PULSED SPRINKLING IRRIGATION SYSTEM Russian patent published in 1994 - IPC

FIELD: crop irrigation. SUBSTANCE: irrigation system has pumping station and command pulse generator installed in head of water distributing pipeline, sprinkler pipelines and pulsed sprinklers. The latter are connected through hoses and flow rate and pressure fluctuation cutoffs which have flexible ball able to pass through hole in both directions. This precludes direct action of pressure fluctuations in betwork on working space of shutoff member in case of pressure drop in system and double discharges, and excludes also water drain from system into atmosphere in case of failure of shutoff member of pulsed sprinkler. EFFECT: enhanced reliability and efficiency. 3 dwg
