Abstract
A high-temperature corrugated pipe compensator is used for compensating expansion with heat and contraction with cold of a pipeline. The heat insulation sleeve comprises a guide cylinder (6), a first sleeve (3) and a second sleeve (10) are respectively inserted into two ends of the guide cylinder, the first sleeve sequentially passes through a first corrugated pipe (4), the guide cylinder and a second corrugated pipe (9) are in seal welding with the second sleeve, a first heat insulation sleeve (2) is fixedly inserted into the first sleeve, a second heat insulation sleeve (8) is fixedly inserted into the second sleeve, a gap is reserved between the first heat insulation sleeve and the second heat insulation sleeve, flexible heat insulation materials (7) are filled into the gap, and the vertical cross section of the gap is in a shape like a Chinese character 'tu'. The corrugated pipe has the advantages that the left part and the right part of the flexible heat insulation material have radial force, and can keep sealing with the first heat insulation sleeve and the second heat insulation sleeve, so that the corrugated pipe is not damaged by high temperature; the flexible heat insulation material is sealed and is not easy to run off; the guide cylinder enables the first sleeve and the second sleeve to be coaxial, and when the first sleeve and the second sleeve displace, the flexible heat-insulating material is little worn.
Description
Technical Field
The invention relates to a corrugated pipe compensator which is used for compensating expansion with heat and contraction with cold of a pipeline.
Background
The key part of the corrugated pipe compensator is a corrugated pipe, and the compensator is applied to a high-temperature pipeline and is easy to cause fatigue damage of the corrugated pipe due to the high-temperature action of a medium. In order to protect the corrugated pipe, the existing compensator is provided with a heat insulation layer between the corrugated pipe and a medium, and due to expansion with heat and contraction with cold of the pipeline, the material of the heat insulation layer can be lost due to displacement, so that the heat insulation effect is greatly reduced.
Disclosure of Invention
In view of the above problems, the present invention provides a high temperature corrugated pipe compensator, which has good heat insulation performance to protect the corrugated pipe from high temperature; during operation, the abrasion of the heat insulation layer material can be reduced, and the heat insulation performance can be maintained.
The technical scheme of the invention is that the high-temperature corrugated pipe compensator comprises a guide cylinder 6, a first sleeve 3 and a second sleeve 10 are respectively inserted at two ends of the guide cylinder, the left end of a first corrugated pipe 4 is hermetically welded with the first sleeve, the right end of a second corrugated pipe 9 is hermetically welded with the second sleeve, two ends of the excircle of the guide cylinder are hermetically welded with the right end of the first corrugated pipe and the left end of the second corrugated pipe respectively, it is characterized in that a first heat insulation sleeve 2 is fixedly inserted in the first sleeve, a second heat insulation sleeve 8 is fixedly inserted in the second sleeve, a gap is reserved between the first heat insulation sleeve and the second heat insulation sleeve, a flexible heat insulation material 7 is filled in the gap, the vertical section of the gap is in a convex shape, the right part of the first heat insulation sleeve is attached to the left part of the flexible heat insulation material, the left part of the second heat insulation sleeve is attached to the right part and the bottom of the flexible heat insulation material, and the wall body of the second heat insulation sleeve attached to the bottom of the flexible heat insulation material extends into the first heat insulation sleeve.
The high-temperature corrugated pipe compensator has the advantages that the flexible heat insulation material is clamped and pressed into a convex shape by the first heat insulation sleeve and the second heat insulation sleeve, the left part and the right part of the flexible heat insulation material have radial force, even if the first heat insulation sleeve and the second heat insulation sleeve axially move back to back, the flexible heat insulation material can still be tightly contacted with the first heat insulation sleeve and the second heat insulation sleeve in the radial direction, the sealing performance is kept, and the first corrugated pipe and the second corrugated pipe are not damaged by high temperature; the flexible heat insulation material is sealed by the first heat insulation sleeve and the second heat insulation sleeve, and the flexible heat insulation material is not easy to run off; the guide cylinder enables the first sleeve and the second sleeve to be coaxial, and when the first sleeve and the second sleeve displace, the flexible heat-insulating material is little worn.
