Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the compensation drip emitter of one that Fig. 1 provides for the utility model, comprise: irrigator first cavity 10, elastic block piece 20 and irrigator second cavity 30, described irrigator first cavity 10 is fixedly connected with described irrigator second cavity 30, described elastic block piece 20 is fixedly arranged in the hermetically-sealed construction that described irrigator first cavity 10 and described irrigator second cavity 30 be fixedly connected to form, and described elastic block piece 20 is for regulating the water flow of described compensation drip emitter flowing; Wherein, the first end of described irrigator first cavity 10 is provided with water inlet 40, and the second end of described irrigator first cavity 10 is provided with draw-in groove; The outer surface of described water inlet 40 is provided with screen pack; Described irrigator first cavity 10 is inner is provided with arc convex structure with water inlet 40 junction; The width of described elastic block piece 20 is less than the width of the interior that described irrigator first cavity 10 is formed with described irrigator second cavity 30; Described elastic block piece 20 is inclined to the direction of described irrigator second cavity 30; The first end of described irrigator second cavity 30 is provided with bulge-structure, and described in described bulge-structure territory, the draw-in groove of irrigator first cavity 10 is fixedly fastened and connected; Described irrigator second cavity 30 is provided with outer chamber wall and inner chamber body; The outer chamber of described irrigator second cavity 30 is provided with sawtooth runner; The first end of described sawtooth runner is provided with runner water inlet; Second end of described sawtooth runner is provided with runner water inlet; The first end of the inner chamber body of described irrigator second cavity 30 is provided with delivery port, and the water inlet 40 that the first end of described delivery port and described irrigator first cavity 10 sets firmly matches.
Operation principle of the present utility model is: current enter irrigator first cavity 10 from the filtering window of water dropper water inlet, flow through elastic block piece surface and enter sawtooth runner through sawtooth flow channel entry point, entered the irrigator second cavity arrival delivery port of elastic block piece bottom by sawtooth runner exit after the preliminary energy dissipating of sawtooth runner, along with the continuous change of pressure, there is corresponding change thus change discharge in the water outlet cross section of elastic block piece bottom.Under normal pressure, the outlet of irrigator is nature cross section state, and flow is comparatively large, and when the pressure was increased, elastic block piece sink, and use mouth of a river area and diminish, discharge diminishes; Thus play and keep the flow of irrigator constant when pressure changes.When pressure little to a certain extent time, elastic block piece just departs from irrigator second cavity completely, and water chamber volume becomes very large, and water outlet cross section also becomes large, and flow is corresponding increase also.
Compared with existing irrigator device, the utility model provides a kind of compensation drip emitter, by irrigator first cavity, the three-decker design of elastic block piece and irrigator second cavity, and the internal structure design in the design of this three-decker, solve the uncontrollable irrigation efficiency that causes of compensation type emitter pressure regulation spectrum in prior art lower, affect the problem of people's production efficiency and social life thus, improve irrigation efficiency, and and then improve the availability of water resource.
