Technical field
The present invention relates to a kind of heat-insulated fixing bracket of direct-buried steam pipeline, especially a kind of prefabricated direct-buried jet chimney is received
The heat-insulated fixing bracket of rice.
Background technology
Currently, direct-buried steam pipeline fixing bracket mostly uses the structure that core pipe is directly connected to the effective concentric reducer of set, heat
It can directly spread out of, increase pipe network heat waste, destroy the outer anti-corrosion of pipeline, the heat pair for reducing the service life of pipe network, and shedding
Surrounding vegetation causes detrimental effects, so generally requiring buried, increases earth excavation and construction period.
Invention content
The purpose of the present invention is overcoming the deficiencies in the prior art, provide a kind of prefabricated direct-buried jet chimney nanometer every
Thermosetting fixed rack solves the problems, such as the support bracket fastened heat bridge of conventional direct-buried steam pipeline, the pipeline heat expansion in equilibrium vapor pipe network
While stress, the generation of heat bridge is effectively reduced.
According to technical solution provided by the invention, the prefabricated direct-buried jet chimney nano heat-insulating fixing bracket, including set
First layer outer tube in core pipe and the second layer outer tube being sheathed on the outside of first layer outer tube, it is characterized in that：It is described
First layer outer tube is formed by connecting by outer tube on the inside of outer tube on the outside of the first layer at both ends and intermediate first layer, is located at both ends
First layer on the outside of outer tube connect respectively by the first concentric reducer with second layer outer tube；It is connected in the core pipe second largest
Microcephaly, the second concentric reducer connect outer tube on the inside of core pipe and first layer；Outer tube and the second concentric reducer on the inside of the first layer
Between weld inner side baffle, the outer side shield of welding on outer tube, is arranged between inner side baffle and outer side shield on the outside of the first layer
Heat-barrier material.
Further, nanometer cotton is filled between the first layer outer tube and core pipe.
Further, nanometer cotton is filled between magnetic tube outside the first layer outer tube and the second layer.
Further, the heat-barrier material uses 2 layers of asbestos board and 3 layers of nanometer cotton.
Further, the inner side baffle and outer side shield are annular shape.
Further, the internal diameter of the annulus is more than the outer diameter of core pipe, is less than the outer diameter of first layer outer tube；Outside annulus
Diameter is more than the outer diameter of first layer outer tube, is less than the outer diameter of second layer outer tube.
Further, reinforced using side of body plate between the outer side shield and first layer outer tube.
It is solid to solve conventional direct-buried steam pipeline for prefabricated direct-buried jet chimney nano heat-insulating fixing bracket of the present invention
The heat bridge problem of fixed rack effectively reduces the generation of heat bridge in equilibrium vapor pipe network while pipeline heat expansion stress.
Description of the drawings
Fig. 1 is the prefabricated direct-buried support bracket fastened structural schematic diagram of jet chimney nano heat-insulating of the present invention.
Specific implementation mode
With reference to specific attached drawing, the invention will be further described.
As shown in Figure 1：The prefabricated direct-buried jet chimney nano heat-insulating fixing bracket includes core pipe 1, outer on the outside of first layer
Casing 2, the first concentric reducer 3, outer side shield 4, second layer outer tube 5, heat-barrier material 6, inner side baffle 7, first layer inside housing
Pipe 8, second concentric reducer 9 etc..
As shown in Figure 1, prefabricated direct-buried jet chimney nano heat-insulating fixing bracket of the present invention, including it is sheathed on core pipe 1
On first layer outer tube and the second layer outer tube 5 that is sheathed on the outside of first layer outer tube, first layer outer tube is by both ends
Outer tube 2 and intermediate first layer inside outer tube 8 are formed by connecting on the outside of first layer, are located at outer tube on the outside of the first layer at both ends
2 are connect by the first concentric reducer 3 respectively with second layer outer tube 5；The second concentric reducer 9, the second size are connected in the core pipe 1
Outer tube 8 on the inside of first 9 connection core pipe 1 and first layer；It is welded between outer tube 8 and the second concentric reducer 9 on the inside of the first layer
Inner side baffle 7, the outer side shield 4 of welding on outer tube 2, is arranged heat-insulated between inner side baffle 4 and outer side shield 7 on the outside of the first layer
Material 6；The second layer outer tube 5 is stepping up the heat-barrier material 6 between outer side shield 4 and inner side baffle 7.
Nanometer cotton, the magnetic tube 5 outside first layer outer tube and the second layer are filled between the first layer outer tube and core pipe 1
Between fill nanometer cotton.
The heat-barrier material 6 uses 2 layers of asbestos board and 3 layers of nanometer cotton.
The inner side baffle 7 and outer side shield 4 are annular shape, and the internal diameter of annulus is more than the outer diameter of core pipe 1, is less than first
The outer diameter of layer outer tube；The outer diameter of annulus is more than the outer diameter of first layer outer tube, is less than the outer diameter of second layer outer tube 5.
