FIELD: aqua vending machines.
SUBSTANCE: invention relates to aqua vending machines, specifically to water vending machines by automatically controlled irrigation water supply from an aqua tank into a water filling chamber through its outlet branch pipe by means of a centrifugal pump with a "wet" rotor located in the hydraulic lock of the corresponding supply pipeline. Anti-vortex hydraulic system for aqua vending comprises aqua tank 1 with an outlet branch pipe 2 installed in bottom 3 of aqua tank 1, water filling chamber 4 with water filling pipe 5 into the water buyer container, hydraulically connected to outlet pipe 2 by means of pipeline 6, as well as centrifugal pump 7 with a "wet" rotor, equipped with a DC electric drive and hydraulically connected to the section of pipeline 6. Pipeline 6 is configured to form a hydraulic lock in it, in the zone of which there is pump 7. Hydraulic system comprises blade silencer 8 of water vortex, which is installed inside water tank 1 on its outlet branch pipe 2 on the side of inlet to this branch pipe 2. Silencer 8 comprises horizontal disc 9 and four L-shaped blades 10-13, permanently mounted on lower side of disc 9. Blades 10-13 are connected to each other to form an L-shaped cross-piece symmetrical relative to the axis of disc 9, so that each blade of this cross-piece is an L-shaped plate, which includes horizontal and vertical blade elements. Horizontal elements 14, 16, 18, 20 of four L-shaped blades 10-13 together form four-bladed horizontal flange of silencer 8, on which said disc 9 is located and which directly rests on bottom 3 of water reservoir 1 in the area of inlet to its outlet branch pipe 2. Vertical elements 15, 17, 19, 21 of four L-shaped blades 10-13 together form four-bladed vertical leg of silencer 8 located in outlet branch pipe 2.
EFFECT: imparting anti-vortex properties to the system due to killing of water vortex at the inlet to the outlet branch pipe of the aqua reservoir during operation of the centrifugal pump.
