Description

Technical Field

[0001] The present application relates to the technical field of pipeline components, and in particular to a pipeline insulation structure capable of resisting pipeline vibration. Background Art

[0002] A pipeline refers to a device connected by pipes, pipe fittings and valves for transporting gas, liquid or fluid with solid particles. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

[0003] The existing patent (publication number: CN209839467U) discloses a pipeline insulation structure that resists pipeline vibration, specifically involving the field of pipeline accessories, including an arc-shaped left side plate and an arc-shaped right side plate, the arc-shaped right side plate is arranged on the side of the arc-shaped left side plate, the inner sides of the arc-shaped left side plate and the arc-shaped right side plate are both bonded with a first insulation layer and the outer sides are fixed with a buffer mechanism group, the buffer mechanism group includes a plurality of buffer mechanisms, the buffer mechanism includes a buffer spring, one end of the buffer spring is fixed with an upper mounting block and the other end is fixed with a lower mounting block. The utility model can avoid the situation where the cold shrink hose causes friction with the installation environment due to vibration, thereby causing increased wear and affecting the service life, effectively extending the service life of the utility model, and at the same time, in conjunction with the setting of the cold shrink hose, the utility model only needs to be installed by sleeve-fitting the arc-shaped left side plate and the arc-shaped right side plate on the outside of the pipeline, and then sleeve-fitting the cold shrink hose, which is more convenient to install.

[0004] However, the above-mentioned pipeline insulation structure is provided with a buffer mechanism including a buffer spring, one end of which is fixedly provided with an upper mounting block and the other end of which is fixedly provided with a lower mounting block. In actual use, when the pipeline liquid flows, due to the lack of a damping structure, the spring is not sufficient to achieve the purpose of buffering and shock absorption, but makes the pipeline shake more violently. At the same time, during use, there is a large amount of space around the buffer mechanism group, which makes it easy for heat to be conducted, resulting in a significant reduction in the insulation performance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a pipeline insulation structure that is resistant to pipeline vibration and has the advantages of thermal insulation and earthquake resistance, and solves the problem that heat is easily conducted, resulting in greatly reduced thermal insulation performance and difficulty in earthquake resistance.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a pipeline insulation structure that resists pipeline vibration, comprising a first insulation layer arranged on the outer surface of the pipe, the first insulation layer and the second insulation layer are both made of polystyrene foam material, a plurality of evenly spaced buffer corrugated blocks are bonded to the outer surface of the first insulation layer, the plurality of buffer corrugated blocks are all made of polypropylene material, the two side surfaces of each of the buffer corrugated blocks are both bent, a second insulation layer is bonded to the outer surface of the plurality of buffer corrugated blocks, the outer surface of the second insulation layer is provided with two flame retardant layers, the two flame retardant layers are both made of asbestos material, the outer surfaces of the two flame retardant layers are provided with two protective covers, the two protective covers are symmetrically arranged, the interior of each buffer corrugated block and between every two adjacent buffer corrugated blocks are filled with buffer particles, the buffer particles are made of polystyrene material.

[0007] Through the above scheme, the first insulation layer and the second insulation layer are set to polystyrene foam material, which can prevent the liquid moisture transported inside the pipe from flowing outward. By setting the buffer corrugated block to polypropylene material, the buffer corrugated block can be compressed when the pipe vibrates to achieve the effect of energy absorption. At the same time, with the filled buffer particles, a certain damping effect can be produced to achieve the effect of buffering and shock resistance. The buffer particles are set to polystyrene material, which can improve the overall thermal insulation effect. By setting the flame retardant layer to asbestos material, it can not only play a flame retardant role against external fire, but also have a thermal insulation effect, thereby further improving the overall thermal insulation capacity.

[0008] Furthermore, the first thermal insulation layer is bonded to the pipe fitting.

[0009] Through the above solution, the first thermal insulation layer is bonded to the pipe fitting, which facilitates installation for users.

[0010] Furthermore, the first thermal insulation layer and the second thermal insulation layer are equal in length.

[0011] According to the above scheme, the first thermal insulation layer and the second thermal insulation layer are both formed of polystyrene foam, which not only has good water resistance but also has a certain buffering effect.

[0012] Furthermore, the plurality of buffer corrugated blocks are arranged in a circle.

[0013] Through the above scheme, the buffer corrugated block is set to polypropylene material, which has high impact resistance, strong mechanical properties, and can effectively play an impact-resistant role.

[0014] Furthermore, the buffer particles are spherical.

[0015] According to the above scheme, by setting the buffer particles to polystyrene material, the overall heat preservation and earthquake resistance effects can be improved.

[0016] Furthermore, the two flame retardant layers are bonded to the protective covers adjacent thereto.

[0018] Furthermore, the two flame retardant layers are arranged symmetrically.

[0019] According to the above scheme, the flame retardant layer is made of asbestos material, so as to achieve flame retardancy and improve overall thermal insulation.

[0020] Furthermore, the two protective covers are connected by bolts.

[0021] According to the above solution, the protective cover is connected with two bolts, which makes it convenient for users to assemble.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The pipeline insulation structure for resisting pipeline vibration can prevent moisture in liquid transported inside the pipe from flowing outward by setting the first insulation layer and the second insulation layer to be polystyrene foam materials, and can compress the buffer corrugated blocks to absorb energy when the pipe vibrates by setting the buffer corrugated blocks to be polypropylene materials, and can produce a certain damping effect with the filled buffer particles to achieve a buffering and shock-resistant effect, and the buffer particles are set to be polystyrene materials to improve the overall insulation effect, and the flame-retardant layer is set to be asbestos material, which can not only play a flame-retardant role against external fire, but also have a heat-insulating effect, and further improve the overall insulation capacity.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The first insulation layer 2 is bonded to the pipe fitting 1, which facilitates installation by users. The first insulation layer 2 and the second insulation layer 4 are equal in length. The first insulation layer 2 and the second insulation layer 4 are both made of polystyrene foam, which not only has good water resistance but also has a certain buffering effect. The first insulation layer 2 is bonded to the pipe fitting 1, and a plurality of evenly spaced buffer corrugated blocks 3 are bonded to the outer surface of the first insulation layer 2, and the plurality of buffer corrugated blocks 3 are all made of polypropylene material.

[0032] See also Figure 1 and Figure 4 The two sides of each buffer corrugated block 3 are multiple bent shapes, and the multiple buffer corrugated blocks 3 are arranged in a circle. The buffer corrugated blocks 3 are set to polypropylene material, which has high impact resistance and strong mechanical properties, and can effectively play an impact resistance role. The outer surfaces of the multiple buffer corrugated blocks 3 are bonded with a second thermal insulation layer 4, and the outer surface of the second thermal insulation layer 4 is provided with two flame retardant layers 5. The two flame retardant layers 5 are set to asbestos materials. The two flame retardant layers 5 are bonded to the protective cover 6 close to them. The two flame retardant layers 5 are bonded to the protective cover 6 close to them, which can facilitate the user to install and produce. The two flame retardant layers 5 are arranged symmetrically. The flame retardant layers 5 are set to asbestos materials, which can be flame retardant and improve the overall thermal insulation.

[0033] Among them, two protective covers 6 are provided on the outer surfaces of the two flame retardant layers 5, and the two protective covers 6 are connected by bolts. The protective covers 6 are set as two bolt connections, which can be convenient for users to assemble. The two protective covers 6 are arranged symmetrically, and the interior of each buffer corrugated block 3 and between every two adjacent buffer corrugated blocks 3 are filled with buffer particles 7. The buffer particles 7 are set to polystyrene material. The buffer particles 7 are set to spherical shape. By setting the buffer particles 7 to polystyrene material, the overall thermal insulation and seismic resistance effects can be improved.

[0034] In the present embodiment, a pipeline insulation structure that resists pipeline vibration can prevent moisture in the liquid transported inside the pipe 1 from flowing outward by setting the first insulation layer 2 and the second insulation layer 4 to be polystyrene foam materials. By setting the buffer corrugated block 3 to be polypropylene material, the buffer corrugated block 3 can be compressed when the pipe 1 vibrates to achieve the effect of energy absorption. At the same time, the filled buffer particles 7 can produce a certain damping effect to achieve the effect of buffering and shock resistance. The buffer particles 7 are set to polystyrene material to improve the overall insulation effect. The flame retardant layer 5 is set to asbestos material, which can not only play a flame retardant role against external fire, but also have a heat preservation effect, thereby further improving the overall insulation capacity.

[0035] It should be noted that the bolts fixing the two protective covers 6 are self-locking bolts to prevent the bolts from loosening after long-term use.

[0036] The working principle of the above embodiment is as follows: during production, the first insulation layer 2 is wrapped around the pipe 1 for bonding, and then the inside of the multiple buffer corrugated blocks 3 and between each two adjacent buffer corrugated blocks 3 are filled with buffer particles 7, and then two protective sleeves 6 are placed on the outer surface of the second insulation layer 4 and fixed by external bolts. When the water source flows and generates vibrations, the pipe 1 stretches and compresses the multiple buffer corrugated blocks 3, and can absorb energy through its own material properties and the corrugations on both sides. Since there are gaps between the filled buffer particles 7, it is possible to avoid interference with the stretching or compression of the buffer corrugated blocks 3. During the stretching and compression of the buffer corrugated blocks 3, the nearby buffer particles 7 can be squeezed to achieve a damping effect, thereby achieving a buffering and anti-seismic effect. At the same time, the filled buffer particles 7 and the first insulation layer 2 and the second insulation layer 4 can effectively insulate the pipe 1 and reduce heat conduction. The flame retardant layer 5 can be set to retard the external fire and protect the pipe 1, thereby buying time for extinguishing the fire, and at the same time further enhancing the overall insulation effect.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
