abstract
The invention discloses a kind of main drum flanges of high pressure GIS shells, including flange；Flange endoporus inner wall is equipped with groove；Further improvement lies in that：Flange end face upper surface is equipped with coaxial fitting, the identical external seal slot of groove width, interior sealing slot；The depth of external seal slot is less than the depth of interior sealing slot.The present invention is convenient for can guarantee structure size of the welding rear support on flange endoporus inner wall with the installation of rear support, and sealing reliability is high when use.
Description
Technical field
The present invention relates to high voltage substation field more particularly to a kind of main drum flanges of high pressure GIS shells.
Background technology
The main drum flange of high pressure GIS shells includes flange, in use, being welded to connect bearing on flange endoporus hole wall.It is existing
The main drum flange assembling of high pressure GIS shells, welding bearing are first to cross on flange endoporus hole wall, then press crossed centering bearing
Installation site after be welded to connect, this mode is time-consuming bothersome, and can not ensure weld rear support position.
Invention content
This is practical in view of the deficiencies of the prior art, and proposition is a kind of to be convenient for, with the installation of rear support, propping up after can guarantee welding
The main drum flange of high pressure GIS shells of structure size of the seat on flange endoporus inner wall.
The present invention is achieved through the following technical solutions technical goal.
The main drum flange of high pressure GIS shells, including flange；It is theed improvement is that：The flange endoporus inner wall is equipped with recessed
Slot.
In above structure, flange end face upper surface is equipped with coaxial fitting, the identical external seal slot of groove width, interior close
Sealing groove；The depth of the external seal slot is less than the depth of interior sealing slot.
Compared with prior art, the present invention having the positive effect that：
1. flange endoporus inner wall is equipped with groove, when later erection support, as long as in a groove by bearing installation, without scribing line
Centering, it is convenient and efficient, and can guarantee structure size of the welding rear support on flange endoporus inner wall.
2. end face of flange is equipped with coaxial fitting, the identical external seal slot of groove width, interior sealing slot, double sealing structure is aobvious
It writes and improves sealing reliability.
3. the depth of external seal slot is less than the depth of interior sealing slot, the present invention is in use, in outer seal groove, interior sealing slot
The sealing ring for installing same section, since the depth of external seal slot is less than the depth of interior sealing slot, in this way, being sealed in external seal slot
It is tighter than the sealing that sealing ring in interior sealing slot is formed to enclose the sealing formed, further increases sealing performance, reliability.

Specific implementation mode
The invention will be further described below according to attached drawing and in conjunction with the embodiments.
The main drum flange of the shell of high pressure GIS shown in attached drawing, including flange 1；1 endoporus inner wall of flange is equipped with groove 1.1；Flange
1 end face upper surface is equipped with coaxial fitting, the identical external seal slot of groove width, interior sealing slot；The depth of external seal slot is less than interior
The depth of seal groove.
Claims (2)
