Description

Technical Field

[0001] The utility model relates to the technical field of natural gas plugging auxiliary equipment, in particular to a natural gas pipeline leakage plugging device. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas (including associated gas produced by oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise user. It is also called a gas transmission pipeline. It is the main way to transport natural gas in large quantities on land. Natural gas pipelines account for about half of the total length of pipelines in the world. The main reason why natural gas pipelines need leak plugging devices is safety considerations. Natural gas is a flammable and explosive gas. Once a leak occurs, it will not only cause a waste of resources, but may also cause serious accidents such as fire and explosion, posing a huge threat to people's lives and property. Therefore, installing a leak plugging device can timely and effectively plug the leak point to prevent the expansion of the accident and The current natural gas plugging equipment will add rubber pads between the equipment and the pipeline to ensure the sealing effect when implementing leak plugging. However, as time goes by, these rubber pads will age significantly faster without proper protection. This aging phenomenon may cause the risk of secondary leakage and pose a potential threat to the safe transportation of natural gas. Therefore, it is particularly urgent to solve this problem. We must take effective measures to extend the service life of the rubber pads and ensure the long-term stability and safety of the plugging equipment. For the above problems, there may already be technical means to solve them in the existing technology, but this case wants to provide an alternative or replacement technical solution.
