How long does it take for a gas leak to cause a violent explosion? The answer is 20 minutes.
Many people think it takes hours from the moment the gas starts leaking to the moment it meets a spark and explodes, but scientific tests by the fire department have proved that the process takes only 20 minutes.
The researchers set up a makeshift four-square-metre cabin with a gas range and a domestic gas tank. Then the experimenters simulated gas hose leak, gas leakage, 20 minutes later, the surrounding gas concentration can be smelled. The experimenters then lit the fire and the house exploded with a force that lifted it more than half a metre into the air, shattering all the glass, knocking out a window and cracking a wall.
What is combustible gas detector
Combustible gas sensor: A combustible gas sensor is a detector that responds to the concentration of one or more combustible gases.
The intelligent, durable and easy to operate flammable gas sensor is designed to detect changes in the concentration of flammable alkanes at the lower explosive limit from 0 to 100%. The detector uses a patented “small pluggable” infrared optical sensor. Infrared sensors are characterized by long periods of stability and minimal periodic maintenance. Infrared gas sensors are an excellent alternative to conventional catalytic combustion sensors in some measurement environments.
Causes of gas leakage
The harm of gas explosion is so serious that the first thing to prevent gas explosion is to prevent gas leakage. From the factors causing gas leakage, hose problems account for 44%, hose aging, not connected, falling off is the primary factor leading to gas leakage; Forget to close or not completely close the valve accounted for 15%; Improper replacement or maintenance of liquefied gas tank leakage causes accounted for 14%. The above constitute the “three SINS” of gas leakage and gas explosion.
If we can monitor the gas leakage in the first time and solve it in the fastest time. We can prevent the gas explosion from happening, so that we can not only prevent the house from becoming a ruin, but also avoid serious casualties.
1 second warning, prevent gas explosion
In the past, we mainly rely on manpower to check gas leakage, which is difficult to work 24 hours a day, and many hidden dangers can not be monitored by the naked eye and nose. With the development of science and technology, it has become an irresistible trend to use Internet of things early warning technology to prevent gas explosion.
Take JXCT’s independently developed combustible gas sensor as an example. When it detects gas concentration in the air beyond the normal range. It immediately sends the signal to iot base stations and early warning platforms. It takes only one second for the platform to send a message via phone or other means. So users can be notified immediately even if they are not at home.
A one-second warning is especially valuable in the 20 minutes it takes for a gas leak to trigger an explosion. At the first time of receiving the danger notice, the user can immediately make the necessary hidden trouble removal work. In serious cases, can also call the gas emergency repair telephone or immediately alarm. To prevent serious explosion accidents caused by gas leakage.
In addition to combustible gas sensors, JXCT also introduces smoke, toxic gas and other types of sensors. Which can carry out real-time monitoring and second-level warning of smoke concentration, wire temperature, current size and so on.
JXCT gas sensor helps protect the safety of the entire home and its members.
