Thermostatic mixing valve

Thermostatic mixing valve including:

• a valve body provided with an inner cavity, a first inlet for a first flow of water into said cavity, a second inlet for a second flow of water into said cavity, and an outlet for an exit of a third flow of mixed water from said cavity;
• a mixing device shaped to be placed in fluid connection with said first inlet, said second inlet and said outlet, and to define a mixing chamber for said first and second flow in said cavity, said mixing device being internally provided with a thermostatic actuating element that is movable along an operating direction;
• and
• a temperature adjusting device provided with a housing and with a positioning element that is slidable with respect to said housing, said positioning element being configured for adopting, by adjusting, a set position with respect to said housing, in a coupling configuration of said temperature adjusting device with said mixing device, said positioning element being also configured for imposing on said thermostatic actuating element a calibration position along said operating direction corresponding to a desired mixing temperature;
• said mixing device including a plug member connected to said thermostatic actuating element and drivable along said operating direction through the effect of a contracting/dilating movement of said thermostatic actuating element for controlling the entry of said first flow and said second flow in said mixing chamber so as to maintain said third flow at said desired mixing temperature, wherein said mixing device is removably housed in said cavity by coupling at least one abutting portion of said mixing device with at least one abutting surface of said cavity, in that on said valve body, in a position opposite to said outlet, an opening end is obtained to enable said mixing device to be inserted into said cavity, in that said temperature adjusting device, in said coupling configuration, is shaped for coupling with said mixing device along a coupling surface and for closing said opening end, and in that said positioning element is configured for remaining in said set position with respect to said housing also in a decoupling configuration in which said temperature adjusting device is decoupled from said mixing device and from said body valve, so as to preserve, once said temperature adjusting device, said mixing device and said valve body have been recoupled, said calibration position corresponding to said desired mixing temperature.
