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, 2, irrigator of the present invention comprises five major parts: netted filter screen 1, intake chamber 2, boss 3, runner section 4, dentalation 5 and effluent trough 6.Intake chamber 2 communicates with the water inlet of runner section 4, and effluent trough 6 communicates with the delivery port of runner section 4.Netted filter screen 1 is positioned at the bottom of intake chamber 2, that boss 3 is is linear, be evenly distributed on runner section 4 in, dentalation 5 is linearity, is evenly distributed on the both sides of runner section 4, and staggered with the position of boss 3, makes the runner of irrigation pipe present back-shaped labyrinth path.This back-shaped labyrinth path makes flowing water not only in the part swirling flow be arranged, and in the outer character of streaming that has been with of boss 3.
Be that the present invention is described in further detail below with the example.
A kind of example, filter screen 1 is that rectangle is netted, intake chamber 2 and effluent trough 6 are rectangular channel, boss 3 be shaped as rhombus, its interior angle is 30 degree, the number of boss 3 is 8, dentalation 5 for the runner section outer rim is an isosceles triangle, and the between cog angle is 30 degree, and is interlaced with boss 3.
Current flow into from netted filter screen 1 with certain working head, enter after the filtration in the intake chamber 2, and intake chamber 2 is bigger rectangular channels in cross section (with respect to the sectional area of runner), so that current can become in intake chamber 2 is comparatively slow, are difficult for forming rapid whirlpool.Then current enter runner section 4, when current pass through a rhombus boss, current are divided into two, merge into current at the dentalation place, then by next rhombus boss and dentalation, so circulation, make current be rendered as back-shaped mazy current that stream, enter effluent trough 6 at last, effluent trough 6 is identical with intake chamber 2, also is a bigger rectangular channel in cross section.So far, irrigator has been finished whole process from inlet water to outlet water.
Except that this example, the concrete form of filter screen 1 can change, and is rectangular-shaped except what use always, can also be array of orifices etc.Boss 3 concrete shapes, size, number all can change.For example boss can be triangle, rectangle, ellipse etc., and we can also reach the size that changes runner by the size that changes boss, and the number of boss also can change.For the rhombus boss, we can change the size of its angle, and 10 degree～30 degree also can.Dentalation 5 and boss are staggered correspondences, and its form and boss are corresponding.During for the rhombus boss, the angle of the angle of dentalation and rhombus boss is the same big.
As shown in Figure 3, runner section 4 can be provided with double boss 3.
During concrete enforcement,, make the irrigate band with irrigator and light-wall pipe integrated molding (being that front view institute presentation surface is embedded in the light-wall pipe).Be that current enter intake chamber 2 after by netted filter screen 1, by runner section 4 and boss 3 when current feed light-wall pipe with certain head (operating pressure) in, entered effluent trough 6 at last, one aperture is arranged on the light-wall pipe of corresponding effluent trough 6, be used for last water outlet, supply with crops.
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 back-shaped flow passage structure that streams, and has adopted the plane labyrinth flow-path of boss and broached-tooth design here respectively as a kind of example of this invention.Current are at first by netted filter screen, and big solid particle and some phytoplanktons, microorganism have been filtered, and have effectively protected whole runner not blocked, have improved the performance of anti-blockage of irrigator on the whole.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 when the labyrinth flow-path of the zigzag structure that is not more than 30 degree through the crown angle; 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; In addition, during the boss of current by irrigator central authorities, be divided into two shuntings, and when pooling a runner at the dentalation place, washing away mutually between two shuntings has effect of energy dissipation more efficiently.Under the acting in conjunction aspect above-mentioned three, 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 labyrinth type annular is streamed the water flow that the size of the dentalation of runner and boss has determined irrigator.
In sum, this irrigator has creatively been introduced the labyrinth type annular and has been streamed 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.
