Abstract
The utility model relates to a wedge type spiral sound-reduction pipe, comprising a pipe body (1). The inner wall (2) of the pipe body (1) is provided with wedges (3) or wedges (4) along the longitudinal direction by spiraling downwards; at least two of the wedges (3) or the wedges (4) are parallelly arranged, and the top end of each of the wedges (3) is a flat top; the top end of each of the wedges (4) is a sharp top; the parallel wedges (3) or wedges (4) form a unit; the wedge type spiral sound-reduction pipe is provided with at least three units or more than three units. The sound reduction function of the sound absorption wedges come from a plurality of times of reflections between two adjacent wedges, most part of sound is absorbed during the plurality of times of reflection and only weakest sound is reflected, thereby achieving the purpose of sound reduction of the pipe; and the wedge type spiral sound-reduction pipe has a reasonable structure, better solves the technical problem that the noise of the pipe can not be solved, and further improves the living quality of people.
Description
Technical field
The utility model relates to a kind of flat tubing, and particularly a kind of splitter formula spiral flat tubing belongs to the manufacturing and the applied technical field of drainage pipe for building.
Background technique
What existing drainage pipe use for building was commonplace is normal straight tube tubing.The tubing of this spline structure is when draining, and owing to the bump between current and current, between current and tube wall makes current smooth inadequately, the noise that it produced has seriously influenced people's quality of life.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of rational in infrastructure, the bump of current in the time of can farthest reducing draining, and then the novel splitter formula spiral flat tubing of reduction noise.
For achieving the above object, the utility model adopts following technical proposals: splitter formula spiral flat tubing, comprise body (1), and the inwall (2) of body (1) longitudinally and under the screw is shaped on splitter (3) or splitter (4).(4) at least two of above-mentioned splitter (3) or splitters are arranged side by side, and the top of splitter (3) is a flat-top shape; The top of splitter (4) is a cusp configuration.Between above-mentioned splitter arranged side by side (3) and splitter (3) or be a unit between splitter (4) and splitter (4), the utility model is established three unit or three above unit at least.
Flat principle of the present utility model: splitter is to be made of the base portion and the portion of splitting.The portion of splitting is that the cross section begins augmenting portion gradually from tip.Because the portion of the splitting cross section of sound absorption splitter increases gradually from little, make between current and current, between current and tube wall and the Strike note major part between current and air absorbed gradually, have only a fraction of sound wave to be reflected.Specifically, the flat effect of above-mentioned sound absorption splitter comes from sound repeatedly reflection between adjacent two splitters, makes the sound of the overwhelming majority repeatedly be absorbed in the reflection, has only extremely weak sound to be reflected, thereby has reached the flat purpose of tubing.If adopt quieter material to make tubing, its flat effect can be more obvious.
Inwall of the present utility model is owing to adopted splitter formula helix structure, it is rational in infrastructure, greatly reduced the Strike note between current and current, current and tube wall and current and air, and then reduced the noise of pipe-line system, the noise that has solved tubing preferably can not get the technical barrier that solves for a long time, thereby has improved people's quality of life.
Description of drawings
Fig. 1 is that the utility model is the cross sectional representation of flat-top shape splitter structure, also is embodiment 1 of the present utility model.
Fig. 2 is that the utility model is the cross sectional representation of cusp configuration splitter structure, also is embodiment 2 of the present utility model.
Fig. 3 is embodiment 3 of the present utility model.
Fig. 4 is the utility model longitudinal profile schematic representation.
Embodiment
With reference to Fig. 1, splitter formula spiral flat tubing comprises body 1, and the inwall 2 of body 1 longitudinally and under the screw is shaped on splitter 3.Above-mentioned splitter 3 be two side by side, and the top of splitter 3 is flat-top shapes.3 of above-mentioned splitter arranged side by side 3 and splitters are a unit, establish six unit altogether.
With reference to Fig. 2, splitter formula spiral flat tubing comprises body 1, and the inwall 2 of body 1 longitudinally and under the screw is shaped on splitter 4.Above-mentioned splitter 4 be three side by side, and the top of splitter 4 is cusp configurations.4 of above-mentioned splitter arranged side by side 4 and splitters are a unit, establish six unit altogether.
With reference to Fig. 3, splitter formula spiral flat tubing comprises body 1, and the inwall 2 of body 1 longitudinally and under the screw is shaped on splitter 4.Above-mentioned splitter 4 be three side by side, and the top of splitter 4 is cusp configurations.4 of above-mentioned splitter arranged side by side 4 and splitters are a unit, establish 12 unit altogether.
Among Fig. 41 is body; 2 is tube wall; 4 is the cusp configuration splitter.
Described in the foregoing description 1-3, element number the best is 6 unit or 12 unit (not being subjected to splitter still is that the quantity of cusp configuration and splitter is limit by flat-top shape) between splitter arranged side by side and splitter.
Claims (2)
1. splitter formula spiral flat tubing, comprise body (1), it is characterized in that: the inwall (2) of described body (1) longitudinally and under the screw is shaped on splitter (3) or splitter (4), and (4) at least two of above-mentioned splitter (3) or splitters are arranged side by side, and the top of splitter (3) is a flat-top shape; The top of splitter (4) is a cusp configuration, between above-mentioned splitter arranged side by side (3) and splitter (3) or be a unit between splitter (4) and splitter (4), is provided with three unit or three above unit at least.
2. splitter formula spiral flat tubing as claimed in claim 1 is characterized in that: set element number the best is 6 unit or 12 unit between above-mentioned splitter arranged side by side (3) and splitter (3) or splitter (4) and splitter (4).
