Abstract
The utility model discloses a hollow spiral noise reduction tube, relates to the technical field of tubing, and aims to overcome the defect that noise cannot be eliminated fundamentally in an existing ordinary upright drain pipe. The hollow spiral noise reduction tube is a cylindrical body with an annular cavity, and the cylindrical body is composed of an inner tube wall and an outer tube wall. A plurality of support ribs are evenly arranged between the inner tube wall and the outer tube wall along the circumferential direction, the annular cavity is divided into a plurality of holes by the support ribs, a plurality of water guiding walls are arranged on the inner surface of the inner tube wall, the inner surface of the inner tube wall faces toward a central axis, the water guiding walls are protruding ribs distributed spirally around the axis, the cross section of each water guiding wall is triangular in shape, and the number of the water guiding walls is eight. The hollow spiral noise reduction tube is especially suitable for noise reduction drainage systems inside buildings.
Description
Technical field
The utility model relates to the tubing technical field, relates in particular to a kind of hollow helical silencing pipe that is used for construction engineering.
Background technique
The continuous reinforcement of Along with people's environmental consciousness and to the unremitting pursue of HQ high quality, high-grade living environment, noise problem becomes the focus that people pay close attention to gradually.The noise that the used vertical drainage pipe of residential building is produced when draining make resident's life lack due quiet, destroyed resident's living atmosphere, especially at night, the ill effect that this noise produced is more obvious.The PVC-U pipe has solved the problem of corrosivity, aesthetic property and obstruction property well, but its noise problem seems especially outstanding.
Fluid produces noise in the flow process in common riser factor is following:
The impact to tube wall that forms when one, fluid flows in pipe produces noise thereby the vibrations that this impact produced cause sympathetic response;
Two, be entrained in the path that air in the fluid does not have smooth and easy discharge, this causes on the one hand and postpones the speed that current fall, thereby produces the bump of water droplet successively and produce noise, and water impact gas also can cause gas shock and produce noise simultaneously;
Three, current fall to impact tube wall, the water droplet that a part is rebounded with after extremely current also can produce bump and trigger noise.
More than be common vertical waste pipe produces noise when draining some factors.Structure and material through improving tubing can reduce generation of noise in the drainage procedure to a certain extent, but this mode can only reduce and can not eliminate, and are not the optimum scheme that fundamentally solves the noise problem that the waste pipe of various materials all exists.
The model utility content
To the problem that existing common vertical waste pipe can not fundamentally abate the noise, the purpose of the utility model provides a kind of hollow helical silencing pipe.
The utility model solves the technological scheme that its technical problem adopted: its cylindrical shell with ring cavity for being made up of an inner tubal wall and an outer tube wall; Between said inner tubal wall and said outer tube wall, along the circumferential direction be evenly equipped with some supporting ribs; Said supporting rib is divided into some holes with said ring cavity; The internal surface towards central axis of said inner tubal wall is provided with some water guide walls; Said water guide wall is that the cross section of said water guide wall is triangular in shape, and the quantity of said water guide wall is eight around the axis convex tendon that distributes of shape in the shape of a spiral.
Further, the angle of said water guide wall and said hush pipe central axis is 9 °～15 °.
Preferably, the top rounding off of the cross-sectional triangle of said water guide wall.
Preferably, the thickness of said inner tubal wall is less than the thickness of said outer tube wall.
The effect of this patent is:
One, soundproof effect is obvious: be shaped on linearly oblique eight spiral convex ribs that are uniformly distributed with on the hush pipe inner tubal wall; Current are discharged along pipe material inner wall by the oblique straight line of spiral convex rib under the water conservancy diversion of spiral convex rib, have reduced the collision of the air and the tube wall of current and irrgular movement; The direction of standard fluid; Can not produce stronger impact, thereby reduce noise, reach the effect of noise reduction its inwall.It can reduce by 8～10 decibels than standard solid wall pipe, has contained the noise that in the effluent discharge process, is produced really.
Two, reduce resistance to water-flow: the current in the soil stack are tangible attached jet, have reduced water velocity, reduce the water resistance coefficient; Make up/down perforation, steadily manage the internal pressure fluctuation, improved the logical ability of row of standpipe; Reduced air displacement, the logical ability of row increases, and tolerance reduces about 15～20%.
Three, increase tubing intensity: owing in the hush pipe unimpeded air column is arranged; Reduced the pressure surge of pipe internal pressure; Improved pipeline coefficient safe in utilization, eight triangle spiral convex ribs of inner tube wall have significant reinforing function, can reduce effectively that pipeline receives external impacts and the fracture phenomena that causes.
Four, the cost expense is low: this hush pipe water displacement is big, increases by 1/3 than common specification tubing water displacement, thereby has reduced cost of material in a large number, has practiced thrift mounting costs such as manual work, and overall cost reduces more than 30%, can increase indoor utilization area simultaneously.

Embodiment
The hollow helical silencing pipe 100 of the utility model is described in conjunction with Fig. 1; The cylindrical body with ring cavity of tube wall for constituting by an inner tubal wall 102 and an outer tube wall 101; Between inner tubal wall 102 and outer tube wall 101, be evenly equipped with some supporting ribs 103 vertically, supporting rib 103 is solidified as a whole with inside and outside tube wall and ring cavity is divided into some holes.On the internal surface of hush pipe central axis, be provided with some water guide walls 104 at inner tubal wall 102.Water guide wall 104 is around the axis convex tendon that distributes of shape in the shape of a spiral, and water guide wall 104 quantity are eight.Water guide wall 104 cross sections are triangular in shape, this leg-of-mutton top rounding off.Water guide wall 104 is 9 °～15 ° with the angle of hush pipe central axis.The thickness of inner tubal wall 102 is less than the thickness of outer tube wall 101.
The angle of swing of water guide wall (being designed to α≤73 °) like the right-handed thread lift angle, in vertical drainage system was used, the current of the helical silencing pipe 100 of flowing through were along water guide wall 104 helical flow of inner tube wall; Reduced the collision of current and air; Avoided the mix in the flow process, the direction of standard fluid reduces " water hammer " influence; Alleviated the impact of current to tube wall; And under the double action of porous tube wall, reducing the noise of pipe-line system greatly, the comparable common tube of draining noise power reduces by 50%.Simultaneously,, so just formed an intermediate air path, realized the smooth and easy discharge of gas in the vertical drainage procedure preferably, thereby avoided the noise that brings out therefrom in discharge pipe line central authorities because current are dirty along inner tube wall spiral rule.In addition; Owing to improved the ventilation capacity of vertical drainage system; Eliminated the air pressure resistance when current fall, current form stable and closely knit current along the discharge pipe line inwall, thereby have improved water passing capacity greatly; The good aeration ability has also realized the stable of pressure in the system, makes the safety in utilization of drainage system to be able to bigger raising.
Those skilled in the art will recognize that; Above-mentioned embodiment is exemplary; Be in order to make those skilled in the art can better understand this patent content; Should not be construed as is the restriction to this patent protection domain, changes or modifies so long as disclose spiritual any being equal to of being done according to this patent, all falls into this patent protection domain.
