Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water supply pipes, and particularly relates to a PE water supply pipe with earthquake resistance and sound insulation. Background Art
[0002] For PE water supply pipes, certain noise will be generated during use, which affects the lives of nearby residents. Most of the current sound insulation measures for pipe fittings are to wrap a sound insulation layer on the outer surface of the pipe fittings. However, due to the long length of the pipe fittings and the limitations of the installation environment, it is not conducive to the setting and assembly of the sound insulation layer. If the sound insulation layer is set on the inner wall of the pipe fitting, it is convenient for production and assembly. However, since the water supply pipe needs to ensure the water quality safety of the supplied water, designing the sound insulation layer inside the pipe fitting will affect the water quality safety.
[0003] Therefore, designing a water supply pipe that does not affect water quality safety and has good sound insulation effect is a problem that needs to be solved by the staff in this field. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a PE water supply pipe with earthquake resistance and sound insulation. Through the design of the inner lining body provided with sound-absorbing cotton, a sound-absorbing layer can be formed inside the pipe body, enabling the inner wall of the water supply pipe to be soft, which can reduce the noise caused by vibration. At the same time, the sound-absorbing layer can further reduce the noise transmission, and can greatly improve the sound insulation and noise reduction ability of the pipe fitting.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a PE water supply pipe with earthquake resistance and sound insulation, including a pipe fitting body and an inner lining body;
[0007] The inner lining body includes a sound-absorbing inner lining. Both ends of the outer surface of the sound-absorbing inner lining are fixedly provided with welding end pipes. A plurality of support ring bodies are linearly fixed on the outer surface of the sound-absorbing inner lining. A plurality of support ribs are evenly arranged at intervals in a ring shape on the outer surface of the support ring bodies;
[0008] The inner lining body is arranged inside the pipe fitting body, and the support ribs on the support ring bodies are in contact with the inner wall of the pipe fitting body;
[0009] Both ends of the outer surfaces of the two welding end pipes are fixedly welded with connecting end pipes, and the two connecting end pipes are respectively fixedly welded at both ends inside the pipe fitting body;
[0010] The sound-absorbing inner lining includes a sound insulation cotton layer, and an inner lining pipe is compounded on the inner surface of the sound insulation cotton layer.
[0011] Furthermore, a plurality of the support ring bodies are linearly arranged at the positions between the two welding end pipes, and the distances between any two of the plurality of support ring bodies and the two welding end pipes are the same.
[0012] Furthermore, an aluminum foil layer is laminated on the outer surface of the sound insulation cotton layer, and the support ring body and the welded end pipe are both fixed on the outer surface of the aluminum foil layer.
[0013] Furthermore, the inner liner pipe is an anti-corrosion inner liner layer, and an antibacterial coating is provided on the inner surface of the inner liner pipe.
[0014] Furthermore, the outer end face of the welded end pipe is flush with the end face of the pipe fitting body, and the outer end face of the connecting end pipe is flush with the end face of the pipe fitting body.
[0015] Furthermore, both the welded end pipe and the support ring body are rigid pipe fittings.
[0016] The utility model has the following beneficial effects:
[0017] 1. Through the design of the inner liner body provided with sound-absorbing cotton, the utility model can form a sound-absorbing layer inside the pipe body, making the inner wall of the water supply pipe soft, reducing the noise caused by vibration, and at the same time, the sound-absorbing layer can further reduce the noise transmission, greatly improving the sound insulation and noise reduction ability of the pipe fitting.
[0018] 2. By arranging the support ring body and the support ribs on the outer surface of the inner liner body, during the assembly process, the support ring body contacts the inner wall of the pipe fitting body through the support ribs, which can reduce the contact area between the inner liner body and the inner wall of the pipe fitting body during assembly, thereby reducing the friction force, facilitating the assembly, and at the same time reducing the damage of the inner liner during the assembly process.
[0019] 3. By designing the corrosion-resistant inner liner pipe, the utility model can greatly improve the corrosion resistance of the pipe fitting. At the same time, the designed antibacterial coating improves the antibacterial ability of the pipe fitting and enhances the safety during the use of the water supply pipe.
[0020] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
