Description

Technical Field

[0001] This utility model relates to the field of oil and gas transportation technology, and in particular to a sealing connection device for oil and gas transportation pipelines. Background Technology

[0002] Chinese patent document CN207935636U discloses a well-sealed pipeline connector. This utility model relates to a well-sealed pipeline connector, including a pipe, a flange, and bolts, and also includes an anti-corrosion sealing structure. The anti-corrosion sealing structure includes a first protective cover, a second protective cover, and a locking cover. The first and second protective covers are congruent semi-circular covers, and rectangular protrusions are vertically fixed at the upper and lower edges. Circular grooves are formed on the opposite outer walls of the pair of rectangular protrusions at the upper end. A locking groove is formed on the inner wall of the rectangular protrusion at the lower end of the first protective cover, and locking teeth are fixed on the inner wall of the rectangular protrusion at the lower end of the second protective cover. This utility model can effectively solve the problem that existing flange connectors lack protective structures, are severely corroded by the natural environment, and are prone to oil leaks.

[0003] The aforementioned device is not designed to protect the pipe connections, and external impacts may cause the connections to loosen, leading to pipe slippage. This issue needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing connection device for oil and gas transmission pipelines, which can solve the problem that the above-mentioned devices cannot protect the pipeline connection when they are constructed, and external collisions may cause the connection to loosen, resulting in the pipeline slipping.

The first threaded ring is provided inside the first connecting ring, and the fixing frame is fixedly connected to the top of the first threaded ring. The sealing ring is fixedly connected inside the fixing frame. This mechanism can be connected and assembled with the assembly mechanism to form a docking compartment, which can connect the first delivery pipe and the second delivery pipe to prevent oil and gas leakage. On the other hand, the accumulated stacking of parts in this mechanism can dampen the connection between the first delivery pipe and the second delivery pipe, avoiding loosening of the connection and slippage of the pipe due to external impact.

[0007] Preferably, the assembly mechanism further includes a second threaded ring and a housing. The second threaded ring is provided inside the second connecting ring, and the housing is snapped onto the outer wall of the second threaded ring. The housing is fitted with a second conveying pipe. This mechanism can wrap the connection of the outer wall of the second conveying pipe and provide external protection for the connection, thereby mitigating the vibration caused by the impact and preventing oil and gas leakage.

[0008] Preferably, the first connecting ring has a first internal thread groove, the first threaded ring is threaded into the first internal thread groove, and the first connecting ring is threaded into the first threaded ring.

[0009] Preferably, the sealing ring has an H-shaped groove, and the sleeve ring is rotatably connected to the H-shaped groove, thus the sealing ring and the sleeve ring are rotatably connected.
