Description

Technical Field

[0001] The utility model belongs to the technical field of PE pipes, and particularly relates to a sound-insulating PE pipe. Background Art

[0002] PE pipes play many key roles. In urban construction, they are an important part of the water supply and drainage system, ensuring the stable transportation and distribution of water resources. In industry, they facilitate the transmission of various fluids. With their durability, corrosion resistance and good physical properties, PE pipes silently support the operation of infrastructure in many industries and contribute to people's lives and economic development. However, some PE pipes on the market currently have some obvious shortcomings in terms of sound insulation, which has brought a lot of troubles to practical applications. The poor sound insulation effect causes the sound in the pipe to easily spread outward when conveying fluids, causing greater noise pollution. This is in some places that require a high level of environmental quietness, such as hospitals and schools. , residential areas, etc., will seriously affect people's quality of life and work. In these places, people expect a quiet environment, but the sound insulation defects of PE pipes make it difficult to achieve. This poor sound insulation performance may also cause problems in some industrial applications. For example, in the factory's piping system, the noise generated by fluid flow may interfere with the normal operation of workers, affecting work efficiency and safe production. At the same time, it may also interfere with other surrounding equipment and instruments, affecting their normal operation and accuracy. In summary, the current status of PE pipes with poor sound insulation has shown obvious shortcomings in many aspects, and urgently needs to be improved and enhanced to better adapt to the needs of different scenarios. Therefore, it is urgent to develop a sound-insulating PE pipe. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a sound-insulating PE pipe material, comprising: a PE pipe body 1 and a pipe inner cavity 2, wherein the PE pipe body 1 is provided with a pipe inner cavity 2 in the middle, an inner pipe 17 is provided inside the PE pipe body 1, and a sound-absorbing layer 16 is connected to the outer side of the inner pipe 17;

[0022] The outer side of the sound absorbing layer 16 is connected to the sound insulation layer 15, the outer side of the sound insulation layer 15 is connected to the central tube 14, the outer side of the central tube 14 is installed with a supporting inner frame 12, the outer side of the supporting inner frame 12 is connected to the outer tube layer 11, and a vacuum layer 13 is arranged in the middle of the supporting inner frame 12;

[0023] The supporting inner frame 12 includes an outer supporting ring 121 , an inner supporting ring 122 and reinforcing ribs 124 . The inner side of the outer supporting ring 121 is connected to the inner supporting ring 122 via a plurality of connecting plates 123 .

[0024] There are a plurality of outer support rings 121 , inner support rings 122 and reinforcing ribs 124 , and the reinforcing ribs 124 , outer support rings 121 , center tube 14 and inner support rings 122 are all made of stainless steel.

[0025] Each outer support ring 121 is connected to another adjacent outer support ring 121 via a plurality of reinforcing ribs 124 , and each inner support ring 122 is also connected to another adjacent inner support ring 122 via a plurality of reinforcing ribs 124 .

[0026] Both left and right ends of the PE pipe body 1 are closed structures, and multiple groups of honeycomb holes are formed through the upper and lower surfaces of the sound insulation layer 15 and the sound absorption layer 16.

[0027] The sound insulation layer 15 is made of butyl rubber, and the sound absorption layer 16 is made of polyester fiber sound absorption cotton.

[0028] The inner cavity 2 of the pipeline is located inside the inner tube 17 . The inner tube 17 and the outer tube layer 11 are both made of PE (polyethylene) material. The vacuum layer 13 is in a vacuum state.

[0029] See also Figure 1 and Figure 2 , as the first embodiment of the utility model: in actual use, when the fluid flows in the inner cavity 2 of the pipe, the sound is first transmitted to the sound absorbing layer 16 through the inner tube 17. The sound absorbing layer 16 can absorb the sound generated by the fluid flow for the first time, and the sound after absorption is transmitted to the sound insulation layer 15. The sound insulation layer 15 can absorb the sound for the second time. Through the first absorption of the sound absorbing layer 16, the intensity and energy of the sound of the fluid flow can be effectively reduced, and the generation and propagation of noise can be preliminarily reduced, which plays a key first step in reducing the overall noise level. The second absorption of the sound insulation layer 15 further enhances the sound insulation and noise reduction effect, so that the sound after layer-by-layer filtering and attenuation is greatly weakened, which greatly improves the acoustic quality of the surrounding environment and protects people from noise troubles. In addition, multiple groups of honeycomb holes are opened through the upper and lower surfaces of the sound insulation layer 15 and the sound absorbing layer 16. The honeycomb holes increase the contact area between the sound insulation layer 15 and the sound absorbing layer 16 and the sound, so that the sound can enter and be processed more fully, further improving the sound absorption and sound insulation effects.

[0030] See also Figures 1 to 3 , as the second embodiment of the utility model: combined with the further elaboration of the first embodiment, the sound after the second absorption by the sound insulation layer 15 is transmitted to the vacuum layer 13 through the central tube 14. When the sound reaches the vacuum layer 13, the sound wave gradually attenuates. The vacuum layer 13 can form an effective sound insulation barrier, which can greatly reduce the penetration of sound. The vacuum layer 13 further absorbs the sound again, which further strengthens the overall sound insulation effect and can block most of the remaining sound, achieving an extremely excellent sound insulation effect. This progressive absorption method greatly improves the reliability and stability of sound insulation.

[0031] And because a supporting inner skeleton 12 is provided outside the vacuum layer 13, the vacuum layer 13 can be supported under the action of the outer support ring 121, the inner support ring 122, the connecting plate 123 and the reinforcing ribs 124 to prevent the PE pipe body 1 from deforming due to the vacuum state, thereby ensuring the integrity and stability of the PE pipe body 1 structure.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
