Company business scope

This company specialized production each kind of specification variety gas use series thermocouple, applicable to gas cookers, gas water heater (the condensing gas water heater), the boiling water, gas boiler, gas ovens, oven, gas heating water heaters, gas air conditioning, the refrigerator, etc.

Thermocouple working principle

Thermocouple and electromagnetic valve supporting the use of gas stoves flameout of safety protection devices, thermocouple is a kind of can provide the power of the transducer, electromagnetic valve is the control elements, when thermocouple very tip flame heating by the cold end and hot end due to temperature difference between produce thermoelectric potential, therefore form closed loop current, make the electromagnetic valve in the external forces and magnetic field under the common function of incentive, in close states suck, gas flow, when the flame is extinguished, thermocouple rapidly lose potential, electromagnetic valve lost suction by compression spring in under the action of reset, and shut down gas path, thus plays security protection.

Use gas species

Liquefied petroleum gas, natural gas, the artificial coal gas

Ambient thumidity

(45~85)%RH

Thermocouple temperature

500°C~750°C

Working temperature: tip temperature is not higher than 750 ° C, the rest of the higher than 125 ° C.

Thermocouple technical performance requirements:

Open valve current<80mA

Close valve current>20mA

internal resistance(20°C) 20±15%mΩ

The compression spring force 2.5N±10%

matters need attention

 

Thermocouple are hot department (i.e. head) the "carbon.

 

Special specifications of thermocouple can according to the requirements of customers, custom.
