    摘要: A gas fire system comprises a gas valve (104), a spark generator (108) for igniting a gas flowing out of the gas valve (104), a microprocessor-based controller 106 for controlling the operation of the gas valve (104) and the spark generator (108) and a user interface (110, 112) for providing instructions to the controller (106). The gas valve (104) comprises a valve body (202) having a gas inlet (266), a main gas outlet (268) and a bore (212). The bore (212) has an interior surface (298) a part of which defines a gas flow cavity, the gas inlet (266) and the main gas outlet (268) being in communication with the gas flow cavity. The gas valve (104) further comprises a valve spindle (206) arranged to move into and out of the gas flow cavity, an exterior portion of the valve spindle forming a flow control surface (262) and defining a gap having a volume between the flow control surface (262) and the interior surface (298) of the gas flow cavity. Relative movement of the flow control surface (262) and the gas flow cavity varies the volume of the gap and regulates a flow of gas from the gas inlet (266) to the main gas outlet (268).

    摘要: A dual fuel heater (10) includes a pressure regulator converter (11) in fluid communication with a control valve which in turn is in fluid communication with a selector valve (40) through a NG/LP pilot line (48) having a splitter (49) to form a. NG pilot line (50) and a LP pilot line (51) extending to an LP pilot nozzle (67). The selector valve is moveable between an NG “on” position wherein fuel entering the selector valve passes to a burner (60) and to a NG pilot nozzle (65), and an NG “off” position (LP “on” position) wherein fuel passes to the burner and not to either the NG pilot nozzle or the LP nozzle. The NG pilot nozzle is oriented so that its flame heats the first thermocouple associated with the NG pilot nozzle and ignites fuel expelled form the LP pilot nozzle.

    摘要: A gas safety device is provided. An electronic valve connected to a thermocouple is closed to cut off the gas supply when the temperature of radiant heat directly emitted from a surface of a vessel exceeds a preset temperature level while the vessel is heated through the spark ignition of a burner, thereby preventing risks of overheating and thus fire caused due to a user's carelessness when the user cooks the food.
