1) Usage: it is suitable for gas heaters, gas burn oven, gas appliances as control component.

 

2) Working principle: thermocouple and supporting the use of electromagnetic valve is composed of gas safety protection devices, remove thermocouple is a microprocessor can provide the power transducer, electromagnetic valve is the control elements, when thermocouple tips when heated by fire department, cold and heat generated due to the difference between the thermoelectric power, therefore, to form closed loop current in the external magnetic solenoid valve and the incentive effect, in which, the gas absorption, when the flame, thermocouple rapidly lose potential, electromagnetic valve is lost in the suction under the action of compression spring and gas path, and safety protection.

 

3) Scope: natural gas, liquefied petroleum gas, the artificial coal gas.
