Product Description


Thermocouple head 

Working principle: Gas 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.
