Abstract
A kind of metallic hose comprises bellows (5), adapter (2) is respectively equipped with at bellows two ends, the one end taken over away from bellows is welded with flange (1), it is characterized in that having weld-ring (3) weld-ring to be welded to connect on bellows in the end sleeve of bellows, the external diameter of weld-ring is equal with the external diameter of bellows crest, one metal net cover (6) is enclosed within bellows and weld-ring, on metal net cover, cover has one section of sheathed casing (4), the external diameter of described adapter is less than the external diameter of weld-ring, sheathed casing, one end of metal net cover and weld-ring and the other end of adapter are welded to connect, the cross section of its weld seam is right-angled triangle.This metallic hose is provided with metal net cover and dispersibles the stress that bellows bears on bellows, metal net cover is provided with sheathed casing the connection part of bellows and weld-ring can be avoided impaired, drastically increase the working life of metallic hose.
Description
Technical field
The utility model relates to a kind of metallic hose, and it comprises bellows, is respectively equipped with adapter and flange, for flexibly connecting between pressure piping at bellows two ends.
Background technique
Metallic hose generally includes bellows and is arranged on adapter and the flange at bellows two ends, flange is connected with pressure piping, bellows has axial displacement and the angular displacement that flexibility can compensate pipeline, at some application requirements bellowss, there is enough length, this makes bellows intermediate portion bear larger stress, easily makes bellows be out of shape impaired; The connection part of bellows and adapter is easily damaged in addition, therefore needs to make improvements.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of metallic hose, and it dispersibles the stress of bellows intermediate portion, ensures that bellows works reliably.
This metal hose package draws together bellows 5, adapter 2 is respectively equipped with at bellows two ends, the one end taken over away from bellows is welded with flange 1, it is characterized in that having weld-ring 3 weld-ring to be welded to connect on bellows in the end sleeve of bellows, the external diameter of weld-ring is equal with the external diameter of bellows crest, one metal net cover 6 is enclosed within bellows and weld-ring, on metal net cover, cover has one section of sheathed casing 4, the external diameter of described adapter is less than the external diameter of weld-ring, one end of sheathed casing, metal net cover and weld-ring and the other end of adapter are welded to connect, and the cross section of its weld seam is right-angled triangle.
The length of described sheathed casing is that peak separation sum is saved in the thickness of weld-ring and 2 to 4 of bellows.
This metallic hose is provided with metal net cover and dispersibles the stress that bellows bears on bellows, metal net cover is provided with sheathed casing the connection part of bellows and weld-ring can be avoided impaired, drastically increase the working life of metallic hose.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in accompanying drawing represents respectively: 1-flange, 2-adapter, 3-weld-ring, 4-sheathed casing, 5-bellows, 6-metal net cover.
Embodiment
Existing accompanying drawings embodiment of the present utility model.
This metal hose package draws together bellows 5, adapter 2 is respectively equipped with at bellows two ends, the one end taken over away from bellows is welded with flange 1, weld-ring 3 weld-ring is had to be welded to connect on bellows in the end sleeve of bellows, the external diameter of weld-ring is equal with the external diameter of bellows crest, one metal net cover 6 is enclosed within bellows and weld-ring, on metal net cover, cover has one section of sheathed casing 4, the external diameter of described adapter is less than the external diameter of weld-ring, sheathed casing, one end of metal net cover and weld-ring and the other end of adapter are welded to connect, the cross section of its weld seam is right-angled triangle, the internal diameter of described adapter is equal with the internal diameter of bellows trough, described adapter and weld-ring can be Split type structure and also can be integrally formed.
In the end heeling-in weld seam of described metal net cover, to strengthen the join strength of itself and sheathed casing, weld-ring.
The length of described sheathed casing is that peak separation sum is saved in the thickness of weld-ring and 2 to 4 of bellows.Sheathed casing extends from weld-ring to bellows position the connection of weld-ring and bellows can be prevented impaired, also prevents metal net cover from departing from weld seam simultaneously.
Claims (3)
