Description

Technical Field

[0001] This utility model relates to the field of PVC pipe technology, and in particular to a noise reduction treatment layer for pipes. Background Technology

[0002] Pipes are hollow cross-section materials made of metal, plastic or composite materials, used to make piping systems or other pipe fittings. Different pipe materials have different properties such as strength, corrosion resistance, and temperature resistance. For example, stainless steel pipes have strong corrosion resistance, while PVC pipes are lightweight and low in cost. PVC pipes are made of polyvinyl chloride (PVC). Pipes are an indispensable basic material in construction projects, industrial facilities and daily life. They are mainly used to transport fluids (such as water, gas, oil, etc.), protect cables or serve as structural supports.

[0003] The existing technical solutions mentioned above have the following drawbacks: existing PVC pipes lack noise reduction capabilities, and when PVC pipes are used for water supply, the sound of water flowing inside the pipes can be heard, causing noise to the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to provide a noise reduction treatment layer for pipes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The pipe noise reduction treatment layer includes an inner pipe body, a support member fixedly connected to the outside of the inner pipe body, an outer pipe body fixedly connected to the outside of the support member, a cavity reserved between the inner pipe body and the outer pipe body, the cavity being filled with polyurethane foam, a foam layer wrapped around the outside of the outer pipe body, and a rubber layer wrapped around the outside of the foam layer.

[0007] By adopting the above technical solution and using the combination of inner and outer tubes, a brand-new tube structure is formed. The space between the two tube layers is filled with polyurethane foam, which can achieve the effect of internal sound absorption without adding too much weight to the tube, ensuring the normal use of the tube. The outer foam layer and rubber layer increase the sound insulation effect, which, together with the inner polyurethane foam, achieves a good noise reduction effect and can also protect the outside of the tube.

[0008] Furthermore, a first retaining ring and a second retaining ring are sleeved on the outer side of the rubber layer, a locking bolt is inserted into the inside of the second retaining ring, and a locking nut is sleeved on the outer side of the locking bolt.

[0009] By adopting the above technical solution and adding a first retaining ring and a second retaining ring, the outer foam layer and rubber layer can be fixed to the pipe body, which facilitates installation and use.

[0010] Furthermore, the support is placed between the inner tube and the outer tube, and four cavities are evenly spaced in a ring.

[0011] By adopting the above technical solution, a new tube structure is formed by inner and outer tubes, and the inside can be filled with a material that has a sound-absorbing effect.

[0012] Furthermore, multiple first retaining rings, second retaining rings, locking bolts, and locking nuts are provided at equal intervals. The first retaining rings and second retaining rings are the same size and have the same specifications. The locking bolts pass through the second retaining rings and the first retaining rings and extend to the outside of the first retaining rings. The locking bolts and locking nuts are threaded together.

[0013] By adopting the above technical solution, the fixing and installation of the retaining ring can be facilitated.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] It adopts an inner tube body, an outer tube body, polyurethane foam, a foam layer and a rubber layer. The addition of an inner tube body and an outer tube body, with a cavity between the two tube bodies, allows for the filling of polyurethane foam inside the cavity, achieving a sound absorption effect. At the same time, the addition of a foam layer and a rubber layer on the outside of the outer tube body provides a sound insulation effect. Combined with the polyurethane foam, it can achieve a good noise reduction effect. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-3The pipe noise reduction layer includes an inner pipe body 1, a support member 2 fixedly connected to the outside of the inner pipe body 1, an outer pipe body 3 fixedly connected to the outside of the support member 2, a cavity 4 reserved between the inner pipe body 1 and the outer pipe body 3, the cavity 4 being filled with polyurethane foam 5, a foam layer 6 wrapped around the outside of the outer pipe body 3, a rubber layer 7 wrapped around the outside of the foam layer 6, a first retaining ring 8 and a second retaining ring 9 sleeved on the outside of the rubber layer 7, a locking bolt 10 inserted into the inside of the second retaining ring 9, and a locking nut 11 sleeved on the outside of the locking bolt 10. The combination of inner and outer pipes forms a new pipe structure. The polyurethane foam 5 filling between the two pipe layers can achieve an internal sound absorption effect without adding too much weight to the pipe, ensuring normal use of the pipe. The outer foam layer 6 and rubber layer 7 increase the sound insulation effect, working together with the inner polyurethane foam 5 to achieve a good noise reduction effect, while also protecting the outside of the pipe.

[0022] like Figure 1-3 As shown, the support member 2 is placed between the inner tube 1 and the outer tube 3. The cavity 4 has four equally spaced rings. The first retaining ring 8, the second retaining ring 9, the locking bolt 10 and the locking nut 11 are respectively arranged at equal intervals. The first retaining ring 8 and the second retaining ring 9 are the same size and have the same specifications. The locking bolt 10 passes through the second retaining ring 9 and the first retaining ring 8 and extends to the outside of the first retaining ring 8. The locking bolt 10 and the locking nut 11 are threaded together.

[0023] The implementation principle of this embodiment is as follows: The pipe itself has an inner pipe body 1 and an outer pipe body 3. Polyurethane foam 5 is filled between the inner pipe body 1 and the outer pipe body 3, which can play a sound absorption role. At the same time, a foam layer 6 and a rubber layer 7 are added to the outside of the outer pipe body 3 to play a sound insulation role. The two are used together to play a noise reduction role. Meanwhile, a retaining ring is added to the outside of the rubber layer 7. The foam layer 6 and the rubber layer 7 are fixed to the pipe body by the engagement of two sets of retaining rings and the cooperation between the locking bolt 10 and the locking nut 11.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
