Description

Technical Field

[0001] This utility model relates to the field of heat shrink sleeve technology, specifically a heat shrink sleeve with high tensile properties. Background Technology

[0002] Heat shrinkable sleeves are heat-shrinkable anti-corrosion materials designed for corrosion protection of welded joints in buried and overhead steel pipelines and for insulation repair of insulated pipelines. During installation, heating causes the base material to shrink radially, while the internal composite adhesive layer melts, tightly wrapping around the repair area to form a robust anti-corrosion layer. Heat shrinkable sleeves are widely used in steel pipeline repair applications in industries such as petroleum, natural gas, chemical, and urban construction, providing reliable corrosion protection.

[0003] After the heat shrink sleeve is installed, during subsequent use, the connection of the heat shrink sleeve may become loose due to pipe shaking, or the heat shrink sleeve may break due to being stretched because the connection between the heat shrink sleeve and the pipe is too tight. Utility Model Content

[0004] The purpose of this invention is to provide a heat shrink sleeve with high tensile properties to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat shrink sleeve with high tensile properties, comprising: a first tube and a second tube, and further comprising: a first heat shrink film fitted on the first tube and the second tube, wherein a heat shrink mesh is laminated on the first heat shrink film, and a second heat shrink film is laminated on the heat shrink mesh, wherein a plurality of equidistant tensile grooves are formed on the outer wall of the second heat shrink film, and tensile components are provided in the tensile grooves, and connecting components are installed on the tensile components.

[0006] The heat shrinkable mesh is made of heat shrinkable fibers woven in a diamond pattern.

[0007] The tensile component includes two tensile rings, and both ends of the two tensile rings have through holes.

[0008] The connecting assembly includes a threaded rod and nuts screwed to both ends of the threaded rod.

[0009] The inner wall of the tensile ring has two raised annular structures.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention provides a heat shrink sleeve with high tensile strength. A heat shrink mesh is connected between a first heat shrink film and a second heat shrink film, improving the tensile strength between them. A tensile-resistant component can be installed within a tensile groove to fix the second heat shrink film to the outer wall of the pipe. When the first and second heat shrink films are subjected to tensile force, the tensile-resistant component, embedded in the tensile groove and tightly bonded to the second heat shrink film, disperses the tensile force, resulting in high overall tensile strength for the heat shrink sleeve. This prevents the heat shrink sleeve from loosening or breaking under tension when the pipe vibrates. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-9 The present invention provides a heat shrink sleeve with high tensile strength, comprising: a first tube 1 and a second tube 2, and further comprising: a first heat shrink film 3 sleeved on the first tube 1 and the second tube 2, wherein a heat shrink mesh 4 is laminated on the first heat shrink film 3, and a second heat shrink film 5 is laminated on the heat shrink mesh 4, wherein a plurality of equidistant tensile grooves 6 are opened on the outer wall of the second heat shrink film 5, and tensile components 7 are provided in the tensile grooves 6, and connecting components 8 are installed on the tensile components 7.

[0024] It should be noted that the first heat-shrinkable film 3, the heat-shrinkable mesh 4, and the second heat-shrinkable film 5 can be heat-shrinkably wrapped around the connection between the first pipe 1 and the second pipe 2, providing a seal. The double-layer wrapping of the first heat-shrinkable film 3 and the second heat-shrinkable film 5 improves the sealing effect. The heat-shrinkable mesh 4, connected between the first heat-shrinkable film 3 and the second heat-shrinkable film 5, enhances the tensile strength between them. The tensile-resistant component 7, installed in the tensile groove 6, can fix the second heat-shrinkable film 5 to the outer wall of the pipe. When the first heat-shrinkable film 3 and the second heat-shrinkable film 5 are subjected to tensile force, the tensile-resistant component 7, embedded in the tensile groove 6 and tightly combined with the second heat-shrinkable film 5, disperses the tensile force, further enhancing the overall tensile performance of the second heat-shrinkable film 5. This results in the heat-shrinkable sleeve having high tensile strength, preventing the connection of the heat-shrinkable sleeve from loosening or breaking under tension when the pipe shakes.

[0025] In a preferred embodiment, the heat-shrinkable mesh 4 is made of heat-shrinkable fibers woven in a diamond pattern.

[0026] It should be noted here that diamond mesh has better tensile strength.

[0027] In a preferred embodiment, the tensile component 7 includes two tensile rings 701, and both ends of the two tensile rings 701 have through holes 702.

[0028] It should be noted that the two tensile rings 701 can be combined and inserted into the tensile groove 6, and the two tensile rings 701 can be connected and fixed together by the connecting component 8.

[0029] In a preferred embodiment, the connecting assembly 8 includes a threaded rod 801 and nuts 802 screwed to both ends of the threaded rod 801.

[0030] It should be noted here that the threaded rod 801 can pass through the through holes 702 of the two tensile rings 701, and nuts 802 are screwed onto both ends of the threaded rod 801, thereby connecting and fixing the two tensile rings 701 together.

[0031] In a preferred embodiment, the inner wall of the tensile ring 701 is provided with two raised annular structures.

[0032] It should be noted here that the tensile ring 701 is conveniently embedded deep into the second heat-shrinkable film 5.

[0033] Working principle: The first heat-shrinkable film 3, the heat-shrinkable mesh 4, and the second heat-shrinkable film 5 are heat-shrinkably wrapped around the connection between the first tube 1 and the second tube 2, providing a seal. The double-layer wrapping with the first heat-shrinkable film 3 and the second heat-shrinkable film 5 improves the sealing effect. The heat-shrinkable mesh 4, connected between the first heat-shrinkable film 3 and the second heat-shrinkable film 5, enhances the tensile strength between them. The two tensile rings 701 can be joined together and inserted into the tensile groove 6. The threaded rod 801 can pass through the two tensile rings 701. A through hole 702 is made, and nuts 802 are screwed onto both ends of the threaded rod 801 to connect and fix the two tensile rings 701 together. This allows the second heat shrink film 5 to be fixed to the outer wall of the pipe. When the first heat shrink film 3 and the second heat shrink film 5 are subjected to tensile force, the tensile rings 701 are embedded in the tensile groove 6 and tightly combined with the second heat shrink film 5, thereby dispersing the tensile force and further enhancing the overall tensile performance of the second heat shrink film 5. This makes the heat shrink sleeve as a whole have high tensile strength, and prevents the heat shrink sleeve connection from becoming loose or breaking due to tension when the pipe shakes.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
