Abstract
The present invention provides a compensating and fixing device for a high temperature vacuum direct buried pipeline, which is provided with two inner pipes, wherein each inner pipe is provided with a compensating device of a work pipe. Fixing piles of an inner arranging type are arranged on outer walls of the inner pipes between the two compensating devices of a work pipe. Each inner pipe is provided with a sleeve pipe. The end of each sleeve pipe is provided with a compensating device which is arranged on the outer sides of the compensating devices of a work pipe. Each sleeve pipe is provided with an outer pipe which is connected with a vacuum pipe. Each sleeve pipe is connected with the vacuum pipe. The compensating and fixing device can separate the periphery of the compensating devices of a work pipe and the work pipe into two independent vacuum areas. When the compensating devices are damaged, the other vacuum areas can not be influenced to enable the damage to be minimum, and the maintenance is convenient.
Description
Technical field
The present invention relates to heating equipment, is a kind of high-temperature vacuum directly buried pipeline compensation fixing device.
Background technique
The pipeline of delivering vapor and hot water, generally adopt dual mode insulation: a kind ofly at pipeline external surface thermal insulation layer is set, another kind is to vacuumize between interior pipe and outer tube.Because the mode that vacuumizes between the inner and outer pipes can make thermal losses reduce significantly, so be the using method of heat supply field first-selection.But this mode that vacuumizes is in long distance a bleeding point to be set, and does not have seal protection between compensator and the working pipe, if the working pipe compensator damages, just the vacuum of whole pipe is destroyed, easily causes bigger economic loss.
Summary of the invention
The objective of the invention is, a kind of high-temperature vacuum directly buried pipeline compensation fixing device is provided, it can will be divided into two independently regions of no pressure around working pipe compensator and the working pipe, when compensator damages, can not influence other region of no pressure, make loss reduce to minimum, easy to maintenance.
The present invention for achieving the above object, be achieved through the following technical solutions: high-temperature vacuum directly buried pipeline compensation fixing device, it has in two sections pipe, and pipe is gone up installment work pipe compensator in every section, and built-in anchor block is installed on the outer wall of inner tube between the two working pipe compensators, pipe is gone up mounting sleeve in every section, compensator is installed in every section sleeve pipe termination, and compensator places the outside of working pipe compensator, on every section sleeve pipe outer tube is installed, outer tube is connected with vacuum tube, and sleeve pipe is connected with vacuum tube.The termination mounting flange of compensator is installed thermal-protective coating between two flange plate.Between interior pipe and sleeve pipe, supporting frame is installed.Thermal insulation layer is installed on the outer wall of inner tube, and the thermal insulation layer periphery is provided with radiation protective layer.The two ends of built-in anchor block are connected with outer tube respectively.
The present invention has following advantage: realized Connector Environments around working pipe compensator and the working pipe is isolated into two independent vacuum districts, promptly form region of no pressure A and region of no pressure B, when the compensator on working pipe compensator or the sleeve pipe damages, only need to destroy region of no pressure B less than about 10 meters, can not influence other region of no pressure, keep in repair efficient and convenient, the loss little, for the user provides bigger convenience.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention; Accompanying drawing 2 is C-C amplification profile structural representations in the accompanying drawing 1; Accompanying drawing 3 is D-D amplification profile structural representations in the accompanying drawing 1.
Embodiment
6 is interior pipes among the figure, installment work pipe compensator 2 on the pipe 6 in every section, built-in anchor block 1 is installed on the outer wall of inner tube between the two working pipe compensators 2, pipe 6 mounting sleeves 4 in every section, compensator 7 is installed in every section sleeve pipe 4 terminations, and compensator 7 places the outside of working pipe compensator 2, and outer tube 8 is installed on every section sleeve pipe 4, outer tube 8 is connected with vacuum tube 5, and sleeve pipe 4 is connected with vacuum tube 9.Thermal-protective coating 10 is installed between termination mounting flange 3, two flange plate 3 of compensator 7.Supporting frame 12 is installed between interior pipe 6 and sleeve pipe 4.On interior pipe 6 outer walls thermal insulation layer 11 is installed, thermal insulation layer 11 peripheries are provided with radiation protective layer 13.The two ends of built-in anchor block 1 are connected with outer tube 8 respectively.The heat supply pipeline that the present invention is used to vacuumize is installed about 100 meters left and right sides distances.Structure shown in Figure 2 is installed every a segment distance, and structure shown in Figure 3 is other segment pipe structure.When working pipe of the present invention had thermal walking, built-in anchor block 1 drove sleeve pipe 4 and moves, and the displacement of sleeve pipe 4 is absorbed by compensator 7, and the heat transfer of working pipe decays rapidly through the sheet asbestos of flange intermediate thermal insulating layer 10, made sleeve pipe 4 keep lower interface temperature.When working pipe compensator 2 damages, only need to destroy B district vacuum state, can keep in repair or change parts very easily quickly, reduced economic loss, provide bigger convenience to the user.The not detailed structure of describing of the present invention is a known technology.
