Abstract

The utility model relates to a silencing PVC (polyvinyl chloride) drainage pipe, which belongs to the technical field of drainage pipes. The silencing PVC drainage pipe comprises a pipe body and a drainage groove, wherein the drainage groove is arranged on the inner surface of the pipe body, and 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 uniformly arranged between the inner pipe and the outer pipe, the drainage groove is spiral, the end surface of the drainage groove is triangular, and each silencing hole is circular or polygonal. The silencing PVC drainage pipe has the beneficial effects of simple structure, easiness in manufacturing and capability of effectively reducing noise through the drainage groove for guiding water flow and the silencing holes between the inner pipe and the outer pipe.

Description

A kind of noise reduction PVC gutter
Technical field
The utility model relates to the drainage pipe technical field, especially relates to a kind of noise reduction PVC gutter.
Background technology
Along with the continuous progress of new material technology, " to mould Dai Gang " substitute technology has become China's building water supply and drainage practical applications Development of Materials trend.The building water supply and drainage engineering has used the iron drain-pipe of the heaviness in a nearly century to be eliminated gradually; The substitute is new material PVC gutter; It has in light weight, carry that fluid resistance is little, corrosion resistance strong, be difficult for obstruction, non-corrosive, installation labour intensity are little, economic benefit outstanding feature very, obtained at home at present greatly developing and using.
Along with the fast development of economic construction, high-rise building is more and more, and floor is increasingly high; Also produced some worries for simultaneously people; Because along with the increase of floor, the noise that produces during its drainage pipe draining is also opened bigger and bigger, especially night; The noise that produces during from the downward draining of high level has a strong impact on people's the rest and the peacefulness in room.Therefore a kind of appearance of the PVC gutter with silencing function is necessary.
The utility model content
The utility model is to provide a kind of noise reduction PVC gutter for solving the problems of the technologies described above.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of noise reduction PVC gutter; Comprise body and drainage trough; Said drainage trough places said inner surface of tube body, it is characterized in that: pipe and outer tube in said body comprises evenly are provided with several bloops between pipe and the said outer tube in said; Said drainage trough is a helical form, and the end face of said drainage trough is a triangle.
Said bloop is circle or polygon.
The helical angle of said drainage trough is between 12~70 °.
Said body and said drainage trough are the PVC material.
The beneficial effect that the utlity model has is: simple in structure, easy to manufacture, can effectively reduce noise through the bloop between drainage trough direct water and the interior tube and tube.
Description of drawings
Fig. 1 is the utility model: a kind of structural representation of noise reduction PVC gutter;
Fig. 2 is the utility model: a kind of schematic cross-section of noise reduction PVC gutter.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
With reference to shown in Figure 1, a kind of PVC gutter comprises body 1 and drainage trough 2, and body 1 is the PVC material with drainage trough 2, and pipe 11 and outer tube 12 in body 1 comprises evenly are provided with several bloops 13 between interior pipe 11 and outer tube 12; On the inner surface of pipe 11, drainage trough 2 was a helical form in drainage trough 2 evenly distributed, and the end face of drainage trough 2 is a triangle.
Bloop 13 is circle or polygon.
The quantity of drainage trough 2 is several, and the helical angle of drainage trough 2 is between 12~70 °.
When the waste water in the gutter from a high position to the process that low level falls; Drainage trough is to the shunting of the wastewater step in the pipe; Because drainage trough is a helical form; Waste water is downward along the spiral inner wall of interior pipe, thereby has reduced the mutual bump number of times of current in pipe, and then the water and the tube wall that have reduced generation when draining is impacted downwards clash into the noise that is produced each other; Because body is made up of interior pipe and outer tube, middle interlayer also has certain isolation to noise, further realizes reducing the effect of noise.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

Claims (3)

1. noise reduction PVC gutter; Comprise body and drainage trough, said drainage trough places said inner surface of tube body, it is characterized in that; Pipe and outer tube in said body comprises; In said, evenly be provided with several bloops between pipe and the said outer tube, said drainage trough is a helical form, and the end face of said drainage trough is a triangle.
2. a kind of noise reduction PVC gutter according to claim 1, it is characterized in that: said bloop is circle or polygon.
