Description
Technical field
The utility model belongs to utilidor technical field, and in particular to a kind of constitutionally stable insulating tube.
Background technology
Heating power insulating tube is applied in heating power heating and production process, and existing thermodynamic transport pipe will according to different heating
Ask, given and realized using different types of insulating tube.Existing thermo-insulating pipe line is generally given when implementing by the way of underground preburied
Realization is given, during the use of insulating tube, particularly during the use of the larger thermo-insulating pipe line of latus rectum, due to insulating tube
The extruding to outer tube wall of " ectonexine " insulation construction and upper strata landfill material, easily cause, the deformation of insulating tube base insulating layer, outside
Layer pipe can produce substantial deviation relative to the position of inner tube, therefore, make insulation Quality Down, insulating tube service life reduction.For upper
Situation is stated, in the prior art, is employed on insulating tube both sides, the mode that ectonexine pipe is welded, which is given, to be solved, but this
Method is in implementation process, on the one hand, due to the two ends for being supported on insulating tube of insulating tube, therefore when being used for a long time, easily causes
Central region is deformed.On the other hand, because the area of two ends fixation welding is smaller, and because insulating tube is in perishable ring for a long time
Under border, therefore, situations such as easily snapping.Therefore, existing heavy caliber insulating tube in use, heat-insulation layer is yielding,
Stability is poor after long-term use for heat insulation effect, maintenance and use cost is increased, thus develop a kind of insulating tube to solve on
The problem of stating, has great importance.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provide a kind of constitutionally stable insulating tube.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of constitutionally stable insulating tube, including interior steel pipe, insulating foam layer and outer protection tube, the heat-insulation layer are located at described
Between interior steel pipe and the outer protection tube, distance arrangement is propped up provided with multiple annulars at regular intervals between the interior steel pipe and outer protection tube
Support, the ring holder, which includes radial arrangement on an annular solid, the inner ring face of the annular solid, multiple supporting plates, institute
Stating the top of supporting plate has arc support, and the arc support is fitted with the outside wall surface of the interior steel pipe, the annular
The outer ring of body fits with the internal face of the outer protection tube and contacted.
It is preferred that, the cross section of the annular solid is platy structure, and the arc support is arc plate-like tile.
It is preferred that, the ring holder is made using steel.
The constitutionally stable insulating tube of the utility model, by pacifying in the insulating foam layer between working steel tube and outer protection tube
Support is filled to support, so as to provide more stable support inside insulating tube, the non-deformability of body is improved, extended
The service life of insulating tube, reduces use and the maintenance cost of overall heating power transfer tube.
Brief description of the drawings
Fig. 1 is the structural representation of constitutionally stable insulating tube of the present utility model；
Fig. 2 is the schematic diagram of ring holder of the present utility model.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figure 1-2, a kind of constitutionally stable insulating tube 100, including interior steel pipe 1, insulating foam layer (not shown) and
Outer protection tube 2, the heat-insulation layer is located between the interior steel pipe and the outer protection tube, by certain between the interior steel pipe and outer protection tube
Spacing distance arrangement is provided with multiple ring holders 3, and the ring holder includes annular solid 30, the annular solid it is interior
There being radial arrangement on circle face is spaced default distance between multiple supporting plates 31, multiple supporting plates, the top tool of the supporting plate
Have arc support 32, the arc support and the outside wall surface of the interior steel pipe are fitted and connected, the outer ring of the annular solid with
The internal face of the outer protection tube fits contact.
Wherein, the heat-insulation layer is foaming thermal-insulating, after being filled between the interior steel pipe and the outer protection tube, by institute
Ring holder 3 is stated to wrap inside heat-insulation layer.
Further, as anti-provided with aluminium foil between the outer surface of the heat-insulation layer described in one embodiment and the outer protection tube
Layer 4 is penetrated, the aluminium foil reflecting layer is connected with the appearance face contact type of the heat-insulation layer, and is fixed on the interior of the outer protection tube in advance
On wall.During using this structure, the annular solid 30 of ring holder 3 is in contact with the inner surface in aluminium foil reflecting layer 4.
It is preferred that, the cross section of the annular solid is platy structure, and the arc support is arc plate-like tile, described
Supporting plate is fan shape structure.
It is preferred that, the ring holder is used after steel making after each part, then by being welded together, i.e. institute
Annular solid is stated to form described ring holder with supporting plate, arc support to be welded together after making respectively.Institute
The area of space 34 for being formed with and being passed through for interior steel pipe 1 on the inside of arc support is stated, is welded to connect after being passed through for interior steel pipe 1
Together.
Of course, the inner surface of the interior steel pipe is provided with anticorrosive coat, the outer protection tube can be PE pipes, HDPE pipes and
Steel pipe etc. is realized, is not limited specifically.
During making, multiple ring holders are contacted and are welded on interior steel pipe with interior steel pipe by curved portions, so
Inwall is provided with the outer protection tube in the aluminium foil reflecting layer in rear enclosure, foaming operation is then carried out on foaming platform, by foaming material
Between material injection outer protection tube and interior steel pipe, foaming is completed, you can realize constitutionally stable insulating tube described in the utility model.
It is connected due to being located at the ring holder, and with interior steel-pipe welding, so that in serving and being supported in outer protection tube
On steel pipe, so in underground in use, can effectively prevent outer protection tube from being deformed by external pressure, cause the insulation of insulating tube
Layer deformation, and influence heat insulation effect.
The constitutionally stable insulating tube of the utility model, by pacifying in the insulating foam layer between working steel tube and outer protection tube
Support is filled to support, so as to provide more stable support inside insulating tube, the non-deformability of body is improved, extended
The service life of insulating tube, reduces use and the maintenance cost of overall heating power transfer tube.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
