Fig. 1 is that double-deck chimney includes urceolus 1, sets up at the inside inner tube 2 of urceolus 1, and fig. 2 is that telescopic compensator includes sleeve 3, and wherein the front end embedding inner tube 2's of sleeve 3 inside, sleeve 3 is straight among the prior art, and the welding is carried out after embedding inner tube 2, but in industrial production, double-deck chimney is than higher, and the staff's operation is very inconvenient during the welding, and the danger is than higher. The utility model discloses set up sealing connection structure between inner tube 2 and sleeve 3, sealing connection structure is including setting up the glue film between sleeve 3 and inner tube 2, and it is shown in figure 1 that the surface at inner tube 2 sets up outside bellied first protruding muscle 21 simultaneously, and 3 front ends of sleeve set up the concave muscle 31 to the sleeve 3 inside sunken, the internal surface and the glue film of first protruding muscle 21 are connected, the surface and the glue film of concave muscle 31 are connected. The below of concave muscle 31 is provided with the protruding muscle 32 of second, first protruding muscle 21, the protruding muscle 32 of second, concave muscle 31 are the ring annular structure, concave muscle 31, the protruding muscle 32 of second all distribute in sleeve 3's periphery, first protruding muscle 21 sets up the periphery at inner tube 2. During installation, the front end of the sleeve 3 extends into the inner barrel 2, the concave rib 31 is connected with the inner barrel 2 through a glue layer, and the first convex rib 21 is connected with the sleeve 3 through a glue layer as shown in fig. 3. The utility model discloses it is less to increase the circularity error that first protruding muscle 21 can make drum 2, increases drum 2's compressive strength simultaneously, and concave muscle 31 and the protruding muscle 32 of second can make sleeve 3's circularity be convenient for install better, can also strengthen sleeve 3's compressive strength simultaneously.

As a preferred scheme, a first glue injection hole 211 is formed in the first convex rib 21, a second glue injection hole 311 is formed in the concave rib 31, the first glue injection hole 211 and the second glue injection hole 311 are multiple, the first glue injection hole 211 and the second glue injection hole 311 are distributed at equal intervals, the aperture of the first glue injection hole 211 and the aperture of the second glue injection hole 311 are not smaller than 10mm, glue is injected between the sleeve 3 and the inner cylinder 2 through the first glue injection hole 211 and the second glue injection hole 311 after the sleeve 3 is embedded into the inner cylinder 2, glue can be uniformly distributed in a gap between the inner cylinder 2 and the sleeve 3 through the multiple glue injection holes, and during specific operation, a high-pressure glue gun is aligned to the glue injection holes to inject a sealant. When the sealant flows out from a hole, the next hole is replaced, and the glue can be uniformly distributed between the inner barrel 2 and the sleeve 3. The utility model discloses only need insert sleeve 3 and pass through injecting glue hole injecting glue in inner tube 2, can accomplish the installation of telescopic compensator and double-deck chimney, novel structure, convenient operation is convenient for maintain, implements effectually, and installation stability is high. The glue in the embodiment is blue-light brand L995 engineering bonding silicone adhesive or bonding silicone adhesive with the same structure.

Example 2

The distance between the concave ribs 31 positioned at the top of the sleeve 3 and the top end of the sleeve 3 is 10-100mm, and the distance between the concave ribs 31 positioned at the bottom of the sleeve 3 and the top end of the sleeve 3 is 60-150 mm. This embodiment uses 2 concave muscle 31 as an example, press first concave muscle 31 at distance sleeve top 50mm department, locate to establish second concave muscle 31 apart from sleeve top 100mm, sleeve 3 inserts 2 inside backs in inner tube, first convex muscle 21 is located between first concave muscle 31 and the second concave muscle 31, at first carry out the injecting glue in the second injecting glue hole 311 on the second concave muscle 31 that is located the below, treat sealed glue from just near a hole outflow, trade a hole, take the second concave muscle 31 and all annotate the back, begin to carry out injecting glue in first convex muscle 21, at last the downthehole injecting glue of second injecting glue on the first concave muscle 31 that is located the top. Through the mode of 3 layers of injecting glue for the injecting glue is more even, makes sleeve 3 and inner tube 2 bond inseparabler. In addition, when the glue between the inner barrel 2 and the sleeve 3 is aged and the like, the glue can be continuously injected from the glue injection hole, so that the problems of large gap between the inner barrel and the sleeve, loose sealing, easy water and gas leakage and convenient later-stage repair can be solved.
