Abstract
The utility model discloses an environment -friendly low noise drainage pipe, including pipe inner wall, the pipeline outer wall, the pipe inner wall surface is the wave structure, and wave structure is inside to fill acoustical coating, is sandwich layer expanded material between pipeline outer wall and the pipe inner wall. The utility model discloses the noise cancelling effect that gives sound insulation is good, and compressive capacity is strong, can effectively solve the drainage pipe's of high -rise resident family noise problem.
Description
Technical field
The utility model relates to tubing field, particularly relates to a kind of environment protection type Low-noise drainage pipeline.
Background technique
Along with the development of the process of Chinese Urbanization, occurred increasing tall building, people rise day by day for the concern of sewerage system.There is very large noise problem in existing building water drain pipe fitting, brings great interference to the Working Life of resident.Building pipe noise source is mainly from flow velocity and the pressure produced of liquid in pipeline.Wherein flowing water noise mainly current and pipe friction and the noise produced and because of the noise that active cross-section size changes and water (flow) direction changes and produces.Duct noise produces and along pipeline transmission in pipeline.The noise that water flow impact waste pipe in drainage pipe and air pressure cause is large especially, destroys the living environment of resident, has had a strong impact on the rest of resident, live and work etc.
Model utility content
In order to solve waste pipe noise problem, the utility model provides a kind of environment protection type Low-noise drainage pipeline of sound insulation good muffling effect.
The utility model is achieved through the following technical solutions:
A kind of environment protection type Low-noise drainage pipeline, comprise pipeline outer wall, inner-walls of duct, described inner-walls of duct surface arranges wave structure, the inner filling quieter material of wave structure.
Further, foamed core layer is had between described inner-walls of duct and pipeline outer wall.
The beneficial effects of the utility model are: when vertically falling under drainage pipe flow direction median, the wave structure on inner-walls of duct surface produces certain resistance to current, play a buffer function, flow rate of water flow is reduced, avoid current directly to contact with tube wall simultaneously, reduce the noise of current, the quieter material of wave structure inside simultaneously, weaken current noise outwards to propagate, filling foamed core layer between inside and outside tube wall, improves the anti-pressure ability of tube wall, and has good sound-absorbing effect, noise is intercepted, strengthens noise reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The A-A sectional drawing of Fig. 2 Fig. 1;
Shown in figure: 1-pipeline outer wall, 2-foamed core layer, 3-inner-walls of duct, 31-foamed core layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As depicted in figs. 1 and 2, a kind of environment protection type Low-noise drainage pipeline, comprises pipeline outer wall 1, inner-walls of duct 3, described inner-walls of duct 3 arranges wave structure 31, the inner filling quieter material of wave structure 31, quieter material can adopt can sound insulation, damping and sound absorption viscoelastic material.When current fall vertically downward time, the wave structure 31 of inner-walls of duct 3 produces certain resistance to current vertically downward, plays a buffer function to current, thus reduces the noise that water impact and air pressure produces; There is quieter material wave structure inside, and the propagation for noise plays obstruct to a certain extent; Be foamed core layer 2 between pipeline outer wall 1 and inner-walls of duct 3, improve the anti-pressure ability of tube wall on the one hand, foamed core layer 2 has good sound-absorbing effect on the other hand, reaches the object of noise reduction further.
Claims (2)
1. an environment protection type Low-noise drainage pipeline, comprises pipeline outer wall (1), and inner-walls of duct (3), is characterized in that, described inner-walls of duct (3) arranges wave structure (31) on the surface, the inner filling quieter material of wave structure (31).
