Presented is a system and method for permitting concurrent actuation of a gas safety valve and an ignition trigger for igniting gas burners. The combination safety valve and ignition device for gas burners permits both the start of a flow of flammable gas to a burner and the ignition of the flammable gas via operation of a single button or other actuator.
摘要:
A hot wire type of gas ignition system uses a negative temperature coefficient resistor-ignitor element that is deenergized after ignition has occurred. The ignition and safety monitoring of the circuit is accomplished by a second flame detector means, and the flame responsive circuit that has been disclosed in a flame rectification circuit.

The present invention relates to a safety device for gas-fired heating apparatus (generally called a "magnetic head") constituted by an assembly mounted on a gas supply pipe and comprising an electromagnetically controlled valve. It comprises an intermediate element made of electrically insulating and elastically deformable material, presenting on the one hand at least one substantially cylindrical portion extending between the opposite cylindrical zones of the support and of the connector element which is fixed on said intermediate element by crimping of one of its ends, on the other hand a plurality of arms extending longitudinally and forming a housing for the core, at least certain of them being provided with hooking members or the like.

A gust-protecting safety pilot enclosure utilizes a hood which directs the pilot flame in two tongues, one of which heats a thermocouple within the enclosure and the other extends slantingly through the upper portion of the enclosure wall to ignite the main burner. A horizontal air flow opening in the enclosure wall beyond the thermocouple serves, when the pilot flame height is reduced, to divert a portion of the flame from the tongue which extends toward the thermocouple to the tongue which extends toward the main burner, thereby to prefer ignition of the main burner over voltage output from the thermocouple.
摘要:
A gas burner control device including a biased closed, electromagnetically operated, fuel cutoff valve dependent upon electrical energy generated by a pilot burner-heated thermocouple to hold it open, and a biased open pressure responsive switch controlling the thermocouple-cutoff valve circuit, the switch being dependent upon a predetermined minimum gas supply pressure to close it and hold it closed, whereby either a drop in fuel supply below a predetermined minimum pressure or the extinguishment of the pilot flame effects closure of the fuel cutoff valve.

A VALVE HOUSING INCLUDES A PILOT VALVE AND A MAIN VALVE MOVABLE ALONG A COMMON AXIS TO OPEN AND CLOSE THE VALVES. AN OPEATING MECHANISM FOR THE VALVES INCLUDES A CAM SUPPORT AND A CAM POST CONTACTING A CAM ON ONE SIDE OF THE SUPPORT. A HANDLE IS OPERATIVELY CONNECTED TO THE SUPPORT SO THAT IT CAN BE ROTATED TO A POSITION AT WHICH THE PILOT VALVE IS OPEN. THE BURNING OF THE PILOT VALVE CAUSES A LATCH TO HOLD THE SUPPORT IN THE ROTATED POSITION. REVERSE ROTATION OF THE POST, CAMS THE ROTATIONALLY LATCHED SUPPORT SO AS TO OPEN THE MAIN VALVE. A HANDLE IS CONNECTED TO ROTATE THE POST AND ALSO A RING GEAR. AXIAL DISPLACEMENT OF THE HANDLE AXIALLY MOVES THE GEAR TO A POSITION AT WHICH IT ENGAGES A GEAR ON A PIEZOELECTRIC LIGHTER, WHEREUPON ROTATION OF THE TWO GEARS ACTUATES THE LIGHTER.
