Non pressure compensated drip irrigation emitter with multiflow facility
Abstract:
Described is 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; 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, the third pool in the middle; a labyrinth in fluid communication with each pool and the filter system, the labyrinth comprises 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.
