Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically a compressor corrugated metal hose. Background Technology

[0002] Existing compressor corrugated metal hoses are flexible connecting pipes specifically designed for compressor systems. In the prior art, a utility model patent with authorization publication number CN 222746793 U discloses a compressor corrugated metal hose, including a corrugated pipe with a wear-resistant sleeve covering its surface. The wear-resistant sleeve has a mesh sleeve, and both ends of the corrugated pipe have clamps. While the wear-resistant sleeve, positioned between the mesh sleeve and the corrugated pipe, protects the corrugated pipe from vibration, preventing the mesh sleeve from cutting and damaging the corrugated pipe's crests and extending the service life of the compressor corrugated metal hose, this design effectively extends the service life of the compressor corrugated metal hose.

[0003] However, the wear-resistant sleeve structure set between the mesh sleeve and the bellows is usually a single-layer fabric structure. Although this fabric structure has a certain degree of wear resistance and can provide some protection for the bellows, its elasticity cannot be guaranteed, which has the disadvantage of affecting the bending deformation of the bellows. In addition, the compressor operates in a harsh environment, and is sometimes used in humid environments such as water rooms. This type of wear-resistant sleeve structure is prone to bacterial growth and corrosion, which greatly reduces its durability. Its effect on extending the service life of the compressor's bellows metal hose needs to be improved. Furthermore, during long-term use, when the bellows is partially damaged, the entire hose structure needs to be disassembled and replaced, which is not possible to replace a single bellows, resulting in a waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide a compressor corrugated metal hose. The wear-resistant sleeve can protect the corrugated hose without affecting its original bending deformation performance. It also has good antibacterial and anti-corrosion effects, which further enhances the effect of extending the service life of the compressor corrugated metal hose, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compressor corrugated metal hose, comprising: a corrugated pipe, both ends of which are fixedly connected to connecting pipes, the end of the connecting pipe away from the corrugated pipe being connected to a flange, a wear-resistant sleeve fitted on the outside of the corrugated pipe, a mesh sleeve fitted on the outside of the wear-resistant sleeve, and first pipe clamps fitted on both ends of the outer wall of the mesh sleeve, the wear-resistant sleeve being woven from spun yarn, and the connecting pipe being connected to the flange through a connecting assembly.

[0006] Preferably, the spun yarn includes: anti-abrasion yarn, antibacterial yarn, first elastic yarn and second elastic yarn. The abrasion-resistant sleeve is made of multiple anti-abrasion yarns woven in a plain weave. There are gaps between the multiple anti-abrasion yarns, and antibacterial yarns are interspersed in the multiple gaps. The outer side of the anti-abrasion yarn is twisted and connected to the first elastic yarn, and the outer side of the antibacterial yarn is twisted and connected to the second elastic yarn.

[0007] Preferably, heat shrink tubing is fitted on the outer side of both the first and second tubing clamps.

[0008] Preferably, the connecting assembly includes: a pair of threaded pipes, which are respectively threaded to the inner walls of two flanges; a collar is fixedly fitted on the outer wall of the threaded pipe; a sealing ring is fixedly fitted on the collar against the surface of the flange; the sealing ring abuts against the flange; a soft sleeve is fitted on the outer side between the connecting pipe and the threaded pipe; and a second pipe clamp is fitted on both sides of the outer wall of the soft sleeve.

[0009] Preferably, a magnetic absorbing plate is fixed to the end of the connecting pipe near the threaded pipe, and the magnetic absorbing plate is magnetically attracted to the threaded pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This compressor corrugated metal hose has the following advantages over traditional technology:

[0011] Through the cooperation of the corrugated pipe, flange, connecting pipe, braided sleeve, wear-resistant sleeve, and spinning thread, the wear-resistant sleeve set between the braided sleeve and the corrugated pipe can protect the corrugated pipe and prevent the braided sleeve from cutting the crest of the corrugated pipe due to the vibration of the corrugated pipe. In addition, the wear-resistant sleeve has excellent wear resistance and good elastic deformation ability, and will not affect the original bending deformation performance of the corrugated pipe. The antibacterial thread in the wear-resistant sleeve contains hemp fiber, which is rich in a variety of natural antibacterial trace elements, which can effectively inhibit the growth of bacteria, making it difficult for bacteria to grow inside the wear-resistant sleeve, reducing the chance of corrosion in humid environments, thereby further enhancing the effect of extending the service life of the compressor corrugated metal hose.

[0012] By utilizing the fit between the bellows, flanges, connecting pipes, braided sleeves, wear-resistant sleeves, spinning thread, and connecting components, when local damage occurs to the bellows during long-term use, maintenance personnel can loosen and disassemble the second pipe clamp, significantly reducing the clamping force between the soft sleeve and the connecting pipe. At this point, the bellows can be pulled out from inside the connecting pipe. Then, by loosening and disassembling the first pipe clamp, the bellows can be pulled out from inside the wear-resistant sleeve. This allows for the replacement of a single damaged bellows without replacing the flanges and other structures at both ends of the bellows. This not only saves resources but also eliminates the need for disassembling and installing the flanges, thus enhancing practicality. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a compressor corrugated metal hose, comprising: a corrugated pipe 1, with connecting pipes 2 fixedly connected to both ends of the corrugated pipe 1, a flange 3 connected to the end of the connecting pipe 2 away from the corrugated pipe 1, a wear-resistant sleeve 5 fitted on the outside of the corrugated pipe 1, a mesh sleeve 4 fitted on the outside of the wear-resistant sleeve 5, and a first pipe clamp 7 fitted on both ends of the outer wall of the mesh sleeve 4, the wear-resistant sleeve 5 being woven from spun yarn 6, and the connecting pipe 2 being connected to the flange 3 through a connecting assembly.

[0020] In the specific implementation process, it is worth noting that the connecting pipe 2 and the bellows 1 are integrally formed structures, the flange 3 is used to connect the bellows 1 to the corresponding installation position in the external compressor, and the inner wall of the first pipe clamp 7 abuts against the outer wall of the mesh sleeve 4.

[0021] Furthermore, the spinning thread 6 includes: anti-abrasion yarn 601, antibacterial yarn 602, first elastic yarn 603 and second elastic yarn 604. The abrasion-resistant sleeve 5 is made of multiple anti-abrasion yarns 601 in plain weave. There are gaps between the multiple anti-abrasion yarns 601, and antibacterial yarns 602 are interspersed in the gaps. The outer side of the anti-abrasion yarn 601 is twisted and connected to the first elastic yarn 603, and the outer side of the antibacterial yarn 602 is twisted and connected to the second elastic yarn 604.

[0022] In the specific implementation process, it is worth noting that the abrasion-resistant yarn 601 is a carbon fiber yarn, which has excellent high strength, high modulus and abrasion resistance. The first elastic yarn 603 and the second elastic yarn 604 are both spandex fiber yarns, which are known for their excellent elasticity. Twisting is achieved by twisting to make the fibers rotate relative to each other, forming a spiral structure to enhance the cohesion. Both carbon fiber and spandex yarns are long filament structures in physical form, and can be connected through the twisting process. Twisting connection can combine the advantages of both to form a composite yarn with both high strength and elasticity. The abrasion-resistant sleeve 5 spun from this composite yarn has excellent abrasion resistance and good elastic deformation ability. The antibacterial yarn 602 is a hemp fiber yarn, which contains hemp fiber. Hemp fiber is rich in a variety of natural antibacterial trace elements, which can effectively inhibit the growth of bacteria.

[0023] Furthermore, heat shrink tubing 14 is fitted onto the outer sides of both the first clamp 7 and the second clamp 12.

[0024] In the specific implementation process, it is worth noting that the heat shrink tubing 14 is a tubular product made of high molecular polymer material, which has the characteristic of shrinking after being heated. Its core principle is to utilize the "thermal memory effect" of the material, that is, the material is pre-stretched and shaped during processing, and when heated to a specific temperature, it will return to its original shrinkage state, thus tightly wrapping around the covered object. It can protect the two inner tube clamps and prevent dust and impurities from adhering to its threads, which facilitates smooth loosening and disassembly in the future.

[0025] Furthermore, the connecting assembly includes: a pair of threaded pipes 8, which are threadedly connected to the inner walls of the two flanges 3 respectively; a collar 9 is fixedly fitted on the outer wall of the threaded pipe 8; a sealing ring 10 is fixedly fitted on the collar 9 against the surface of the flange 3; the sealing ring 10 abuts against the flange 3; a soft sleeve 11 is fitted on the outer side between the connecting pipe 2 and the threaded pipe 8; and a second pipe clamp 12 is fitted on both sides of the outer wall of the soft sleeve 11.

[0026] In the specific implementation process, it is worth noting that the sealing ring 10 and the soft sleeve 11 are made of rubber and have a certain degree of flexibility. When the corrugated pipe 1 is partially damaged, the maintenance personnel can loosen and disassemble the second pipe clamp 12 to greatly reduce the clamping force between the soft sleeve 11 and the connecting pipe 2. At this time, the corrugated pipe 1 can be pulled out from the inside of the connecting pipe 2. Then, the first pipe clamp 7 can be loosened and disassembled to pull the corrugated pipe 1 out from the inside of the wear-resistant sleeve 5. The single damaged corrugated pipe 1 can be replaced without replacing the flanges 3 and other structures at both ends of the corrugated pipe 1.

[0027] Furthermore, a magnetic absorbing piece 13 is fixed to the end of the connecting pipe 2 near the threaded pipe 8, and the magnetic absorbing piece 13 is magnetically attracted to the threaded pipe 8.

[0028] In the specific implementation process, it is worth noting that the magnetic absorbing piece 13 is a magnetic ring piece and the threaded pipe 8 is a galvanized iron pipe, which can improve the stability of the connection between the connecting pipe 2 and the threaded pipe 8 to a certain extent.

[0029] Working principle:

[0030] Use of corrugated metal flexible hoses:

[0031] The user first connects the flanges 3 at both ends of the corrugated pipe 1 to the corresponding installation positions in the external compressor, and then the corrugated metal hose can be used normally. During use, the wear-resistant sleeve 5 set between the braided sleeve 4 and the corrugated pipe 1 can protect the corrugated pipe 1 and prevent the braided sleeve 4 from cutting the crest of the corrugated pipe 1 due to the vibration of the corrugated pipe 1. In addition, the wear-resistant sleeve 5 has excellent wear resistance and good elastic deformation ability, and will not affect the original bending deformation performance of the corrugated pipe. The antibacterial filaments 602 in the wear-resistant sleeve 5 contain hemp fiber. Hemp fiber is rich in a variety of natural antibacterial trace elements, which can effectively inhibit the growth of bacteria, making it difficult for bacteria to grow inside the wear-resistant sleeve 5, reducing the chance of corrosion in humid environments, thereby further enhancing the effect of extending the service life of the compressor corrugated metal hose.

[0032] Replacement of a single bellows:

[0033] During long-term use, when the corrugated pipe 1 is partially damaged, maintenance personnel can loosen and disassemble the second pipe clamp 12 to significantly reduce the clamping force between the soft sleeve 11 and the connecting pipe 2. At this time, the corrugated pipe 1 can be pulled out from the inside of the connecting pipe 2. Then, the first pipe clamp 7 can be loosened and disassembled to pull the corrugated pipe 1 out from the inside of the wear-resistant sleeve 5. The single damaged corrugated pipe 1 can be replaced without replacing the flanges 3 at both ends of the corrugated pipe 1. This not only saves resources but also eliminates the need to disassemble and install the flanges 3.

[0034] Bellows repositioning and installation:

[0035] First, put the wear-resistant sleeve 5 and the mesh sleeve 4 on the outside of the new corrugated pipe 1 in sequence, and tighten the mesh sleeve 4 with the first pipe clamp 7. Then, insert the connecting pipe 2 at both ends of the new corrugated pipe 1 into the soft sleeve 11 and the threaded pipe 8. Tighten the soft sleeve 11 with the second pipe clamp 12 to complete the overall replacement of the corrugated pipe 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
