DEVICE FOR CONTROLLING FLOW RATE IN CLOSED WATER CONDUIT Russian patent published in 2016 - IPC G05D7/01 G01F15/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering and land reclamation and may be used for automatic water flow to consumer, as well as in self-pressurising systems with intermediate tanks. Device comprises tank 4, supply pressure pipeline 1 at end divided into two lines of pipes 2 and 3. Each line of pipes 2 and 3 is connected with tank 4 with partitions 5 and 6, dividing vessel 4 into two tight chambers 7 and 8 and one common chamber made up of tank 9. Partition wall 6 has outlet holes 10 and 11, gates 12 and 13. Pipes 2 and 3 with intake holes 18 and 19 are connected with pressure chambers 16 and 17, at bottom of which there are holes 18 and 19 with valves 20 and 21, which connected by hinged-lever mechanism made up of levers 22, 23, 24, 25, respectively with rods 28 and 29 with floats 26 and 27. Floats 26 and 27 are placed in vessel 9 separated from each other by closed partitions 32 and 33, in middle part of which there are outlet holes 34 and 35 at bottom of tank 9.

EFFECT: design of device is aimed at efficiency, simplification and reduction of metal consumption.
