Abstract
The utility model relates to an expansion joint with labyrinth sealing diversion sleeve and includes a flange at each end, a connecting pipe at each end, a diversion sleeve fixed on the flange at one end, a compensator arranged between the two connection pipes; the utility model is characterized in that a suspension loop is connected with the flange at the other end; a flexible diversion sleeve is sleeved around the diversion sleeve and one end of the flexible diversion sleeve is hooked on the suspension loop; the annular cavities between the connecting pipes at the both ends, the compensator, the diversion sleeve and the flexible diversion sleeve are filled with heat insulating material; an internal diversion sleeve is arranged in the diversion sleeve and the flexible diversion sleeve and is connected with the flange for upstream medium; A trim packing is arranged between the end part of the internal diversion sleeve and the diversion sleeve. The utility model has the advantages that the labyrinth structure prevents the high-temperature medium or wearing medium from entering the internal surface of compensator; the medium can flow in the pipe with the least resistance, which prolongs the service life of the product and decrease the possibility of pipe accident.
Description
Technical field
The utility model belongs to a kind of pipeline compensator, particularly a kind of labyrinth sealing water conservancy diversion cover expansion joint.
Background technique
Existing pipe wear is than under the serious situation, smoke wind pipe etc. for example, the compensator life-span is reduced greatly, or the high cigarette wind of temperature sees through poorly sealed water conservancy diversion nested structure and be drilled into bellows or non-metal compensator inside, make bellows destroyed by high temperature.
The model utility content
The purpose of this utility model provides a kind of labyrinth sealing water conservancy diversion cover expansion joint, and it comprises that the medium that stops high temperature and galling enters into the internal surface of compensator, prolongs the working life of product, reduces the pipeline possibility of accident occurrence.
The purpose of this utility model is achieved by the following technical solution: it comprises two end flange, two pipe nipples, be fixed on the water conservancy diversion cover on the end flange, between two pipe nipples, connect compensating part, it is characterized in that: be connected with link at the other end flange, at the movable water conservancy diversion cover of the outside suit of water conservancy diversion cover, movable water conservancy diversion overlaps an end hook and hangs on the link, at two pipe nipples, compensating part, assembling thermal-protective material in the ring cavity between water conservancy diversion cover and the movable water conservancy diversion cover, water conservancy diversion cover in the assembling in water conservancy diversion cover and movable water conservancy diversion cover, interior water conservancy diversion cover is connected on the flange of MEDIA FLOW upstream direction, between the end and the water conservancy diversion of interior water conservancy diversion cover overlap sealing filler is set.
The utility model has the advantages that: the structure of mazy type setting stops the medium of high temperature and galling to enter into the internal surface of compensator, allows medium advance at the passage of pipeline along the resistance minimum, prolongs the working life of product, reduces the pipeline possibility of accident occurrence.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment:
See Fig. 1, concrete structure is as follows: two end flange 1,10 weld together with two pipe nipples 2 respectively, compensator 7 is connected and constitutes the trombone slide structure between two pipe nipples 2, compensator 7 can adopt existing wavy metal form of tubes, also can adopt nonmetallic telescopic dry goods, as silica gel cloth, wired glass fibre cloth etc.Water conservancy diversion cover 5 is set in trombone slide structure inboard, and water conservancy diversion cover 5 is welded on the end flange 1, and water conservancy diversion cover 5 is decided according to temperature is different with the distance between the trombone slide structure.At the movable water conservancy diversion cover 6 of the outside suit of water conservancy diversion cover 5, movable water conservancy diversion overlaps 6 ends hook ring is set, and is connected with the link 9 that is connected with hook ring on the other end flange 10.Stuffed heat insulated heat-preservation cotton 8 (or other thermal insulating material) in the ring cavity between two pipe nipples 2, compensating part 7, water conservancy diversion cover 5 and movable water conservancy diversion cover 11.Water conservancy diversion cover 11 in the assembling in water conservancy diversion cover 5 and movable water conservancy diversion cover 6, interior water conservancy diversion cover 11 is connected on the flange 10 of MEDIA FLOW upstream direction, assembling sealing filler 12 between the end of interior water conservancy diversion cover 11 and water conservancy diversion cover 5, water conservancy diversion overlapped the baffle ring 3 of 11 ends and water conservancy diversion and overlaps between the baffle ring 4 on 5 in sealing filler 12 was set at.This maze-type structure makes pipeline internal medium when direction shown in the figure flows, and the passage that medium enters into compensator inside just could arrive along maze-type structure, and difficulty is very big, has protected compensator like this.
Claims (2)
1. a labyrinth sealing water conservancy diversion overlaps expansion joint, it comprises two end flange, two pipe nipples, be fixed on the water conservancy diversion cover on the end flange, the compensating part of between two pipe nipples, assembling, it is characterized in that: be connected with link at the other end flange, at the movable water conservancy diversion cover of the outside suit of water conservancy diversion cover, movable water conservancy diversion overlaps an end hook and hangs on the link, at two pipe nipples, compensating part, assembling thermal-protective material in the ring cavity between water conservancy diversion cover and the movable water conservancy diversion cover, water conservancy diversion cover in the assembling in water conservancy diversion cover and movable water conservancy diversion cover, interior water conservancy diversion cover is connected on the flange of MEDIA FLOW upstream direction, between the end and the water conservancy diversion of interior water conservancy diversion cover overlap sealing filler is set.
2. labyrinth sealing water conservancy diversion according to claim 1 cover expansion joint is characterized in that: in sealing filler is set between the baffle ring of water conservancy diversion cover end and the baffle ring that water conservancy diversion puts.
