DAMPING VALVE ASSEMBLY Russian patent published in 2021 - IPC E03B7/07 

FIELD: damping devices.

SUBSTANCE: damping valve assembly (40) is used in a liquid distribution system that has a centrally located liquid source connected through at least one supply pipeline (41) to at least one tap assembly (42) for liquid. At least one supply pipeline (41) is made with the possibility of pumping liquid out of it after closing corresponding tap assembly (42) and refilling with liquid after opening the tap assembly. Damping valve assembly (40) contains damping chamber (26) made with the possibility of connection, when used, to at least one specified supply pipeline (41), and shut-off valve assembly (1’) also made with the possibility of connection, when used, at its inlet end (22), to specified corresponding supply pipeline (41) and having outlet end (24) made with the possibility of connection, when used, to at least one specified corresponding valve assembly (42) for liquid. Damping chamber (26) is designed for gas collection and is made with the possibility to be connected to supply pipeline (41) through passage (23) of damping valve assembly (40). Passage (23) is directly connected, without any restrictions between them, to shut-off valve (2, 18) for liquid at specified inlet end (22) of specified shut-off valve assembly (1’) for liquid. Passage (23) is always open on damping chamber (26) for connection with the possibility of transferring fluid between passage (23) and damping chamber (26).

EFFECT: smooth and efficient operation of the device is ensured.
