Definitions

  • the present invention relates to a safety and regulation device for supplying gas to a burner, to a gas-heated appliance and in particular to a boiler, a water heater, starting on arrival. gas main and ending at the burner injectors.
  • the object of the invention is to reduce the cost and increase the reliability of the gas supply devices, thanks to a design involving few parts.
  • the subject of the invention is a device forming a multifunctional gas valve, comprising a housing which can be produced from an aluminum profile and which makes it possible to combine the safety, regulation and gas distribution functions. to the injectors.
  • This box can receive the control panel of the device on its upper face or on a side face and has two grooves in its upper part allowing to carry the control circuits of safety and regulation valves.
  • the housing consists of a part 4 and a cover 29.
  • the one-piece part 4 is produced from an aluminum profile cut to length and comprises two parallel conduits 5 and 6 partitioned by watertight plugs 9, 10, 11, 12 and 13, in order to obtain the safety chamber 14 , the intermediate chamber 15, the regulation chamber 16 and the distribution chamber 17 (feeder).
  • the cover 29 has grooves 3 for mounting an electronic card 30 carrying the control circuits of the various valves and carries on its upper face the control panel 36 of the device with, in particular, the operating buttons 31.
  • the gas arrives through the connector 8 and enters the chamber 14 where the safety valve 7 controlled by the safety valve 20 is located, this valve being in the closed position when the appliance is stopped or in safety and in the open position when the the device is operating normally.
  • the gas penetrates, through the orifice 18, into the chamber 15, then, through the orifice 19, into the chamber 16 where the regulating valves 21 and 22 are located, actuated respectively by the valves 23 and 24, these being in the open or closed position depending on demand.
  • the valves 21 or 22 When one or both of the valves 21 or 22 is open, the gas penetrates, through one or the other of the orifices 25 or 26 or through both, into the distribution chamber 17 on which are mounted injectors 27 which will supply the gas to the burners.
  • FIG. 2 illustrates the safety function which is carried out by the safety valve 20, which can be of the solenoid or thermoelectric valve type or any other means making it possible to ensure the safety function and which controls the safety valve 7 which opens or closes orifice 18 allowing gas to pass into the other chambers.
  • the safety valve 20 can be of the solenoid or thermoelectric valve type or any other means making it possible to ensure the safety function and which controls the safety valve 7 which opens or closes orifice 18 allowing gas to pass into the other chambers.
  • FIG. 3 illustrates the regulating function which is carried out by the regulating valves 23 24, which can be of the all-or-nothing or modulating solenoid type or any other means making it possible to carry out the regulating function and which control the valves 21 and 22 which open or close the orifices 25 and 26 allowing the passage of gas in the distribution chamber 17.
  • Figure 4 illustrates the distribution function performed by the chamber 17 which carries the injectors 27 ensuring the supply of gas to the burners.
  • FIG. 5 is a section of the profiled part 4 and shows the conduits 5 and 6. At its upper part, two grooves 28 make it possible to receive the cover 29.
  • the housing 43 of FIG. 6 consists of a housing body 32 and a cover 33, the housing body comprising, at its lower part, a gas conduit 34, and at its upper part, two grooves 35 receiving an electronic card 44 carrying the control circuits of the various valves.
  • valve seat carrier 37 of particular shape illustrated by FIGS. 7, 8 and 9, FIG. 7 being an external view of this seat carrier, Figure 8, a section along line VIII-VIII of Figure 7 and Figure 9, a section along IX-IX of Figure 8.
  • This valve seat holder is in the form of a hollow cylinder, with a transverse central partition 38 which carries the valve seat itself 39 with its orifice 40, the two cylindrical parts located on either side of the partition 38 having two recesses 41 and 42 but diametrically opposite one another.
