Abstract

The utility model provides a hollow sound insulation pipeline, which is characterized in that: an axial through hole is positioned in intervals at the middle of a pipe wall; the utility model can absorb the sound of draining water in the pipe and effectively eliminates the pollution to the peripheral environment resulted from the noise in discharging water. Besides, the internal wall of the utility model remains the characteristic of smooth wall in single pipe, so that the fluid in the pipe can move smoothly and the blockade of pipe can be avoided. Because the axial through hole is positioned on the wall pipe of single pipe, the utility model reduces the quantity of materials, realizes low cost and high strength and can be taken as an ideal noise insulation pipe. Therefore, the utility model can be widely applied to industrial production and architectures to ensure quiet working and living environment for people.

Description

The hollow silencing pipeline

Technical field

The utility model relates to a kind of hollow pipeline, especially a kind of hollow pipeline of good muffling effect.

Background technique

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 overcoming 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 and can effectively abate the noise, and inner wall smooth is economized intensity height, the hollow silencing pipeline that cost is low with material.

The utility model is finished by following technical proposal: a kind of hollow silencing pipeline is characterized in that being provided with axial hole in the tube wall at interval, thereby effectively absorbs the noise from inwall.

The section configuration of the axial hole in the described tube wall is rectangle or triangle, and perhaps prismatic or polygonal are perhaps oval or circular.

The section configuration of the axial hole in the described tube wall is any one the single shape in rectangle, triangle, prismatic, polygonal, ellipse, the circle, perhaps is the combined shaped more than two kinds at least, to bring into play sound deadening to greatest extent.

Axial hole in the described tube wall is distributed on the tube wall section equably or anisotropically, to bring into play the sound-deadening and noise-reducing effect to greatest extent.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can absorption tube internal drainage sound, effectively eliminate the pollution that drainage noise causes surrounding environment, inwall of the present utility model has kept the characteristics of single tube inner wall smooth in addition, make the pipe in fluid can be unblocked, can not form pipe plug, owing to be on the tube wall of single tube, axial hole to be set, 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.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The hollow silencing pipeline that the utility model provides is provided with axial hole 2 in its tube wall 1, at interval as Fig. 1; The section configuration of wherein said axial hole is single ellipse 3, and is evenly distributed on the section, as Fig. 2; The section configuration of described axial hole also can be single rectangle 4, and anisotropically is distributed on the section, as Fig. 3; The section configuration of described axial hole is the combination of triangle 5 and oval 6, and anisotropically is distributed on the section, as Fig. 4.Thereby effectively absorb noise, to bring into play sound deadening to greatest extent from inwall.

Claims

1, a kind of hollow silencing pipeline is characterized in that being provided with at interval in the tube wall axial hole.

2, hollow silencing pipeline according to claim 1, the section configuration that it is characterized in that the axial hole in the described tube wall is rectangle or triangle, perhaps prismatic or polygonal are perhaps oval or circular.

3, hollow silencing pipeline according to claim 1, the section configuration that it is characterized in that the axial hole in the described tube wall is any one the single shape in rectangle, triangle, prismatic, polygonal, ellipse, the circle, perhaps is the combined shaped more than two kinds at least.
