Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe manufacturing, in particular to a floating-point sound-absorbing PVC pipe. Background Art

[0002] Floating-point silencer PVC pipe is a piping system designed specifically to reduce water flow noise. It is widely used in building water supply and drainage systems. Its internal structure adopts a special floating-point design, which can effectively reduce the noise generated when water flows through the pipe and improve the comfort of the living environment. This technology is usually combined with the corrosion resistance and pressure resistance of PVC pipes to make the pipe more stable and durable during use.

[0003] However, in actual use, the following deficiencies still exist. For example, existing PVC pipes generate noise when water flows inside them. The noise generated by water impacting the PVC pipes is often unacceptable, especially in high-end apartments, hotels, and office buildings. It is incompatible with the overall environmental atmosphere created by the building, seriously affecting people's work and life experience. The noise generated by the water supply and drainage system has a negative impact on people's sleep and rest, and may even cause disputes. Long-term exposure to a noisy environment will have adverse effects on human health, such as hearing loss and increased psychological stress.

[0004] Therefore, the utility model proposes a floating point sound-absorbing PVC pipe to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a floating-point sound-absorbing PVC pipe.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a floating point silencer PVC pipe, comprising an inner pipe, a silencer float is fixedly connected to the inner pipe, a guide rib is fixedly connected to the side of the inner pipe close to the silencer float, a connecting plate is fixedly connected to the inner pipe, and an outer pipe is fixedly connected to the side of the connecting plate away from the inner pipe.

[0007] As a preferred embodiment, a partition is fixedly connected to the connecting plate.

[0008] The beneficial effect of adopting the above further solution is: since the partition is fixedly connected to the connecting plate, a foam layer and a hollow sound insulation layer can be set between the inner tube and the outer tube to further reduce the noise generated when the water flows in the inner tube.

[0009] As a preferred embodiment, a foam layer is provided between the outer tube and the partition.

[0010] The beneficial effect of adopting the above further solution is that: since a foaming layer is provided between the outer tube and the partition plate, a foaming material can be provided in the foaming layer, and the foaming material can isolate a part of the noise.

[0011] As a preferred embodiment, foam rubber is provided in the foam layer.

[0012] The beneficial effect of adopting the above further solution is that since the foamed rubber is provided in the foamed layer, the foamed rubber can be completely filled into the interior of the foamed layer, thereby preventing the interior of the foamed layer from being not fully filled and affecting the sound insulation effect.

[0013] As a preferred embodiment, the foamed rubber is foamed nitrile rubber.

[0014] The beneficial effects of adopting the above further scheme are: since the foamed rubber is foamed nitrile rubber, it can cut off most noise transmission paths and effectively reduce vibration noise. Since it is a foamed material, it is lighter than solid rubber of the same volume and has better sound insulation performance. Compared with other high-performance rubbers, foamed nitrile rubber usually has a relatively reasonable cost, making it an economical and practical choice in many industrial applications.

[0015] As a preferred embodiment, a hollow sound insulation layer is provided between the inner tube and the partition.

[0016] The beneficial effect of adopting the above further solution is: since a hollow sound insulation layer is provided between the inner tube and the partition, the hollow sound insulation layer can increase the damping of the pipe along the flow direction and enhance the sound insulation effect. This design does not change the plasticity of PVC, but can significantly improve the sound insulation performance.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] In the utility model, the main function of the silencer float is to reduce the noise generated when water flows in the inner pipe, which can effectively reduce the sound caused by the water impacting the pipe wall, making the living environment quieter. Through the set guide ribs, the silencer float can optimize the water flow path and improve the drainage efficiency. At the same time, due to its special structural design, it can also increase the strength and impact resistance of the pipe to a certain extent, thereby reducing the technical problem of noise generated when water flows in the inner pipe.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 2 As shown, this embodiment provides a technical solution: a floating point silencer PVC pipe, comprising an inner pipe 1, a silencer float 2 fixedly connected to the inner pipe 1, a guide rib 3 fixedly connected to the side of the inner pipe 1 close to the silencer float 2, a connecting plate 4 fixedly connected to the inner pipe 1, and an outer pipe 5 fixedly connected to the side of the connecting plate 4 away from the inner pipe 1. The main function of the silencer float 2 is to reduce the noise generated when the water flows in the inner pipe 1. It optimizes the water flow path by setting the guide rib 3, making the water flow smoother and reducing the noise generated by the water impacting the pipe wall. This design effectively improves the drainage efficiency rate, while reducing the noise level, making the living environment quieter. The special structural design of the silencer float 2 also increases the strength and impact resistance of the pipe. It adopts a multi-layer composite structure, the inner wall is provided with a guide rib 3, the outer wall is made of modified polyvinyl chloride material, and the middle layer is foamed nitrile rubber. This structure can not only effectively reduce noise, but also improve the durability and stability of the pipe. In addition, the silencer float 2 also has good weather resistance and chemical stability, and can maintain stable performance in various harsh environments, thereby reducing the technical problem of noise generated when water flows in the inner pipe 1.

[0027] The above solution still has the problem that after the inner tube 1 is silenced, it cannot further eliminate the noise. Figure 2-Figure 4As shown: a partition 6 is fixedly connected to the connecting plate 4. Since the partition 6 is fixedly connected to the connecting plate 4, a foam layer 7 and a hollow sound insulation layer 9 can be set between the inner tube 1 and the outer tube 5 to further reduce the noise generated when the water flows in the inner tube 1. A foam layer 7 is provided between the outer tube 5 and the partition 6. Since a foam layer 7 is provided between the outer tube 5 and the partition 6, a foam material can be provided in the foam layer 7. The foam material can isolate part of the noise. A foam rubber 8 is provided in the foam layer 7. Since the foam rubber 8 is provided in the foam layer 7, the foam rubber 8 can be completely filled into the interior of the foam layer 7 to prevent the interior of the foam layer 7 from being not filled solid and affecting the sound insulation effect. The rubber 8 is a foamed nitrile rubber. Since the foamed rubber 8 is a foamed nitrile rubber, it can cut off most of the noise transmission paths and effectively reduce vibration noise. Since it is a foamed material, it is lighter than solid rubber of the same volume and has better sound insulation performance. Compared with other high-performance rubbers, foamed nitrile rubber usually has a relatively reasonable cost, making it an economical and practical choice in many industrial applications. A hollow sound insulation layer 9 is provided between the inner tube 1 and the partition 6. Since a hollow sound insulation layer 9 is provided between the inner tube 1 and the partition 6, the hollow sound insulation layer 9 can increase the damping of the pipe along the flow direction and enhance the sound insulation effect. This design does not change the plasticity of PVC, but can significantly improve the sound insulation performance.

[0028] Working principle:

[0029] like Figure 1-Figure 4 As shown, the main function of the silencer float 2 is to reduce the noise generated when the water flows in the inner pipe 1, which can effectively reduce the sound caused by the water impacting the pipe wall, making the living environment quieter. Through the provided guide ribs 3, the silencer float 2 can optimize the water flow path and improve the drainage efficiency. At the same time, due to its special structural design, it can also increase the strength and impact resistance of the pipe to a certain extent. Since a foam layer 7 is provided between the outer pipe 5 and the partition 6, a foam material can be provided in the foam layer 7, and the foam material can isolate a part of the noise. Since a foam rubber 8 is provided in the foam layer 7, the foam rubber 8 can be completely filled into the interior of the foam layer 7, preventing The interior of the foaming layer 7 is not filled solid, which affects the sound insulation effect. Since the foaming rubber 8 is foamed nitrile rubber, it can cut off most of the noise transmission paths and effectively reduce vibration noise. Since it is a foam material, it is lighter than solid rubber of the same volume and has better sound insulation performance. Compared with other high-performance rubbers, foamed nitrile rubber usually has a relatively reasonable cost, making it an economical and practical choice in many industrial applications. Since a hollow sound insulation layer 9 is provided between the inner tube 1 and the partition 6, the hollow sound insulation layer 9 can increase the damping of the pipe along the flow direction and enhance the sound insulation effect. This design does not change the plasticity of PVC, but can significantly improve the sound insulation performance.

However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
