Description

Technical Field

[0001] This utility model relates to the field of corrugated copper tube technology, and more specifically, to a corrugated shock-absorbing and noise-reducing copper tube. Background Technology

[0002] Corrugated copper pipes, with their unique flexible structure, play an indispensable role in modern industrial piping systems, especially in refrigeration and air conditioning, heat exchange equipment, fluid transportation, and fields that require handling thermal expansion and contraction, mechanical vibration, or complex installation paths. Compared to traditional rigid straight pipes, their core advantage lies in their ability to effectively absorb and compensate for pipeline system stress and displacement caused by factors such as temperature changes, equipment operation, or foundation settlement through axial or radial elastic deformation. This significantly reduces the risk of pipe rupture and joint leakage caused by stress concentration, improving system reliability and service life. This excellent flexibility and vibration resistance make them an ideal choice for pipeline connections under complex working conditions. However, traditional corrugated copper pipes are noisy and prone to wear at the joints during use.

[0003] On the one hand, when fluid flows through the inside of the bellows, the periodic undulating structure formed by its crests and troughs can easily break the laminar flow state of the fluid and induce turbulence. This unstable fluid movement continuously impacts the pipe wall and generates noise. On the other hand, the periodic or random mechanical vibrations generated by external mechanical equipment during operation will inevitably be transmitted to the bellows through the connection structure, resulting in noise generation.

[0004] On the other hand, under dynamic loads, there is inevitably a small relative movement between the pipe body and the joints and seals. This fretting wear will continuously wear down the pipe wall material and the sealing interface. The pipe wall is prone to gradually thinning due to fatigue and wear, which may eventually lead to fatigue cracking or pipe bursting. Moreover, after the sealing performance of the pipe body declines, it is easy to cause media leakage, which not only causes energy or material loss, but may also bring safety risks and environmental pollution.

[0005] Therefore, traditional corrugated copper tubes need improvement in terms of noise control and interface wear. Utility Model Content

[0006] In view of the aforementioned problems, and in conjunction with the first aspect of this utility model, an embodiment of this utility model provides a corrugated shock-absorbing and noise-reducing copper pipe. The device includes: a corrugated copper pipe body, the corrugated copper pipe body including an interface end, a plug end and a corrugated section, two sets of clamps are provided between two sets of the corrugated copper pipe bodies, and a buffer pad is provided between the two sets of clamps.

[0007] The corrugated section has an interface end at one end and a plug end at the other end.

[0008] Multiple sets of first buffer rings are provided on the periphery of the interface end, a second buffer ring is provided inside the socket end, and multiple sets of guide vanes are provided inside the socket end.

[0009] According to a preferred embodiment, the corrugated section has a wavy cross-section;

[0010] Both the interface end and the plug end are fixedly connected to both ends of the corrugated section by welding.

[0011] According to a preferred embodiment, multiple sets of mounting grooves are formed on the periphery of the interface end, and multiple sets of first buffer rings are installed in the mounting grooves. The periphery of multiple sets of first buffer rings is in contact with the inner wall of the insertion end of another set of corrugated copper tube bodies.

[0012] According to a preferred embodiment, a connecting groove is provided on the inner wall of the socket end, and the second buffer ring is installed in the connecting groove. One end of the second buffer ring is attached to the interface end on another set of the corrugated copper tube bodies.

[0013] According to a preferred embodiment, multiple sets of the guide vanes are spaced apart and arranged in a circumferential distribution on the inner wall of the insertion end.

[0014] According to a preferred embodiment, the inner walls of both sets of clamps are provided with slots, and the buffer pad is fitted in the two sets of slots, with the inner surface of the buffer pad fitting against the interface end and the plug end.

[0015] According to a preferred embodiment, both sets of clamps are connected on both sides by bolts and nuts.

[0016] Based on the above aspects, the embodiments of this application achieve the following:

[0017] Firstly, when users use this copper pipe, external machinery is prone to periodic vibrations. Multiple sets of first buffer rings are set around the interface end to buffer some of the impacts caused by vibrations, reducing the collision between the outer wall of the interface end and the inner wall of the socket end. At the same time, a second buffer ring is set on the inner wall of the socket end to reduce the metal collision between the interface end and the socket end. When the two pipe bodies are connected, the first and second buffer rings simultaneously buffer the vibration at the connection between the interface end and the socket end, thus improving the vibration reduction effect of the copper pipe.

[0018] Secondly, the two sets of clamps at the connection point of the two sets of corrugated copper pipes make the connection between the two sets of corrugated copper pipes more stable. At the same time, the buffer pads installed between the two sets of clamps can effectively reduce the noise generated by the periodic vibration of external machinery transmitted to the two sets of clamps through the corrugated copper pipes. This reduces the collision noise between the two sets of clamps and the corrugated copper pipes. In addition, the buffer pads can effectively reduce the friction between the clamps and the corrugated copper pipes, reduce wear, and extend the service life of the corrugated copper pipes. The spigot end is equipped with multiple sets of spaced guide vanes. The guide vanes can guide the flow of the fluctuating liquid flowing through the corrugated section to become more stable, reduce the collision between the liquid and the inner wall of the corrugated copper pipe, and achieve the effect of reducing the noise generated during the use of the copper pipe.

Figure 1 This is a schematic diagram of the structure of a corrugated shock-absorbing and noise-reducing copper tube provided in an embodiment of this utility model. Figure 2 This is an exploded view of a corrugated shock-absorbing and noise-reducing copper tube provided in an embodiment of this utility model.

Figure 4 This is a cross-sectional view of a corrugated shock-absorbing and noise-reducing copper tube provided in an embodiment of this utility model. The following is a detailed description of this corrugated shock-absorbing and noise-reducing copper tube.

[0026] The specific usage and function of this embodiment are explained below:

[0027] A corrugated shock-absorbing and noise-reducing copper pipe has a core corrugated copper pipe body, which consists of an interface end 100, a socket end 101, and a corrugated section 102. At the connection between the two corrugated copper pipe bodies, there are two sets of clamps 103, and a buffer pad 104 is sandwiched between them. One end of the corrugated section 102 is the interface end 100, and the other end is the socket end 101. Multiple sets of first buffer rings 105 are arranged on the outer periphery of the interface end 100, while a second buffer ring 106 is provided inside the socket end 101. The first buffer rings 105 and the second buffer rings 106 work together to buffer the collision between the interface end 100 and the socket end 101, thereby reducing the noise generated by the collision. In addition, multiple sets of guide vanes 107 are provided inside the socket end 101. These guide vanes 107 can guide the flow of fluid, making the fluid flow more stable.

[0028] The corrugated section 102 has a wavy cross-section. This unique design brings significant advantages. The wavy cross-section can increase the contact area between the corrugated copper tube body and the fluid. During heat exchange, a larger contact area means more efficient heat transfer, thereby effectively improving heat exchange efficiency. The interface end 100 and the spigot end 101 are fixed to both ends of the corrugated section 102 by welding, ensuring the stability of the entire corrugated copper tube body structure and preventing loosening of the connection during fluid transmission.

[0029] Multiple mounting slots 108 are provided on the periphery of the interface end 100. The multiple mounting slots 108 provide mounting positions for the first buffer rings 105. The multiple first buffer rings 105 are all installed in the corresponding mounting slots 108. When the two sets of corrugated copper pipe bodies are connected, the periphery of the multiple sets of first buffer rings 105 will be tightly fitted with the inner wall of the socket end 101 of the other set of corrugated copper pipe bodies. When the pipe is vibrated, the first buffer rings 105 can buffer part of the impact caused by the vibration, effectively reducing the hard collision between the outer wall of the interface end 100 and the inner wall of the socket end 101, and reducing the noise and wear caused by the collision.

[0030] The inner wall of the socket end 101 is provided with a connecting groove 109, and the second buffer ring 106 is installed in this connecting groove 109. When the two sets of corrugated copper tube bodies are connected, one end of the second buffer ring 106 will fit against the interface end 100 on the other set of corrugated copper tube bodies. The second buffer ring 106 reduces the metal collision between the interface end 100 port and the socket end 101. While reducing collision noise, it also reduces wear caused by collision and extends the service life of the copper tube.

[0031] Multiple sets of guide vanes 107 are distributed in a circumferential pattern on the inner wall of the spigot end 101. When the fluid flows through the corrugated section 102 and enters the spigot end 101, the fluid may fluctuate due to the change in the pipe structure. At this time, the multiple sets of guide vanes 107 can guide the direction of these fluctuating liquid flows, making the flow more stable and reducing the collision between the liquid and the inner wall of the corrugated copper pipe body caused by irregular flow, thereby reducing the noise generated during the use of the copper pipe.

[0032] Both sets of clamps 103 have grooves 110 on their inner walls. Buffer pads 104 are fitted into the grooves 110. The inner surface of the buffer pads 104 fits tightly against the interface end 100 and the plug end 101. When external machinery generates periodic vibrations, the buffer pads 104 can effectively block the vibrations and reduce the noise generated by the vibrations transmitted through the corrugated copper pipe body to the two sets of clamps 103. At the same time, the buffer pads 104 can also effectively reduce the friction between the clamps 103 and the corrugated copper pipe body, reduce the wear of the components, and thus improve the overall service life of the corrugated copper pipe body.

[0033] Both sides of the two sets of clamps 103 are connected by bolts and nuts. By tightening the bolts and nuts, the two sets of corrugated copper pipe bodies can be connected together, ensuring that the connection part has sufficient stability.
