Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see Figure 1~3 , in an embodiment of the present invention, a pressure-stabilizing internal spiral plastic pipe for building drainage risers, including a pipe body 1, a main blade 2 and an auxiliary blade 3, the pipe body 1 is a cylindrical plastic drainage pipe, and the main The blade 2 and the auxiliary blade 3 are helical blades coaxially arranged on the inner wall of the pipe body 1 along the axial direction of the standpipe. The curvature of the ...

Abstract

The invention discloses a pressure-stabilizing type inner spiral plastic pipe for a building drainage vertical pipe. The pressure-stabilizing type inner spiral plastic pipe comprises a pipe body, a main blade and an auxiliary blade, wherein the pipe body is a cylindrical plastic drainage pipe, the main blade and the auxiliary blade are spiral blades coaxially arranged in the axial direction of thevertical pipe on the inner wall of the pipe body, and the joint between root parts of the main blade and the auxiliary blade and the inner wall of the pipe body is an arc excessive structure, and thecommensurate included angle between the main blade and the auxiliary blade is between 80 degrees and 130 degrees. According to the pressure-stabilizing type inner spiral plastic pipe for the buildingdrainage vertical pipe, 80% of water flow is borne by the main blade, and 20% of the water flow is borne by the auxiliary blade, so that good wall-attached spiral water flow is still formed during large drainage amount; and meanwhile, drainage flow within a certain pressure fluctuation range is improved due to reduction in pressure fluctuation, the water flow falling speed as well as noise are reduced, smell backflow in a bath room can be avoided, drainability is improved, loss influence on a floor drain water seal becomes very small, namely plus or minus 8 mm, and the drainage flow for a single vertical pipe can reach 13 liters per second.

Description

technical field [0001] The invention relates to the field of drainage pipes, in particular to a pressure-stabilizing inner spiral plastic pipe for building drainage risers. Background technique [0002] The building drainage riser is used for drainage in the vertical direction of the building. Through gravity, the water flow adheres to the inner wall of the pipe and falls, forming a film-like water flow falling along the inner wall of the pipe. In this state of water flow, the speed of the water flow decreases under the action of the frictional resistance of the pipe wall, forming a uniform flow. It is beneficial to improve the drainage performance of the pipeline, reduce the pressure fluctuation, prevent the floor drain of the bathroom from returning odor, and reduce the noise of the water flow. The plastic pipe is a kind of building drainage riser, but because the inner wall of the plastic pipe is smooth and the frictional resistance is small, when it is used in the buildi...
