Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion pipelines, in particular to an anti-corrosion pipeline with a sealing structure. Background Art

[0002] Pipeline anti-corrosion is a protective technology that prevents pipelines from being corroded by soil, air and conveying media (oil, natural gas, etc.). Most pipelines that transport oil and gas are in complex soil environments, and the media they transport are also corrosive. Therefore, both the inner and outer walls of the pipelines may be corroded. With the extensive application of anti-corrosion pipelines, the anti-corrosion performance has been greatly improved. The inner and outer surfaces of metal pipelines are coated with inner lining and outer coating, which greatly reduces the corrosion problem. However, the anti-corrosion sealing effect at the connection between the two pipelines is not ideal.

[0003] After searching, it is found that the Chinese patent "A Sealing Structure for Corrosion-Resistant Pipes" with the publication number "CN211289106U" solves the above-mentioned problem through the plug-in sealing installation of the first sealing seat and the second sealing seat, which can not only effectively prevent the leakage of the medium in the pipe, but also save a lot of installation time and reduce labor costs. However, when the device is sealing, the sealing block and the sealing plate extend into the interior of the pipe, which will cause a gap at the interface of the two pipes, increasing the probability of leakage at the interface. At the same time, the sealing plate entering the interior of the pipe will also reduce the cross-section of the inner wall of the pipe, reducing the transportation efficiency of the pipe.

[0004] Therefore, an anti-corrosion pipeline with a sealing structure is proposed to solve the above problems. Utility Model Content

[0008] Preferably, a secondary ring is fixedly connected to the other side of the connecting ring, and a ring-distributed clamping plate is fixedly connected to the surface of the secondary ring, the surface of the clamping plate contacts the inner wall of the sealing seat, and the inner wall of the sealing seat is fixedly connected to an annular plate clamped with the clamping plate, and a chamfer is provided on the side of the annular plate close to the connecting ring, and the shape of the clamping plate is arc-shaped, and the clamping plate is an elastic stainless steel member. The connecting ring will drive the secondary ring to be inserted into the interior of the sealing seat, and at this time, the clamping plate made of elastic stainless steel will contact the annular plate and deform under the action of the chamfer on the annular plate. After the clamping plate and the annular plate are misaligned, the clamping plate is reset and clamped with the annular plate, thereby improving the connection strength between the connecting ring and the connecting groove, improving the connection stability of the first pipeline and the second pipeline, and reducing the probability of leakage between the first pipeline and the second pipeline.
