The utility model discloses amortization tubular product for drainage adds the buffer layer that has the water conservancy diversion muscle on the basis of the pipe fitting main part that is equipped with the through-hole, and its outer layer is PVC cavity amortization tubular product, and when rivers punching press, the buffer layer has eliminated a part of noise of rivers, and rivers flow along the guide route of water conservancy diversion muscle simultaneously, has alleviated the punching press power degree of rivers to a great extent, and in addition, the pipe fitting main part that itself is equipped with the through-hole can reduce the noise that rivers punching press produced once more;

this amortization tubular product for drainage's noise cancelling effect is good, and its simple structure, it is convenient to install, uses reliably, however, because this tubular product has add the water conservancy diversion muscle in the pipeline is inside, can reduce the water pipe unit interval's the excessive water yield to a certain extent, simultaneously, because the surface of water undersize of water conservancy diversion muscle, so the water conservancy diversion effect is unsatisfactory, and simultaneously, the intensity of pipeline pipe wall is lower, for this reason, we have proposed a cavity spiral tubular product with the above-mentioned drawback of good solution.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cavity spiral tubular product to solve the problem that proposes among the above-mentioned background art.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a cavity spiral pipe, includes inner tube and outer tube, the inner tube is located inside the outer tube, form annular cavity between outer tube and the inner tube, the cavity is equipped with a plurality of buffering strips, the inner tube inner wall has a plurality of guide strips that are the heliciform and distribute along its length direction shaping, a plurality of guiding gutters have been seted up along its length direction to the inner tube inner wall.

Preferably, the buffering strip is three at least, and evenly distributed in the cavity, set up the arc wall with buffering strip looks adaptation on inner tube outer wall and the outer tube inner wall, buffering strip diameter is greater than the distance 5mm between inner tube outer wall and the outer tube inner wall, the buffering strip is the rubber material.

Preferably, the number of the water guide grooves is equal to that of the guide strips, the water guide grooves are in the same size, the cross sections of the water guide grooves and the guide strips are triangular, the water guide grooves are formed in the upper surfaces of the guide strips, and one side surface of each water guide groove and one side surface of each guide strip form an integral surface.

Has the advantages that:

(1) the utility model adds the diversion trench on one side of the diversion strip, which can increase the water passing amount in unit time of the pipeline, and greatly increases the water passing area on the diversion strip by combining one side surface of the diversion strip and one side surface of the diversion trench, thereby improving the water flow buffering effect;

(2) the utility model discloses, through setting up many buffering strips in the cavity between outer tube and inner tube, can strengthen the shock resistance ability of pipeline, prolong the life-span of pipeline.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a cavity spiral tubular product, includes inner tube 1 and outer tube 2, and inner tube 1 is located inside outer tube 2, forms annular cavity 3 between outer tube 2 and the inner tube 1, and cavity 3 is equipped with a plurality of

buffering strips

4, and 1 inner wall of inner tube has a plurality of guide strips 5 that are the heliciform and distribute along its length direction shaping, and a plurality of guiding gutters 6 have been seted up along its length direction to 1 inner wall of inner tube.

Wherein, buffering strip 4 is three at least, and evenly distributed is in cavity 3, set up the arc wall 7 with 4 looks adaptations of buffering strip on 1 outer wall of inner tube and the 2 inner walls of outer tube, 4 diameters of buffering strip are greater than the distance 5mm between 1 outer wall of inner tube and the 2 inner walls of outer tube, buffering strip 4 is the rubber material, when 2 outer walls of outer tube receive external collision, buffering strip 4 can play good cushioning effect, can prevent that the pipeline from warping and breaking, the heat exchange of 3 inside rivers of reducible pipeline of cavity and outside air, reducible aquatic heat runs off, cavity 3 can also play good syllable-dividing effect simultaneously.

The number of the water guide grooves 6 is equal to that of the guide strips 5, the cross sections of the water guide grooves 6 and the guide strips 5 are triangular, the water guide grooves 6 are formed in the upper surfaces of the guide strips 5, one side surface of each water guide groove 6 and one side surface of each guide strip 5 form an integral surface, water flows flow along the water guide strips 5 in a rotating mode, noise generated by the water flows is reduced, the water flow of the water guide grooves 6 in the pipeline in unit time can be increased, the water flow of the upper surfaces of the water guide strips 5 is increased, and therefore the noise is further reduced.

The working principle is as follows: the utility model discloses in the use, when 2 outer walls of outer tube receive external collision, buffering strip 4 can play good cushioning effect, can prevent that the pipeline from warping and breaking, the heat exchange of 3 reducible pipeline inside rivers of cavity and outside air, reducible aquatic heat runs off, cavity 3 can also play good syllable-dividing effect simultaneously, when the pipeline leads to water, rivers are along 5 rotatory flows of water guide strip, with the noise that reduces rivers and produce, the water capacity of unit interval in the 6 multiplicable pipelines of guiding gutter, increase the water capacity of 5 upper surfaces of water guide strip simultaneously, thereby further noise reduction.
