Description

Technical Field

[0001] This utility model relates to the field of plastic water pipe technology, specifically to a plastic water pipe with noise reduction function. Background Technology

[0002] Water pipes are pipes that supply water. In modern renovations, water pipes are usually installed by embedding them in walls. There are three types of water pipes: the first type is metal pipes, such as hot-dip galvanized cast iron pipes with internal plastic lining, copper pipes, and stainless steel pipes; the second type is plastic-coated metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes; and the third type is plastic pipes, such as PB pipes and PP-R pipes. Plastic pipes are widely used in daily life.

[0003] For example, Chinese patent CN213712139U discloses a plastic water pipe with noise reduction function, including a water pipe with a noise reduction layer on the outside and multiple hollow chambers evenly arranged inside the noise reduction layer. Six sets of flow guide strips are evenly arranged on the inside of the water pipe. This utility model device absorbs water flow noise through the noise reduction holes in the flow guide strips. Simultaneously, the multiple hollow chambers in the noise reduction layer further absorb noise. The noise reduction layer is made of damping material, further enhancing the noise reduction effect of the device. The flow guide strips increase the strength of the device, making it less prone to deformation and further improving its practicality. A protective layer on the outside of the noise reduction layer protects the device, improving its wear resistance and thus its service life.

[0004] Although the aforementioned patent can further absorb noise by using multiple hollow chambers within the sound-absorbing layer, and further enhance the sound absorption effect by using a damping material for the sound-absorbing layer, the material used to make the protective layer in the patent is not disclosed, resulting in mediocre corrosion resistance and heat insulation performance, thus reducing its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic water pipe with sound-absorbing function, which has advantages such as improved corrosion resistance. It solves the problem that the material used to make the protective layer is not publicly disclosed, resulting in mediocre corrosion resistance and poor heat insulation performance, thus reducing its practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic water pipe with a sound-absorbing function, comprising a water pipe body, an anti-corrosion mechanism on the outside of the water pipe body, and a sound insulation mechanism inside the water pipe body; the anti-corrosion mechanism includes a reinforcing layer disposed on the outside of the water pipe body, a heat insulation layer disposed on the outside of the reinforcing layer, a connecting layer disposed on the outside of the heat insulation layer, and an anti-corrosion layer disposed on the outside of the connecting layer.

[0007] Furthermore, the reinforcing layer is a glass fiber layer, and the heat insulation layer is a glass wool layer.

[0008] Furthermore, the connecting layer is a rigid polyurethane foam layer.

[0009] Furthermore, the anti-corrosion layer is a polyethylene layer.

[0010] Furthermore, the sound insulation mechanism includes a sound insulation layer disposed on the inner peripheral wall of the water pipe body, the sound insulation layer having at least two hollow chambers inside, and a sound-silencing layer disposed on the inner peripheral wall of the sound insulation layer.

[0011] Furthermore, the sound-silencing layer is a high-density polyethylene layer.

[0012] Furthermore, the sound insulation layer is a polyester fiber sound insulation cotton layer.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This sound-absorbing plastic water pipe, through the combined effect of the reinforcing layer, heat insulation layer, connecting layer, and anti-corrosion layer, can improve the thermal insulation performance, sound absorption performance, structural strength, and corrosion resistance of the plastic water pipe. The plastic water pipe can be widely used in many fields such as chemical industry, construction, and agriculture.

[0015] 2. This plastic water pipe with sound-absorbing function can effectively achieve sound absorption and sound insulation by setting a sound insulation layer on the inner circumferential wall of the water pipe body, thereby improving the sound-absorbing performance of the water pipe body. By setting a sound-silencing layer on the inner circumferential wall of the sound insulation layer, the inside of the sound-silencing layer is smooth and will not generate noise. At the same time, it has good flexibility and corrosion resistance, which enables the plastic water pipe to have a sound-absorbing function. Attached Figure Description

The outer side of the water pipe body 1 is provided with an anti-corrosion mechanism 2, which improves the anti-corrosion performance. The inner side of the water pipe body 1 is provided with a sound insulation mechanism 3, which can absorb and insulate sound, so that the plastic water pipe has a sound-absorbing function.

[0022] Please see Figure 2 In order to improve corrosion resistance, the corrosion protection mechanism 2 in this embodiment includes a reinforcing layer 201 disposed on the outside of the water pipe body 1, a heat insulation layer 202 disposed on the outside of the reinforcing layer 201, a connecting layer 203 disposed on the outside of the heat insulation layer 202, and an anti-corrosion layer 204 disposed on the outside of the connecting layer 203.

[0023] In this embodiment, the reinforcing layer 201 is a glass fiber layer, the heat insulation layer 202 is a glass wool layer, the connecting layer 203 is a rigid polyurethane foam layer, and the corrosion-resistant layer 204 is a polyethylene layer.

[0024] In this embodiment, the heat insulation performance, sound absorption performance, structural strength and corrosion resistance of the plastic water pipe can be improved through the synergistic effect of the reinforcing layer 201, the heat insulation layer 202, the connecting layer 203 and the anti-corrosion layer 204. The plastic water pipe can be widely used in many fields such as chemical industry, construction, and agriculture.

[0025] It should be noted that by setting a reinforcing layer 201 on the outside of the water pipe body 1, the structural strength of the water pipe body 1 can be improved, making it less prone to damage. By setting a heat insulation layer 202 on the outside of the reinforcing layer 201, the heat insulation layer 202 has good thermal insulation and sound absorption properties, and is also non-combustible and corrosion-resistant. By setting a connecting layer 203 on the outside of the heat insulation layer 202, the heat insulation performance of the water pipe body 1 can be further improved. By setting an anti-corrosion layer 204 on the outside of the connecting layer 203, the corrosion resistance of the outside of the water pipe body 1 can be improved, making the water pipe body 1 less prone to corrosion and extending its service life.

[0026] Please see Figure 3In order to absorb and insulate sound and enable the plastic water pipe to have a sound-absorbing function, the sound insulation mechanism 3 in this embodiment includes a sound insulation layer 301 disposed on the inner peripheral wall of the water pipe body 1. The sound insulation layer 301 has at least two hollow chambers 302 inside, and a sound-silencing layer 303 is disposed on the inner peripheral wall of the sound insulation layer 301.

[0027] In this embodiment, the sound-absorbing layer 303 is a high-density polyethylene layer, and the sound-insulating layer 301 is a polyester fiber sound-insulating cotton layer.

[0028] It should be noted that by setting a sound insulation layer 301 on the inner circumferential wall of the water pipe body 1, and then setting no fewer than a number of hollow chambers 302 inside the sound insulation layer 301, the sound absorption and sound insulation functions can be effectively achieved, and the sound absorption performance of the water pipe body 1 can be improved. By setting a sound-silencing layer 303 on the inner circumferential wall of the sound insulation layer 301, the sound-silencing layer 303 is smooth inside and will not generate noise, while having good flexibility and corrosion resistance.

[0029] The working principle of the above embodiments is as follows:

[0030] (1) By setting a reinforcing layer 201 on the outside of the water pipe body 1, the strength of the water pipe body 1 structure can be improved, and it is not easy to break. By setting a heat insulation layer 202 on the outside of the reinforcing layer 201, the heat insulation layer 202 has good heat insulation and sound absorption performance, and also has the characteristics of non-combustibility and corrosion resistance. By setting a connecting layer 203 on the outside of the heat insulation layer 202, the heat insulation performance of the water pipe body 1 can be improved again. By setting an anti-corrosion layer 204 on the outside of the connecting layer 203, the corrosion resistance of the outside of the water pipe body 1 can be improved, making the water pipe body 1 less prone to corrosion and extending its service life.

[0031] (2) By setting a sound insulation layer 301 on the inner peripheral wall of the water pipe body 1, and then setting a number of hollow chambers 302 inside the sound insulation layer 301, the sound absorption and sound insulation functions can be effectively realized, and the sound absorption performance of the water pipe body 1 can be improved. By setting a sound-silencing layer 303 on the inner peripheral wall of the sound insulation layer 301, the sound-silencing layer 303 is smooth inside and will not generate noise, while having good flexibility and corrosion resistance.
