Abstract
The utility model discloses a hollow hush pipe, which comprises a pipeline. Axial through holes are arranged in the wall of the pipeline, and protruding axial spiral lead ribs are arranged on the inner wall of the pipeline. The hollow hush pipe is capable of effectively reducing noises caused by water drainage. The axial through holes in the pipeline wall can reduce pressure in the pipe and pressure oscillation and can increase the application safety factor of the pipe. The protruding axial spiral lead ribs on the inner wall of the pipeline are capable of strengthening the pipe and effectively reducing the bamboo-like fracture of the pipeline caused by external shock.
Description
Technical field
The utility model belongs to structural material, relates in particular to a kind of hollow hush pipe.
Background technique
The demand of pipeline is very big in the construction industry; A lot of local conveying or the sewage emissions that all need carry out water with pipeline, present most of pipeline generally adopts single layer structure, and inner-walls of duct is smooth cambered surface; The existing shortcoming of the drainage pipe of this structure is: compressive strength is lower, low impact resistance a little less than; Most importantly when water trickles in drainage pipe,, cause drainage pipe can produce bigger noise in the course of the work owing to possibly contain impurity such as bubble, building materials granulated garbage in it; And the existence of these impurity also can influence the fluency of current, reduced working efficiency.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned existing technology, provides a kind of structure simple, can play the silencing pipeline for building of noise reduction, soundproof effect.
The utility model is realized through following technological scheme:
A kind of hollow hush pipe comprises pipeline, is provided with axial hole in the said tube wall, is positioned at inner-walls of duct and is provided with protruding axial screw guide rib.
The utility model has the advantages that: the noise that the utility model produces in the time of can effectively reducing draining.Because: be provided with axial hole in the said tube wall, can reduce pipe internal pressure and pressure surge, improved pipeline coefficient safe in utilization.Be positioned at inner-walls of duct and be provided with protruding axial screw guide rib.Not only have remarkable reinforing function, also can effectively reduce vertical bamboo appearance fracture phenomena that pipeline is caused by external impacts.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment: hollow hush pipe as shown in the figure, comprise pipeline 1, be provided with axial hole 2 in said pipeline 1 wall, be positioned at pipeline 1 inwall and be provided with protruding axial screw guide rib 3.Current under the guide functions of inner tube wall triangle spiral bar in the shape of a spiral shape fall, and under the double action of porous on the wall, can reduce the noise of pipe-line system greatly, drainage noise power is merely 50% of common tube.
Claims (1)
1. a hollow hush pipe comprises pipeline, it is characterized in that: be provided with axial hole in the said tube wall, be positioned at inner-walls of duct and be provided with protruding axial screw guide rib.
