Abstract
An annular turble irrigator is composed of a water inlet trough with mesh filter, an annular water outlet trough with the cross-section greater than that of water inlet through, and a round-trip flow channel consisting of linked to multi-dog-leg channels. Its advantages are not blocking and low cost.
Description
Technical field
The present invention relates to a kind of Water saving type watering arrangement, be specifically related to a kind of ring type flow-disturbing irrigator.
Background technology
Water-saving irrigation is the major measure that the countries in the world developing modern agriculture is taked, and slight irrigation is as the high standard irrigation technique of a kind of advanced person in the water-saving irrigation, by more than 100 country's employing in the world.The wherein tool water saving of drip irrigation, volume increase, significant advantage such as efficient can be widely used in the economic crops plantations such as fruit tree, vegetables, flowers, medicinal material.
Drip irrigation emitter is the parts of most critical in the drip irrigation system, and the quality of the structure of drip irrigation emitter and water conservancy performance thereof is very big to uniformity, anti-blockage capability, the lifetime of system influence of drip irrigation system.The hydraulic performance of drip irrigation emitter determines jointly that by factors such as the form of runner, size, materials 90% of the loss of flood peak all occurs in the circuitous configuration place of irrigator runner.China has introduced the seventies in 20th century from Mexico since the drip irrigation technique, in the independent development nineties some products, but all exist weak point at aspects such as performance of anti-blockage and hydraulic performance and manufacturing process.After the nineties, on the basis of introducing drip irrigation emitter, some drip irrigation emitters have been developed, but the version of drip irrigation emitter, specification substantially all are to copy external product, and too narrow and small circuitous runner is very easily blocked, has seriously influenced the service life of drip irrigation emitter.
Summary of the invention
Main purpose of the present invention is to overcome the existing susceptible to plugging shortcoming of irrigator, and a kind of ring type flow-disturbing irrigator is provided.These irrigator materials are few, cost is low, have the high water outlet uniformity and stronger performance of anti-blockage.
A kind of ring type flow-disturbing irrigator provided by the invention, comprising: intake chamber, runner section and effluent trough is characterized in that: intake chamber and effluent trough be separately positioned on runner section into and out of the water end (W.E.) place, netted filter screen is positioned at intake chamber water inlet end face; Effluent trough is a cannelure, and its area of section is greater than the area of section of intake chamber; Runner section is the annular channel that broken line shape runner is formed by connecting, and wherein, broken line shape runner is made of the triangle zigzag unit that is evenly distributed on both sides, and its triangle interior angle is 10 degree-60 degree.
Above-mentioned broken line shape runner shape in the shape of a spiral connects, or connects by straight shape runner.
Among the present invention, the creationary zigzag flow-disturbing flow passage structure of ring type triangle that adopted of irrigator runner section.The water inlet end face is regularly arranged network structure, and its diameter dimension is less with respect to runner, current is filtered, thereby protected runner, and we claim that it is a filter screen; The runner section space of irrigator is ring type, and the plane is the triangle zigzag, and continuous triangle zigzag structure and the effect of washing away mutually between the current make that the local energy dissipating of this runner is more outstanding, have guaranteed that irrigator has effect of energy dissipation more efficiently.The present invention can be widely used in being used for cotton, sugarcane and vegetables, as the irrigation of tomato, strawberry etc.

Embodiment
Below in conjunction with accompanying drawing and example concrete working method of the present invention is done further detailed elaboration:
The present invention requires irrigator in certain working head (pressure) scope, obtains stable water flow.As shown in Figure 1, irrigator of the present invention comprises four major parts: filter screen 1, intake chamber 2, runner section 3 and effluent trough 4.Intake chamber 2 and effluent trough 4 be separately positioned on runner section 3 into and out of the water end (W.E.) place, netted filter screen 1 is positioned at intake chamber 2 water inlet end faces.Effluent trough 4 is a cannelure, and its area of section is greater than the area of section of intake chamber 2.The both sides of runner section 3 are evenly distributed with triangle sawtooth unit, form broken line shape runner, make that the current in the runner section 3 not only have swirling flow in the part, and macroscopic view have had the character of flow-disturbing.Water side in runner section 3 links to each other with effluent trough 4.
Broken line shape runner shape in the shape of a spiral is distributed in the irrigator middle body, forms ring type flow-disturbing runner; Also can connect arbitrarily, form ring type flow-disturbing runner by some broken line shape runners.
The angle and the length of side of triangle zigzag unit can change, and leg-of-mutton interior angle is 10 degree-60 degree, by changing the size that the leg-of-mutton length of side can change broken line shape runner.We can also change the structure of runner by the number that changes triangle zigzag unit, thereby reach the purpose of the overall performance of optimizing irrigator.
Current flow into from netted filter screen 1 with certain working head, filter the back sluggish flow and enter in the intake chamber 2, are difficult for forming rapid vortex.Then current enter runner section 3, when current pass through a triangle zigzag unit, current bump irrigator runner edge, merge into vortex, by next triangle zigzag unit, current passing through of circulating like this enters effluent trough 4 in all triangle zigzag unit then, effluent trough 4 is different with intake chamber 2, is a cannelure that area of section is relatively large.So far, irrigator has been finished whole process from inlet water to outlet water.
More than set forth the design feature and the course of work of irrigator, below the operation principle of main explanation irrigator.The main feature of this irrigator is to have introduced the broken line shape flow passage structure of triangle jagged edge, has adopted the annular channel of triangle zigzag structure here as a kind of example of this invention.At first by netted filter screen, the size of this filter screen is less with respect to runner, has effectively protected whole runner not blocked, has improved the performance of anti-blockage of irrigator on the whole for current.In current flowed into intake chamber, the speed of current can slow down relatively, has avoided forming the possibility of rapid whirlpool, and current are gone into the runner part with velocity flow relatively stably.Current overcome the effect of frictional resistance on the one hand through broken line shape runner the time; On the other hand, because the corner of runner is anxious, many and continuously, form local eddy currents easily, these eddy current also have the effect of energy dissipating.Under the acting in conjunction aspect above-mentioned two, make the energy of current in short distance, to obtain bigger consumption, realized the energy dissipating of irrigator and the adjusting of pressure.Flow-shape in this runner is full turbulent flow, and its fluidised form index is about 0.5, is no more than 0.57.And the teeth groove structure of annular triangle sawtooth shape flow passage and size have determined the water flow of irrigator.
In sum, this irrigator has creatively been introduced ring type triangle zigzag flow-disturbing runner, provides effect of energy dissipation more efficiently when irrigator easily stops up a difficult problem solving effectively; In addition, irrigator has also adopted and the online integrated molding of pipeline, has reduced cost, and the little materials of volume are economized, and is easy to the field and arranges and collect, and has really accomplished low input, high yield.
