Description

Technical Field

[0001] This utility model relates to the technical field of gas detection devices, and in particular to a combustible gas alarm metering and detection device. Background Technology

[0002] Combustible gases are substances that can be ignited and exist in a gaseous state at normal temperature and pressure. Examples include hydrogen, acetylene, ethylene, ammonia, and hydrogen sulfide. Combustible gases possess the general characteristics of gases. A combustible gas consisting of only one component is called a single gas; a mixture of two or more combustible gases is called a mixed combustible gas. When combustible gases are mixed in a certain proportion in a suitable combustion-supporting medium, they can ignite or explode under the action of an ignition source. Combustible gases are injected from nozzles at a certain flow rate, and their combustion rate is determined by the diffusion rate between the combustible gas and air.

[0003] Currently, conventional combustible gas metering and detection devices are directly installed above the pipeline and exposed to the environment, making them easily susceptible to external environmental influences, which can damage the devices. Additionally, leaks can occur at the connection between the measuring pipeline and the gas transmission pipeline due to damaged gaskets, thus affecting the detection results.

[0004] Therefore, those skilled in the art have provided a combustible gas alarm metering and detection device to solve the problems mentioned in the background art. Utility Model Content
