Description

Hollow wall internal rotation pipe structure

Technical Field

The utility model relates to a building drainage riser field especially relates to a hollow wall internal rotation tubular construction.

Background

In China nowadays, a roof drain pipe or a toilet drain pipe of a building generally adopts a single-layer PVC drain pipe, the noise-proof performance of the drain pipe is weak, the price of the existing noise-proof drain pipe is high, which is several times that of the traditional drain pipe, and the manufacturing process of the existing noise-proof drain pipe is complex.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, provide a hollow wall internal coil structure, this hollow wall internal coil structure can effectually prevent that the drain pipe drainage from producing the noise, and the hollow wall chamber can effectual reduction water pipe produce the noise, and can realize the integration production to the cost of this hollow wall internal coil is low, can extensive use.

In order to achieve the above object, the utility model adopts the following technical scheme: a hollow wall internal rotation tube structure: comprises a pipe inner wall, a spiral double rib, a hollow wall cavity and a pipe outer wall; the inner wall of the pipe is the inner wall of a PVC drainage pipe; the spiral double-rib structure is a circular raised thread structure with two phases arranged on the inner wall of the PVC drainage pipe, and three spiral double-rib structures are arranged on the inner wall of the pipe, so that small water flow can slowly flow downwards along the inner wall of the pipe, large water flow falls spirally, and noise is reduced; the outer wall of the pipe is a PVC drain pipe on the outer layer of the inner wall of the pipe; the hollow wall cavity is a sheet-shaped connecting structure made of PVC materials and arranged on the outer side surface of the inner wall of the pipe, and four sheet-shaped connecting structures are arranged in the hollow wall cavity.

Preferably, the height of the circular bulge of the spiral double rib is 2mm-2.5mm, and the width of the circular bulge thread structure of one two-phase is 5mm-7 mm.

Preferably, the inner wall of the tube has a diameter of 100mm to 130 mm.

Preferably, the spiral double ribs are arranged in a way that the right-hand thread lead angle is designed to be 65-75 degrees.

Preferably, the inner wall of the pipe, the spiral double ribs, the hollow wall cavity and the outer wall of the pipe are integrally manufactured into a structure.

The utility model has the advantages that: this empty wall inner coil structure can effectually prevent that drain pipe drainage from producing the noise, and empty wall chamber can effectual reduction water pipe production noise, and can realize the integration production to this empty wall inner coil's cost is low, can extensive use.
