WATER SOFTENING DEEVICE CONTROL VALVE DISTRIBUTION UNIT Russian patent published in 2025 - IPC F16K11/74 C02F5/00 

FIELD: water treatment.

SUBSTANCE: invention relates to the field of water treatment, namely to the distribution unit of the multi-way control valve of the water softening (demineralisation) device. Distribution unit comprises fixed element (1) and movable element (2) installed in contact with fixed element (1) along end surface and with possibility of rotation relative to fixed element (2) along specified end surface. Fixed element (1) comprises first opening for inlet into filtering column (101), second opening for inlet into filtering column (102), ejector inlet opening (103), water outlet opening (104), first opening for outlet from filtering column (105), second opening for outlet from filtering column (106) and ejector outlet opening (107). Movable element has first recess (201), second recess (202) and third recess (203), made with possibility of alignment with openings (101-107) of fixed element (1) to provide for the passage of the water flow by the valve in the modes of filtration, regeneration, back flushing, direct flushing and filling of the salt tank. First recess (201) of the movable element is made with possibility of simultaneous alignment with the opening for inlet of filtering column (101) and with the opening for the outlet of filtering column (106) of fixed element (1) with provision of additional bypass mode, in which one part of inlet water flow is supplied to filtering column, and the other part of the inlet flow is supplied directly to the outlet of the filtering column bypassing filtration, after which the said parts of the flow are mixed and supplied to water outlet (104).

EFFECT: invention is aimed at expansion of functional capabilities of the device due to provision of additional control of water hardness by adding to the flow of desalinated water of the initial flow (bypass mode) without complicating the design of the control valve.
