IRRIGATION SYSTEM Russian patent published in 2009 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: irrigation system consists of water source, pumping station with isolation valves and pressure gauge, main pipeline, subsoil irrigation and drop irrigation distributing pipelines connected in series, irrigation pipelines distributed in parallel along the distributing pipelines and distributed at specified regular intervals perforated-pipe spray jets perpendicular to them (subsoil irrigation) and flexible drip lines (drop irrigation). Cyclone, sand-and-gravel filter and strainer, as well as pressure gauge and isolating valves are installed in hydraulic circuit of drop irrigation main pipeline. Header tank is installed between two gate valves for water pressure feeding to subsoil irrigation area. Each reducer between distributing pipeline and irrigation pipeline contains isolating valves, fine filter, purified irrigation water supply flow meter and service unit connected in series. Header tank is provided with a pressure tank. A watertight barrier is installed under each spray jet (perforated polyethylene pipe). Water flow equaliser (polyethylene film reinforced with gas-expanded plastics) is installed over the spray jet pipe.

EFFECT: reduced power consumption of pumping station drive, increased efficiency of subsoil and drop irrigation.
