Embedded drip irrigation pipe water dropper
The utility model relates to a kind of embedded drip irrigation pipe water dropper.
At present, in order to economize on water, agricultural planting is carried out water-saving drip irrigation; The water dropper that drip irrigation is used is the main structural components of drip irrigation; Existing pressure compensating emitter comprises the water dropper body, and the diaphragm of water dropper body is provided with lid; Have penetrating hole on the said lid, between the penetrating hole of cover inner surface, have runner; This water dropper manufacturing process is complicated, and the non-compensation douche of its manufacture deviation coefficient ratio is high.
Another kind of external compensation water dropper directly is plugged on the irrigation pipeline; Simultaneously the uniformity that the constant voltage compensating diaphragm drips with raising is set in water dropper, this external compensation water dropper, basic structure comprises that water dropper seat and the labyrinth emitter that is socketed in the water dropper seat constitute water inlet and backwater cavity; The water dropper seat is provided with the plug with the drip irrigation pipe interlocking; Set out the mouth of a river and water return outlet on the water dropper wall, the water dropper below is provided with water dropping openings, establishes the constant voltage compensating diaphragm between water inlet and the backwater cavity; The defective of this water dropper is when compensating coefficient, and the runner under the constant voltage compensating diaphragm is very little, and is blocked easily, and the flow of the douche outflow of flushing during state during with compensating coefficient compared, and increase more is unfavorable to the operation of water pump.
Also have the detachable drip irrigation pipe of a kind of microgravity water dropper, constitute by water delivery hollow billet and corresponding spiral-lock bonnet, water dropper body above that; Reference column, staggered reciprocal runner wall and water dropper body apopore are set on the water dropper body; On water delivery hollow billet tube wall, be provided with the water hole of matching with reference column, on bonnet, be provided with the bonnet fixed lobe that presses the location with the water delivery hollow billet with the fixed connection hole that is fixedly connected the post interference fit; This water dropper production procedure and manufacture craft be relative complex also, and cost is too high.
Summary of the invention
The purpose of the utility model provides that a kind of manufacturing process is simple, flow pressure is stable, the effective embedded drip irrigation pipe water dropper of drip irrigation.
The purpose of the utility model realizes through following technical scheme:
Its characteristics of the utility model are: comprise water dropper body, the water dropper mouth of pipe, water dropper tube chamber, described water dropper is divided into four faces, and the middle part of described first face of drip irrigation is along circumference; The part is provided with several recessed filtration mouths of intaking, and described water inlet is filtered mouth and is communicated with the water dropper tube chamber, with the both sides of same of described water inlet filtration mouth; Be provided with the wave runner along circumference, described wave runner is arranged several along axis, and described water inlet is filtered on mouth and the wave runner one side water dropper body face; Be provided with U type effluent trough along circumference, the U-shaped opening of said U-shaped effluent trough is towards circumference, and described U-shaped effluent trough is arranged to two groups along axis and is several; And U-shaped effluent trough opening is relative, and interleaved is arranged, and described water inlet is filtered on mouth and the wave runner opposite side water dropper body face; Be provided with rectangle along circumference and cross water cavity, described rectangle is crossed water cavity and is several, arranges along axis; On the water dropper body face that described water inlet is filtered mouthful and the wave runner is relative; Be provided with the wave backwater cavity along circumference, described wave backwater cavity is several, arranges along axis.
Compared with prior art, the utility model adopts embedded drip irrigation pipe water dropper, leans on frictional head loss and local head loss's energy dissipating of runner; Channel size does not change with the variation of water pressure, so between whole pressure area, the flow pressure relation is stable; Drip irrigation designer need not consider that optimum pressure is interval, and the wave runner that is designed can make the particulate in the current, with the current fluctuating flow; No current dead angle, current are turbulent condition, in the water outlet uniformity deviation 5%; The water dropper delivery port goes out to adopt " U " type effluent trough, and performance of anti-blockage is excellent, and the fluidised form index is good; The water dropper of this structure is convenient to once injection moulding, is simple, the effective embedded drip irrigation pipe water dropper of a kind of technology manufacturing.

In the diagram, 1 is U type effluent trough, and 2 filter mouthful for water inlet, and 3 is the wave runner, and 4 is the water dropper body, and 5 is the water dropper mouth of pipe, and 6 cross water cavity for rectangle, and 7 is the water dropper tube chamber, and 8 is the wave backwater cavity.
The specific embodiment
Embodiment: with reference to accompanying drawing 1～10, present embodiment comprises water dropper body 4, the water dropper mouth of pipe 5, water dropper tube chamber 7, and described water dropper is divided into four faces; Described water dropper is a circular cylindrical cavity, and the circular cylindrical cavity two ends are provided with the water dropper mouth of pipe 5, the water dropper mouth of pipe 5 outside circular cylindrical cavity, be provided with two the circle protruding stupefied; The middle part of described first face of drip irrigation is along circumference, and the part is provided with six recessed water inlets and filters mouthfuls 2, and described water inlet is filtered mouthfuls 2 and is communicated with water dropper tube chamber 7; Both sides with 2 same in mouth is filtered in described water inlet are provided with wave runner 3 along circumference, and described wave runner 3 is arranged three respectively along axis; On 4 of described water inlet filtration mouth 2 and the wave runner 3 one side water dropper bodys, be provided with U type effluent trough 1 along circumference, " U " shape opening of said " U " shape effluent trough 1 is towards circumference; It is three that described U-shaped effluent trough 1 is arranged to two groups along axis, and U-shaped effluent trough opening is relative, and interleaved is arranged; On 4 of described water inlet filtration mouth 2 and the wave runner 3 opposite side water dropper bodys, be provided with rectangle along circumference and cross water cavity 6, it is four that described rectangle is crossed water cavity 6; Arrange along axis, described water inlet is filtered on 4 of the relative water dropper bodys of 2 mouthfuls and wave runner 3, is provided with wave backwater cavity 8 along circumference; Described wave backwater cavity 8 is eight, arranges along axis.
Said water inlet is filtered a mouth left end and is linked to each other with the wave runner, and current filter a mouthful entering wave runner through water inlet, and the rectangle of flowing through is crossed water cavity top edge runner; Get into wave backwater cavity upper end wave runner; Step-down through the wave runner is handled, and flows out from wave backwater cavity lower end, crosses the backflow of water cavity lower limb runner through rectangle and gets into the wave runner; The final U type effluent trough that flows into flows out from drip irrigation is with holes.
