[0002] Natural gas refers to a type of combustible gas existing in nature. It is a fossil fuel, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gasfield gas, mud volcano gas, coalbed methane, and biogenic gas, etc.). The definition of "natural gas" that people have long used is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. In petroleum geology, it usually refers to oilfield gas and gasfield gas. Its composition is mainly hydrocarbons and contains non-hydrocarbon gases, so it burns to produce yellow or blue flames.

[0003] Pressure detection alarms are usually installed on natural gas transmission pipelines to monitor pipeline pressure. When the pressure in the pipeline exceeds the range, timely maintenance is required. However, most existing pressure detection alarms are fixed with a large number of bolts, which makes it difficult to disassemble and assemble the pressure detection alarms from the pipeline.
