Safety knowledge：You must know whether there is a gas leak

Nowadays, with the advantages of fast heat energy and less pollution, gas has entered thousands of households. However, due to some residents' low safety awareness and wrong gas habits, gas leakage often occurs, resulting in fire, explosion and poisoning accidents.
 
So, in the process of daily gas use, what are the methods to judge whether the gas leaks? Let's have a look!
 
1、 Smell
Natural gas itself is colorless and tasteless. In order to ensure the safety of transmission and use and find gas leakage in time, household gas will be odorized before entering residents' homes to make it smell like rotten eggs.
 
If you smell rotten eggs at home, it is likely to be a gas leak.
 
2、 Gas check meter
Turn off the gas stove at home. When there is no gas at all, if the number in the last red box of the gas meter moves around, it can be judged that there is a gas leakage.
 
3、 Listen to the sound
In the process of using fuel gas, if you hear the "bare" sound, it may be fuel gas leakage, which should be paid attention to immediately.
 
4、 Bubbling method
When it is suspected that there is gas leakage, soapy water can be used to smear on the places where there may be gas leakage (such as rubber hose, interface, pipeline, plug valve, etc.). If small bubbles appear and increase continuously, it indicates that there is gas leakage in this part.
 
5、 Installation of domestic gas alarm
Domestic gas alarm is a professional instrument for detecting gas leakage concentration, which can be detected in real time. When the gas leakage concentration reaches or exceeds the preset value, it will immediately send out audible and visual alarm signals to effectively prevent disasters and accidents.
 
At present, the installation of domestic gas alarm is the most scientific and effective means to prevent gas leakage.
 
Chicheng HD2000 household gas detector adopts high-sensitivity sensor, which can continuously detect the leakage concentration of combustible gas for 24 hours, and send out sound and light early warning signals in time. In addition, HD2000 household gas detector can also link solenoid valve, manipulator, exhaust fan and other equipment to prevent fire and explosion accidents caused by gas leakage.

In addition to installing domestic gas alarm, users can also effectively prevent gas leakage through the following methods.
 
01. Install gas emergency cut-off device
The gas emergency cut-off devices commonly used in residents' homes are generally solenoid valves and manipulators.
Solenoid valve and manipulator are generally used together with domestic gas alarm. When gas leakage is detected and the alarm alarms, the solenoid valve and manipulator can also be linked to close the gas valve and cut off the gas source to further protect the safety of gas use.
 
 
 
02. Use gas stove with flameout device
According to the standard requirements of commercial gas burning appliances implemented on March 1, 2019, each burner of all types of commercial gas appliances must be equipped with flameout protection device.
 
 
 
03. Develop a good habit of using gas
When using gas, residents should pay attention to opening windows for ventilation, develop good gas habits, ensure that the fire does not leave people, use high-temperature resistant metal bellows that are not easy to fall off, and pay attention to gas safety all the time.
 
At the end of the year, the frequency of gas use has entered the peak. Install domestic gas alarm devices in time to protect family safety! Come and join us!
