Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas pipelines, in particular to a connecting assembly for oil and gas pipelines. Background Art

[0002] Oil and natural gas are important energy sources in my country. When transporting these energy sources, the transportation devices used generally choose to transport them through pipelines. By connecting pipes one by one, they are assembled into pipelines for transporting oil and gas.

[0003] There is a kind of oil and gas pipeline connector that is easy to install (its authorization announcement number is: CN218719455U), which rotates a plurality of fixed blocks. When the plurality of fixed blocks move to the two sides of the two pipelines respectively, the external threaded barrel is rotated forward, and the plurality of fixed rods that are close to each other drive the plurality of fixed blocks to approach each other through the rotating rod and then contact the two pipelines, so that the two pipelines drive the sealing assembly to be connected in the connecting pipe, so that the user only needs to rotate the external threaded barrel to quickly install the two pipelines together; however, there are some shortcomings in the actual operation process: it is necessary to rotate and adjust the plurality of fixed blocks at both ends of the external threaded barrel in turn to contact and fit on the pipeline, and the operation is relatively cumbersome. Secondly, since the plurality of fixed blocks are distributed in a circular array, when one fixed block is rotated and adjusted and the next fixed block is rotated and adjusted, the previous fixed block is easily deflected under the action of gravity and then separated from the pipeline, which is inconvenient to operate. Therefore, we propose a connection assembly for oil and gas pipelines to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a connection assembly for oil and gas pipelines to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the two internal threads in the threaded barrel are symmetrically arranged, and the thread rotation directions of the two internal threads are opposite. Since the thread rotation directions of the two internal threads in the threaded barrel are opposite, when the threaded barrel is rotated, the two external threaded barrels sleeved outside the connecting barrel can be driven to approach each other.

[0009] Preferably, the number of the externally threaded barrels is set to two, and the two externally threaded barrels are respectively sleeved on the two ends of the connecting barrel, so that the two externally threaded barrels sleeved outside the connecting barrel can move on the outer surface of the connecting barrel.

[0010] Preferably, the elastic connection mechanism includes a mounting block and a spring, and the mounting blocks are movably installed in the two corresponding mounting grooves, one side of the two mounting blocks is fixedly connected to the arc-shaped positioning clamping plate, one end of the spring is fixedly installed on the top side of the two mounting blocks, and the other ends of the two springs are respectively fixedly installed on the top side inner walls of the corresponding mounting grooves. The elastic connection mechanism is used to facilitate the movable adjustment of the corresponding arc-shaped positioning clamping plates, so that one end of the oil and gas pipeline body can be easily inserted into the pipe groove at one end of the connecting tube.

[0011] Preferably, the number of the arc-shaped positioning clamps is set to four, and the corresponding two arc-shaped positioning clamps are respectively inserted into the top and bottom of the same oil and gas pipeline body, so that the two sets of arc-shaped positioning clamps at both ends of the connecting tube are respectively clamped at the top and bottom of the two oil and gas pipeline bodies.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

When the two sets of arc-shaped positioning clamps at both ends of the connection barrel are respectively clamped at the top and bottom of the two oil and gas pipeline bodies, by rotating the threaded barrel, the two internal threads in the threaded barrel have opposite thread rotation directions, thereby driving the two externally threaded barrels sleeved on the outside of the connection barrel to approach each other, making it easy to tightly install the two oil and gas pipeline bodies at the two ends of the connection barrel, thereby completing the connection and installation of the two oil and gas pipeline bodies, and the operation is simple and fast.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4 A connection assembly for oil and gas pipelines includes a connection tube 1 and an oil and gas pipeline body 2. Both ends of the connection tube 1 are provided with pipe grooves 3. One end of the two oil and gas pipeline bodies 2 is respectively inserted into the corresponding pipe grooves 3. The outer surface of the connection tube 1 is provided with a rotation groove 5. A threaded rotating tube 6 is rotatably installed in the rotation groove 5. Two internal threads 7 are respectively provided in the threaded rotating tube 6. External threaded tubes 8 are threadedly installed in the two internal threads 7. A plurality of installation grooves 9 are respectively provided on one side of the external threaded tube 8. The same arc-shaped positioning clamp 12 is installed in the corresponding two installation grooves 9 through an elastic connection mechanism. The elastic connection The mechanism includes a mounting block 10 and a spring 11. The mounting blocks 10 are movably installed in the two corresponding mounting grooves 9. One side of the two mounting blocks 10 is fixedly connected to the arc-shaped positioning clamping plate 12. One end of the spring 11 is fixedly installed on the top side of the two mounting blocks 10. The other ends of the two springs 11 are respectively fixedly installed on the top inner wall of the corresponding mounting groove 9. The elastic connection mechanism is used to facilitate the movable adjustment of the corresponding arc-shaped positioning clamping plate 12, so that one end of the oil and gas pipeline body 2 is conveniently inserted into the pipe groove 3 at one end of the connecting tube 1; the arc-shaped positioning clamping plate 12 is inserted on one side of the oil and gas pipeline body 2.

[0021] Furthermore, a sealing ring 4 is provided on the inner wall of the pipe groove 3, and one end of the oil and gas pipeline body 2 is sealedly connected to the sealing ring 4, so as to ensure the sealing of the connection between the two oil and gas pipeline bodies 2 and reduce the occurrence of oil and gas leakage.

[0022] Furthermore, the two internal threads 7 in the threaded barrel 6 are symmetrically arranged, and the thread rotation directions of the two internal threads 7 are opposite. Since the thread rotation directions of the two internal threads 7 in the threaded barrel 6 are opposite, when the threaded barrel 6 is rotated, the two external threaded barrels 8 sleeved on the outside of the connecting barrel 1 can be driven to approach each other.

[0023] Furthermore, the number of the externally threaded barrels 8 is set to two, and the two externally threaded barrels 8 are respectively sleeved on the two ends of the connecting barrel 1, so that the two externally threaded barrels 8 sleeved outside the connecting barrel 1 can move on the outer surface of the connecting barrel 1.

[0024] Furthermore, the number of arc-shaped positioning clamps 12 is set to four, and the corresponding two arc-shaped positioning clamps 12 are respectively inserted into the top and bottom of the same oil and gas pipeline body 2, so that the two sets of arc-shaped positioning clamps 12 at both ends of the connecting tube 1 are respectively clamped at the top and bottom of the two oil and gas pipeline bodies 2.

[0025] During use: When connecting and installing two oil and gas pipeline bodies 2, the staff adjusts the two arc-shaped positioning clamps 12 to move away from each other, so that the two mounting blocks 10 on one side of the arc-shaped positioning clamps 12 slide in the corresponding mounting grooves 9. At this time, the two sets of springs 11 are deformed and compressed by force, and then one end of the oil and gas pipeline body 2 is inserted into the pipe groove 3 at one end of the connecting tube 1, so that one end of the oil and gas pipeline body 2 fits on the sealing ring 4, and then the two arc-shaped positioning clamps 12 are loosened. Under the elastic force of the two sets of springs 11, the two arc-shaped positioning clamps 12 are moved closer to each other and inserted into the oil and gas pipeline body 2. The top and bottom of the pipeline body 2 are repeated to insert and clamp another oil and gas pipeline body 2 on the other end of the connecting tube 1. Then, by adjusting the threaded rotating cylinder 6 to rotate in the rotating groove 5 on the outer surface of the connecting tube 1, since the thread rotation directions of the two internal threads 7 in the threaded rotating cylinder 6 are opposite, the two external threaded cylinders 8 sleeved on the outside of the connecting tube 1 are driven to approach each other, and the two sets of arc-shaped positioning clamps 12 at both ends of the connecting tube 1 are driven to approach each other, so that the two oil and gas pipeline bodies 2 are tightly installed at the two ends of the connecting tube 1, thereby completing the connection and installation of the two oil and gas pipeline bodies 2, and the operation is simple and fast.
