Title:
A NON PRESSURE COMPENSATED DRIP IRRIGATION EMITTER WITH MULTIFLOW FACILITY
Document Type and Number:
WIPO Patent Application WO/2011/104722
Kind Code:
A3
Abstract:
The present invention provides a non pressure compensated drip emitter with multiflow facility, the drip emitter being placed inside a pipe of a drip irrigation system, the drip emitter comprising: a housing; at least two inlets through which water enter inside the emitter; a filter system being fitted at each inlet to ensure pure supply of water inside the emitter; three pools of water from only one of which water get discharged out of emitter and from emitter to the land to be irrigated via opening provided over periphery of the pipe of the drip irrigation system, the two pools out of three having the same capacity of discharging the water at a first flow rate and the said two pools are placed at the ends of the housing, the third pool is placed in the middle and having a capacity of discharging the water at a second flow rate, the second flow rate being greater than the first flow rate; a labyrinth in fluid communication with each pool and the filter system, the water entering through each inlet passes into labyrinth through respective filter system and from labyrinth to the outside of the pipe through one of the pool depending upon the selected flow rate of water, the labyrinth comprises a plurality of zigzag water paths; wherein the labyrinth connects middle pool with remaining two pools through the zigzag water path in such a way that even in case of partial clogging of the zigzag water path, the remaining partial zigzag water path remain active and ensure the discharge of water at a selected flow rate from the emitter.
