摘要： A gas range includes a burner, a burner control unit, a piezoelectric igniter and a safety valve. The safety valve is situated between a gas supply and the burner. A thermocouple is situated near the burner. The piezoelectric igniter is used to ignite gas which vents out of the burner. As a flame occurs at the burner, a temperature at the burner will ascend. The thermocouple detects the increased temperature and generates a current to open the safety valve. If the flame goes out, the temperature will descend to the predetermined value. The thermocouple detects the decreased temperature and stops generating any current to actuate the safety valve. Thus, the safety valve is closed so as to keep any gas from venting out of the burner.

摘要： The movable elements of two normally closed valves are actuated by a thermal element responsive to ignition at a pilot burner supplied fuel through one of the valves. The two valve elements form a mechanical train from the thermal element which simultaneously unseats the second valve controlling fuel to the main burner and releases a manually operable mechanism with which the pilot burner valve is initially unseated for ignition.

摘要： A valve rod of a gas heating device actuates not only a microswitch, but also a disc valve. A pilot burner and a main burner are separately controlled by individual solenoid operated valve which is serially connected. The disc valve is provided at the upstream of the pilot burner, and between two solenoid operated valves for safeguarding against the erroneous on-state of the microswitch. A sensor will, according to the presence of the pilot flame, instruct an electric control board to continue or discontinue the sparkling of an igniter, to open or close the solenoid valve for supplying gas to the main burner. Thus, the adversity of toxication caused by either the misfunction of microswitch or failure of valve actuation is able to be prevented.

摘要： A gas flow controller for use in a gas fired apparatus includes an actuator, a pilot valve operably connected to the actuator, a main burner valve, and a flow controller valve operably connected to the actuator. The pilot valve is moveable from a closed position to an open position by actuation of the actuator to provide selective fluid communication between a gas inlet and a first fluid chamber. The main burner valve provides selective fluid communication between the first fluid chamber and a main burner outlet. The flow controller valve is moveable from a closed position to an open position by actuation of the actuator to provide selective fluid communication between the gas inlet and a back side of the main burner valve to maintain the main burner valve in a closed position when the pilot valve is in the open position.

摘要： A safety device for gas-fired equipment having a main gas supply control valve and a plurality of gas-taps each associated with a flame-producing burner. The device includes a plurality of switches each associated with a gas-tap and actuatable by the operation of the gas-tap, a plurality of heat responsive sensors each having a switching circuit operationally connected in circuit with a secondary control circuit and a timer, and a central control unit connected in circuit for receiving control signals from the output of each of the secondary control circuits, thereby controlling the state of the main gas supply valve. Upon the detection by a heat responsive sensor of the extinction of a fire from a burner when a gas-tap associated therewith is open, after a predetermined time period, the secondary control circuit connected to the sensor emits a signal to the central control unit for effecting the closing of the main gas supply valve.

摘要： A fail safe gas shut off system is provided for a gas appliance. Two normally closed valve stages are provided in series, with each stage operated by a bidirectional solenoid armature. When the armature moves in one direction, the first stage of the valve is opened to supply gas to a pilot burner and to the second stage of the valve. When the pilot flame heats an emissive element to produce sufficient radiation, a photovoltaic device illuminated by the emissive element produces current for an electromagnet which latches the first stage of the valve in its open position. The armature can then move in the opposite direction and open the second stage of the valve to supply gas to the main burner. In the event of pilot flame failure, the emissive element darkens, and current from the photovoltaic device ends. The electromagnet releases the first stage of the valve which is biased closed and cuts off gas flow to both the pilot and main burners.
