Abstract
A rectangular hollow-wall sound absorbing pipe comprises a pipe wall with rectangular section and is characterized in that axial through holes are alternately arranged inside the pipe wall. The rectangular hollow-wall sound absorbing pipe is capable of absorbing sound of discharging water inside the pipe, and effectively eliminating pollution to surroundings caused by water discharging noise. Further, the rectangular hollow-wall sound absorbing pipe is coated around ordinary delivery pipelines, can achieve fine sound insulation effect without changing or replacing shape or material of the pipeline, has minimum used material, low cost and high strength, and is an ideal noise eliminating pipe widely applicable to industrial production and constructions, thereby providing a silent work and living environment to people.
Description
Technical field
The utility model relates to a kind of building pipe, and particularly a kind of hush pipe belongs to sound insulation silencing pipeline technical field.
Technical background
Along with the raising of science and technology development and people's living standard, not only require living conditions to be improved and improve, as live in spaciousness, bright house, but also require to live and good work environment, with fresh air, clean, no flue gas, waste gas, dust pollution, noise free pollutes.Noise in the middle of this mainly refers to the noise that mobile object is produced in factory or the architecture pipe.With regard to present conveyance conduit, mostly be single tube greatly, when its in the process of transport flow object, all can produce bigger noise, and this noise is almost to the sky transmitted out entirely, cause the noise pollution of surrounding environment.The producer that for this reason has is at the big problem of single tube noise, produce double walled ducting or three layers of composite PVC pipe,, have inner wall coarse though can eliminate partly noise, pipeline circulation ability, have some setbacks deficiency, especially consume materials such as easy obstruction, the cost height, problems such as price is expensive are that pipeline user institute is unacceptable, are difficult to be used widely.Therefore, be necessary fully prior art is improved.
Summary of the invention
Big for solving the noise that has the waste pipe existence now, inner wall coarse, consumptive material, the high deficiency of cost, the utility model provides a kind of can effectively completely cut off noise, hush pipe with low cost.
The utility model is finished by following technical proposal: a kind of rectangular hollow wall hush pipe comprises the tube wall of rectangular cross-section it is characterized in that being interval with in the tube wall axial hole.Thereby effectively absorb noise from inwall.
The section configuration of the axial hole that is provided with at interval in the described tube wall is circle or ellipse or polygonal, to improve erasure effect.
The axial hole that is provided with at interval in the described tube wall evenly or anisotropically is distributed in the tube wall, so that the noise in the effectively isolated pipeline.
Described inner tube wall is provided with stiffening rib, so that improve the intensity of hush pipe, improves erasure effect simultaneously.
Stiffening rib on the described inner tube wall is made as axially vertically stiffening rib, perhaps is made as spirality or intersects webbed stiffening rib along inner tube wall, so that improve the intensity of hush pipe.
The utlity model has following advantage and effect: adopt such scheme, can absorption tube internal drainage sound, effectively eliminate drainage noise to the pollution that surrounding environment causes, need not to change or change the shape and the material of pipeline, just can reach good soundproof effect, and this sound insulation pipe is not only few with material, cost is low, and the intensity height is that a desirable noise is eliminated pipe, can be widely used in the industrial production and on the building, people can be in quiet work and the living environment.

Specific embodiments
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
The rectangular hollow wall hush pipe that the utility model provides, the tube wall 1 that comprises the rectangular cross-section, be interval with axial hole 4 in the tube wall 1, the section configuration of axial hole 4 is a rectangle, and be evenly distributed in the tube wall 1, inner tube wall 2 is provided with stiffening rib 3, and stiffening rib 3 is made as axially vertically stiffening rib, as Fig. 1, Fig. 2.
Described stiffening rib is made as spirality 5 along inner tube wall, and as Fig. 3, Fig. 4, all the other structures are the same.
Described stiffening rib is made as cross network 6 along inner tube wall, and as Fig. 5, Fig. 6, all the other structures are the same.
