Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, in particular to a natural gas sampling device. Background Art

[0002] In the prior art, natural gas refers to a type of combustible gas existing in nature. It is a fossil fuel and includes 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 has long been commonly used is a narrow definition from an energy perspective, referring to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in 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 a yellow or blue flame. In the prior art, when sampling natural gas inside a pipeline with a low internal pressure, sampling is often done manually by staff, which has poor stability and is prone to leakage.

[0003] Therefore, the present application proposes a natural gas sampling device to solve the above-mentioned problems. Utility Model Content
