Abstract
The utility model discloses a kind of large flow velocity pipeline, comprising: interior pipe, outer tube, support, notch and inner side coating, inside described interior pipe, be provided with inner side coating, interior pipe is outside equipped with support, interior pipe surrounding is provided with notch, and described outer tube sleeve is connected on outside interior pipe, and coaxially arranged with interior pipe.By the way, the utility model large pitot tube road has the advantages such as unfailing performance is high, compact structure, flow resistance are little, flow velocity is high, easy to use, the life-span is long, has market prospects widely at pipeline market simultaneously.
Description
Technical field
The utility model relates to pipeline field, particularly relates to a kind of large flow velocity pipeline.
Background technique
Pipeline is the device of fluid for carrying gas, liquid or band solid particle be connected into pipe, pipe coupling and valve etc., because pipeline exists the impact of bending and pipe surface viscous resistance, make flow rate of liquid in pipeline receive a definite limitation, and cause the larger pressure loss.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of large flow velocity pipeline, by arranging double-skin duct and arranging notch, ensures the flow rate of liquid in central tube, solves pipeline pressure in prior art and changes greatly, the problem that flow velocity is limited.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of large flow velocity pipeline, comprise: interior pipe, outer tube, support, notch and inner side coating, inner side coating is provided with inside described interior pipe, interior pipe is outside equipped with support, interior pipe surrounding is provided with notch, and described outer tube sleeve is connected on outside interior pipe, and coaxially arranged with interior pipe.
In the utility model preferred embodiment, described support is annular, is provided with streamlined strut in the middle of support.
In the utility model preferred embodiment, described notch is provided with multiple, and become interrupted helical to arrange on inner pipe, center line and the interior tubular axis heart of notch section are angled, and notch side opening in interior pipe is arc.
In the utility model preferred embodiment, described inner side coating is lower resistance coating.
The beneficial effects of the utility model are: the large flow velocity pipeline of the utility model, by arranging double-skin duct, makes the liquid in central tube keep larger flow velocity; By arranging the notch of distinctive appearance, effectively reduce tube wall to the impact of current; There is the advantages such as unfailing performance is high, compact structure, flow resistance are little, flow velocity is high, easy to use, the life-span is long, have market prospects widely at pipeline market simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of large flow velocity pipeline one of the present utility model preferred embodiment;
Fig. 2 is the notch enlarged diagram of Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, outer tube, and 2, interior pipe, 3, support, 4, notch.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model is embodiment comprise:
A kind of large flow velocity pipeline, comprising: interior pipe 2, outer tube 1, support 3, notch 4 and inner side coating, is provided with inner side coating inside described interior pipe 2, interior pipe 2 is outside equipped with support 3, interior pipe 2 surrounding is provided with notch 4, and described outer tube 1 is socketed in outside interior pipe 2, and coaxially arranged with interior pipe 2.
Described support 3 is annular, and be provided with streamlined strut in the middle of support 3, effective supporting pipeline also makes water by outer layer pipe.
Described notch 4 is provided with multiple, interrupted helical is become to be arranged on interior pipe 2, center line and interior pipe 2 axle center of notch 4 section are angled, notch 4 side opening in interior pipe 2 is arc, make to flow in the current direction of outside and reduce tube wall to water currents to accelerate flow rate of water flow.
Described inner side coating is lower resistance coating, effectively reduces viscous.
The beneficial effect of the large flow velocity pipeline of the utility model is:
One, by arranging double-skin duct, the liquid in central tube is made to keep larger flow velocity;
Two, by arranging the notch of distinctive appearance, tube wall is effectively reduced on the impact of current;
Three, there is the advantages such as unfailing performance is high, compact structure, flow resistance are little, flow velocity is high, easy to use, the life-span is long, have market prospects widely at pipeline market simultaneously.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
