Abstract
The utility model relates to a sealing device that is used for boiler and flue junction, include: inner skleeve, outer sleeve, compensating pipe and sealing filler, inside and outside sleeve is steel cavity drum, and the upper end of inner skleeve all is equipped with annular closing cap with the lower extreme of outer sleeve, and the lower part suit of inner skleeve is in the outer sleeve, the compensating pipe is the middle part bellied bobbin that outwards expands, and the coaxial clearance of compensating pipe suit is outside inner skleeve and outer sleeve, and flange joint is passed through with the upper portion of inner skleeve in the upper end of compensating pipe, and the lower extreme of compensating pipe passes through flange joint with the lower part of outer sleeve, sealing filler fills between the inner wall of the inner wall of the inner wall of inner skleeve outer wall and outer sleeve, inner skleeve outer wall and compensating pipe, outer sleeve outer wall and compensating pipe. This device is stopped the boiler and is leaked the smoke pollution environment with the flue connecting portion, protection boiler body and flue have sufficient free expansion gap, improve the sealing device life that is connected of boiler and flue.
Description
Technical field
The utility model relates to sealing device, is specifically related to a kind of sealing device for boiler and flue junction.
Background technology
Conveniently installation requirement, need between boiler with flue to use metal compensator to carry out being connected sealing, compensator is integral installation, installation process is complicated, higher to installation requirement, and the erosive wear that metal compensator is inner and the surperficial existence of outer corrugations is serious, while satisfied axial, transverse direction, angular displacement, compensator surface there will be the problems such as seminess, wearing and tearing, leakage cigarette, and service life shortens.
Utility model content
Not enough for above-mentioned prior art, the utility model provides that a kind of sealing device alternative metals compensator, is arranged on boiler and flue connecting portion for the sealing device of boiler with flue junction, plays and seals and the effect be connected.
The utility model is achieved through the following technical solutions:
For a sealing device for boiler and flue junction, it is characterized in that, described sealing device comprises: inner sleeve, outer sleeve, compensating pipe and airtight and watertight padding; Described inner sleeve and outer sleeve are steel hollow cylinder, and the upper end of described inner sleeve and the lower end of outer sleeve are equipped with annular capping, and the bottom of described inner sleeve is set in outer sleeve; Described compensating pipe is the middle part bobbin that outwards expansion is protruding, described compensating pipe concentric gap is sleeved on outside inner sleeve and outer sleeve, the upper end of described compensating pipe and the top of inner sleeve are by Flange joint, and Flange joint is passed through in the lower end of described compensating pipe and the bottom of outer sleeve; Described airtight and watertight padding be filled in the inwall of inner sleeve outer wall and outer sleeve, inner sleeve outer wall and compensating pipe inwall, between outer sleeve outer wall and the inwall of compensating pipe.
According to above-mentioned device, it is characterized in that, the material of described airtight and watertight padding is ceramic fiber cotton.
Advantageous Effects of the present utility model, the utility model provides a kind of sealing device for boiler and flue junction, the utility model passes through the supporting installation of inner and outer sleeves and compensating pipe, meet the expansion clearance of axis, transverse direction, angular displacement, realized without leaking cigarette, leaking out by Flange joint and filler, and service life can reach more than 10 years.This device stops boiler and flue connecting portion leaks smoke pollution environment; Protection boiler body and flue have enough free wxpansion gaps; Simple installation and outward appearance are neat, solve occur in metal compensator application crackle, wearing and tearing, leakage cigarette, installation and produced problem in safeguarding, improve the connection seal life of boiler and flue.
Accompanying drawing explanation
Fig. 1 is the profile of the utility model structure.
Fig. 2 is the top view of the utility model structure.
Detailed description of the invention
As shown in Figure 1, a kind of sealing device for boiler and flue junction comprises: inner sleeve 1, outer sleeve 2, compensating pipe 3 and airtight and watertight padding 4; Inner and outer sleeves is the hollow cylinder made by roll of steel plate, and the upper end of inner sleeve is provided with annular capping 5, and the lower end of outer sleeve is provided with annular capping 5 ', and the bottom of inner sleeve is set in outer sleeve; Compensating pipe is the middle part hollow bobbin that outwards expansion is protruding, and compensating pipe concentric gap is sleeved on outside inner sleeve and outer sleeve, and the upper end of compensating pipe is connected by flange 6 with the top of inner sleeve, and the lower end of compensating pipe and the bottom of outer sleeve are connected by flange 6 '; Airtight and watertight padding is filled in the inwall of inner sleeve outer wall and outer sleeve, inner sleeve outer wall and the inwall of compensating pipe, between the outer wall of outer sleeve and the inwall of compensating pipe.Preferred airtight and watertight padding is that close, the light ceramic fiber cotton of matter is as filler.
During use, this device is arranged on the junction of boiler and flue, can realize without leaking cigarette, leaking out, protection boiler body and flue have enough free wxpansion gaps; Simple installation and outward appearance are neat, solve occur in metal compensator application crackle, wearing and tearing, leakage cigarette, installation and produced problem in safeguarding, improve the connection seal life of boiler and flue.
Claims (2)
1., for a sealing device for boiler and flue junction, it is characterized in that, described sealing device comprises: inner sleeve, outer sleeve, compensating pipe and airtight and watertight padding; Described inner sleeve and outer sleeve are steel hollow cylinder, and the upper end of described inner sleeve and the lower end of outer sleeve are equipped with annular capping, and the bottom of described inner sleeve is set in outer sleeve; Described compensating pipe is the middle part bobbin that outwards expansion is protruding, described compensating pipe concentric gap is sleeved on outside inner sleeve and outer sleeve, the upper end of described compensating pipe and the top of inner sleeve are by Flange joint, and Flange joint is passed through in the lower end of described compensating pipe and the bottom of outer sleeve; Described airtight and watertight padding be filled in the inwall of inner sleeve outer wall and outer sleeve, inner sleeve outer wall and compensating pipe inwall, between outer sleeve outer wall and the inwall of compensating pipe.
