Abstract
The invention discloses a kind of novel double flat wall drainpipe, including inner tube, outer tube and reinforcing rib, the axial line of said inner tube is overlapped with the axial line of outer tube, reinforcing rib is arranged between inner tube and outer tube, the cross section of the reinforcing rib is " V " shape, two-phase neighbour reinforcing rib is sequentially connected in circumferential direction, and the reinforcing rib is connected as a single entity with inner tube and outer tube.Present invention design is reasonable, simple in structure, easy to transform, by varying the moulding of reinforcing rib, the ring stiffness of hollow drainpipe can be improved 20% 30%, under equal conditions the wall thickness of hollow drainpipe can be reduced 10% or so, and can be by the cost reduction 10% or so of hollow drainpipe.
Description
Technical field
The present invention relates to a kind of novel double flat wall drainpipe.
Background technology
As the growing tension of land resource, the continuous of city size expand, the collection to rainwater recycles, the row of sewage
The problems such as putting becomes increasingly conspicuous, and the safe handling of drainpipe is also increasingly valued by the people, and various tubing emerge in an endless stream, but all deposit
Such or such the problem of.Although novel double flat wall drainpipe uses more and more extensive, existing novel double flat wall drainpipe
Because the reinforcing rib between its inner and outer pipes is disposed radially, there are the deficiencies of ring stiffness is low, wall thickness is big, of high cost.
The content of the invention
In view of the drawbacks described above of the prior art, the technical problems to be solved by the invention are to provide a kind of new double flat
Wall drainpipe.
Technical scheme is as follows：A kind of novel double flat wall drainpipe, including inner tube, outer tube and reinforcing rib, it is described
The axial line of inner tube is overlapped with the axial line of outer tube, and reinforcing rib is arranged between inner tube and outer tube, it is characterised in that：The reinforcement
The cross section of muscle is " V " shape, and two-phase neighbour's reinforcing rib is sequentially connected in circumferential direction, and the reinforcing rib is linked as one with inner tube and outer tube
Body.
Using above technical scheme, the reinforcing rib between inner tube and outer tube is arranged to " V " type, the reinforcing rib is in inner and outer pipes
Between annular space in it is continuously distributed, and reinforcing rib is connected as a single entity with inner and outer pipes, so effectively increases hollow drainpipe
Ring stiffness, can under equal conditions reduce the wall thickness of hollow drainpipe, and reduce the cost of hollow drainpipe.
The sectional area that two adjacent said ribs and inner tube surround space is equal to the section that reinforcing rib surrounds space with outer tube
Product.Above structural bead is formed with outer tube corresponding part is similar to equilateral triangle, two adjacent said ribs portion corresponding with inner tube
Divide also to be formed and be similar to equilateral triangle, so as to improve the ring stiffness of hollow drainpipe to greatest extent.
Preferably, said inner tube, outer tube and reinforcing rib are made of PVC material.
Preferably, said inner tube, outer tube and reinforcing rib are made of PP materials.
Beneficial effect：Present invention design is reasonable, simple in structure, easy to transform, by varying the moulding of reinforcing rib, can incite somebody to action
The ring stiffness of hollow drainpipe improves 20%-30%, under equal conditions the wall thickness of hollow drainpipe can be reduced 10% or so,
And can be by the cost reduction 10% or so of hollow drainpipe.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 1, the present invention is made of inner tube 1, outer tube 2 and reinforcing rib 3.Wherein, the axial line of inner tube 1 and outer tube 2
Axial line overlap, the surfaces externally and internally of inner tube 1 is smooth, and the surfaces externally and internally of outer tube 2 is also smooth.Reinforcing rib 3 be arranged at inner tube 1 with it is outer
Between pipe 2, the cross section of reinforcing rib 3 is " V " shape, and two-phase neighbour reinforcing rib 3 is sequentially connected in circumferential direction, and reinforcing rib 3 and inner tube 1
And outer tube 2 is connected as a single entity.
Preferably, inner tube 1, outer tube 2 and reinforcing rib 3 can be made of PVC material, can also be made of PP materials.Two
The sectional area that adjacent said rib 3 and inner tube 1 surround space is equal to the sectional area that reinforcing rib 3 surrounds space with outer tube 2, strengthens
The thickness of muscle 3 is equal to the wall thickness of inner and outer pipe, and reinforcing rib 3 is formed with 2 corresponding part of outer tube is similar to equilateral triangle, and two is adjacent
Reinforcing rib 3 is also formed with 1 corresponding part of inner tube is similar to equilateral triangle.
Preferred embodiment of the invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Need creative work to conceive according to the present invention and make many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
