Abstract
The utility model supplies a compensation fixed device for direct buried pipe with high temperature and vacuum. Two section of inner tube is arranged in the device. A compensator of the inner tube is installed at end of every inner tube. An inner-placed fixed pier is provided between the two compensator of the inner tube. A casing is provided at outside of the inner tube. The compensator is arranged at the end of the casing. An outer tube is provided on out wall of the casing. Vacuum zone is formed between the inner tube and the casing. The utility model has the advantages of enhancing vacuum degree at pumping port, prolonging distance between the pumping ports and decreasing cost.
Description
Technical field
The utility model relates to heating equipment, is a kind of high-temperature vacuum directly buried pipeline compensation fixing device.
Background technique
Vacuumize in the conveying heating agent pipeline at directly buried type, every a segment distance, a bleeding point need be set, this bleeding point has a plurality of parts such as working pipe compensator, built-in anchor block, because the link here is more, and working pipe compensator rapid wear, so easily make vacuum leak, make degree of vacuum reduce, increase amount of maintenance, thereby reduce the defeated thermal efficiency of heating agent, cause the certain economic loss.
Summary of the invention
The purpose of this utility model is, a kind of high-temperature vacuum directly buried pipeline compensation fixing device is provided, and makes it have following advantage: it can make the bleeding point place the degree of vacuum height, can prolong the distance between the bleeding point, thereby reduce cost etc.
The utility model is achieved through the following technical solutions for achieving the above object: high-temperature vacuum directly buried pipeline compensation fixing device, it has pipe in two sections, pipe compensator in install the termination of pipe in every section, between the pipe compensator built-in anchor block is installed in two, the outer mounting sleeve of pipe in every section, compensator is installed in the termination of sleeve pipe, and outer tube and outer tube are installed on the sleeve outer wall, forms the region of no pressure between interior pipe and the sleeve pipe.Built-in anchor block is connected with outer tube.Vacuum-pumping tube is installed on the outer tube.Offer the hole on the sleeve pipe, the region of no pressure communicates with the outer tube region of no pressure.Between interior pipe and the sleeve pipe supporting frame is installed.The termination mounting flange and the flange plate of compensator are installed thermal insulating pad between two flange plate.Ring flat-plate is installed in the flange plate outside.Thermal insulation layer is installed on the outer wall of inner tube, and the thermal insulation layer periphery is provided with radiation protective layer.
Advantage of the present utility model is as follows: owing to strengthened degree of vacuum, so can make the distance that is provided with of bleeding point extend to the 1-4 kilometer, when bleeding point place compensator damages gas leakage, still do not influence the proper functioning of service pipe, hot coal is failed thermal efficiency height, and delivery safety is good, functional reliability is high, reduce production costs, easy to maintenance etc.

Embodiment
5 is interior pipes among the figure, pipe compensator 2 in install the termination of pipe 5 in every section, between the pipe compensator 2 built-in anchor block 1 is installed in two, pipe 5 outer mounting sleeves 11 in every section, compensator 4 is installed in the termination of sleeve pipe 11, outer tube 13 and outer tube 14 are installed on sleeve pipe 11 outer walls, are formed region of no pressure 12 between interior pipe 5 and the sleeve pipe 11.Built-in anchor block 1 is connected with outer tube 13.Vacuum-pumping tube 9 is installed on the outer tube 14.Offer hole 6 on the sleeve pipe 11, the region of no pressure communicates between region of no pressure 12 and outer tube 13 and the outer tube 14.Between interior pipe 5 and the sleeve pipe 11 supporting frame 17 is installed.Thermal insulating pad 7 is installed between the termination mounting flange 3 of compensator 4 and flange plate 8, two flange plate.Ring flat-plate 16 is installed in flange plate 8 outsides.On interior pipe 5 outer walls thermal insulation layer 18 is installed, thermal insulation layer 18 peripheries are provided with radiation protective layer 19.Structure shown in the utility model accompanying drawing 2 is installed and used every a segment distance; Structure shown in the accompanying drawing 3 is other segment pipe structure.When pipe 5 has thermal walking in the utility model, its built-in anchor block 1 drives sleeve pipe 11 and moves, the displacement of sleeve pipe 11 is absorbed by compensator 4, the heat transfer of interior pipe 5 is transmitted by ring flat-plate 16, decay rapidly through the sheet asbestos of thermal insulating pad 7 in the middle of flange plate 3 and the flange plate 8 again, make sleeve pipe 11 keep lower interface temperature.When compensator damaged gas leakage, the proper functioning of pipe can not reduce economic loss significantly in not influencing.10 is humidity discharging pipes among the figure.
