Abstract

A double channel anti-blocking self cleaning pressure compensation emitter, which comprises a dropping pipe, a pressure adjustment elastic film sheet and a dropping cover, the circumference of the dropping pipe is distributed with maze channels with parallel arrangement, and maze channels with annular arrangement arranged in an open manner below the elastic film sheet inside the pressure adjustment area of the dropping pipe and connected with the parallel maze channels. The utility model arranges the annular maze channels below the elastic film sheet, controls the water flow amount inside the maze channel under different pressures through the change of the cooperating size of the elastic film sheet of the pressure adjustment area of the emitter and the below annular anti-blocking maze channels, which makes the exit flux of the pressure compensation emitter stay constant, the maze channels remove the flowing stop area in the channels, and the anti-blocking performance is excellent. The water entering the emitter during work has tiny impurities, which can concentrate below the elastic film sheet to reduce the flux and the pressure of the pressure adjustment area, the film sheet floats, the water passing cross section of the channels increases, the impurities can be discharged into the exit of the emitter and flow out with the water flow.

Description

The anti-stifled self-cleaning pressure compensation douche of dual channel
One, technical field
The utility model belongs to the irrigation field, particularly a kind of anti-stifled self-cleaning pressure compensation douche of dual channel that is used for agricultural water-saving irrigation.
Two, background technology
In the employed various irrigators, plain edition is to regulate the water yield of irrigator by pressure of supply water at present, and the pressure-compensated irrigator then is under different inlet pressures, guarantees that water yield is even substantially.The existing pressure-compensated irrigator one group of labyrinth flow-path that only on circumference, distributed basically, enter the press water of irrigator by irrigator inlet grid, at first flow into the labyrinth runner of on circumference, arranging, after this carries out preliminary energy dissipating, enter the pressure compensation regulatory region, carry out pressure regulation by flexible sheet hydraulic pressure up and down, the flow of pressure compensation douche can only be kept relative stability within the specific limits.And the circular arc labyrinth flow-path that it adopts, there is the stagnation region that flows in fluid when liquid flows through, and irrigator is easily stopped up.
Three, summary of the invention
The purpose of this utility model is to provide a kind of anti-stifled self-cleaning pressure compensation douche of dual channel that impurity in the runner can be discharged irrigator.
For achieving the above object, the technical solution adopted in the utility model is: comprise dropper and the flexible sheet that is arranged in the dropper pressure regulation district, flexible sheet is provided with the lid that drips that matches with flexible sheet, be characterized in, the parallel labyrinth runner that offers on the circumference of dropper also offers the belt labyrinth runner of arranging that is connected with labyrinth runner under the flexible sheet in the pressure regulation district of dropper.
Another characteristics of the present utility model are: the height h of labyrinth runner and ring-like labyrinth runner is 2.4mm, and width m is 2.67mm, and arc radius R is 1.2mm up and down, and the boss width s that turns round is 0.5mm.
Because the utility model is provided with the annular labyrinth flow-path that is connected with labyrinth flow-path under the pressure regulation district of dropper flexible sheet, by irrigator pressure regulation district's flexible sheet and the anti-variation of blocking up the fit dimension of labyrinth flow-path of the annular under it, under different pressures, accurately control the discharge in the labyrinth runner, thereby the rate of discharge that makes pressure compensation douche keeps constant, this labyrinth runner has been removed the mobile stagnation region in the runner, its anti-clogging excellence.
Four, description of drawings
Fig. 1 is the structural representation that labyrinth runner is set on the utility model circumference;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the arrange structural representation of labyrinth runner of annular under the flexible sheet in the utility model pressure regulation district;
Fig. 4 is that the utility model drips and covers structural representation;
Five, embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,2,3,4, the utility model is except offering on the circumference of irrigator dropper 1 labyrinth runner 4, also the flexible sheet in the pressure regulation district of dropper 1 also is provided with the labyrinth runner 5 that the annular that is connected with labyrinth runner 4 is arranged for 3 times, labyrinth runner 4 and labyrinth runner 5 have been removed the mobile stagnation region in original runner, and labyrinth runner is cyclically-varying, and the height h of runner is 2.4mm, width m is 2.67mm, and arc radius R is 1.2mm up and down.The boss width s that turns round is 0.5mm.
During the utility model work, water is at first by dropper 1, inlet grid 6 by dropper 1 enters irrigator, drip in the ring-like labyrinth flow-path 5 that covers under the water inflow pressure compensation regulatory region flexible sheet 3 owing to be provided with, at this moment, along with the fluctuation that enters water pressure in the dropper 1 changes, the cross sectional dimensions that flexible sheet 3 and the ring-like labyrinth flow-path under it 5 form closed flows will change, when the water pressure that enters dropper 1 increases, flexible sheet 3 cooperates the cross sectional dimensions of the closed flow that forms to reduce with ring-like labyrinth flow-path 5 under it, overcurrent discharge in the ring-like labyrinth flow-path 5 is reduced, promptly do not increase with the increase that enters water pressure in the dropper 1; When water pressure reduced, flexible sheet 3 cooperated the cross sectional dimensions of the closed flow that forms to increase with ring-like labyrinth flow-path 5 under it, and the overcurrent discharge in the ring-like labyrinth flow-path 5 is increased, i.e. reducing and reduce with water pressure not.Can accurately control the discharge in the labyrinth runner like this, thereby the rate of discharge of regulating pressure compensation douche keeps constant, stable then current enter to be arranged on circumference in the anti-stifled circular arc labyrinth runner 4, and it is stable to carry out further energy dissipating at this.The labyrinth flow-path that the utility model adopts is the circular arc labyrinth runner, this labyrinth flow-path has been removed the mobile stagnation region in the runner, its anti-clogging excellence, as enter in the water in the irrigator minute impurities is arranged, also can assemble for 3 times at flexible sheet, the flow in pressure regulation district and pressure are reduced, flexible sheet 3 floats, runner is crossed the water sectional dimension to be increased, and impurity will enter emitter outlet, flows out with current.
The utility model has reduced the arc section of labyrinth flow-path, and arc size is identical up and down, has reduced the height of runner, has removed the mobile stagnation region in the runner, has reduced the complexity that design of labyrinth type irrigator and mould are made, and has saved cost.
