Abstract (en)

[origin: EP1895245A2] Single-piece multifunction valve for supplying and controlling hot water (C) supplied to user appliances (U) comprising a body (100) having formed inside it: a delivery branch (RM) for the hot fluid (C) substantially formed by an inlet aperture (101) and an outlet aperture (102) to the user appliances (U); a return branch (RR) for the cold fluid (F) from the user appliances (U), substantially formed by an inlet aperture (201) for the cold water (F); an outlet aperture (202) for return of the cold fluid to the boiler (CT); said delivery branch (RM) comprising at least a filtering chamber (110) terminating in an annular seat (111) for housing a filter (1000) and communicating with the exterior by means of an aperture (112) able to be closed/opened by means of an associated plug (113); a bypass chamber (120) communicating with the exterior by means of a substantially vertical aperture (121) able to house a bypass valve (2000) provided with an obturator (2001) able to come into contact with the seat (122a) of a first end of a vertical duct (122) suitable for connecting the delivery branch (RM) to the return branch (RR) of the valve; a temperature measuring chamber (130) which communicates with the exterior by means of a substantially vertical aperture (131) formed in the bottom side (100e) of the valve body and able to house a water temperature detection probe (3000) emitting a corresponding electric signal; and said return branch comprising at least a shut-off chamber (210) for the cold water (F) of the return branch (RR) communicating with the exterior by means of a substantially vertical aperture (212) and able to house a shut-off valve (4000) provided with an obturator (4001) which can be opened/closed by means of an associated actuator (4100) controlled by the control unit (5000) ; said shut-off chamber (210) being connected to the delivery branch (RM) by means of said vertical duct (122) of the bypass chamber (120) for recirculation of the fluid; a balancing chamber (220) communicating with the exterior by means of a substantially vertical aperture (221) formed in the upper side (100d) of the valve body and able to house a balancing valve (6000) provided with an obturator (6001) able to determine a greater/smaller flow of the cold return fluid.
