Description
Technical field
The present invention relates to the field of irrigation, more particularly to hangnail type labyrinth flow-path douche.
Background technology
Drip irrigation is a kind of current Water Saving Irrigation Mode maximally effective in the world, is developing modern agriculture, efficient, economizing type agriculture
The optimal irrigation method of industry.Douche is the most key part of whole drip irrigation project, and the quality of its performance is greatly determined
The irrigation quality of integrated engineering benefit, particularly in the case where filter plant is not enough improved and water quality is poor, runner is blocked
Situation is even more serious, and it is blocked mainly as caused by the chemical substance in liquid manure liquid, microorganism emplastic and impurity.Pass through
Increase runner cross dimensions, improve the coefficient of uniformity of water outlet, strengthen runner anti-blockage capability, it is ensured that douche is in certain pressure bar
The service behaviour having had under part is the study hotspot of current drip irrigation expert.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of that there is good water consumption to dissipate effect, water outlet is uniform, no
Susceptible to plugging hangnail type labyrinth flow-path douche.
To solve the above problems, hangnail type labyrinth flow-path douche of the present invention, including provided with water inlet and water outlet
The labyrinth flow-path of mouth, it is characterised in that：The labyrinth flow-path includes two some identical flow passage units of row being cascaded, its
In each flow passage unit the upside hangnail of staggered relative and downside hangnail composition that are set by inverse water (flow) direction；The downside
Hangnail is arranged between two upside hangnails；Each upside hangnail or the downside hangnail are equipped with to be arranged on and met water
The arc section of side and the straightway for being arranged on land side.
Each described flow passage unit overall length is 2.1mm.
The width of each upside hangnail or the downside hangnail is 0.5mm, and is with the angle for the side straight line that meets water
45°~65°。
The length of the straightway is 1.63mm.
The spacing of the upside hangnail and the downside hangnail is 1.56 ~ 1.92mm.
The spacing between spacing or two downside hangnails between unilateral two adjacent upside hangnails is
3.42~3.78mm。
The arc section radius is 0.05 ~ 0.65mm.
The water inlet is grid type water inlet.
The present invention has advantages below compared with prior art：
1st, the present invention is according to the hangnail phenomenon design on plant haulm, and the douche runner is by the relative staggered barbs type knot of two row
Structure is constituted, and the drift angle of each column hangnail type structure is all inverse water (flow) direction, arc section, backwater of each barb structure by the side that meets water
The straightway composition of side, and adjacent barb structure keeps certain spacing, utilizes the hangnail type knot for being partial to import direction
Structure makes current produce strong bending collision and be vortexed the dissipation effects of current, and the detour flow that barb structure is produced
Effect, energy consumption effect is obvious.
2nd, the minimum cross section size range of flow passage structure of the invention is 0.55 ~ 0.65mm2, its flow stance index scope is
0.474~0.508；It is minimum with flow stance index when the angle of hangnail and the side straight line that meets water is 45 ° and arc radius is 0.65
Value, performance of anti-blockage is also optimal.

Embodiment
As shown in Figure 1 and 2, hangnail type labyrinth flow-path douche, including the labyrinth flow-path 3 provided with water inlet 2 and delivery port 1.
Labyrinth flow-path 3 includes two some identical flow passage units of row being cascaded, and each of which flow passage unit by flowing against the current
The upside hangnail 5 and downside hangnail 4 for the staggered relative that direction is set are constituted；Downside hangnail 4 be arranged on two upside hangnails 5 it
Between；Each upside hangnail 5 or downside hangnail 4 are equipped with the arc section 6 for being arranged on the side that meets water and the straightway for being arranged on land side
7。
Wherein：Each flow passage unit overall length is 2.1mm.
The width of each upside hangnail 5 or downside hangnail 4 is 0.5mm, and with the angle of the side straight line that meets water be 45 ° ~
65°。
The length of straightway 7 is 1.63mm.
The spacing of upside hangnail 5 and downside hangnail 4 is 1.56 ~ 1.92mm.
The spacing between spacing or two downside hangnails 4 between unilateral two adjacent upside hangnails 5 is 3.42 ~
3.78mm。
The radius of arc section 6 is 0.05 ~ 0.65mm.
Water inlet 2 is grid type water inlet.
The hydraulic performance simulation of hangnail type labyrinth flow-path douche of the present invention has been carried out in CFD analysis softwares FLUENT
（Referring to Fig. 3）, the flow of douche at various pressures has been obtained, and pressure-flow relationships curve is fitted, its relational expression is, flow stance index is 0.474, and hydraulic performance is good.Pressure increases and reduced with unit number, flow passage unit
Energy dissipating effect is obvious.
Observe the current trace diagram and speed vector figure of runner intermediate cross-section（Referring to Fig. 4 and Fig. 5）, utilize hangnail type structure
To the dissipation effect of current, and the detour flow that barb structure is produced, the strong bending collision of current generation and vortex effect,
Flow turbulence energy consumption effect is obvious.Whole runner continuous uniform is substantially without dead angle area, and unique low regime is vortex area, the vortex
Area is that its position of dynamic area is continually changing with turbulent water, will not produce deposition, therefore the douche is used in a long time
It is not easily blocked.
