Pipe, industrial pipe, agriculture pipe etc..Which are mainly applied to urban water supply, city gas supply and field irrigations.
After long-term use, inner wall of the pipe is easy generating dirt to these pipelines, or even causes to block.
Summary of the invention
The technical problem to be solved by the present invention is to provide one kind in view of the above technical problems to remove inner wall dirt automatically
The pipeline of dirt.
In order to solve the above technical problems, the technical scheme adopted by the invention is that a kind of automatically cleaning pipeline, including tube body,
The inner wall surface for being characterized in that the tube body is accordion.
Its principle is that existing inner wall of the pipe surface is smooth surface inner wall, since duct wall has certain thickness, because
When the variation of weather keeps pipeline heated or is cooled, it may occur that thermal expansion and contraction, due to inner wall of the pipe smooth surface, and inner circle is partly
Diameter is small, if expansion or shrinkage inwardly, inside can be made to become compact and uniformly be squeezed, naturally the outside tension of generation and
Expansion or shrinkage is set to be obstructed；And the exradius on the outside of pipeline is big, if expansion or shrinkage outward, outside can be made to become dilute
Pine makes expansion or shrinkage become to be more easier；Therefore, it can generally be expanded outward by caused volume change of expanding with heat and contract with cold,
Or from the inward-facing contraction of appearance, and inner surface is difficult to change, even if there is subtle variation, the variation of inner surface is also equal
Even synchronization, the dirt of attachment on an internal surface so still can be firmly attached on the inner surface of pipeline.It will be in pipeline
After surface is designed to accordion, the extruding for being subject to inner surface because expanding with heat and contract with cold can become unevenly, uneven in this way
Accordion inner surface in concave portion can be more raised, and due to having thickness tube body, the variation journey of female parts
Degree can be comparatively small, and in this way since the variation of inner surface is asynchronous, the dirt adhered on an internal surface will appear dislocation, gradually take off
From to realize automatically cleaning.
A kind of structure of its inner surface is：It is stacked that the inner wall surface of the tube body is made into arc turnover from longitudinal direction.Such as Fig. 1
It is shown.
Another structure of its inner surface is：The inner wall surface of the tube body is made into from longitudinal direction directly transfer it is stacked.Such as
Shown in Fig. 2.
Another structure of its inner surface is：The inner wall surface of the tube body is made into cambered surface rugosity from longitudinal direction.Such as
Shown in Fig. 3.
Another structure of its inner surface is：The inner wall surface of the tube body is made into wave rugosity from longitudinal direction.Such as
Shown in Fig. 4.
In order to further ensure that the inner surface of tube body inwardly collapses, tube body can be set as two layers, internal layer is using thermal expansion system
The big material production of number, the outer layer material production small using thermal expansion coefficient, when expanding with heat and contract with cold, makes the side of collapsing of outer layer
Since outer surface, internal layer collapses orientation since inner surface for position；It is attached when inner surface is when collapsing amplitude and reaching a certain level
Dirt on an internal surface will appear dislocation, progressively disengage, to realize automatically cleaning.
Further, tube body can be set as to three layers or multilayer, regard that layer for being close to internal layer as solid layer, internal layer is adopted
With the big material production of thermal expansion coefficient, the material production small using thermal expansion coefficient of solid layer when expanding with heat and contract with cold, makes
Internal layer collapses orientation since inner surface；When inner surface collapse reache a certain level when, adhere to dirt on an internal surface
It will appear dislocation, progressively disengage, to realize automatically cleaning.
Claimed is the pipeline that inner wall of the pipe inner surface is designed to above-mentioned fold-like structures, regardless of should
Whether pipeline is whether to have middle layer, outer layer or more layers except one layer or the inner wall of the pipeline；Also no matter the pipeline is
Which kind of it is made of material；As long as inner wall inner surface is above structure, within the scope of protection of present invention.
After the inner wall inner surface of pipeline is designed to accordion, make pipe because expanding with heat and contract with cold
The extruding that road inner surface is subject to becomes unevenly, and concave portion can be more raised in accordion inner surface rough in this way,
And the variation degree of female parts can be relatively small, it is attached in this way since the variation degree of different parts on inner surface is asynchronous
Dirt on an internal surface will appear dislocation, progressively disengage, so that tube body be made to realize automatically cleaning.
