Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection and alarm, in particular to a combustible gas detection and alarm device. Background Art
[0002] Combustible gases are substances that can ignite and are in a gaseous state at normal temperature and pressure. Examples include hydrogen, acetylene, ethylene, ammonia, and hydrogen sulfide. Combustible gases exhibit the general properties of gases. A single-component combustible gas is called a single gas; a mixture of two or more combustible gases is called a mixed combustible gas. Combustible gases mixed in a corresponding combustion-supporting medium in a specific proportion can cause combustion or explosion when ignited by an ignition source. Combustible gases are ejected from a nozzle at a specific flow rate, and their combustion rate is determined by the diffusion rate between the combustible gas and air.
[0003] The heat-generating properties of combustible gases are widely used in society, but due to their rapid diffusion in the air, ignition can easily cause large-scale or even explosions. However, combustible gas leaks are often difficult to detect, and by the time they occur, significant leaks have already occurred.
[0004] Therefore, it is necessary to design a combustible gas detection alarm device. Utility Model Content
