MEMBRANE-FREE 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 provision of drinking and industrial water for low-rise buildings of cities, rural settlements and dacha cooperatives, as well as in chemical production and in water treatment and waste water storage systems of passenger rail cars. The membrane-free hydraulic accumulator contains a hollow storage tank 1, in the lower part of which there is a water storage cavity 2 with a water supply pipe 4, and in the upper part there is an air cavity 3 for water-compressed air. New distinctive features of the hydraulic accumulator in comparison with the well-known /RU 2220367/ are: creation of a technological window in the upper part of the tank body 1 for preventive inspection and cleaning of the cavities of the tank 1; installation and hermetic fastening of a quick-release head 5 in the technological window; installation of a pressure relay 9 with a compressed air pressure indicator 8 in the tank 1; connection of the relay 9 and the pressure indicator 8 through the pneumatic inlet to the air cavity 3 of the tank 1; making the water supply pipe 4 removable and hermetically fixing it in the quick-release head 5 with a quick-release coupling 20; installing an indicator 19 on the side surface of the storage tank 1 for monitoring the limit values of the volume of compressed air in the tank 1.

EFFECT: invention makes it possible to increase the reliability of the hydraulic accumulator while reducing the time spent on preventive maintenance and cleaning of deposits in the cavity of its storage tank.
