Description

Technical Field

[0001] This utility model relates to the field of oil pipe technology, and in particular to an explosion-proof marine control oil pipe. Background Technology

[0002] With the ongoing exploration and exploitation of offshore oil, natural gas, and other resources, the demand for offshore pipelines is increasing daily. The marine environment is extremely complex and challenging; the corrosiveness of seawater, immense water pressure, fluctuating temperatures, and the attachment of marine organisms all place stringent demands on the performance of offshore pipelines. To meet explosion-proof requirements, pipelines are typically manufactured using high-strength, corrosion-resistant materials such as stainless steel and alloy steel. These materials can withstand high pressure and harsh marine environments, preventing leaks or explosions due to corrosion or other causes. To further enhance the safety of explosion-proof marine control pipelines, a series of safety measures are required, such as the installation of safety valves, pressure gauges, and temperature sensors. These devices can monitor the pipeline's operating status in real time, promptly identifying and addressing potential safety hazards.

[0003] In existing technologies, most oil pipe connections are made using flanges. During operation, users need to pass multiple bolts through the flanges before connecting them, which is time-consuming and labor-intensive, reducing work efficiency.

[0004] Therefore, it is necessary to provide an explosion-proof marine control tubing to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1A schematic diagram of the structure of an explosion-proof marine control pipeline provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional structure of the threaded ring. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. An explosion-proof marine control pipeline includes: a pipe body 1, with flanges 2 fixedly installed at both ends of the pipe body 1;

[0023] Threaded ring 3, the threaded ring 3 is fixedly installed on one side of the two flanges 2 respectively, the outer side of the threaded ring 3 is threadedly connected to the threaded sleeve 31, and the outer side of the threaded sleeve 31 is provided with a connecting ring 35;

[0024] Rotating seat 4 is fixedly installed on the six circumferences of the outer side of the connecting ring 35. A connecting rod 41 is rotatably connected to the inner side of the rotating seat 4. A top rod 42 is fixedly installed on the top of the connecting rod 41. A positioning rod 43 is fixedly installed at one end of the bottom of the top rod 42.

[0025] The inner side of the connecting ring 35 is provided with a snap-fit ​​groove 36, and the top and bottom of the inner side of the snap-fit ​​groove 36 are provided with limit grooves 37.

[0026] A snap ring 32 is fixedly installed on the outer side of the threaded sleeve 31, and a limit plate 33 is fixedly installed on the top and bottom of the snap ring 32.

[0027] The snap ring 32 is slidably connected to the inner side of the snap groove 36, and the limiting plate 33 is slidably connected to the inner side of the limiting groove 37.

[0028] The inner side of the limiting groove 37 is provided with a ball bearing 34.

[0029] The ball bearing 34 is disposed on the outer surface of the limiting plate 33.

[0030] The working principle of the explosion-proof marine control oil pipe provided by this utility model is as follows:

[0031] In use, the user only needs to align the flanges 2 of two adjacent pipe bodies 1, and then rotate the connecting rod 41, causing the connecting rod 41 to move the top rod 42 until the top rod 42 moves to the top of the other flange 2, and the positioning rod 43 is positioned at the top of the threaded hole of the flange 2. Then, the user rotates the threaded sleeve 31, causing the threaded sleeve 31 to be threaded onto the outer side of the threaded ring 3, thereby causing the threaded sleeve 31 to move the snap ring 32 downward, and also causing the connecting ring 35 to move. At this time, the connecting ring 35 will cause the rotating seat 4 and the connecting rod 41 to move downward. When the connecting rod 41 moves downward, it will cause the top rod 42 and the positioning rod 43 to move, thereby causing the positioning rod 43 to be inserted into the inner side of the threaded hole, and then the two flanges 2 are locked together.

[0032] Compared with related technologies, the explosion-proof marine control tubing provided by this utility model has the following beneficial effects:

[0033] The threaded ring 3, threaded sleeve 31, snap ring 32, limiting plate 33, ball 34, connecting ring 35, snap groove 36, limiting groove 37, connecting rod 41, top rod 42, and positioning rod 43 work together to create a mechanism in which the threaded sleeve 31 moves the connecting rod 41 and top rod 42 downwards, allowing the positioning rod 43 to be inserted into the flange 2. This tightens the two flanges 2, eliminating the need for manual installation with bolts and making the process convenient, quick, and efficient.
