Abstract
The invention discloses a corrugated expansion joint, which comprises flanges and a corrugated pipe; each flange is connected with the corrugated pipe through a connecting pipe; each connecting pipe is hermetically connected with the end face of the corresponding flange. The further improvement is that a groove is formed in the end face of each flange; each connecting pipe is embedded into the corresponding groove; a rabbet is formed in the connecting end hole of each connecting pipe and the corrugated pipe; the corrugated pipe is hermetically connected with the interiors of the rabbets; silica gel fills an axial gap between the end part of each connecting pipe and the corrugated pipe. According to the corrugated expansion joint disclosed by the invention, the welding reliability is obviously improved, the sealing effect is effectively ensured, and the service life is obviously prolonged.
Description
Technical field
The present invention relates to the compensation device of pipeline, be specifically related to the GIS corrugated expansion joint that a kind of High-voltage Switchgear Industry is used.
Background technique
High-voltage Switchgear Industry GIS corrugated expansion joint used comprises flange, bellows, and general bellows is directly connected by welded seal with flange endoporus hole wall.Because bellows is very thin, and flange is very thick, and both thickness difference are very large, usually easy by bellows burn-through in bellows and flange welding process, and such welding part internal stress is comparatively large, easily causes the seal failure of bellows in using process.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and significantly improve soldering reliability, effectively ensure sealing effect, the corrugated expansion joint in significant prolongation working life.
The present invention is achieved through the following technical solutions technical goal.
Corrugated expansion joint, comprises flange, bellows; Its improvements are: described flange is connected by taking over between bellows; Described adapter and end face of flange are tightly connected.
Further improvement is: described end face of flange is provided with groove, and adapter is flush-mounted in this groove.
Further improvement is: be provided with seam in described adapter and bellows coupling end hole, sylphon seal is connected in this seam.
Further improvement is: filling gel in axial clearance between described pipe ends and bellows.
The present invention compared with prior art, has following good effect:
1, be connected by adapter between flange with bellows, significantly reduce the burn-through defect because wall thickness variation causes greatly, significantly improve soldering reliability, effectively ensure sealing effect, significant prolongation working life.
2, end face of flange arranges groove and is connected with adapter, improves flange and the reliability that is connected of adapter.
3, between pipe ends and bellows to filling gel in gap, further enhance on the one hand the seal request of corrugated expansion joint, another in, it also avoid in using process, adapter directly contacts with bellows, plays the effect protecting bellows.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is II enlarged schematic partial view in Fig. 1.
Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
Corrugated expansion joint shown in accompanying drawing, comprises flange 1, bellows 2; Be connected by adapter 3 between flange 1 with bellows 2; Adapter 3 is connected with flange 1 end face seal; In the present embodiment, flange 1 end face is provided with groove, and adapter 3 is flush-mounted in this groove.
Adapter 3 is connected in stomidium with bellows 2 and is provided with seam, and bellows 2 is sealedly attached in this seam; Filling gel 4 in axial clearance between adapter 3 end and bellows 2.
