Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, and in particular to a natural gas pipeline 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. Natural gas is stored in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas and biogenic gas, etc. A small amount also comes from coal seams. The main use of natural gas is as fuel. It can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and alkanes produced from natural gas are important raw materials for modern industry.

[0003] The authorization announcement number is: CN211624488U. The new patent document, a leakage prevention device for installing a natural gas pipeline, includes a pipeline body, an upper clamping ring, and a sealing tube. The upper clamping ring is matched with the outer end face of the pipeline body, and the sealing tube thread is set at the left end face and the right end face of the upper clamping ring. Through the layout and matching arrangement of the reinforcement tube, the upper clamping ring, and the lower clamping ring, the pipeline body can be reinforced, which can ensure the impact resistance of the pipeline body. At the same time, by utilizing the layout arrangement of its support rod, telescopic spring, block, shock-absorbing bubble and anti-slip thorn, the impact resistance effect of its pipeline body can be further improved. Due to the provision of a sealing tube, a sealing gasket, an upper clamping ring, a lower clamping ring and a reinforcement tube, the left and right sides of the pipeline body can be sealed and protected. Finally, through the layout arrangement of its threaded fixings and limiting nuts, the upper clamping ring, the lower clamping ring, the reinforcement tube and the sealing tube can be fixed and limited.

[0004] The device can seal and protect the left and right sides of the pipeline body by providing a sealing tube, a sealing gasket, an upper clamping ring, a lower clamping ring and a reinforcement tube. Finally, through the layout of its threaded fixings and limiting nuts, the upper clamping ring, the lower clamping ring, the reinforcement tube and the sealing tube can be fixed and limited. However, when natural gas pipelines are usually connected, flange connections are generally used and multiple bolts are used to fix them. The structure is cumbersome. When the natural gas pipeline leaks, the natural gas generally leaks from the pipeline connection. However, when leaking, it is not easy for workers to disassemble it, which will endanger human health.
