Natural gas is a kind of flammable and explosive gas, which is an important clean energy and has been widely used in many industries.Because of the flammable and explosive nature of natural gas, we must pay attention to the problem of natural gas leakage when using natural gas to prevent the occurrence of natural gas explosion accidents.
To prevent gas leak explosion accident, this needs us to install gas alarm to real-time detection of gas concentration, once reaches a certain concentration of gas leakage, gas alarm automatically audible and visual alarm to remind staff to take corresponding measures in time, to avoid the occurrence of major accidents.
Natural gas alarm as an important security facilities, alarm value is generally divided into one and two levels.Today we're going to talk about gas alarms why do we have two alarms?What are the benefits?
Level 1 alarm can realize the solenoid valve or exhaust fan when the equipment alarm.The second alarm device can realize double tube supervision, that is, when the natural gas alarm detects that the concentration of natural gas exceeds the first-level alarm value, it indicates that there is a phenomenon of natural gas leakage, but there is not much natural gas leakage, so when the first-level alarm chooses to start the exhaust fan, it can reduce the concentration of natural gas and ensure environmental safety.
When the concentration of natural gas reaches the second-level alarm value, it indicates that there is a large amount of natural gas leakage.At this time, the exhaust fan can not solve the problem, so choose to start the solenoid valve when the secondary alarm, directly cut off the gas pipeline.After the soap and water applied to the gas pipeline, there are bubbles generated in the place is the gas leakage point.Repair measures can be taken after leakage is found out.
