Technical Field

[0001] The utility model relates to the technical field of natural gas analyzers, in particular to a natural gas analyzer with good airtightness. Background Art

[0002] A natural gas analyzer is an instrument specifically used to analyze the chemical composition, components, concentration, etc. of natural gas samples. These analyses help determine the quality, suitability, and compliance of natural gas for specific purposes. It is widely used in different links such as natural gas exploration, production, transportation, storage, and use. At the same time, the natural gas analyzer should have a high degree of sealing and accuracy, so a natural gas analyzer with good sealing is needed to analyze natural gas.

[0003] When conducting detection and analysis of natural gas, it is necessary to connect the natural gas inlet pipe with the air inlet in the natural gas analyzer to facilitate the transportation of natural gas to the natural gas analyzer for analysis. When connecting the natural gas inlet pipe and the air inlet of the natural gas analyzer, the air inlet pipe is mostly embedded in a plug-in manner, but the plug-in installation method is not strong enough and can easily cause the air inlet pipe to fall off the air inlet when subjected to external force, thereby creating a danger. Therefore, technical personnel in this field provide a natural gas analyzer with good sealing properties to solve the problems raised in the above background technology. Utility Model Content
