SALT DOSING DEVICE FOR HYDRAULIC SYSTEM Russian patent published in 2025 - IPC B01F21/20 B01F25/316 C02F5/08 C02F1/68 C02F103/02 

FIELD: dispensing devices; heating.

SUBSTANCE: invention relates to a cartridge element of a device for dosing salts, in particular polyphosphates, for a hydraulic system, in particular a heating system. Cartridge element (10) of device (100) for dispensing salts for a hydraulic system, which comprises connecting element (20) having first connector (21), second connector (22) and connecting sleeve (23) in fluid communication with said first connector (21), and also comprises containing element (30) adapted for connection with said connecting element (20), together with which it defines inner compartment (V), wherein coupling sleeve (23) faces said compartment. Cartridge element (10) comprises tubular outer wall (11), which limits working chamber (11c) from inside and together with containing element (30) forms cavity (I) outside said outer wall (11). Separation wall (12) divides working chamber (11c) into first chamber (13) and second chamber (14), adapted to contain salts to be dispensed, and has at least first passage section (15) for providing fluid communication of said first chamber (13) with said second chamber (14), and also has second passage section (16) for providing fluid communication of said second chamber (14) with said first chamber (13), or said second chamber (14) with cavity (I). Cartridge element (10) also comprises pressure reducing means (18a, 18b) designed to create pressure difference in fluid passing through them.

EFFECT: improved dosing of polyphosphates in a hydraulic system and especially in a heating system.
