Description
Technical field
The present invention relates to a kind of high temperature expansion bellow heat-barrier material uniform stressed structures, are specifically related to a kind of high temperature wave
Line expansion joint heat-barrier material uniform stressed structure.
Background technique
High temperature expansion bellow is used to compensate the axial displacement or radial displacement of pipeline, and structure generally comprises bellows,
It is equipped with adapter tube at the both ends of bellows, is respectively equipped with ring flat-plate in the outer end of adapter tube, is equipped with diversion pipe, ripple in the inner ring of ring flat-plate
Heat-barrier material is equipped in the cavity that pipe, diversion pipe and ring flat-plate are surrounded.When deformation occurs for bellows, heat-barrier material be will receive
Compression, heat-barrier material is sprung back after compression disappears, and when compressed due to heat-barrier material, the pressure born close to the position of ring flat-plate is big,
The position of remote high ring flat-plate is pressurized small, and the pressure of each section of receiving of heat-barrier material is uneven, be easy fatigue close to the position of ring flat-plate and,
It follows the string, declines heat insulation.
Summary of the invention
It wears and is heated the technical problem to be solved by the present invention is to overcome prior art heat-barrier material, be pressurized non-uniform lack
It falls into, a kind of high temperature expansion bellow heat-barrier material uniform stressed structure is provided.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of high temperature expansion bellow heat-barrier material
Left adapter tube and right adapter tube is respectively welded in uniform stressed structure, including outer tube, the both ends of the outer tube, and the middle part of the outer tube is wave
Line pipe, the inner ring of the left adapter tube extend internally the first diversion pipe of welding, and the inner ring of the right adapter tube extends internally welding second
The outside of diversion pipe, first diversion pipe and the second diversion pipe is arranged heat conducting pipe, the outside spacers welding of the heat conducting pipe every
Plate, filling with insulation material between the heat conducting pipe and outer tube, bellows, the both ends of the heat conducting pipe symmetrically open up movable port,
The inner end of first diversion pipe and the inner end of the second diversion pipe, which are run through, opens up through-hole, and bolt is installed in through hole, the bolt
Screw rod passes through movable port and through-hole is fixed with nut tightening；Gap length between first diversion pipe and the second diversion pipe
Equal to the gap length of the both ends activity port of heat conducting pipe；The plate body that the partition is located at movable passage port disconnects installation.
Further, the width of the movable port is identical as the screw diameter length of bolt.
Compared with the prior art, the invention has the beneficial effects that：A kind of high temperature expansion bellow heat-barrier material uniformly by
Power structure, heat conducting pipe can be reduced or even be fallen into pipeline after avoiding heat-barrier material from being worn, and heat conducting pipe cooperates partition, so that first
The heat of diversion pipe and the second diversion pipe is more uniform when being transmitted to heat-barrier material, and each section of stress of heat-barrier material can be made equal
Even, the elastic wound that is not easy is lost, and compared to the hot uniform treatment means of existing high temperature expansion bellow, more coordinates in structure, is beautiful,
In adjusting more rationally, while it is more uniform to transmit heat.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to figs. 1 to known to Fig. 2：A kind of high temperature expansion bellow heat-barrier material uniform stressed structure, including outer tube 1, institute
Left adapter tube 2 and right adapter tube 3 is respectively welded in the both ends for stating outer tube 1, and the middle part of the outer tube 1 is bellows 4, the left adapter tube 2
Inner ring, which extends internally, welds the first diversion pipe 5, and the inner ring of the right adapter tube 3, which extends internally, welds the second diversion pipe 6, and described first
The outside of diversion pipe 5 and the second diversion pipe 6 is arranged heat conducting pipe 7, and the outside spacers welding diaphragm 8 of the heat conducting pipe 7 is described thermally conductive
Filling with insulation material 9 between pipe 7 and outer tube 1, bellows 4, the both ends of the heat conducting pipe 7 symmetrically open up movable port 10, described
The inner end of first diversion pipe 5 and the inner end of the second diversion pipe 6, which are run through, opens up through-hole, and bolt 11, the bolt 11 are installed in through hole
Screw rod pass through movable port 10 and through-hole is tightened with nut 12.
Gap length between first diversion pipe 5 and the second diversion pipe 6 is equal to the both ends activity port 10 of heat conducting pipe 7
Gap length, convenient for the movement of the first diversion pipe 5 and the second diversion pipe 6.
The plate body that the partition 8 is located at movable port 10 disconnects installation, convenient for the movement of 11 end of bolt.
The width of the activity port 10 is identical as the screw diameter length of bolt 11, reduces gap, reduces impurity and falls.
The principle of the present invention and advantage：In use process, bellows 4 is stretched, then the first diversion pipe 5 and the second diversion pipe 6
It is displaced outwardly, when mobile, the end of bolt 11 generates displacement on movable port 10, and heat conducting pipe 7 is always by heat-barrier material 9
It is supported between heat conducting pipe 7, outer tube 1 and bellows 4, reduces and heat-barrier material 9 is even avoided to fall（In order to avoid heat-barrier material 9
It is worn, the end of bolt 11 can be got rid of, and realize heat-barrier material 9 with heat conducting pipe 7 without friction）, while outside heat conducting pipe 7
The partition 8 of side, so that 9 thermally equivalent of heat-barrier material, and by the effect of heat conducting pipe 7, the first diversion pipe 5 and the second diversion pipe 6
Heat it is more uniform when being transmitted to heat-barrier material 9.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
