Definitions

  • the present invention relates to a device for automatically actuating valves for shutting off the fluid supply in heating elements.
  • thermostatic valves mounted on radiators and/or similar heating elements are known, these valves allowing the quantity of hot water circulating inside the radiators to be regulated so as to keep the ambient temperature at the desired level.
  • valves The operation of said valves is based on an increase/decrease in volume - depending on the ambient temperature detected - of a temperature-sensitive element (gas, wax, bimetallic strip) contained in the valve itself.
  • a temperature-sensitive element gas, wax, bimetallic strip
  • the variation in volume of said element actuates a shutter device in the water supply pipe, the displacement of which in one direction or the other causes a variation in the quantity of hot water circulating in the radiator, thus determining the corresponding ambient temperature.
  • valves have a ring comprising a graduated scale with numbers corresponding to predefined variations in the volume of the sensitive element with respect to a fixed index; as a result it is possible to ensure a certain correspondence between the graduation of the valve and the desired ambient temperature which is to be verified using a thermometer outside of the valve.
  • valves with which it is possible to achieve the desired ambient temperature depending on the predefined graduation, although performing their function, do not allow a variation in the prechosen temperature which remains fixed, unless manual adjustment of the valve is performed directly by the user.
  • the technical problem which is posed, therefore, is that of providing a device for actuating valves for shutting off the supply of heating elements, able to produce at least a variation in the graduation of the valve during a predefined time interval.
  • said device should be easy to adapt also to thermostatic valves which are already installed and should not require connections to the electrical mains for powering thereof.
  • a device for automatically actuating valves for shutting off the fluid supply of heating elements comprising a container which has arranged, inside it, at least one wheel which is connected to the element for operating the valve and which can be actuated rotationally by means of a motor controlled by an associated circuitry, at least one receiving element able to receive a signal emitted by a transmitter outside the device and send it to the control circuitry of the motor, at least one independent power source also being provided for supplying power to the motor and the electrical circuits.
  • the actuating device 100 may be fitted, by means of an adapter 30, to a valve 10 mounted on the supply pipe 21 of a radiator 22.
  • the device 100 essentially consists of a casing 101 which has, arranged inside it, a toothed wheel 102 rotationally moved by means of a chain of reducer gears 103a, 103b actuated by a motor 104 connected to an associated electrically operated printed circuit 104a.
  • the adapter 30 for connection to the valve 10 is coaxially joined to the toothed wheel 102.
  • the device also comprises a receiving antenna 106 connected to an associated amplification circuit 106a and able to receive signals from a transmitting device (not shown) essentially consisting of a programmable timer.
  • Both the motor 104 and the circuitry 106a of the antenna receive power from suitable batteries 107 housed in the casing 101.
  • end-of-travel elements 102a for example, of the "rider" type, so as to define a circumferential section corresponding to a predefined angular degree of rotation in one direction or the other about a predefined zero reference point. It is envisaged, however, that said end-of-travel devices may be of the electronic type and able to control actuation of the motor.
  • this rotation is correlated to a graduated scale -2 / 0 / +2, the numerical values of which correspond to an equivalent number of angular intervals corresponding to rotation of the operating knob of the thermostatic valve which causes a - for example unitary - variation in the graduation of the valve itself (variation of the index set).
  • the device also envisages a fastening element 108 for fixing the container 101 to a fixed part, so that actuation of the motor causes rotation of the wheel 102 alone.
  • the operating principle of the device is as follows:
  • a practical example of operation of the device consists in the need to have two different daytime/night-time temperatures during the twenty-four hour period.
  • the actuating device may be operated by control elements such thermostats and/or so-called timer thermostats of the type used to obtain programming of a multiplicity of temperature values over the twenty-four hour period, whereby the programming may be always the same or different for the seven days of the week depending on whether programmers of the daily and/or weekly type are used.
  • the temperature-sensitive element which determines greater/smaller opening/closing of the valve
  • the actuating device may be directly connected to the supply shut-off valve, which may also not be of the thermostatic type.
  • the transmission of the command pulses from the remote transmitter to the actuating device may be performed via cable, instead of via radio, even though this requires the provision of the necessary cables.
