Description
Technical field
The utility model is related to pipe expansion joint through walls.
Background technology
Pipe expansion joint through walls depends on boiler tubing and done, and installing space is narrow and small between upper flange and lower flange, in existing skill
In art, generally by the way of directly filling heat-preservation cotton, it is separately fixed on the metal flange of top and the bottom and is reached with nonmetallic composite bed
To insulation purpose.
But during equipment operation, pipeline occur axially, radial displacement, pipe expansion joint moderate soak overall structure through walls will be with
Piping displacement and produce gap, cause internal high temperature flue gas directly to wash away nonmetallic composite bed from clearance leakage, cause nonmetallic
Composite bed surface temperature superelevation, easily damaged at high operating temperatures for a long time and lose insulation effect, reduction of service life, increase dimension
Accomplish this.
The content of the invention
The utility model has flexible smoke shelf structure to solve the above-mentioned problems in the prior art there is provided a kind of
Pipe expansion joint through walls, including the windward flange being fixed on furnace wall plate, are oppositely arranged with the windward flange and are fixed on wall pipe
On leeward flange, radial direction of the spacing along wall pipe between the windward flange and leeward flange opposite face gradually increase
Greatly, it is in the wind between flange and leeward flange opposite face and is sequentially provided with from the inside to the outside:It is solid with windward flange and leeward flange respectively
Connect calmly and width be more than the insulating curtain in gap between the opposite face, the first heat-preservation cotton layer being fixedly connected with leeward flange,
Be set in the first heat-preservation cotton layer periphery the second heat-preservation cotton layer, be fixedly connected with windward flange the 3rd heat-preservation cotton layer, respectively with
Windward flange and leeward flange are fixedly connected and width is more than the covering in gap between the opposite face.
Flexible smoke shelf structure of the present utility model adds the insulating curtain made using ceramic cloth, it is to avoid during equipment operation
Furnace high-temperature flue gas directly washes away pipe expansion joint inside holding through walls;Increase multi-layer heat preserving cotton layer simultaneously, it is to avoid during equipment operation
Nonmetallic composite bed outside wall pipe hyperthermia radiation, better heat preservation, applying working condition more preferably, adds the use longevity of expansion joint
Life, saves the cost of overhaul.
Brief description of the drawings
Fig. 1 is the side sectional view of the utility model expansion joint;
Fig. 2 is the entirety sectional view of the utility model expansion joint.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, pipe expansion joint through walls of the present utility model, including:Windward flange 1, leeward flange 2, every
Hot curtain 3, the first heat-preservation cotton layer 4, the second heat-preservation cotton layer 5, the 3rd heat-preservation cotton layer 6, covering 7, ceramic layer of cloth 8, clip 9, the first steel
Hook 10, the second steel hook 12, stainless steel cylinder 13.
Windward flange 1 is fixed on furnace wall plate 18, and leeward flange 2 is fixed on wall pipe 17, we by windward flange and
Leeward flange side relative to each other is referred to as two opposite faces, along wall pipe radial direction, is referred to as close to wall pipe side
To be interior, the direction away from wall pipe is referred to as outer.Among the utility model, between windward flange and leeward flange opposite face
Radial direction of the spacing along wall pipe gradually increases, that is, the spacing between two opposite faces gradually increases from the inside to the outside.
Insulating curtain 3, the first heat-preservation cotton layer the 4, second heat-preservation cotton the 5, the 3rd heat-preservation cotton of layer layer 6, ceramic layer of cloth 8, covering 7 are set from the inside to the outside
It is in the wind between flange and two opposite faces of leeward flange.
Wherein, insulating curtain 3 by the steel hooks 14 of the both sides on two opposite faces respectively with windward flange 1 and leeward method
Orchid 2 is fixedly connected, and the width of insulating curtain 3 is greater than two gaps to opposite, so when wall pipe is because by thermal expansion, leeward
Flange 2 can correspondingly produce some displacements, will not support insulating curtain.In the present embodiment, insulating curtain employ effect of heat insulation compared with
Good ceramic cloth.
First heat-preservation cotton layer 4 is fixedly connected by the first steel hook 10 with leeward flange 2, and the first steel hook is special U-shaped steel
Hook a, side of the U-shaped steel hook is consistent with the gradient of the opposite face of leeward flange 2, and another side is then plumbness with bottom.
At least one circle iron wire 15 is also cased with the periphery of the first heat-preservation cotton layer 4, the first heat-preservation cotton layer 4 is centered around wall pipe periphery.The
One heat-preservation cotton layer 4 is in leeward 2 displacement of flange, with leeward flange simultaneous displacement.
Second heat-preservation cotton layer 5 is arranged between the first heat-preservation cotton layer 4 and the 3rd heat-preservation cotton layer 6, is set in the first heat-preservation cotton
The periphery of layer 4, the periphery of the second heat-preservation cotton layer 5 is cased with a circle steel band 16 and/or a circle iron wire 15, it as an intermediate layer,
When the first heat-preservation cotton layer 4 is directed away from the direction displacement of windward flange with leeward flange, heat can be stopped, it is to avoid heat
Amount leakage.
3rd heat-preservation cotton layer 6 is fixedly connected with windward flange 1, and the 3rd heat-preservation cotton layer 6 passes through the upwinding of the second steel structure more than 12
Orchid is fixedly connected, and will not be cased with a stainless steel cylinder 13, stainless steel cylinder 13 with leeward flange displacement, the second steel hook outside
In the inner side of the 3rd heat-preservation cotton layer.Ceramic layer of cloth 8 is covered in the periphery of 3rd heat-preservation cotton layer 6, and the periphery of ceramic layer of cloth 8 is equally cased with
At least one circle iron wire 15, then sets covering 7 in the outside of ceramic layer of cloth 8, covering 7 by two circle clips respectively with upwinding
Orchid is fixedly connected with leeward flange, although covering width is more than gap between two opposite faces, but in order to avoid leeward flange
Covering is pullled in displacement, causes the clip being located on windward flange to be subjected to displacement, therefore flange of being in the wind is provided with a circle limit
The positioning iron wire 11 of its displacement is made, the iron wire is located between two circle clips, can limit the clip court being fixed on windward flange
Displacement is carried out to the clip being fixed on leeward flange.
Flexible smoke shelf structure is formd by said structure to be in the wind between flange and leeward flange.When equipment is run, wear
Wall coil will be subjected to displacement, and the first heat-preservation cotton layer and leeward flange also be will move with, but internal increased insulating curtain is directly obstructed
High-temperature flue gas, and increased 3rd heat-preservation cotton layer will not be moved due to being fixed with windward flange, still play wall pipe insulation
Effect, while preventing nonmetallic composite bed directly by wall pipe hyperthermia radiation.
Specific embodiment above is only to illustrate design of the present utility model, and one of ordinary skill in the art exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
