The large-scale application of combustible gases in daily life has replaced the air pollution caused by coal combustion and greatly improved the environmental quality. However, in the confined space, once the gas leaks, it is prone to explosion and fire after mixing with air. Therefore, the installation of gas alarm, prevention and disposal of gas leakage is the work that every gas consuming family should attach great importance to.
The key to prevent and deal with gas leakage is to know whether there is gas leakage in time. For this problem, some people have played a sensitive sense of smell and artificial recognition; Someone has learned to apply soapy water and recognize the technology; Others chose to install gas alarm and scientific and technological identification.
Gas alarm is a very important gas safety equipment. It is the last "defense line" for the safe use of urban gas. The gas alarm detects the low concentration combustible gas in the surrounding environment through the gas sensor, and transmits the detection signal to the controller or control circuit with analog or digital quantity through the sampling circuit. When the combustible gas concentration exceeds the value set in the controller or control circuit, the controller sends an alarm signal or closes the gas valve through the actuator or actuator circuit.
If a gas alarm is installed at home, when there is a gas leakage and the concentration exceeds the set value, the alarm will be triggered and send out audible and visual alarm information. The main engine can be connected to the alarm center automatically, and the safety of personnel and property can be ensured if the alarm can be closed at the same time.
