Description
Technical field
The utility model is related to pipe line compensating devices, more particularly to a kind of non-metal expansion joint.
Background technology
Non-metal expansion joint is widely used in the high temperature flue gas exhausting pipe line such as steam power plant, steel plant, smeltery, nonmetallic
Expansion joint is equipped with covering between two end flanges, and realization is flexible coupling, and guide shell is equipped in covering.The master of existing non-metal expansion joint
Defect is wanted to be：Guide shell be welded on take over or flange endoporus in, easily cause welding deformation；On the other hand, due to guide shell
Entire covering cannot be axially covered, during use, acrobatics, dust are easy to fall between guide shell and covering in cavity, for a long time
Accumulation seriously affects the covering service life and influences the compensation function being flexible coupling.
Invention content
The utility model in view of the deficiencies of the prior art, proposes that one kind being avoided that welding deformation, and be avoided that using process
Middle acrobatics, dust fall into the energy saving high pressure resistant non-metal expansion joint in cavity between guide shell and covering.
The utility model is achieved through the following technical solutions technical goal.
Energy saving high pressure resistant non-metal expansion joint, including right flange, left flange, covering, guide shell；Outside the covering both ends
It turns over, is fixedly connected respectively with right flange left side, left flange right side, constitute collocation structure；The guide shell is arranged in covering
In endoporus；It is theed improvement is that：The guide shell include straight tube, left end the flange that turns up, the guide shell left end turns up method
Orchid is installed between left flange right side, covering left end flange, and straight tube axially penetrates through covering, and right end stretches out right flange right side,
Extension elongation is not less than compensation rate.
In above structure, several gussets are fixedly connected between the guide shell straight tube outer wall, flange right side of turning up, it is described
Gusset is distributed on guide shell straight tube outer wall.
In above structure, the guide shell straight tube outer wall is equipped with refractory layer.
In above structure, the covering inner wall is equipped with steel wire.
The utility model compared with prior art, has the positive effect that：
1, guide shell left end turns up banjo clip mounted between left flange right side, covering left end flange, is connect without being welded on
In pipe or flange endoporus, welding deformation is avoided.
2, straight tube axially penetrates through covering, and right end stretches out right flange right side, and extension elongation is not less than compensation rate, avoids using
Acrobatics, dust are fallen between guide shell and covering in cavity in the process.
3, several gussets are fixedly connected between guide shell straight tube outer wall, flange right side of turning up, significantly improve guide shell knot
Structure intensity, rigidity substantially reduce the deformation under high temperature.
4, guide shell straight tube outer wall is equipped with refractory layer, significantly improves heat-insulated, heat resistance, reduces heat loss, energy saving effect
Fruit is notable.
5, covering inner wall is equipped with steel wire, stressed-skin construction rigidity is significantly improved, to significantly improve pressure-resistant performance.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is A-A sectional views in Fig. 1.
Specific implementation mode
The utility model is described in further detail below according to attached drawing and in conjunction with the embodiments.
Energy saving high pressure resistant non-metal expansion joint shown in attached drawing, including right flange 1, left flange 2, covering 3, guide shell 5, covering
3 inner walls are equipped with steel wire 7；3 both ends of covering are turned up, and are fixedly connected respectively with 1 left side of right flange, 2 right side of left flange, are constituted
Collocation structure；Turn up flange of the guide shell 5 including straight tube, left end, 5 left end of guide shell turn up banjo clip mounted in 2 right end of left flange
Between face, 3 left end flange of covering, straight tube outer wall is equipped with refractory layer 6, and straight tube axially penetrates through covering 3, and it is right that right end stretches out right flange 1
End face, extension elongation are not less than compensation rate.
It is fixedly connected with several gussets 4 between 5 straight tube outer wall of guide shell, flange right side of turning up（In the present embodiment, it is equipped with 4
A gusset 4）, gusset 4 is distributed on 5 straight tube outer wall of guide shell.
