How the gas stove works

- Oct 08, 2018-

  The ignition mode of the gas stove mainly includes electronic pulse ignition and piezoelectric ceramic ignition. The embedded stove adopts the electronic pulse ignition method. When it is fired at a certain position, its ignition hit rate is high, generally 100%, but this There is a need to change the battery. The desktop stove adopts the piezoelectric ceramic ignition mode, and the success rate of the ignition is greatly affected by the environmental humidity. When the ignition is required, the switch needs to be held down to catch the fire.

  The safe use of the gas stove requires the installation of a flameout protection device. Currently, the commonly used flameout protection methods are mainly thermal, thermoelectric and photoelectric.

The thermal type is also called bimetal type. It uses the bimetal to expand and bend under the action of temperature. The bimetal is used as a sensor for safety protection. Under the action of temperature, the metal side with large expansion coefficient will have a coefficient of expansion. The small metal side is bent, and when the temperature is lost, the originally expanded and bent metal will slowly return to its original state.

  The thermoelectric flameout safety protection device is composed of two parts: a thermocouple and a solenoid valve. The thermoelectric type is made by using different thermoelectric potentials of different alloy materials under the action of temperature. The protection device uses a thermocouple as a thermal sensor and a cock The installation accuracy of the valve and the solenoid valve is high. Photoelectric type is also called ion induction type. The device utilizes gas to burn ions while burning and has unidirectional conductive properties. This type of security protection has now achieved AC induction and its reliability has been greatly improved.
