Description

Noise reduction treatment layer for pipe Technical Field The utility model relates to the technical field of PVC pipes, in particular to a noise reduction treatment layer for a pipe. Background The pipe is a hollow section material made of metal, plastic or composite material, is used for manufacturing a pipeline system or other pipe fittings, has different performances such as strength, corrosion resistance, temperature resistance and the like, for example, a stainless steel pipe has strong corrosion resistance, a PVC pipe has light weight and low cost, the PVC pipe is a pipe made of polyvinyl chloride (Polyvinylchlorid, abbreviated as PVC), and the pipe is an indispensable basic material in building engineering, industrial facilities and daily life and is mainly used for conveying fluid (such as water, gas, petroleum and the like), protecting cables or serving as a structural support. The prior art scheme has the following defects that the existing PVC pipe lacks a noise reduction function, when the PVC pipe is used for supplying water, the sound of water flow in the pipe is transmitted, and noise is brought to the surrounding environment. Disclosure of utility model The utility model aims to provide a pipe noise reduction treatment layer. In order to achieve the above purpose, the present utility model provides the following technical solutions: The pipe noise reduction treatment layer comprises an inner pipe body, wherein a supporting piece is fixedly connected to the outer side of the inner pipe body, an outer pipe body is fixedly connected to the outer side of the supporting piece, a cavity is reserved between the inner pipe body and the outer pipe body, polyurethane foam is filled in the cavity, a foam layer is wrapped on the outer side of the outer pipe body, and a rubber layer is wrapped on the outer side of the foam layer. Through adopting above-mentioned technical scheme, adopt the mode of inside and outside pipe combination, form a brand-new body structure, it has polyurethane foam to fill between two pipe layers, can play inside effect of inhaling sound, also can not increase too much weight of tubular product simultaneously, guarantees the normal use of tubular product, and foam layer and the rubber layer in the outside increase the effect of giving sound insulation, and the polyurethane foam of cooperation inside plays fine noise reduction effect, also can protect the outside of tubular product simultaneously. Further, the outside of rubber layer has cup jointed first snap ring and second snap ring, the inside grafting of second snap ring has the lock bolt, lock nut has been cup jointed in the outside of lock bolt. Through adopting above-mentioned technical scheme, increase first snap ring and second snap ring, can fix between foam layer and rubber layer and the tubular product main part in the outside, easy to assemble and use. Further, the support piece is arranged between the inner pipe body and the outer pipe body, and four cavities are distributed in an equidistant annular mode. By adopting the technical scheme, a new pipe body structure is formed by the inner pipe and the outer pipe, and materials with sound absorption effect can be filled in the pipe body structure. Further, the first snap ring, the second snap ring, the locking bolt and the locking nut are respectively arranged at equal intervals, the first snap ring and the second snap ring are identical in size and consistent in specification, the locking bolt penetrates through the second snap ring and the first snap ring to extend to the outer side of the first snap ring, and the locking bolt is in threaded connection with the locking nut. By adopting the technical scheme, the fixing and the installation of the clamping ring are convenient. In summary, the beneficial technical effects of the utility model are as follows: The inner pipe body, the outer pipe body, the polyurethane foam, the foam layer and the rubber layer are adopted, the inner pipe body and the outer pipe body are increased, a cavity is formed between the two pipe bodies, the polyurethane foam can be filled in the cavity to achieve the effect of sound absorption, the foam layer and the rubber layer are increased on the outer side of the outer pipe body simultaneously, the sound insulation effect can be achieved, the good noise reduction effect can be achieved through cooperation with the polyurethane foam, and the noise reduction effect is achieved.
