Abstract
The utility model discloses a kind of recessed ripple bellowss, including external tube layer, interior tube layer and ripple skeleton, the ripple skeleton is helically looped around on the outside of interior tube layer, the ripple skeleton both ends are equipped with interior ripple skeleton, the interior ripple skeleton is arranged between external tube layer and interior tube layer, and interlayer is equipped between the adjacent interior ripple skeleton.The utility model is in use, to prevent interior tube layer pressure-rupturable, stress is offset by interior ripple skeleton, when external tube layer stress, interior ripple skeleton generates deformation, stress is offset to contract by ripple skeleton, pass through the filled layer on the inside of ripple skeleton and interior ripple skeleton and interior filled layer, not only buffer capacity is strong for filled and process material, and cost is low, and in entire loading process, stress suffered by interior tube layer is almost offset by relatively parallel interior ripple skeleton and ripple skeleton, so as to which stress is smaller, so that pipeline entire compression ability is strong, pipeline is not easily broken, prolong the service life.
Description
Technical field
The utility model is related to pipe technology field, more particularly to a kind of recessed ripple bellows.
Background technology
Corrugated pipe is using polyvinyl resin as primary raw material, adds in appropriate amount of addition agent, extruded shaping, application is more and more wider
It is general, gradually apply to building, communication, agricultural.Have many advantages, such as that light-weight, resistance is small, compression strength is high, easy for construction,
It is the ideal material for substituting cast iron pipe and Cement Concrete pipe.Existing bellows integral strength is poor, is squeezed and easily generates rupture,
And it is easily worn after the permanent use of high spot be subject to the external world, greatly reduces service life.Bellows is usually smooth
Inner wall layer and outer profile undulate outer wall layer, due to reasons in structure, the ring stiffness of this kind of bellows is relatively low, and critical external compressive resistance is born
Loading capability is relatively poor, and tubing easily deforms.For this purpose, a kind of it is proposed that recessed ripple bellows.
Utility model content
The main purpose of the utility model is that providing a kind of recessed ripple bellows, asking in background technology can be effectively solved
Topic.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of recessed ripple bellows, including external tube layer, interior tube layer and ripple skeleton, the ripple skeleton is helically looped around interior
On the outside of tube layer, the ripple skeleton both ends are equipped with interior ripple skeleton, and the interior ripple skeleton is arranged on external tube layer and interior tube layer
Between, interlayer is equipped between the adjacent interior ripple skeleton.
Further, the ripple skeleton and interior ripple skeleton section are in arc-shaped.
Further, the interior ripple skeleton depth of section is equal to the half of ripple skeleton depth of section.
Further, filled layer is equipped between the ripple skeleton and interior tube layer.
Further, interior filled layer is equipped between the interior ripple skeleton and interior tube layer.
Further, the filled layer and interior filled layer are foam.
Further, the interior ripple skeleton and ripple skeleton junction section are in arc-shaped.
Compared with prior art, the utility model has the advantages that：In use, for prevent interior tube layer by
It crushes and splits, when ripple skeleton stress generates deformation, can stress be offset by the interior ripple skeleton of both sides, when external tube layer stress
When, interior ripple skeleton generates deformation, stress is offset to contract by ripple skeleton, by ripple skeleton and interior ripple skeleton
The filled layer of side and interior filled layer, not only buffer capacity is strong for filled and process material, but also cost is low, and entire loading process
In, the stress suffered by interior tube layer is almost offset by relatively parallel interior ripple skeleton and ripple skeleton, so as to which stress is smaller, is made
Pipeline entire compression ability it is strong, pipeline is not easily broken, and is prolonged the service life.
Description of the drawings
Fig. 1 is a kind of overall structure diagram of recessed ripple bellows of the utility model.
In figure：1st, interior ripple skeleton；2nd, interior filled layer；3rd, ripple skeleton；4th, filled layer；5th, external tube layer；6th, interlayer；7th, it is interior
Tube layer.
Specific embodiment
Technical means, creative features, achievable purpose and effectiveness to realize the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figure 1, a kind of recessed ripple bellows, including external tube layer 5, interior tube layer 7 and ripple skeleton 3, the ripple skeleton 3
Interior 7 outside of tube layer is helically looped around, 3 both ends of ripple skeleton are equipped with interior ripple skeleton 1, and the interior ripple skeleton 1 is set
It puts between external tube layer 5 and interior tube layer 7, interlayer is equipped between the adjacent interior ripple skeleton 1.
Wherein, the ripple skeleton 3 and interior 1 section of ripple skeleton are in arc-shaped.
Wherein, interior 1 depth of section of ripple skeleton is equal to the half of 3 depth of section of ripple skeleton.
Wherein, filled layer 4 is equipped between the ripple skeleton 3 and interior tube layer 7.
Wherein, interior filled layer 2 is equipped between the interior ripple skeleton 1 and interior tube layer 7.
Wherein, the filled layer 4 and interior filled layer 2 are foam.
Wherein, the interior ripple skeleton 1 and 3 junction section of ripple skeleton are in arc-shaped.
A kind of recessed ripple bellows of the utility model, in use, to prevent interior 7 pressure-rupturable of tube layer, when ripple bone
When 3 stress of frame generates deformation, can stress, when 5 stress of external tube layer, interior ripple skeleton 1 be offset by the interior ripple skeleton 1 of both sides
Deformation is generated, stress is offset to contract by ripple skeleton 3, passes through the filled layer of 1 inside of ripple skeleton 3 and interior ripple skeleton
4 and interior filled layer 2, not only buffer capacity is strong for filled and process material, but also cost is low, and in entire loading process, inner tube
Stress suffered by layer 7 is almost offset by relatively parallel interior ripple skeleton 1 and ripple skeleton 3, so as to which stress is smaller so that pipe
Road entire compression ability is strong, and pipeline is not easily broken, and is prolonged the service life.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made, should all fall into the scope of protection of the utility model.
