Natural gas is a clean and efficient combustible gas. Its emergence replaces the air pollution caused by coal combustion and greatly improves the environmental quality. However, in the confined space, once the natural gas leaks, it is prone to explosion and fire after mixing with air. Therefore, the prevention and disposal of natural gas leakage is a work that every gas user should attach great importance to. It is necessary to install gas alarm.
Don't underestimate the gas alarm. It's very useful! This is a gas leakage detection and alarm instrument. When it is detected that the gas concentration exceeds the safety setting value, an audible and visual alarm will be sent out to remind people to take protective measures. Why install such a device? Because most of the gas outlets of gas meters and furnaces are connected by hoses, if they have been used for about 3 years, there is a risk of gas leakage due to weathering and lampblack erosion. Moreover, many people do not have the habit of turning off the gas meter valve when cooking. The above situation has brought many risks to the use of gas.
Many families have installed gas alarms for gas safety, and sometimes the gas alarm keeps ringing when there is no gas leakage. There are many reasons for this situation, which need to be analyzed in detail.
The gas alarm keeps ringing, which may be because the gas concentration reaches the alarm value or false alarm. The main reasons are as follows:
1. The gas leaked.
2. Combustion produces a lot of waste gas in the house.
3. There are some open volatile gases in the room, such as hair gel, insecticide and so on.
4. The gas alarm has failed.
When the gas alarm goes off, don't be careless. If we smell the smell of gas at the same time, users should immediately turn off the gas source and evacuate their families for window ventilation. When they evacuate to the outdoor safety zone, call the gas company for repair and ask the master to check on site. It's safer. Remember not to make calls, switch lights, light lighters and other behaviors prone to sparks in the room full of natural gas.
If you don't smell the obvious smell of gas, you should turn off the gas when judging whether it is a false alarm, brush soapy water on the gas hose and all connections for leakage, and if bubbles are found, it is air leakage.
If no gas leakage is found, beer and other drinks containing a large amount of other gases are not heated, and cooking wine, vinegar and other spices are not used, but the alarm continues to alarm, it can be preliminarily judged as the problem of gas alarm. At this time, if you want to judge whether the alarm works normally, you can check the self-test button on the alarm, and press it after recognition to give an audible and visual alarm.
If there is no problem with the self inspection of the gas alarm, the great possibility is that the gas alarm gives a false alarm. Such a situation is likely to be related to factors such as excessive opening of steam and gas during cooking, insufficient combustion, or the gas alarm is too close to the stove, and it is covered with a certain amount of dust and oil fume.
