Safety alarms Ultra-thin gas stoves include bimetal temperature probes, control switches, alarm boxes and limiters. When the cooker is ventilated, the control switch is turned on, the alarm device is in the working state, and because the probe is heated, the alarm circuit is turned off by the bimetal deformation control, and when the accidental flameout occurs, the bimetal is restored, and the alarm circuit is turned on. An alarm signal such as sound and light is emitted. The safety alarm ultra-thin gas stove has the advantages of simple structure, convenient use and high reliability.
Safety alarm ultra-thin gas stove is a gas leak detection alarm instrument. When the gas in the industrial environment leaks, the safety alarm ultra-thin gas stove detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the safety alarm ultra-thin gas stove will send an alarm signal to remind the staff to take safety measures. The gas leak alarm is a very important gas safety device, and it is the last protection for safe use of city gas. The gas leak alarm detects the low concentration combustible gas in the surrounding environment through the gas sensor, and transmits the detection signal to the controller or the control circuit through the sampling circuit through the sampling circuit, when the concentration of the combustible gas exceeds the controller or the control circuit. At a fixed value, the controller issues an alarm signal through an actuator or an execution circuit or performs an action such as closing the gas valve. Sensors for detecting combustible gases of combustible gases are mainly oxide semiconductor type, catalytic combustion type, hot line type gas sensors, and a small number of other types, such as chemical battery type sensors. These sensors generate chemical or electrochemical reactions on the sensor surface by adsorption to flammable gases in the surrounding environment, resulting in changes in the electrical and physical properties of the sensor.
The gas leak alarm can be functionally divided into a leak with only the leak alarm function and a test that can indicate the detected gas concentration and has an alarm function; it can be classified into a civil gas leak alarm and commercial use from the place of use. Civil use is usually an independent gas used in residential buildings, and its function is relatively simple; commercial use mainly uses gas transportation, storage places, gas stove leak detection, use of gas and factories and public places that may have gas leak alarms. The city gas code stipulates that the gas room in the basement, semi-basement, closed space on the ground, the pipe well of the building, and the closed meter room shall be installed with gas. Civil gas leak alarms are also recommended for building and gas related codes and regulations.
