Abstract
The utility model discloses a corrugated pipe compensator, which comprises a flange and a corrugated pipe, wherein the flange is connected with the corrugated pipe through a connecting pipe; the connecting pipe is connected with the end face of the flange in a sealed way. The corrugated pipe compensator is further characterized in that a groove is formed in the end face of the flange, wherein the connecting pipe is embedded into the groove; a spigot is arranged in a hole in the end, connected with the corrugated pipe, of the connecting pipe; the corrugated pipe is connected to the interior of the spigot in the sealed way; silica gel is filled in an axial gap between the end part of the connecting pipe and the corrugated pipe. According to the corrugated pipe compensator, the welding reliability is remarkably improved, a sealing effect is effectively ensured, and the service life is remarkably prolonged.
Description
Technical field
The utility model relates to the compensation device of pipeline, is specifically related to a kind of High-voltage Switchgear Industry GIS corrugated expansion joint 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, and in bellows and flange welding process, conventionally easily by bellows burn-through, and such welding part internal stress is larger, easily causes the seal failure of bellows in using process.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of soldering reliability that significantly improves, and effectively guarantees sealing effect, the corrugated expansion joint in significant prolongation working life.
The utility model is achieved through the following technical solutions technical goal.
Corrugated expansion joint, comprises flange, bellows; Its improvements are: between described flange and bellows, by adapter, be connected; Described adapter and end face of flange are tightly connected.
Further improve and be: described end face of flange is provided with groove, take over and be flush-mounted in this groove.
Further improve and be: in described adapter and bellows coupling end hole, be provided with seam, sylphon seal is connected in this seam.
Further improve and be: filling gel in axial clearance between described adapter end and bellows.
The utility model compared with prior art, has following good effect:
1, between flange and bellows, by adapter, be connected, significantly reduced the burn-through defect causing greatly because of wall thickness variation, significantly improve soldering reliability, effectively guarantee sealing effect, significant prolongation working life.
2, end face of flange arranges groove and is connected with taking over, and has improved the reliability that flange and adapter are connected.
3, take between end and bellows to filling gel in gap, further strengthened on the one hand the seal request of corrugated expansion joint, another aspect, also avoided in using process, take over and directly contact with bellows, play the effect of protecting bellows.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is II part enlarged diagram in Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Corrugated expansion joint shown in accompanying drawing, comprises flange 1, bellows 2; Between flange 1 and bellows 2, by taking over 3, be connected; Taking over 3 is connected with flange 1 end face seal; In the present embodiment, flange 1 end face is provided with groove, takes over 3 and is flush-mounted in this groove.
Take over 3 and be connected with bellows 2 in stomidium and be provided with seam, bellows 2 is sealedly attached in this seam; Take over the interior filling gel 4 of axial clearance between 3 ends and bellows 2.
