Abstract
The utility model discloses a hollow spiral noise reduction pipe. The noise reduction pipe is characterized by comprising a three-layer pipe body structure including an inner layer pipe, a middle layer pipe and an outer layer pipe. A connecting rib is disposed between the inner layer pipe and the middle layer pipe. Gaps between the connecting rib and the inner and the middle layer pipes are filled with filling materials. A steel wire reinforced mesh layer is pasted between the middle layer pipe and the outer layer pipe through bonding materials. The inwall of the inner layer pipe is coated by a sand blasting layer and provided with spiral convex ribs and spaced protrusions. The outer wall of the outer layer pipe is coated by an anti-corrosion layer. The anti-corrosion layer is coated by a separating layer. The noise reduction pipe is reasonable in design, and provided with the three-layer pipe body structure, the connecting ribs, the filling materials and the steel wire reinforced mesh layer, so as to increase the intensity of the pipe body. The separating layer and the sand blasting layer are used for reducing noise with good noise reduction effects. The anti-corrosion layer is used for improving anti-corrosion performance.
Description
Technical field
The utility model relates to pipeline field, relates in particular to a kind of hollow spiral hush pipe.
Background technique
Existing hollow spiral hush pipe is simple in structure, and the noise producing in its using process is large, and its body mostly adopts single layer structure, is easily subject to water pressure and is out of shape or damages after its long-term use, affects its working life.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of hollow spiral hush pipe is provided.
The utility model is achieved through the following technical solutions:
A kind of hollow spiral hush pipe, it is characterized in that: three layers of pipe structure that include inner tube, middle tube, external pipe formation, between described inner tube and middle tube, be provided with connecting tendon, and be filled with stuffing between connecting tendon and inner tube and middle tube, between described middle tube and external pipe, by adhesive material, be bonded with steel wire and strengthen stratum reticulare, the inwall of described inner tube is provided with sandblast layer, and on inwall, be also distributed with spiral convex rib and projection spaced apart, the outer wall of described external pipe is provided with anticorrosive coat, and described anticorrosive coat is provided with separation layer outward.
The utility model has the advantages that:
The utility model reasonable in design, by the structural design of three layers of pipeline, connecting tendon, stuffing and steel wire reinforcement stratum reticulare, has increased the intensity of body, by the structure of separation layer, sandblast layer, reduced noise, good muffling effect, by the structure of anticorrosive coat, increased antiseptic property.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
