Description

Noise reduction stereoplasm PVC drain pipe

Technical Field

The utility model mainly relates to a drainage pipe technical field specifically is a noise reduction stereoplasm PVC drain pipe.

Background

The noise-reducing rigid PVC drain pipe is prepared by adopting polyvinyl chloride resin as a main raw material and extruding and processing the polyvinyl chloride resin and other additives, has the characteristics of excellent physical and chemical properties, chemical corrosion resistance, high impact strength, small fluid resistance, aging resistance, long service life and the like, and is widely applied to drainage systems of various buildings.

The drainage pipeline can generate great noise when draining water, and the noise generated when draining water from a high layer downwards seriously influences the rest of people and the peace of a room particularly when people have a rest at night. Therefore, there is a need for a drain pipe having a superior noise reduction effect.

SUMMERY OF THE UTILITY MODEL

For solving prior art's not enough, the utility model provides a noise reduction stereoplasm PVC drain pipe, its simple structure, low in manufacturing cost separate the better noise reduction effect of noise reduction through the cavity noise reduction hole of drainage screw thread guide rivers regular flow noise reduction and body.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a stereoplasm PVC drain pipe of making an uproar reduces, includes body, cavity noise reduction hole, drainage screw thread, evenly set up a plurality of cavity noise reduction holes in the body, set up a plurality of drainage screw threads on the body inner wall, the drainage screw thread is the even distribution of heliciform on the body inner wall, drainage screw thread cross-section is triangle-shaped.

The diameter of the outer wall of the pipe body is 1.3-1.9mm, the diameter of the inner wall of the pipe body is 1.0-1.5mm, and the thickness of the pipe body is 0.3-0.4mm.

The number of the hollow noise reduction holes is 16.

The height of the drainage thread screw ridge is 2.8-3.0mm, the thread pitch between every two drainage threads is 8mm, and the number of the drainage threads is 6.

Contrast prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, low in manufacturing cost separate the noise through the cavity noise reduction hole of drainage screw thread guide rivers regular flow noise reduction and body and realize better noise reduction effect.
