A connector for oil pipelines with self-healing function

Abstract

The present invention discloses a connector for a petroleum pipeline with a self-repairing function, which belongs to the field of pipeline sealing. The connector for a petroleum pipeline with a self-repairing function comprises a first pipeline and a second pipeline. When the first pipeline and the second pipeline are clamped together to form a long pipeline, two arc-shaped clamping rings are first formed into a seal to seal and protect the connection between the first pipeline and the second pipeline. When an oil leak occurs between the first pipeline and the second pipeline, the oil-soluble inner ball is dissolved and the repair agent is filled in the inner ring to partially seal the oil leak, thereby avoiding the risk of large-scale oil leakage without timely repair causing losses to the enterprise. Compared with the existing sensor detection method, this method can not only preliminarily seal the connection between the first pipeline and the second pipeline, but also can repair and monitor the oil leak points that may occur therebetween, which is beneficial to ensuring the normal transportation of oil.

Description

Technical Field

[0001] The present invention relates to the field of pipeline sealing, and more particularly to a connector for a petroleum pipeline with a self-repairing function. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons in naturally occurring forms. Petroleum can be categorized into crude oil, natural gas, natural gas liquids, and natural tar, but the term "petroleum" is often used to define crude oil.

[0003] Oil transportation in oil extraction or testing equipment is generally completed through pipelines. The pipeline lines are often connected by several short pipelines to form a complete long pipeline. The joints between the pipelines generally need to be regularly tested for sealing using induction equipment with built-in sensors to avoid oil leaks.

[0004] However, this type of sensing device with a built-in sensor can only detect the pipeline connection and cannot repair the pipeline in time. Once a pipeline leaks, the short connecting flange cannot prevent the leaked oil from flowing everywhere before the maintenance personnel arrive at the site. Therefore, an oil pipeline seal with both repair and monitoring functions can be designed to solve this problem. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] In response to the problems existing in the prior art, the purpose of the present invention is to provide a connector for oil pipelines with a self-repairing function, which can achieve that when the first pipeline and the second pipeline are clamped together to form a long pipeline, the two arc-shaped clamping rings are first threadedly connected through the side ears of the side thereof to form a seal to seal and protect the connection between the first pipeline and the second pipeline. When an oil leak occurs between the first pipeline and the second pipeline, the oil at the leak point flows to the oil-soluble inner ball on the inner side of the repair agent filling inner ring, the oil-soluble inner ball is dissolved, and the repair agent in the repair agent filling inner ring flows out to partially seal the oil leak point, thereby avoiding the risk of large-scale oil leakage and failure to repair in time to cause corporate losses. Compared with the existing sensor detection method, this method can not only preliminarily seal the connection between the first pipeline and the second pipeline and strengthen the connection force, but also temporarily self-repair the oil leak points that may occur in the middle, effectively delaying the amount of oil leaking from the pipeline, gaining valuable repair time for maintenance personnel, and ensuring the normal transportation of oil.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] The pipe is connected to the second pipe by a screw thread, and the pipe is connected to the flange of the flange of the flange of the second pipe by a screw thread, and the pipe is connected to the flange of the flange of the second pipe by a screw thread. The repair agent cooperates with the connection between the first pipe and the second pipe. When the first pipe and the second pipe are clamped together to form a long pipe, the two arc-shaped clamping rings are first threadedly connected through the side ears thereof to form a seal to seal and protect the connection between the first pipe and the second pipe. When an oil leak occurs between the first pipe and the second pipe, the oil at the leak point flows to the oil-soluble inner ball on the inner side of the repair agent filling inner ring, the oil-soluble inner ball is dissolved and the repair agent in the repair agent filling inner ring flows out to partially block the oil leak point, avoiding the risk of large-scale oil leakage and failure to repair in time to cause corporate losses. Compared with the existing sensor detection method, this method can not only preliminarily seal the connection between the first pipe and the second pipe and strengthen the connection force, but also temporarily self-repair the oil leak points that may occur in the middle, effectively delaying the amount of oil leaking from the pipeline, gaining valuable repair time for maintenance personnel, and ensuring the normal transportation of oil.

[0010] Furthermore, a water filling channel is provided on the lower inner wall of the water storage inner ring, and a plurality of oil-soluble particles are clamped at the inner end of the water filling channel.

[0011] Furthermore, two contact blocks are symmetrically fixedly connected to the front inner wall of the guide inner ring, and two alarm light sources are fixedly connected to the lower side of the outer end of the arc-shaped clamping ring. A conductive channel is provided between the contact block and the alarm light source on the same side. When the repair agent in the repair agent filling inner ring is used up, the oil agent at the oil leakage point will flow along the secondary leakage point to the guide inner ring. When the oil-soluble particles in the water filling channel come into contact with the oil, they are also dissolved. The water in the water storage inner ring flows into the guide inner ring through the water filling channel and does not pass through the two contact blocks. At this time, the water will open the conductive channel between the corresponding contact block and the alarm light source, causing the alarm light source to light up, reminding the inspection personnel that a leakage fault has occurred here and needs to be manually repaired in time.

[0012] Furthermore, the plurality of oil-soluble particles and the oil-soluble inner balls are all made of oil-soluble materials and are soluble in oil.

[0013] Furthermore, the conductive medium in the conductive channel is water, the water storage inner ring is filled with water, and water is immiscible with the oil.

[0014] Furthermore, the capacities of the water storage inner ring and the diversion inner ring are substantially equal, and the water storage inner ring and the diversion inner ring are connected to each other through a water filling channel.

[0015] Furthermore, two sealing inner rings are fixedly connected to the inner sides of the ends of the two arc-shaped clamping rings that are close to each other, and the two sealing inner rings are respectively located at the ends of the two arc-shaped clamping rings that are away from each other. The two sealing inner rings are respectively wrapped around the outer ends of the first pipe and the second pipe. By arranging a sealing inner ring with a sealing effect at the part where the arc-shaped clamping ring is connected to the outside to wrap the outer ends of the first pipe and the second pipe, it is beneficial to increase the sealing of the internal flow of the first pipe and the second pipe and effectively prevent its overflow.

[0016] Furthermore, two liquid-absorbing sponge rings are fixedly connected to the inner sides of the two arc-shaped retaining rings. The two liquid-absorbing sponge rings are respectively located on the front and rear sides of the connection between the first and second pipes, and the two liquid-absorbing sponge rings are respectively wrapped around the outer ends of the first and second pipes. Leaked oil can also be blocked within the two arc-shaped retaining rings, and the liquid is absorbed by the liquid-absorbing sponge rings within the two arc-shaped retaining rings, slowing the overflow of the oil and preventing the adverse effects of oil dripping on other pipe components.

[0017] Furthermore, two threaded holes are symmetrically provided at the front and rear ends of the side ear piece, and the inner ends of the threaded holes are threadedly connected with locking bolts.

[0018] Furthermore, the liquid-absorbing sponge ring is made of PVA water-absorbing sponge material.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In the process of the first pipeline and the second pipeline being clamped together to form a long pipeline, the present invention first connects the two arc-shaped clamping rings through the side ear pieces on their side threads to form a seal to seal and protect the connection between the first pipeline and the second pipeline. When an oil leak occurs between the first pipeline and the second pipeline, the oil at the leak flows to the oil-soluble inner ball on the inner side of the repair agent filling inner ring. After the oil-soluble inner ball is dissolved, the repair agent in the repair agent filling inner ring flows out to seal the oil leak, thereby avoiding the risk of a large amount of oil leakage not being repaired in time and causing losses to the enterprise. Compared with the existing sensor detection method, this method can not only perform preliminary sealing on the connection between the first pipeline and the second pipeline and strengthen the connection force, but also perform temporary self-repair on the oil leak points that may occur therein, effectively delaying the amount of oil leaked from the pipeline, gaining valuable repair time for maintenance personnel, and ensuring the normal transportation of oil.

[0022] (2) When the repair agent in the inner ring is used up, the oil agent at the oil leak point will flow along the secondary leak point to the inner ring of the diversion. When the oil-soluble particles in the water filling channel come into contact with the oil, they will also be dissolved. The water in the water storage inner ring flows through the water filling channel to the inner ring of the diversion and does not pass through the two contact blocks. At this time, the water will open the conductive channel between the corresponding contact block and the alarm light source, causing the alarm light source to light up, reminding the inspection personnel that a leak has occurred here and that it needs to be repaired manually in time.

[0023] (3) The leaked oil can also be sealed in the two arc-shaped clamping rings, and the liquid is adsorbed by the liquid-absorbing sponge rings in the two arc-shaped clamping rings, which slows down the overflow speed of the oil and avoids the adverse effects of random dripping of the oil on other pipeline components.

[0024] (4) By providing a sealing inner ring with a sealing effect at the portion where the arc-shaped clamping ring is connected to the outside to wrap the outer ends of the first pipe and the second pipe, it is beneficial to increase the sealing of the internal flow of the first pipe and the second pipe and effectively prevent its overflow.

[0025] (5) The leaked oil can also be sealed in the two arc-shaped clamping rings, and the liquid agent is adsorbed by the liquid-absorbing sponge rings in the two arc-shaped clamping rings, which slows down the overflow speed of the oil and avoids the adverse effects of random dripping of the oil on other pipeline components.

[0041] Example 1:

[0042] See also Figure 1-Figure 7 A connecting piece for a petroleum pipeline with a self-repairing function includes a first pipe 1 and a second pipe 2. The first pipe 1 and the second pipe 2 are engaged with each other. Two arc-shaped clamping rings 3 are provided at one end of the first pipe 1 and the second pipe 2 close to each other. The left and right ends of the two arc-shaped clamping rings 3 are fixedly connected with side ear pieces 4. Two threaded holes are symmetrically provided at the front and rear ends of the side ear pieces 4. The inner ends of the threaded holes are threadedly connected with locking bolts. The two corresponding side ear pieces 4 are bolted together. The two arc-shaped clamping rings 3 wrap the connection between the first pipe 1 and the second pipe 2. The two arc-shaped clamping rings 3 The inner end of the self-test inner ring 8 is provided, and the self-test inner ring 8 is located at the outer end of the connection between the first pipe 1 and the second pipe 2. The inner end of the self-test inner ring 8 is fixedly connected to the water storage inner ring 9, and the inner end of the water storage inner ring 9 is fixedly connected to the diversion inner ring 10. The inner end of the diversion inner ring 10 is fixedly connected to the repair agent filled inner ring 11. The inner end of the repair agent filled inner ring 11 is filled with repair agent. The inner end of the guide inner ring 10 is fixedly connected to a plurality of oil-soluble inner balls 12. The oil-soluble inner balls 12 are in contact with the connection between the first pipe 1 and the second pipe 2, and the repair agent cooperates with the connection between the first pipe 1 and the second pipe 2.

[0043] When the first pipe 1 and the second pipe 2 are connected to each other to form a long pipe, the two arc-shaped clamping rings 3 are firstly connected through the side ear pieces 4 on the side thereof to form a seal to seal and protect the connection between the first pipe 1 and the second pipe 2. This method can ensure that the first pipe 1 and the second pipe 2 The connection strength and sealing between them, and when an oil leak occurs between the first pipe 1 and the second pipe 2, the inner side of the repair agent filling inner ring 11 arranged at the connection between the first pipe 1 and the second pipe 2 and adhered thereto is filled with a repair agent with a sealing function. When the oil at the oil leak flows to the oil-soluble inner ball 12 inside the repair agent filling inner ring 11, the oil-soluble inner ball 12 is dissolved and the repair agent in the repair agent filling inner ring 11 flows out to seal the oil leak point, avoiding the risk of large-scale oil leakage without timely repair causing corporate losses. Compared with the existing sensor detection method, this method can not only preliminarily seal the connection between the first pipe 1 and the second pipe 2 and strengthen the connection force, but also temporarily self-repair the oil leak points that may occur therebetween, effectively delaying the amount of oil leaking from the pipeline, gaining precious repair time for maintenance personnel, and ensuring the normal transportation of oil.

[0044] See also Figures 4-10 A water filling channel 14 is provided on the lower inner wall of the water storage inner ring 9, and a plurality of oil-soluble particles 13 are engaged with the inner end of the water filling channel 14. Two contact blocks 15 are symmetrically fixedly connected to the front inner wall of the diversion inner ring 10, and two alarm light sources 7 are fixedly connected to the lower side of the outer end of the arc-shaped clamping ring 3. A conductive channel is provided between the contact block 15 and the alarm light source 7 on the same side. The plurality of oil-soluble particles 13 and the oil-soluble inner ball 12 are all made of oil-soluble material and are soluble in oil. The conductive medium in the conductive channel is water. The water storage inner ring 9 is filled with water, and water and oil are immiscible. The capacity of the water storage inner ring 9 and the diversion inner ring 10 is basically equal, and the water storage inner ring 9 and the diversion inner ring 10 are connected to each other through the water filling channel 14.

[0045] When the repair agent in the repair agent filling inner ring 11 is used up and the repair efficiency is low and the oil leakage point can no longer be repaired, the oil at the oil leakage point will flow along the secondary leakage point to the guide inner ring 10, and flow along the arc-shaped inner wall of the guide inner ring 10 to the water filling channel 14 at the lower end. When the oil-soluble particles 13 in the water filling channel 14 come into contact with the oil, they are also dissolved, causing the water filling channel 14 to be opened. The water in the water storage inner ring 9 flows into the guide inner ring 10 through the water filling channel 14 and does not cover the two contact blocks 15. Since water and oil are immiscible, the water at this time opens the conductive channel between the corresponding contact block 15 and the alarm light source 7, and uses the conductivity of water to make the alarm light source 7 light up, reminding the inspection personnel that a leakage fault has occurred here and needs to be manually repaired in time.

[0046] See also Figure 1Two sealing inner rings 5 are fixedly connected to the inner sides of the ends of the two arc-shaped clamping rings 3 that are close to each other, and the two sealing inner rings 5 are respectively located at the ends of the two arc-shaped clamping rings 3 that are away from each other, and the two sealing inner rings 5 are respectively wrapped around the outer ends of the first pipe 1 and the second pipe 2.

[0047] By arranging a sealing inner ring 5 with a sealing effect at the portion where the arc-shaped clamping ring 3 is connected to the outside to wrap the outer ends of the first pipe 1 and the second pipe 2, it is beneficial to increase the sealing of the internal flow of the first pipe 1 and the second pipe 2 and effectively prevent its overflow.

[0048] See also Figure 3 Two liquid-absorbing sponge rings 16 are fixedly connected to the inner sides of the two arc-shaped clamping rings 3, and the two liquid-absorbing sponge rings 16 are respectively located on the front and back sides of the connection between the first pipe 1 and the second pipe 2. The two liquid-absorbing sponge rings 16 are respectively wrapped around the outer ends of the first pipe 1 and the second pipe 2. The material of the liquid-absorbing sponge ring 16 is PVA water-absorbing sponge material.

[0049] At this time, the leaked oil can also be sealed in the two arc-shaped clamping rings 3, and the liquid is absorbed by the liquid-absorbing sponge rings 16 in the two arc-shaped clamping rings 3, which slows down the overflow speed of the oil and avoids the adverse effects of random dripping of the oil on other pipeline components.

[0050] See also Figures 1-10When the first pipe 1 and the second pipe 2 are clamped together to form a long pipe, the two arc-shaped clamping rings 3 are first threadedly connected through the side ear pieces 4 on the side thereof to form a seal to seal and protect the connection between the first pipe 1 and the second pipe 2. When an oil leak occurs between the first pipe 1 and the second pipe 2, the oil at the leak flows to the oil-soluble inner ball 12 inside the repair agent-filled inner ring 11. After the oil-soluble inner ball 12 is dissolved, the repair agent in the repair agent-filled inner ring 11 flows out to partially block the oil leak, thereby avoiding the risk of large-scale oil leakage and failure to repair in time to cause corporate losses. Compared with the existing sensor detection method, this method can not only preliminarily seal the connection between the first pipe 1 and the second pipe 2 and strengthen the connection force, but also can repair the oil leak points that may occur in the middle, which is beneficial to the operation of the pipeline 1 and the second pipe 2. In order to ensure the normal transportation of oil, when the repair agent in the inner ring 11 is used up, the oil at the oil leakage point will flow along the secondary leakage point to the inner guide ring 10, and the oil-soluble particles 13 in the water filling channel 14 will also be dissolved when they come into contact with the oil. The water in the water storage inner ring 9 flows through the water filling channel 14 to the inner guide ring 10 and does not pass through the two contact blocks 15. At this time, the water will open the conductive channel between the corresponding contact block 15 and the alarm light source 7, making the alarm light source 7 light up, prompting the inspection personnel that a leakage fault has occurred here and needs to be repaired manually in time. At this time, the leaked oil can also be sealed in the two arc-shaped clamping rings 3, and the liquid is adsorbed by the liquid-absorbing sponge rings 16 in the two arc-shaped clamping rings 3, which slows down the overflow speed of the oil and avoids the adverse effects of random dripping of oil on other pipeline components.
