Description
Technical field
The utility model belongs to the drip irrigation technique field in the agriculture and forestry irrigation, is specifically related to a kind of bidirectional flow water dropper.
Background technology
Drip irrigation is a kind of advanced person's an agricultural water-saving irrigation technology, is widely used in trees and industrial crops and irrigates.Water dropper is one of critical piece of drip irrigation, and the function of water dropper is to eliminate the excess energy of drip irrigation pipe pressure flow, and assurance water is irrigated crop root uniformly and stably.
The water dropper that uses both at home and abroad at present can be divided into two types, promptly turbulent labyrinth emitter and pressure compensating emitter according to the energy dissipating mode of its runner.Publication number be the patent text of CN201199834, CN201632346 and CN201192667 disclosed all be turbulent labyrinth emitter; Its operation principle is: when the runner of pressure water stream through a bending; Form turbulent flow, produce vortex, can produce bigger local head loss.In order to eliminate unnecessary pressure, in water dropper, a series of curved channels are joined end to end, form turbulent labyrinth path; The water dropper fluidised form index of this type is between 0.5～0.7, and when the water dropper change of pressure, the water dropper outflow changes less; Its manufacturing cost is lower, and service life is longer, but because the runner cross dimensions is very little; Its anti-clogging is relatively poor, because runner is longer, the accuracy of manufacture is also wayward in addition.Publication number be the patent text of CN2648806, CN201446021 and CN200987311 disclosed all be pressure compensating emitter; Its operation principle is: when the compensation water dropper of pressure water circulation excess pressure, on the flexible sheet of effect of water pressure in water dropper, hydraulic pressure is different; The flexible sheet distortion is different; With this size of regulating the runner cross-section of river, reach the purpose of energy dissipating decompression, the water dropper fluidised form index of this type is about 0.1; When the water dropper change of pressure was big, the water dropper outflow changed very little; But because the inner flexible diaphragm device of runner, its production cost is higher, and in the open-air rugged environment in farmland, flexible sheet is prone to aging, has influence on its service life, because the runner section is very little, runner is easy blocking also simultaneously.
The utility model content
The purpose of the utility model provides a kind of bidirectional flow water dropper, simple structure, and outflow is stable, and anti-clogging is strong, and production cost is low, long service life.
The technical scheme that the utility model adopted is that a kind of bidirectional flow water dropper is characterized in that; Comprise hollow housing; Housing bottom has a plurality of delivery ports to being arranged with water inlet on the sidewall of housing, in the housing and the below that is positioned at a plurality of delivery ports is provided with water deflector and divides water spare; Water deflector is positioned at the top of branch water spare
Water deflector is a V font plate; Divide water spare by becoming splayed symmetry and two branch water plates spaced apart to form; Form water hole between two branch water plates; Divide the dehiscing all towards the bottom of housing of water spare and water deflector, water deflector is fixed on front and back two inwalls of housing with the rear and front end correspondence of dividing water spare, and two inwalls all left aquaporin about the limit wing of water deflector and branch water spare and housing.
Housing, water inlet, water deflector and branch water spare are coaxial setting.
Water deflector is 40 °～120 ° with the subtended angle scope of dividing water spare.
Water inlet is a pan head shape.
The quantity of delivery port is two, and is symmetrically distributed on two relative sidewalls.
The water inlet aperture diameter is 1.5～3mm, and each delivery port aperture diameter is 1-2mm; The width of crossing aquaporin is 0.5～1.2mm, and the width of water hole is 0.5～1.0mm.
The beneficial effect of the utility model is: through the strong blending of the positive and negative both direction current that in the housing of bidirectional flow water dropper, form, eliminate the excess energy of pressure water stream on the one hand, also make it have stronger anti-blocking on the one hand in addition.And the pressure of current is big more, and forward and reverse current blending is strong more, and the energy of eliminating pressure water stream is many more.Therefore, the utility model is compared with existing turbulent labyrinth emitter, has the advantage even, that anti-blocking is strong of effluenting, because runner is short, can reduce production costs again, improves the accuracy of manufacture.The utility model is compared with existing pressure compensating emitter, has simple in structurely, is convenient to install, and production cost is low, the advantage of long service life.

The specific embodiment
As depicted in figs. 1 and 2, a kind of bidirectional flow water dropper comprises the housing 2 of hollow rectangular structure, and housing 2 bottoms are to being arranged with water inlet 1, and water inlet 1 is a pan head shape.Have two delivery ports 3 on the sidewall of housing 2, these two delivery ports 3 are symmetrically distributed on two relative in the housing 2 sidewalls.
In the housing 2 and below that is positioned at two delivery ports 3 is provided with water deflector 5 and divides water spare 4, and water deflector 5 is positioned at the top of branch water spare 4, housing 2, water inlet 1, water deflector 5 and to divide water spare 4 be coaxial setting.Water deflector 5 is a V font plate.Divide water spare 4 by becoming splayed symmetry and two branch water plates spaced apart to form, form water hole between these two branch water plates.Divide the dehiscing all towards the bottom of housing 2 of water spare 4 and water deflector 5, water deflector 5 is fixed on front and back two inwalls of housing 2 with the rear and front end correspondence of dividing water spare 4, and two inwalls all left aquaporin about the limit wing of water deflector 5 and branch water spare 4 and housing 2.
Water deflector 5 is 40 °～120 ° with the subtended angle scope of dividing water spare 4.Water inlet 1 aperture diameter is 1.5～3mm, and each delivery port 3 aperture diameter is 1-2mm; The width of crossing aquaporin is 0.5～1.2mm, and the width of water hole is 0.5～1.0mm.
The utility model operating pressure is 0.1～0.4MPa, and flow is 4～6L/h, and the fluidised form index is between 0.3～0.4.
The operation principle of the utility model is: at first, the pressure water stream in the drip irrigation system hollow billet gets into housing 2 inner chambers through water inlet 1, divides water spare 4 that current are shunted; Wherein, One pressure water stream between two branch water plates because the cross-section of river shrinks gradually, is eliminated portion of energy in flow process; Thereafter this strand current are eliminated portion of energy once more through the water hole between two branch water plates the time; Then under the barrier effect of water deflector 5, this strand current change the flow direction, form two strands of reverse flows that flow along water deflector 5 inwalls; Meanwhile; Two strands of forward current through crossing aquaporin between minute water spare 4 dual-side wings and housing 2 inwalls and above-mentioned two strands of reverse flows meet and converge; Through strong blending, eliminate pressure water stream excess energy, two strands of current after the blending are through crossing aquaporin between the water deflector 5 dual-side wings and housing 2 inwalls; Through spreading further energy dissipating, flow out through delivery port 3 at last.Because forward and reverse current blending is strong in the runner that minute water spare 4 and water deflector 5 form, and has also reduced the possibility that solid granulates deposits simultaneously in runner, has just improved the anti-clogging of the utility model.
The utility model at first punches on the hollow billet of drip irrigation system in use, is installed in this hollow billet through water inlet 1, is used for trees and industrial crops and irrigates.Owing to reasons such as the landform or the loss of flood peakes, in the pipe network of drip irrigation system, pipe network pressure gap everywhere is very big, adopts the utility model bidirectional flow water dropper, can eliminate unnecessary water flow pressure.
