Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, and more specifically to a natural gas transmission leakage prevention device. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. 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. The safe operation of natural gas pipelines plays a very critical role in the production of oil and gas fields. The pipelines are buried underground all year round. During the operation of the pipelines, the natural gas pipelines leak due to external forces, corrosion or other reasons. If the leaked natural gas is not handled in time, it will cause major safety hazards.

[0003] Most of the existing disposal methods are to close the upstream and downstream valves, vent the natural gas, and weld the leaking points after venting. This disposal plan will lead to the shutdown of gas wells, the suspension of gas supply to downstream users, and the waste of natural gas resources. Therefore, there is an urgent need for a natural gas transmission leakage prevention device to clamp and repair the leaking natural gas pipeline in time to prevent the pipeline from continuing to leak.
