Description
Technical field
The invention belongs to agricultural water-saving irrigation technical fields, are related to one kind and being related to interior edge patch type douche.
Background technology
Trickle irrigation is a kind of one of internationally recognized efficient water-saving irrigation technology, has apparent uniform, high-efficiency water-saving of pouring water
It saves fertilizer, increasing both production and income, be convenient for the advantages that management, by countries in the world extensive use.Douche is the core component of drip irrigation technique, is filled
Hydrophone designs quality, the service life of management cost and drip irrigation system for whether rationally determining trickle irrigation, and key technology is to make pressure
Power flow makes waterflow stabilization, uniformly instills soil by internal runner energy dissipating.The factors such as the structure and size of runner determine
It goes out to flow the hydraulic performances such as stability, anti-stifled ability.The construction of existing drip emitter runner is with various tooth form knots mostly
Based on the runner of configuration formula, structure type, the specification etc. of domestic and international existing runner are improved, base is then developed
In the drip emitter of flow path of gear profile.There is easily blocking and unevenness of dripping caused by energy dissipating deficiency in flow path of gear profile douche runner
Even problem.
Therefore, it becomes increasingly conspicuous under the new situation, is developed with height in current international and domestic grain security, water resource contradiction
The drip emitter of energy dissipating anti-clogging is significant to the development of drip irrigation technique.
Invention content
The invention reside in the existing trickle irrigations of solution easily to block and drip non-uniform technical problem, and trickle irrigation can be made by providing
Water turbulence degree enhancing in douche runner, flow channels increase, anti-stifled ability enhancing, uniform a kind of interior edge patch of dripping
Chip douche drip emitter.
To achieve the goals above, the technical solution that the present invention takes is that edge patch type douche includes in one kind
Narrow slit comb shape filters window construction water inlet（1）With runner（2）It communicates, the runner other end is connected to water outlet（5）.Runner master in douche
It will be by four sides scapus（3）And triangular prism（4）It is interspersed and constitutes netted runner；Netted runner be divided into before in after three parts, respectively
For module I, module ii and module ii I.
Module I is by triangular prism in netted runner（4）Around four sides scapus（3）Row composition, triangular prism towards four sides scapus and
Triangular prism（4）With adjacent four sides scapus（3）It is interspersed；Module I and water inlet in netted runner（1）It is connected.
The module ii of netted runner by repeat grid cell form, each grid cell include before in after three parts.Net
The front end of lattice unit is four sides scapus（3）With towards four sides scapus（3）Triangular prism（4）The sudden expansion structure of composition, middle part four
Face scapus（3）With towards four sides scapus（3）Triangular prism（4）The netted multiple flow passages of the staggered composition of row of composition, rear end is
Towards the triangular prism of front end（4）The sudden contraction structure of composition.
Netted flow-path module III and water outlet（5）It is connected；Module ii I includes the four sides scapus of front end（3）With direction four
Face scapus（3）Triangular prism（4）The sudden expansion structure of composition, four sides scapus（3）With towards four sides scapus（3）Triangular prism（4）Group
At the staggered composition of row netted multiple flow passages and towards the triangular prism of front end（4）The sudden contraction structure of composition.
Beneficial effects of the present invention
Interior edge patch type douche provided by the invention, simple in structure, easy to process and production cost are low.The net of the present invention
Shape runner douche by fluid, different intersections of branch form impact and setting runner longitudinal direction section and have inside runner
It periodic sudden enlargement and reduces and energy dissipating suddenly；Flow and boundary separation and the circulation generated, circulation can drive silt
Equal substances alleviate blockage problem, meanwhile, ring current shock flow path boundary increases head loss, has efficient effect of energy dissipation, has
Conducive to the flow stance index of douche is reduced, drip more uniformly.
Description of the drawings
Fig. 1 is douche structural schematic diagram
In figure：1- water inlets；2- runners；The four sides 3- cylinder；Tri- face cylinders of 4-；5- is discharged.
Specific implementation mode
As shown in Figure 1, for a kind of interior edge patch type douche of the present invention, including narrow slit comb shape filters window construction water inlet（1）
With runner（2）It communicates, the runner other end is connected to water outlet（5）.Runner is mainly by four sides scapus in douche（3）And triangular prism
（4）It is interspersed and constitutes netted runner；Netted runner be divided into before in after three parts, respectively module I, module ii and module ii I.
Module I is by triangular prism in netted runner（4）Around four sides scapus（3）Row composition, triangular prism towards four sides scapus and
Triangular prism（4）With adjacent four sides scapus（3）It is interspersed；Module I and water inlet in netted runner（1）It is connected.
The module ii of netted runner by repeat grid cell form, each grid cell include before in after three parts.Net
The front end of lattice unit is four sides scapus（3）With towards four sides scapus（3）Triangular prism（4）The sudden expansion structure of composition, middle part four
Face scapus（3）With towards four sides scapus（3）Triangular prism（4）The netted multiple flow passages of the staggered composition of row of composition, rear end is
Towards the triangular prism of front end（4）The sudden contraction structure of composition.
Netted flow-path module III and water outlet（5）It is connected；Module ii I includes the four sides scapus of front end（3）With direction four
Face scapus（3）Triangular prism（4）The sudden expansion structure of composition, four sides scapus（3）With towards four sides scapus（3）Triangular prism（4）Group
At the staggered composition of row netted multiple flow passages and towards the triangular prism of front end（4）The sudden contraction structure of composition.
Drip emitter runner is interconnected by several runners, forms netted runner, netted runner be include several three faces
Cylinder and four sides cylinder, flow enter from the water inlet of multiple runners, and multiple water inlets can alleviate blockage problem, when flowing through the
One row, three face cylinder, fluid form impact in the tail end runner intersection of three face cylinders, achieve the purpose that energy expenditure；Flow exists
After impacting, shunt again, bypass four sides cylinder, then further around cross three face cylinder of secondary series after, flow expands suddenly
Greatly, too urgent variation occurs for boundary layer flow, and boundary layer flow is promoted to be detached with boundary, forms burble point.In burble point hereinafter, water
Stream is detached from boundary, forms the stream band of just left unattached.The side for flowing band is positive stream, and the other side is circulation around circuit.Circulation not only can be with
The substances such as silt are driven, blockage problem is alleviated, meanwhile, ring current shock flow path boundary increases head loss, has efficient energy dissipating
Effect advantageously reduces the flow stance index of douche, drips more uniformly.
Flow is after sudden enlargement, when by secondary series four sides cylinder, and passes through the flow channels reduced suddenly, from
This starts the energy dissipation of another wheel, and cycle is gone down successively, is finally reached the purpose uniformly poured water.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
The right present invention has been described by way of example and in terms of the preferred embodiments, however, it is not limited to the present invention, any technology people for being familiar with this profession
