It is sliding, do not include the connector of inside and outside silk.It is generally used in embedded wall or deep-well built-in pipe.PPR pipe is moderate, performance is steady
Fixed, heat insulation is corrosion-resistant, and inner wall smooth non-scaling, pipe-line system are safe and reliable, and impermeable, and service life was up to 50 years.
In the prior art, in the technology of patent No. CN201621193109.2, PPR pipe has corrosion resistance, heat insulating ability
And the performance of buffering, but it is short of the function of corresponding noise reduction, and noise has subtle influence to life, and it is managed
Material is complicated, processes and its cumbersome, directly results in the increase of cost.
Utility model content
The purpose of this utility model is that propose a kind of bradyseism noise reduction PPR composite pipes, to propose a kind of economy, noise reduction
PPR pipe.
In order to achieve the above objectives, the utility model proposes a kind of bradyseism noise reduction PPR composite pipes, including Inner tubing layers, modeling
Shape aluminium layer and pipeline outer-layer；Wherein, the pipeline lining is wrapped with the moulding aluminium layer, and the moulding aluminium layer outer wrapping is
State pipeline outer-layer；
The pipeline lining includes a puigging and waterproof layer；The puigging includes convex block and noise reduction sliver；It is described convex
Block is evenly arranged in the outer layer of the waterproof layer, and is arranged with spiral shape in the waterproof layer outer layer；The top of the convex block
Equipped with froth bed；The noise reduction sliver is filled between the convex block and the moulding aluminium layer, to form the noise reduction of a plurality of spiral
Item layer；It is hollow noise reduction layer between the adjacent noise reduction item layer.
Preferably, the Inner tubing layers further include PTEE layers；Described PTEE layers is wrapped with the waterproof layer.
Preferably, the pipeline outer-layer includes insulating layer and zinc oxide film；The insulating layer is wrapped in the moulding aluminium layer
Outside；The zinc oxide film is wrapped in outside the insulating layer.
Preferably, it is mutually adhered to by hot melt adhesive between material layer and material layer.
Preferably, the inner ring of the bradyseism noise reduction PPR composite pipes is equipped with internal thread；The bradyseism noise reduction PPR multiple tubes
The outer ring of material is equipped with external screw thread.
Compared with prior art, the utility model is advantageous in that：The puigging includes convex block and noise reduction sliver,
Convex block is uniformly arranged in waterproof layer outer layer with spiral shape, and convex block cooperatively forms the noise reduction item layer of spiral with noise reduction sliver, right
Flow sound is passed to certain noise reduction, in the case where ensureing that raised stress degree is enough, adjacent noise reduction item layer
Between be equipped with hollow noise reduction layer, the transmission of sound is achieved the effect that adequately to obstruct while cost-effective, and convex
Froth bed on plaing a part of can fully play buffering with noise reduction sliver, prevent the explosion of tubing.
