Definitions

  • the invention relates to a new gas flow control valve applicable to radiant heaters having two or more burners, and the arrangement of the actual valve with respect to the burners as a whole.
  • the object of the invention is to provide a valve in which the gas flow to one, two or more burners in a radiant heater may be controlled, relying upon a simple and effective mechanism that may be easily worked.
  • the object of the invention is also the arrangement of the valve close to the burners in order to avoid the respective gas flow ducts and connectors.
  • the valve with which the gas flow to such burners and towards the actual lighting system is controlled is mounted in an area close to the respective control knob, specifically in contact therewith, which results in the actual valve lying at a distance from the burners, thereby requiring gas ducts to be laid out from said valve to the various burners existing at each radiant plate.
  • valve disclosed herein solves the aforesaid drawbacks based upon a new approach as regards construction, operation and indeed arrangement within the heater as a whole.
  • valve of the invention comprises, as is conventionally the case, a tubular body with a branch for the gas main to be coupled, another branch for the duct supplying the burner, and a bore for mounting the elements that open and shut the outlet toward the burners, and for mounting the control knob.
  • the structure of the inventive valve is particular in that it is on the one hand assembled close to the burners, being coupled thereto through ducts provided in the actual valve, without there being any need for the classic conventional ducts required in conventional radiant heaters, which gas ducts and their connectors and sealing gaskets are therefore eliminated, thereby for the cost of the heater to be reduced, because parts are eliminated, and for the risk of gas leakage to be improved.
  • valve body includes an axial bore in which a shaft, which is axially arranged with respect to another shaft upon which the control knob is mounted, is slidable, both of which shafts are biased towards an idle position in which the supply of gas both to the ducts coupled to the burners and the duct supplying the lighting system is hence cut off.
  • the inner shaft can be driven by pushing the outer shaft against the action of a spring, and therefore upon said outer shaft being pushed inwards, the internal shaft slides, which results in a gasket being moved by the free end of said inner shaft against the action of a spring, which gasket when at rest tends to shut off the flow or communication between the branch through which gas is supplied to the valve and the duct leading towards the first burner.
  • a gasket when at rest tends to shut off the flow or communication between the branch through which gas is supplied to the valve and the duct leading towards the first burner.
  • the outer shaft or, in other words, the control knob In order for opening to take place and hence for gas to flow and be communicated towards the second burner, the outer shaft or, in other words, the control knob, must stop being pushed, whereupon the shaft will tend to retrieve the original position due to the spring associated therewith, which outer shaft must concurrently be turned to allow the inner axial shaft to move back and thereby the latter's gasket to move to enable a flow towards the second burner, which outer shaft must be turned in order for a spigot solidly attached thereto to run along a peripheral groove or slot of the valve body and thereby allow the retraction of said outer shaft of the control knob and hence the axial shaft opening and shutting off the flow to the respective burners.
  • the main characteristics of the valve lie in the fact that it includes or is provided with two sliding axial shafts, both of which are associated with return springs, the outer shaft having cotter means in order that, upon being turned, it may be moved backwards and hence so may the inner axial shaft be moved in order for gas flow to be opened or communicated with the burners.
  • the general valve body be mounted close to the actual burners, thereby eliminating gas flow ducts and connectors, avoiding possible risks of leakage in conventionally required installations.
  • valve subject of the invention applies to any type of radiant heater which, in the case in hand, is a heater (2) having a pair of plates (3) and (3') which may be supplied through their respective burners (4) and (4'), the heater moreover including the corresponding lighting system (5) with a duct (6) through which gas is supplied to such lighting system (5), all as is conventionally the case.
  • the valve (1) of the invention includes a branch (7) for the general gas main (8) to be coupled, and therefore based upon all of these characteristics, said valve (1) is particular in that it is fitted with a pair of branches (9) and (9') through which the valve (1) is coupled directly to the burners (4) and (4').
  • said valve (1) is mounted or arranged within the heater as a whole in an area close to the heater's actual burners, which means that there are no conventionally required gas flow ducts and all risk of leakage is therefore avoided.
  • the valve (1) moreover has an axial bore (10) within which an inner axial shaft (11) having an annular stop (12) at approximately the midpoint is slidingly mounted, said shaft (11) being associated with a spring (13) which constantly biases same inwards, said sliding being limited by a sealing gasket (14).
  • the inner free end of said shaft (11) faces a gasket (15) which shuts off the gas flow into the valve when the valve is in the idle position shown in figure 1, whereas the gasket 14, as shown in figure 2, is the means shutting off the gas flow to the second burner (4').
  • Facing the inner axial shaft (11) is another shaft (16) whose outer end terminates in a head (17) in which the respective control knob may be coupled, said outer shaft (16) being constantly biased by a spring (18) and further having a spigot (19) which plays within a peripheral groove serving as a cotter (20), provided in the actual valve body (1).
