Abstract
A muffling drainage pipeline used for building comprises a pipeline body (1), and is characterized in that a pipeline body (1) includes an outer pipeline (2), an inner pipeline (3) and annual reinforcing ribs (4) arranged between the outer and the inner pipelines, and flow guiding ribs (5), each of which the height is one fifth to one third of the diameter of the inner pipeline, are arranged on the inner wall of the inner pipeline (3) along the axial direction of the pipeline body (1). The pipeline has the advantages of simple structure, novel design, capability of sound attenuation and insulation, heavy pressure resistant intensity, good impact resistance and the like.
Description
Technical field:
The utility model relates to a kind of water pipe, and is especially a kind of simple in structure, and modern design can play noise reduction, soundproof effect, and compressive strength is big, the noise reduction drainage pipe for building of strong shock resistance.
Background technique:
In construction industry, drainage pipe is the very large structural material of a kind of demand always, a lot of local conveyings that all need to carry out water with drainage pipe, perhaps sewage emissions, but existing drainage pipe generally adopts single layer structure, inner-walls of duct is smooth cambered surface, the existing shortcoming of the drainage pipe of this structure is: compressive strength is lower, low impact resistance a little less than, most importantly when water trickles in drainage pipe, owing to may contain bubble in it, impurity such as building materials granulated garbage, cause drainage pipe can produce bigger noise in the course of the work, and the existence of these impurity also can influence the fluency of current, reduced working efficiency.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, and modern design can play noise reduction, soundproof effect, and compressive strength is big, the noise reduction drainage pipe for building of strong shock resistance.
Technical solution of the present utility model is: a kind of noise reduction drainage pipe for building, comprise pipe body 1, it is characterized in that: described pipe body 1 is by outer layer pipe 2, inner layer pipe 3 and be arranged on annular between the two and strengthen raised line 4 and form, the inwall upper edge pipe body 1 of inner layer pipe 3 axially is provided with water conservancy diversion raised line 5, and the height of water conservancy diversion raised line 5 is 1/5 to 1/3 of an inner layer pipe diameter.
Described water conservancy diversion raised line 5 helicals are arranged on the inwall of inner layer pipe 3, and are a plurality of, are equally spaced.
Equidistantly be provided with a plurality of auxiliary water conservancy diversion raised lines 6 between per two adjacent water conservancy diversion raised lines 5, it highly is 1/3 of a water conservancy diversion raised line 5.
The section of described water conservancy diversion raised line 5 is triangle or semicircle.
The section of described auxiliary water conservancy diversion raised line 6 is triangle or semicircle.
It is a plurality of that described annular is strengthened raised line 4, and is equally spaced in the space of outer layer pipe 2 and inner layer pipe 3 formation.
The utility model is compared with prior art, has following advantage:
1. the noise that produces in the time of can effectively reducing draining.Since its with inwall that current contact on axially be provided with spiral helicine water conservancy diversion raised line, can avoid because of being entrained with smooth phenomenon of current that bubble and impurity causes in the current, thereby reduce noise.
2. adopt annular to strengthen the mode that raised line supports double-skin duct, can strengthen the compressive strength of pipeline, further improve impact resistance, under the condition that reaches same compressive strength and impact resistance, cost is lower, helps applying, and possesses extensive market prospects.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 be the utility model embodiment A-A to sectional view.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2: a kind of noise reduction drainage pipe for building, comprise pipe body 1, pipe body 1 is by outer layer pipe 2, inner layer pipe 3 and be arranged on annular between the two and strengthen raised line 4 three parts and forms, and this inside and outside layer of double layer construction can effectively improve the intensity and the impact resistance of pipe body; The inwall upper edge pipe body 1 of inner layer pipe 3 axially is provided with water conservancy diversion raised line 5, specifically, water conservancy diversion raised line 5 helical setting vertically, water conservancy diversion raised line 5 is a plurality of, number is good with 8, and be equally distributed on inner layer pipe 3 inwalls, in the time of in current pass through inner layer pipe 3, water conservancy diversion raised line 5 can play the effect of pilot flow direction; The height of water conservancy diversion raised line 5 is 1/5 to 1/3 of an inner layer pipe diameter, is good with 1/4;
Equidistantly be provided with a plurality of auxiliary water conservancy diversion raised lines 6 between per two adjacent water conservancy diversion raised lines 5, it highly is 1/3 of a water conservancy diversion raised line 5, and the effect of auxiliary water conservancy diversion raised line 6 is the same with the effect of water conservancy diversion raised line 5, can play the effect of guiding to current.
The section of described water conservancy diversion raised line 5 and auxiliary water conservancy diversion raised line 6 is triangle or semicircle, and in general, if the impurity in the drainage pipe is less, when current were clear, using section was that leg-of-mutton water conservancy diversion raised line 5 and auxiliary water conservancy diversion raised line 6 effects are better; When the current of the drainage pipe of flowing through are muddy, when it contained more impurity, using section was that semicircular water conservancy diversion raised line 5 and auxiliary water conservancy diversion raised line 6 effects are better;
Because therefore the existence of water conservancy diversion raised line 5 and auxiliary water conservancy diversion raised line 6 when current are flowed through water pipe, can effectively reduce the noise that current produce.
The quantity that is clipped in the annular reinforcement raised line 4 between outer layer pipe 2 and the inner layer pipe 3 is a plurality of, and is equally spaced in the space of outer layer pipe 2 and inner layer pipe 3 formation, so just can adapt to the bigger environment of impact force.
