Abstract
The utility model discloses a spiral muffling drain pipe which relates to drainage pipeline field and is applied in a drainage pipeline of an industrial or civilian building. The spiral muffling drain pipe comprises an outer pipe body and an inner pipe body which is connected at the interior of the outer pipe body and is provided with a spiral flow guide rib. The cross section of the spiral flow guide rib is approximately triangular, and the two surfaces of the spiral flow guide rib, unconnected with the inner pipe body, are respectively a rebound surface and an interference surface; wherein the rebound surface is a convex circular arc surface; the interference surface is a concave circular arc surface; and a transitional circular arc surface is connected between the interference surface and the inner pipe body. Compared with prior art, the spiral muffling drain pipe has better muffling effect and is applicable in the drainage pipeline of industrial or civilian buildings, particularly the drainage pipeline with high muffling requirement; and under the condition of being made of the same material, the spiral muffling drain pipe has higher strength.
Description
Technical field
The utility model relates to the drainage pipe field, relates in particular to a kind of helical silencing gutter.
Background technology
Be used for the gutter of industry or civilian (dwelling house) building in the prior art, divide by its function, have two big classes on the market: a kind of is common rigid polyvinyl chloride (PVC) gutter; Another kind of is the helical silencing gutter with silencing function.The spiral rib quantity of the common helical silencing gutter of prior art is few, for example: the Dn110 specification only is that 6, Dn160 specification only are 8, the screw geometry face of rib is unreasonable, muscle face shape mostly is an equilateral triangle, spiral rib insufficient height, the highest general height only is 2.5mm, and therefore, the effect of noise abatement sound is undesirable.Development along with society, people are to the requirement of eliminating noise and the understanding that environment requirement has been had renewal, understanding to the noise effect health has had further raising, and the gutter of reform traditional or the little gutter of reform noise abatement audio fruit have become current an urgent demand.
The utility model content
In view of this, technical problem to be solved in the utility model is: a kind of reasonable in design, better helical silencing gutter of erasure effect is provided.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of helical silencing gutter, comprise outer tube body, it is inner and have an interior tube body of spiral stream guidance muscle to be connected in described outer tube body, the cross section summary of described spiral stream guidance muscle is triangular in shape, its two faces that are not connected with interior tube body are respectively rebound surface and interference surface, and wherein, described rebound surface is the arc surface of projection, described interference surface also is connected with the transition circle cambered surface for recessed arc surface between described interference surface and the interior tube body.
As preferably, the direction of described spiral stream guidance muscle is dextrorotation.
As preferably, the spiral angle of described spiral stream guidance muscle is 4 °～10 °.
As preferably, the spiral angle of described spiral stream guidance muscle be 7 ° 8 '.
As preferably, the muscle height of described spiral stream guidance muscle is 2.8～8mm.
As preferably, the arc radius of described rebound surface, transition circle cambered surface and interference surface is followed successively by 17mm, 15mm and 4mm.
As preferably, the arc radius of described rebound surface, transition circle cambered surface and interference surface is followed successively by 24.8mm, 21.5mm and 5.8mm.
As preferably, the bar number of described spiral stream guidance muscle is 11 or 16.
As preferably, the material of described helical silencing gutter is low foaming rigid polyvinyl chloride.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is set to the arc surface of projection by the rebound surface of spiral stream guidance muscle, not only can effectively play cushioning effect, be beneficial to current after the buffering simultaneously and take advantage of a situation and slide, thereby avoid in the process of buffering produces than impact sound greatly to current; And because the setting of interference surface and transition circle cambered surface makes the path of the caused reverse current of buffering more level and smooth, thereby avoided the big impact sound that produced in the counter-current process, and recessed circular arc interference surface more can effectively stop current.Simultaneously, the utility model adopts the low foaming rigid polyvinyl chloride material with soundproof effect to make, noise reduction adds sound insulation, make the utility model more obvious than the erasure effect of the helical silencing gutter of prior art, the drainage pipe that can be widely used in industry or civilian construction, especially the demanding drainage pipe of noise reduction, under the same material situation, tubing intensity is also higher.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of helical silencing gutter of the present utility model.
The specific embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only for reference with the explanation, be not to be used for the utility model is limited.
See also shown in Figure 1, the utility model provides a kind of helical silencing gutter, comprise outer tube body 1, it is inner and have an interior tube body 2 of spiral stream guidance muscle 3 to be connected in described outer tube body 1, the cross section summary of described spiral stream guidance muscle 3 is triangular in shape, its two faces that are not connected with interior tube body are respectively rebound surface r3 and interference surface r2, wherein, described rebound surface r3 is the arc surface of projection, described interference surface r2 also is connected with transition circle cambered surface r1 for recessed arc surface between described interference surface r2 and the interior tube body 2.Wherein, the direction of described spiral stream guidance muscle 3 is dextrorotation, and its spiral angle is 4 °～10 °, the spiral angle of described in the present embodiment spiral stream guidance muscle be 7 ° 8 '.When the part current of being arranged, directly fall within rebound surface r3, after bounce-back, it is moving to carry over the transition arc surface current, after passing through the counter-force effect of interference surface r2 arc surface again, water velocity and drag force obtain certain counteracting interferes, and through the dispersion buffering of each uniform bar spiral stream guidance muscle, thereby obtains effectively sound deadening.Wherein, the muscle height of described spiral stream guidance muscle can adopt 2.8mm～8mm.In the Dn110 specification, the arc radius of described rebound surface r3, transition circle cambered surface r1 and interference surface r2 can be 17mm, 15mm and 4mm successively.In the Dn160 specification, the arc radius of described rebound surface r3, transition circle cambered surface r1 and interference surface r2 can be 24.8mm, 21.5mm and 5.8mm successively.The bar number of described spiral stream guidance muscle can be provided with as required voluntarily, is preferably 11 or 16.Generally 11 can be selected for use, 16 can be selected for use at the Dn160 specification at the Dn110 specification.Because the bar number of the spiral stream guidance muscle of spiral rib number of the present utility model common helical silencing gutter compared to existing technology is many, the Dn110 specification be 11: 6, the Dn160 specification be 16: 8, therefore, the tubing strength-enhanced of same size.
In the utility model, the material of helical silencing gutter adopts low foaming rigid polyvinyl chloride.
But the above only is a preferable possible embodiments of the present utility model, is not in order to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model manuals and accompanying drawing content are done changes, all in like manner to be included in the scope of the present utility model.
