Device for treating a flow of water, particularly for a boiler of a heating and domestic hot-water generating system

摘要

The device comprises a holder body (2) in which a water-treatment cartridge unit (3) is fitted removably. The holder body (2) defines a cavity or chamber (4), at a first end of which a lateral inlet opening (5) for a water-flow to be treated and an end aperture (6) for the leaktight fitting and the removal of the cartridge unit (3) are formed. An outlet opening (7) for the treated water-flow is defined at the other or second end of the cavity or chamber (4). The cartridge unit (3) comprises a carrying structure (8) of moulded plastics material including:
- a first end portion (9) comprising a knob-like moulding (10, 11) and an adjacent sealing portion (12) suitable for being fitted in the end aperture (6) of the cavity or chamber (4) in a liquid-tight manner,
- an intermediate portion (15) which extends operatively in the cavity or chamber (4) and which carries a filter (16) through which the water-flow admitted to the cavity or chamber (4) for treatment is intended to pass, and
- a second end portion (18) remote from the first (9) and carrying a flow detector or measuring device (19) arranged hydraulically downstream of the filter (16).
