Abstract
The utility model belongs to the technical field of drainage pipes, and relates to a silencing PVC (polyvinyl chloride) drainage pipe. The silencing PVC drainage pipe comprises a pipe body and drainage grooves, and the drainage grooves are disposed in the inner surface of the pipe body. The silencing PVC drainage pipe is characterized in that the pipe body comprises an inner pipe and an outer pipe, a plurality of silencing holes are formed between the inner pipe and an outer pipe uniformly, end faces of the drainage grooves which are spiral are triangular, and the silencing holes are round or polygonal. The silencing PVC drainage pipe has the advantages of being simple in structure, easy to manufacture, and capable of reducing noise by water flow guiding of the drainage grooves and through the silencing holes between the inner pipe and the outer pipe.
Description
Technical field
The utility model relates to drainage pipe technical field, especially relates to a kind of noise reduction PVC waste pipe.
Background technique
Along with the continuous progress of new material technology, " to mould Dai Gang " substitute technology has become the development trend of China's water & wastewater engineering for building application material.Water & wastewater engineering for building has used the heavy iron drain-pipe in a nearly century to be eliminated gradually, the substitute is new material PVC waste pipe, it have lightweight, carry little, the corrosion resistance of fluid resistance strong, be difficult for that obstruction, non-corrosive, installation labor intensity are little, very outstanding feature of economic benefit, obtained at home at present greatly developing and applying.
Along with the fast development of economic construction, high-rise is more and more, and floor is more and more higher, also produced some worries to people simultaneously, due to the increase along with floor, the noise producing during its drainage pipe draining is also opened larger and larger, especially night, the noise producing during from the downward draining of high level, has a strong impact on people's rest and the peacefulness in room.Therefore a kind of appearance of the PVC waste pipe with silencing function is necessary.
Model utility content
The utility model, for solving the problems of the technologies described above, is to provide a kind of noise reduction PVC waste pipe.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of noise reduction PVC waste pipe, comprise body and drainage trough, described drainage trough is placed in described inner surface of tube body, it is characterized in that: described body comprises inner and outer tubes, between described inner tube and described outer tube, be evenly provided with several bloops, described drainage trough is helical, and the end face of described drainage trough is triangle.
Described bloop is circle or polygonal.
The helix angle of described drainage trough is between 12～70 °.
Described body and described drainage trough are PVC material.
The beneficial effect the utlity model has is: simple in structure, easy to manufacture, and by drainage trough, guide the bloop between current and interior tube and tube can effectively reduce noise.
Accompanying drawing explanation
Fig. 1 is the utility model: a kind of structural representation of noise reduction PVC waste pipe;
Fig. 2 is the utility model: a kind of schematic cross-section of noise reduction PVC waste pipe.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1, a kind of PVC waste pipe, comprises body 1 and drainage trough 2, and body 1 and drainage trough 2 are PVC material, and body 1 comprises inner tube 11 and outer tube 12, is evenly provided with several bloops 13 between inner tube 11 and outer tube 12; Drainage trough 2 is uniformly distributed on the internal surface of inner tube 11, and drainage trough 2 is helical, and the end face of drainage trough 2 is triangle.
Bloop 13 is circle or polygonal.
The quantity of drainage trough 2 is several, and the helix angle of drainage trough 2 is between 12～70 °.
When the process that the waste water in waste pipe falls from a high position to low level, drainage trough is progressively shunted the waste water in pipe, because drainage trough is helical, waste water is downward along the spiral inner wall of inner tube, thereby reduced the mutual shock number of times of current in pipe, and then reduced when draining is impacted the water and the tube wall that produce downwards and mutually clash into produced noise; Because body is comprised of inner and outer tubes, middle interlayer also has certain isolation to noise, further realizes the effect that reduces noise.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. a noise reduction PVC waste pipe, comprise body and drainage trough, described drainage trough is placed in described inner surface of tube body, it is characterized in that, described body comprises inner and outer tubes, between described inner tube and described outer tube, be evenly provided with several bloops, described drainage trough is helical, and the end face of described drainage trough is triangle.
2. a kind of noise reduction PVC waste pipe according to claim 1, is characterized in that: described bloop is circle or polygonal.
