When using thermocouples often see some of the news in the gas often seen on the thermocouple used in gas stove, gas stove then in a relationship with a thermocouple solenoid valve is to lose, they are a way to said to be complementary relationship, you can simply say that the thermocouple potential hot spots will make with the gas solenoid valve is turned on, if the unexpected flameout, the thermocouple hot trend disappeared, the solenoid valve will lose power, blocked gas channel, so that the gas is not exposed, to ensure personal safety and property security. As we mentioned thermocouple

Look at the thermocouple related things.

        A thermocouple is two platinum metal sheet at different temperatures produces a voltage difference between a pair of (two) different materials welded together alloy wire, when heated at one end, the other end of the cooling, can generate an electromotive force between the two alloy wire (voltage) of the alloy wire. The size of the decision generating an electromotive force

Scheduled to alloy wire material properties and the heating temperature. It consists of a metal wire, protective sleeve, and transmission line components. When heated in the flame, the thermocouple emf generated at both ends to the solenoid valve, the solenoid valve is energized to maintain pull, maintaining gas conduction; When an accident flameout, Lee

Thermocouple emf across the disappearance of the solenoid valve energized release, blocking the gas passage, to prevent gas spills.
        These are the gas stove why would suddenly turn off after the gas leak is not related to interpretation of this principle is the greatest merit of thermocouples, thermocouple hot spots is the use made ​​of the potential of principle.
