FLOWING MEMBRANELESS HYDRAULIC ACCUMULATOR Russian patent published in 2021 - IPC E03B11/00 

FIELD: water supply systems.

SUBSTANCE: invention relates to water supply systems and can be widely used for the accumulation and supply of drinking and industrial water to low-rise buildings in cities, rural settlements and country cooperatives, as well as in chemical production and in water treatment and wastewater storage systems for passenger cars of railway transport. The flow-through membraneless hydraulic accumulator contains a tank 1 with a storage cavity 2 for liquid in the lower part of the tank 1 and with a pneumatic cavity 3 for a gas compressed by a liquid in its upper part. Tank 1 is equipped with inlet 10 and outlet 11 nozzles for fluid inlet and outlet, respectively. New distinctive features of the accumulator in comparison with the known /RU 2220367/ are: execution in the upper part of the tank body 1 of the technological window 5, and in the lower part of the drain valve 14; installation and hermetic fastening in the technological window 5 of the quick-detachable head 9; fastening on a quick-detachable head 9 of a pipe input-output device (PIOD) and a pressure switch 6 (PS); the implementation of the PIOD in the form of two separately or coaxially located vertical pipes 13 and 12, connected to the corresponding inlet 10 and outlet 11 nozzles for liquid; connection of the pressure switch 6 through the pneumatic inlet with the air cavity 3 of the tank 1, and through the control output - with the electrical connector for connecting the cable 15 control of the device 17 for supplying liquid to the inlet pipe.

EFFECT: indicated differences make it possible to create a flow-through membraneless hydraulic accumulator suitable for use in the water supply and heating system of residential buildings and industrial premises, which increases the reliability of its operation and water supply, while reducing the time spent on preventive maintenance and cleaning deposits in the cavity of the storage tank.
