Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection, and in particular to an oil pipe connection device. Background Technology

[0002] In oilfields where oil extraction is carried out, the oil transportation system is extremely important. The oil transportation system consists of interconnected oil pipelines arranged in an interlocking manner. Oil pipelines are generally designed in multi-section configurations, with connecting structures used to link different sections of the pipeline together.

[0003] Currently, the connection structure of oil pipelines generally uses ordinary connecting sleeves or pipe clamps. The connecting sleeves or pipe clamps are fixed to the oil pipeline, and then the two connecting sleeves are fixed together with bolts. This connection method is relatively simple, but the sealing effect at the connection is not particularly good. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing an oil pipe connection device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A tubing connection device includes two clamping assemblies and a connecting sealing assembly. The two clamping assemblies are respectively clamped on two pipes to be connected, and the connecting sealing assembly is disposed between the mating end faces of the two pipes to be connected. The connecting sealing assembly is connected to the two clamping assemblies through a connecting rod assembly.

[0007] Each clamping assembly includes two semi-circular clamping plates, with connecting lugs at both ends of the semi-circular clamping plates. The two semi-circular clamping plates are clamped outside the pipe and the corresponding connecting lugs are fixedly connected by fastening bolts and fastening nuts. A first connecting hole is passed through the semi-circular clamping plate.

[0008] The connecting sealing assembly includes a plug tube, with both ends of the plug tube inserted into the two pipes to be connected. The outer diameter of the plug tube is the same as the inner diameter of the pipe. A connecting ring seat is provided in the middle of the outer wall of the plug tube, and a second connecting hole is provided through the connecting ring seat. The second connecting hole is set in correspondence with the first connecting hole.

[0009] The connecting rod assembly includes a connecting rod that passes through a first connecting hole and a second connecting hole, with locking nuts screwed onto the outer ends of the semi-annular clamping plate at both ends of the connecting rod.

[0010] The portion of the connector that meets the inner walls of the two pipes is provided with annular grooves, and a sealing ring is provided inside the annular grooves.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a connecting sealing component to connect two pipes, avoiding the situation of poor sealing caused by simply using the pipe end face to connect. It uses a plug pipe to connect with the inner wall of the pipe, which increases the sealing area. It uses a sealing ring to achieve a tighter seal. After installation, the two pipes are fastened with two clamping components to complete the overall connection. Attached Figure Description
