[0029] The utility model will be further explained in combination with specific embodiments, however, people skilled in the art should understand that the detailed description given in combination with the drawings is for better explanation, the structure of the utility model must exceed these limited embodiments, and for some equivalent replacement schemes or common means, the detailed description will not be described in the text, but still belongs to the protection scope of the application.
[0030] A prefabricated sound attenuation water supply pipe material, comprising an inner pipe body 1 for water supply. An outer pipe body 2 is sleeved on the outside of the inner pipe body 1. The outer pipe body 2 and the inner pipe body 1 are concentrically arranged. An annular gap is arranged between the outer pipe body 2 and the inner pipe body 1. The annular gap between the inner pipe body 1 and the outer pipe body 2 can play a sound insulation role, reducing the noise of the water flow in the inner pipe body 1 from spreading outward.
[0031] The connecting arm 6 connects the inner pipe body 1 and the outer pipe body 2, and the connecting arm 6 is elastic. Part of the noise generated by the pipe material is caused by the relative vibration between the pipe structure and the wall in which it is embedded. The elastic connecting arm 6 can form a buffer structure between the inner pipe body 1 and the outer pipe body 2. When the water flow impacts the inner pipe body 1, causing the inner pipe body 1 to vibrate, the vibration of the inner pipe body 1 will not be transmitted to the outer pipe body 2, or less transmitted to the outer pipe body 2, thereby effectively reducing the noise generated by the relative vibration between the outer pipe body 2 and the wall.
[0032] In specific implementation, the connecting arm 6 is arc-shaped, and the connecting arm 6 has a certain included angle with respect to the radial direction of the inner pipe body 1. The connecting arms 6 are circumferentially distributed on the outer periphery of the inner pipe body 1.
[0033] When the water flow impacts the inner pipe body 1, causing the inner pipe body 1 to vibrate, the vibrating inner pipe body 1 can cause the connecting arm 6 to elastically deform, so that the connecting arm 6 can absorb and buffer the vibration. The vibration of the inner pipe body 1 will not be transmitted to the outer pipe body 2, or less transmitted to the outer pipe body 2, thereby effectively reducing the noise generated by the relative vibration between the outer pipe body 2 and the wall.
[0034] A spiral flow guide vane 3 is arranged in the inner pipe body 1. The spiral flow guide vane 3 divides the inner pipe body 1 into a plurality of flow channels.
[0035] In specific implementation, the spiral flow guide vane 3 is a spiral body with a cross-shaped cross section. The outer periphery of the spiral flow guide vane 3 is fixedly connected with the inner wall of the inner pipe body 1, and the center of the spiral flow guide vane 3 coincides with the center of the inner pipe body 1. The spiral flow guide vane 3 divides the inner pipe body 1 into four flow channels.
[0036] The spiral flow guide vane 3 can guide the water flow, so that the water flow in the inner pipe body 1 forms a spiral flow, changes the water flow from turbulent flow to steady flow, thereby reducing the turbulence in the pipe body, reducing the impact of the water flow on the pipe wall, and effectively reducing the noise. Moreover, the formation of steady flow can also improve the discharge capacity of the pipe body.
[0037] One end of the inner tube body 1 is provided with a positioning strip 4, and the other end of the inner tube body 1 is provided with a positioning groove 5 matched with the positioning strip 4. When multiple pipes need to be connected, the adjacent spiral flow guides 3 can be spliced with each other to form a continuous spiral structure.
[0038] The positioning strip 4 and the positioning groove 5 can form a positioning connection between adjacent pipes, the adjacent spiral flow guides 3 can be spliced with each other to form a continuous spiral structure, and water flow can flow on the continuous spiral structure. The water flow flows more smoothly between the pipes, especially at the connection of the pipes, and further prevents the generation of noise at the connection of the pipes.
[0039] In actual production, the inner tube body 1, the outer tube body 2, the connecting arm 6 and the spiral flow guide 3 can be integrally formed by a mold. The manufacturing process is simple, and the manufacturing cost is low.
[0040] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of claims.
