Abstract
The utility model relates to the technical field of paster-inlaid type droplet irrigators used for saving water in agriculture, in particular to a small-flow full-turbulent-flow drop irrigation emitter. The small-flow full-turbulent-flow drop irrigation emitter comprises a shell, filter windows, a passageway and a pouching groove, wherein the filter windows capable of communicating the interior of the shell with the exterior of the shell are arranged on the shell, the passageway and the punching groove are arranged in the shell, the filter windows and the passageway are communicated, an outlet of the passageway is communicated with the punching grooved, the passageway in a form of a labyrinth, outer sides of the passageway are dentate, each of included angles between teeth and teeth roots ranges from 40 to 60 degrees. The small-flow full-turbulent-flow drop irrigation emitter is reasonable and compact in structure and convenient to utilize, and by utilizing the energy dissipating labyrinth type turbulent-flow passageway with 50-degree angle, the small-flow full-turbulent-flow drop irrigation emitter has the advantages of good turbulent property, small and uniform water flow and good anti-blocking performance, and produced dropper belts are small in diameter and low in cost.
Description
Technical field
the utility model relates to agricultural water-saving and uses the drip irrigation appliance technical field, is the complete turbulent drip emitter of a kind of low discharge.
Background technology
are present; Domestic known douche mainly is to be made up of runner, filtering window, punching district and water irrigating hole, after the filtering window filtration of the press water of treated mistake through douche, gets in the runner of douche; After the damping action energy dissipating through runner, flow out from water irrigating hole; But present douche width dimensions is bigger, and runner is short, and turbulent flow property is poor, the flowing water lack of homogeneity, and runner is narrow, and the anti-property stopped up is poor.
Summary of the invention
the utility model provides a kind of low discharge complete turbulent drip emitter; Overcome the deficiency of above-mentioned prior art, it is bigger that it can effectively solve present douche width dimensions, and turbulent flow property is poor; The flowing water lack of homogeneity, the problem of the deficiency of the anti-property stopped up difference.
The technical scheme of
the utility model realizes through following measure: the complete turbulent drip emitter of a kind of low discharge comprises housing, filtering window, runner and punching groove; The filtering window that can enclosure interior be communicated with outside is arranged on housing; Runner and punching groove are arranged in the inside of housing; Filtering window is connected with the import of runner, and the outlet of runner is connected with the punching groove, and runner is labyrinth type; The outside of runner is dentation, and the teeth of runner and the angle between the tooth root are that 40 degree are to 60 degree.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
Teeth of
above-mentioned runner and the angle between the tooth root can be 50 degree.
above-mentioned housing can be curved.
the utility model reasonable and compact in structure; Easy to use, this douche adopts unique 50 degree angle energy dissipating labyrinth types turbulent flow runner design, has disorderly good fluidity, water yield is little and advantage even, that performance of anti-blockage is good; And the dropper band diameter of processing is less, and cost is lower.
Description of drawings

The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of forward and backward, upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
like accompanying drawing 1,2,3,4, shown in 5, the complete turbulent drip emitter of this low discharge comprises housing 1, filtering window 2, runner 3 and punching groove 4; On housing 1, having can be with the filtering window 2 of housing 1 inside with housing 1 external communications; Runner 3 and punching groove 4 are arranged in the inside of housing 1; Filtering window 2 is connected with the import of runner 3, and the outlet of runner 3 is connected with punching groove 4, and runner 3 is labyrinth type; The outside of runner 3 is dentation, and the teeth of runner 3 and the angle between the tooth root are that 40 degree are to 60 degree.
Can according to actual needs the complete turbulent drip emitter of above-mentioned low discharge be done further to optimize or/and improve:
are shown in accompanying drawing 1; As required; The teeth of runner 3 and the angle the best between the tooth root are 50 degree; Can play best damping action and carry out energy dissipating, when current process runner 3, can produce stirring, can avoid tiny foreign material in runner 3, to deposit like this and cause runner 3 to stop up.
like accompanying drawing 1,2,3,4, shown in 5, housing 1 is curved.Housing 1 can be arc, also can be other shapes, when housing 1 helps the installation and the use of the complete turbulent drip emitter of low discharge during for arc.
above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The use of
the utility model most preferred embodiment: 4 places stamp water irrigating hole at the punching groove, at first pass through the filtration of tiny filtering window 2 in the time of in water gets into runner 3, and filtering window 2 can fall by the contaminant filter that some are big; Water after filtering gets in the runner 3, and the outside of runner 3 is dentation, makes whole runner 3 just as the labyrinth; The teeth of runner 3 and the angle between the tooth root are 50 degree; Can produce stirring when making current, can avoid tiny foreign material in runner 3, to deposit like this and cause runner 3 to stop up through runner 3, and; After the water in the runner 3 is passing through the damping action energy dissipating of runner 3; Pressure and speed reduce gradually, and the speed of current is zero when making current arrive the water irrigating hole place, evenly ooze to drip shape.
