Description
Technical field
The utility model relates to drainage equipment technical field, particularly a kind of waste pipe reducing noise.
Background technique
Along with the continuous progress of new material technology and the continuous generation of new material, plastic pipe substitutes the development trend that steel pipeline has become China's water & wastewater engineering for building application material gradually.Water & wastewater engineering for building has used the iron drain-pipe of the heaviness in a nearly century to be eliminated gradually, the substitute is new material plastic drain-pipe (such as pvc pipe), it have lightweight, conveying flow hydraulic condition is good, corrosion resistance by force, not easily blocking, non-corrosive, attractive in appearance, installation labor intensity is little, economic benefit very outstanding feature, obtain in building water supply and sewerage engineering at home at present and greatly develop and apply.
But along with the fast development of economic construction and the growing tension of land resources, high-rise gets more and more, and floor is more and more higher, due to the increase along with floor, the noise produced during plastic drainage pipeline draining is also increasing, in daily life, family is often subject to the interference of the singing of the stream gurgled, general is all by the singing of the stream transmitted in house waste pipe, although this flowing water sound is not very large, still brings certain impact to maintenance quiet domestic environment; Especially night, the noise produced during draining downward from high level, has a strong impact on the rest of people and the peacefulness in room.
Therefore a kind of appearance with the waste pipe reducing noise function is necessary.
Summary of the invention
The purpose of this utility model overcomes prior art defect, provides a kind of waste pipe effectively reducing noise in draining.
The technical solution of the utility model is:
Comprise the external pipe, intervalve and the inner tube that set gradually from outside to inside, wherein the inwall of intervalve is dentation.
The inwall of described inner tube arranges screw rib.
Described screw rib is three and evenly arranges.
The material of described external pipe and inner tube is rigid polyvinyl chloride, and the material of intervalve is high density polyethylene (HDPE).
The inner wall coarse coefficient of described inner tube is set to 1.5 ~ 2 times of the external pipe tube wall roughness coefficient.
The utility model relative to existing technologies, has following useful technique effect:
Waste pipe is set to three layers by the utility model, inner tube contacting fluid, and the inwall of intervalve is dentation, makes noise at middle tube wall interreflection, thus is repeatedly absorbed weakening, effective sound insulation; External pipe can effectively be protected, and increases bulk strength; So the utility model waste pipe is compared with conventional plastic pipeline (such as PVC pipeline), produce minimum noise, even can not produce noise, excellent noise reduction effect.The utility model avoids the noise of drainage pipe to the impact of environment of living, and can provide peace and quiet, comfortable environment for resident living.
Further, the utility model is by arranging screw rib, and when draining, current decline along the spiral inner wall of inner tube under the guiding of screw rib, can reduce the noise that water body causes due to unordered flowing shock waste pipe better.
Further, the utility model by evenly arranging three screw rib, make current evenly, noise reduction is better.
Further, the material of the utility model external pipe and inner tube is rigid polyvinyl chloride, the bulk strength of waste pipe is increased, and rigid polyvinyl chloride can bear higher water temperature; The material of intervalve is high density polyethylene (HDPE), has sound absorption qualities, promotes the effect of noise reduction; And rigid polyvinyl chloride and high density polyethylene (HDPE) facilitate production to make the utility model waste pipe, and cost is lower.
Further, the utility model is by increasing the inner wall coarse coefficient of inner tube, and when carrying out draining, water forms attached jet along coarse inwall, can increase anti-acoustic capability.
Accompanying drawing explanation
Fig. 1 is schematic cross section of the present utility model;
Fig. 2 is longitudinal section of the present utility model schematic diagram;
Wherein: 1-external pipe; 2-intervalve; 3-inner tube; 4-screw rib; 5-inwall.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
See Fig. 1 and Fig. 2, the utility model is a kind of multiple tube reducing noise, and pipeline mainly comprises external pipe 1, intervalve 2, inner tube 3, screw rib 4; And even roughness process is carried out to the inwall 5 of inner tube 3.
As depicted in figs. 1 and 2, the utility model mainly comprises external pipe 1, intervalve 2 and inner tube 3, wherein intervalve 2 is made up of absorbing sound and lowering noise material high density polyethylene (HDPE) (HDPE), and the inwall of intervalve 2 is dentation, namely there is projection, undulate inside its transverse section, make noise at the inwall interreflection of intervalve 2 like this, thus repeatedly absorbed weakening, increase anti-acoustic capability; External pipe 1 and inner tube 3 are made up of the rigid polyvinyl chloride that price is more cheap, make the bulk strength of the utility model pipeline increase like this, and rigid polyvinyl chloride can bear higher water temperature.So intervalve 2 can absorbing sound and lowering noise, inner tube 3 contacting fluid, outer tube 1 can protect impact, makes waste pipe can absorbing sound and lowering noise like this, has again enough intensity.
The inwall 5 of the inner tube 3 in the utility model equidistantly evenly arranges three inwardly protruded screw rib 4, the transverse section of screw rib 4 is trigonometric form, the material of screw rib 4 is the same with the material of inner tube 3, for rigid polyvinyl chloride material, and produce with inner tube 3 as a part for inner tube 3 simultaneously, the height of screw rib 4 suitably increases along with the increase of inner tube 3 caliber, highly be about 0.12 times of corresponding caliber, make water along screw rib 4 with under the form ordered flow of spiral flow, reduce the noise that water body causes due to unordered flowing shock waste pipe.Even roughness process is carried out to the inwall 5 of inner tube 3, increase the roughness coefficient of inwall 5, the roughness coefficient is made to increase to original 1.5 ~ 2 times, because inner tube 3 and external pipe 1 adopt identical materials and process to make, the roughness coefficient of both inwalls was identical originally, so the inwall 5 of inner tube 3 after treatment, its roughness coefficient is 1.5 ~ 2 times of external pipe 1 inner wall coarse coefficient, to change the fluidised form of current in waste pipe, form attached jet, water velocity is reduced, thus reaches the effect reducing noise.So screw rib and the inwall carrying out coarse process reduce the noise that current produce.
The mode of production of the utility model waste pipe is that existing co-extrusion technology is produced, and equipment is simple, easy to operate, also can adopt other production tech more simply and easily.
The utility model noise-reducing drain pipe, is divided into three layers, inner tube 3 contacting fluid, intervalve 2 sound insulation, and external pipe 1 is protected; Inner-walls of duct 5 axially evenly arranges three screw rib 4 along body; After inner-walls of duct 5 carries out even roughness process, the roughness coefficient increases.When carrying out draining, water is forming attached jet along coarse inwall 5, and declines along inwall 5 spiral under the guiding of screw rib 4; Compared with conventional plastic pipeline (such as PVC pipeline), the utility model provides convenient production, the lower-cost waste pipe with reduction noise function, effectively can reduce the noise in waste pipe, produce minimum noise, even noise can not produced, reach the object effectively reducing noise, solve the noise of drainage pipe to the problem of environmetal impact of living, peace and quiet, comfortable environment can be provided for resident living.
