Description

Technical Field

[0001] The invention relates to the technical field of pipelines, and in particular to a seal for a quick-detachable oil and gas pipeline. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.

[0003] However, most existing seals lack effective airtightness monitoring methods and are unable to accurately and timely grasp the sealing status of the pipeline. As a result, during the operation of the pipeline, even if there is a slight leak in the seal, it is difficult to detect it in the first time. As time goes by, these slight leaks may gradually expand and eventually cause serious oil and gas leakage accidents, which will not only cause a waste of resources, but also pose a huge threat to the environment and personnel safety.

[0004] In view of this, the existing problems are studied and improved, and a quick-disassembly seal for oil and gas pipelines is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a quick-detachable oil and gas pipeline seal is proposed. The present invention realizes the initial locking of the seal by manually operating the docking rod and the locking rod, and cooperates with the push plate and the push head to fix the locking rod, thereby enhancing the stability of the connection and simplifying the installation and maintenance. The leaking gas is used to move the movable plug. Combined with the scale line and the sensor, the leakage can be judged in time and the alarm can be given to enhance the safety. The movable plug is pushed by the gas, which drives the push plate and the push head to release the plug lock, thereby realizing the quick disassembly of the seal, improving the maintenance efficiency and reducing the cost.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a seal of a quick-detachable oil and gas pipeline, comprising a seal one and a seal two, wherein two sides of the seal one are welded with symmetrically arranged mounting seats, a docking rod is arranged inside the mounting seat through a rotating shaft, and docking grooves that are engaged with the docking rod are opened on two sides of the seal two, a locking rod is slidably installed inside the docking groove, a mounting groove is opened inside the locking rod, a plug rod is slid inside the mounting groove, and a slot that is engaged with the plug rod is opened inside the docking rod, one side of the seal one is connected to a connecting pipe, one end of the connecting pipe is connected to a sleeve, a movable plug is slid inside the sleeve, one side of the movable plug is fixedly connected to a guide rod, and one end of the guide rod that passes through the sleeve is fixedly connected to a push plate, two sides of the push plate are fixedly connected to moving rods, and one end of the moving rod is fixedly connected to a push head.

[0007] Preferably: the inner walls of the sealing member 1 and the sealing member 2 are both fixedly connected with a backing plate, and a sealing rubber ring 1 is fixedly installed on one side of the backing plate.

[0008] Preferably, one end of the docking rod is provided with a plug hole for the locking rod to pass through, and the inner diameter dimension tolerance of the plug hole matches the outer diameter dimension tolerance of the locking rod.

[0009] Preferably, a spring A is sleeved on the outer wall of the locking rod, the bottom of the spring A is fixedly connected to the top of the second sealing member, and the top of the spring A is fixedly connected to the top of the locking rod.

[0010] Preferably, a limiting plate is provided inside the installation groove for sliding movement, the limiting plate is fixedly sleeved on the outer wall of the insertion rod, and a plurality of groups of springs B are installed between the inside of the installation groove and the limiting plate.

[0011] Preferably, the sleeve is made of a transparent material, and the outer wall of the sleeve is provided with scale lines.

[0012] Preferably, one end of the insertion rod is arranged in an inclined shape, and both side walls of the top of the pushing head are arranged in an inclined shape.

[0013] Preferably, a movable groove communicating with each other is provided between the sealing member 1 and the sealing member 2, and the guide rod slides inside the movable groove.

[0014] Preferably: a sensor is installed inside the sleeve, a contact switch is installed on the surface of the sensor, an alarm is installed on the outer wall of the sleeve, and the sensor and the alarm are electrically connected through a wire.

[0015] Preferably: a sealing rubber ring 2 is fixedly installed on one side opposite to the sealing member 1 and the sealing member 2, and the sealing rubber ring 2 is made of rubber material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention manually pulls up the docking rod and rotates the docking rods on both sides of the seal one, so that the docking rod is inserted into the docking groove of the seal two, and the locking rod is loosened at the same time, so that the locking rod is inserted into the insertion hole of the docking rod under the elastic potential energy of the spring A, thereby realizing the initial locking of the seal one and the seal two, without the need for complex tools and professional skills, greatly saving installation time and labor costs. At the same time, the push plate is manually pushed, so that the push plate drives the guide rod to move, and the guide rod drives the moving rods on both sides to move and drive the push head at its top to move, and when the push head touches the insertion rod, the push head pushes the insertion rod to move toward the inside of the slot, thereby realizing the fixing of the locking rod, and the stability of the connection between the seal one and the seal two is effectively enhanced through the multiple locking structures, ensuring the stable operation of the oil and gas pipeline under complex working conditions, greatly simplifying the installation and maintenance process of the oil and gas pipeline seal, and ensuring the normal operation of the oil and gas pipeline.

[0018] 2. The present invention utilizes the gas leaked between seal one and seal two, so that the leaked gas enters the inner cavity of seal one and seal two, so that the pressure of the inner cavity increases continuously, and the gas enters the interior of the sleeve through the connecting pipe, so that the gas pushes the movable plug to move reversely inside the sleeve. The reverse movement of the movable plug can be observed through the scale lines on the outer wall of the sleeve, so as to preliminarily judge whether there is gas leakage at the pipeline connection. When the movable plug moves to a certain position and touches the contact switch on the surface of the sensor, the contact switch will trigger the alarm to sound an alarm. The alarm reminds the operator to take timely measures by flashing or making sounds, so as to avoid oil and gas leakage accidents caused by sealing failure, thereby enhancing the safety of oil and gas pipeline operation.

[0019] 3. The present invention allows leaked gas to enter the interior of the seal and the sleeve through the connecting pipe. The gas pushes the movable plug to move in the sleeve. The movable plug moves in the opposite direction under the action of the gas pressure, so that the guide rod drives the push plate to move, and the push plate drives the moving rods on both sides to move synchronously. The moving rod then drives the push head to move, so that the push head and the insertion rod are separated from each other, thereby releasing the lock on the insertion rod. After the insertion rod is withdrawn from the slot, the locking relationship between the locking rod and the docking rod is released, and the maintenance personnel can quickly rotate the docking rod and pull it out of the docking groove, thereby quickly disassembling the seal one and the seal two, which is convenient for maintenance or replacement, thereby realizing the rapid disassembly of the seal, so that the operator can complete the insertion and removal of the insertion rod through a simple pushing action, further improving the convenience of disassembly and installation, and when the pipeline needs to be repaired or parts need to be replaced, the seal can be easily separated, which is convenient for subsequent operations, improves maintenance efficiency, and reduces maintenance costs.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 10 As shown, the present invention provides a seal for a quick-detachable oil and gas pipeline, comprising a seal 1 and a seal 2, wherein symmetrically arranged mounting seats 5 are welded on both sides of the seal 1, a docking rod 6 is rotated inside the mounting seat 5 through a rotating shaft, docking grooves 8 for engaging with the docking rod 6 are provided on both sides of the seal 2, a locking rod 9 is slidably installed inside the docking groove 8, a mounting groove 11 is provided inside the locking rod 9, an insertion rod 13 is slid inside the mounting groove 11, a slot 14 for engaging with the insertion rod 13 is provided inside the docking rod 6, a connecting pipe 16 is connected to one side of the seal 1, a sleeve 17 is connected to one end of the connecting pipe 16, a movable plug 18 is slid inside the sleeve 17, a guide rod 19 is fixedly connected to one side of the movable plug 18, a push plate 20 is fixedly connected to one end of the guide rod 19 that passes through the sleeve 17, a moving rod 21 is fixedly connected to both sides of the push plate 20, and a push head 22 is fixedly connected to one end of the moving rod 21.

[0034] It should be noted that when it is necessary to install the pipeline, first manually pull up the docking rod 6, then rotate the docking rods 6 on both sides of the seal 1, so that one end of the two sets of docking rods 6 are respectively inserted into the docking grooves 8 on both sides of the seal 2, and at the same time release the locking rod 9, so that the locking rod 9 is inserted into the insertion hole 7 of the docking rod 6 under the elastic potential energy of the spring A10, thereby realizing the preliminary locking of the seal 1 and the seal 2, without the need for complex tools and professional skills, greatly saving installation time and labor costs, and at the same time, manually push the push plate 20, so that the push plate 20 drives the guide rod 19 to move , further, the guide rod 19 drives the moving rods 21 on both sides to move, so that the moving rod 21 drives the push head 22 on the top thereof to move. When the push head 22 touches the insertion rod 13 during the movement, the push head 22 and the insertion rod 13 fit each other, so that the push head 22 pushes the insertion rod 13 to move inside the slot 14, thereby fixing the locking rod 9. The multiple locking structures effectively enhance the stability of the connection between the seal 1 and the seal 2, ensure the stable operation of the oil and gas pipeline under complex working conditions, greatly simplify the installation and maintenance process of the oil and gas pipeline seal, and ensure the normal operation of the oil and gas pipeline;

[0035] In addition, when the pipeline connection is not tight, gas leakage will occur between the seal 1 and the seal 2, so that the leaked gas enters the inner cavity of the seal 1 and the seal 2, so that the pressure of the inner cavity continues to increase, and the gas enters the inside of the sleeve 17 through the connecting pipe 16, so that the gas pushes the movable plug 18 to move reversely inside the sleeve 17. The reverse movement of the movable plug 18 can be observed through the scale line 24 on the outer wall of the sleeve 17, so as to preliminarily judge whether there is gas leakage at the pipeline connection. When the movable plug 18 moves to a certain position and touches the contact switch 26 on the surface of the sensor 25, the contact switch 26 will trigger the alarm 27 to sound an alarm. The alarm 27 reminds the operator to take timely measures by flashing or making sounds, so as to avoid oil and gas leakage accidents caused by sealing failure, thereby enhancing the safety of oil and gas pipeline operation.

[0036] It should be noted that when there is a gas leak, the leaked gas enters the interior of the seal and enters the sleeve 17 through the connecting pipe 16, and the gas pushes the movable plug 18 to move in the sleeve 17. The movable plug 18 moves in the opposite direction under the action of the gas pressure, so that the movable plug 18 drives the guide rod 19 to move in the opposite direction synchronously, and the reverse movement of the guide rod 19 further drives the push plate 20 to move in the opposite direction, so that the moving rods 21 on both sides of the push plate 20 move in the opposite direction synchronously, and the moving rod 21 drives the push head 22 at the top thereof to move in the opposite direction. When the moving rod 21 drives the push head 22 to move in the opposite direction, the push head 22 and the insertion rod 13 are separated from each other, and under the action of the elastic potential energy of the spring B15, the insertion rod 13 is The rod 13 automatically returns to its initial position, thereby releasing the lock on the plug rod 13. After the plug rod 13 is withdrawn from the slot 14, the locking relationship between the locking rod 9 and the docking rod 6 is released, and the maintenance personnel can quickly rotate the docking rod 6 and pull it out from the docking groove 8, thereby quickly disassembling the seal 1 and the seal 2 2, which is convenient for maintenance or replacement, thereby realizing the rapid disassembly of the seal, so that the operator can complete the insertion and removal of the plug rod 13 by a simple pushing action, further improving the convenience of disassembly and installation, and when the pipeline needs to be repaired or parts need to be replaced, the seal can be easily separated, which is convenient for subsequent operations, improves maintenance efficiency, and reduces maintenance costs.

[0037] See also Figures 2 to 3 As shown, the inner walls of the seal 1 and the seal 2 are both fixedly connected with a gasket 3, and a sealing rubber ring 4 is fixedly installed on one side of the gasket 3. The sealing rubber ring 4 utilizes its elastic material properties to further fill the gap when under pressure, effectively preventing oil and gas leakage, thereby significantly improving the overall sealing performance of the seal.

[0038] See also Figure 4As shown, one end of the docking rod 6 is provided with a socket 7 for the locking rod 9 to pass through, and the inner diameter dimension tolerance of the socket 7 matches the outer diameter dimension tolerance of the locking rod 9, which can ensure that the locking rod 9 can be accurately inserted into the socket 7. This precise matching ensures a stable connection between the docking rod 6 and the locking rod 9, avoids loosening or jamming due to size mismatch, and thus improves the reliability and stability of the seal.

[0039] See also Figure 1 As shown, the outer wall of the locking rod 9 is sleeved with a spring A10, the bottom of the spring A10 is fixedly connected to the top of the sealing member 2, and the top of the spring A10 is fixedly connected to the top of the locking rod 9. When the sealing member needs to be removed, the elastic force of the spring A10 can automatically pop the locking rod 9 out of the socket 7, thereby quickly releasing the lock, making it convenient for maintenance personnel to perform disassembly operations.

[0040] See also Figure 6 to Figure 7 As shown, there is a limiting plate 12 sliding inside the installation groove 11, and the limiting plate 12 is fixedly sleeved on the outer wall of the insertion rod 13. A plurality of springs B15 are installed between the inside of the installation groove 11 and the limiting plate 12. The spring B15 can absorb part of the impact force and reduce mechanical wear. At the same time, when disassembly is required, the elastic potential energy of the spring B15 can automatically bounce the insertion rod 13 back to the initial position, so as to facilitate quick unlocking.

[0041] See also Fig. 9 As shown, the sleeve 17 is made of a transparent material, and a scale line 24 is provided on the outer wall of the sleeve 17. The sleeve 17 made of the transparent material enables the operator to intuitively observe the movement of the movable plug 18 inside the sleeve 17, which is helpful for monitoring the operating status of the seal. Especially when detecting gas leakage, the operator can quickly determine whether there is a leak in the seal by observing the position change of the movable plug 18.

[0042] See also Figures 7 and 8 As shown, one end of the insertion rod 13 is arranged to be inclined, and both side walls of the top of the pushing head 22 are arranged to be inclined. The inclined design enables the insertion rod 13 to enter the slot 14 more smoothly when pushed by the pushing head 22, thereby reducing the friction between the insertion rod 13 and the pushing head 22 and reducing the force required for insertion, thereby improving the insertion efficiency of the insertion rod 13 and saving operation time.

[0043] See also Figure 8 As shown, a movable groove 23 which is interconnected is provided between the seal 1 and the seal 2 2, and the guide rod 19 slides inside the movable groove 23. The movable groove 23 provides a clear sliding path for the guide rod 19, ensuring that the guide rod 19 always maintains a stable and accurate movement direction during the movement.

[0044] See also Fig.10 As shown, a sensor 25 is installed inside the sleeve 17, a contact switch 26 is installed on the surface of the sensor 25, and an alarm 27 is installed on the outer wall of the sleeve 17. The sensor 25 and the alarm 27 are electrically connected through a wire. Through the linkage between the sensor 25 and the alarm 27, the leakage of the seal can be detected in time, and the operator can be reminded to take timely measures.

[0045] See also Figure 1 As shown, a sealing rubber ring 28 is fixedly installed on the opposite side of the sealing member 1 and the sealing member 2 2. The sealing rubber ring 28 is made of rubber material. The sealing rubber ring 28 made of rubber material can effectively prevent oil and gas leakage.

[0046] Working principle: When it is necessary to install the pipeline, first manually pull up the docking rod 6, and then rotate the docking rods 6 on both sides of the seal 1, so that one end of the two sets of docking rods 6 are respectively inserted into the docking grooves 8 on both sides of the seal 2, and at the same time, loosen the locking rod 9, so that the locking rod 9 is inserted into the insertion hole 7 of the docking rod 6 under the elastic potential energy of the spring A10, thereby realizing the preliminary locking of the seal 1 and the seal 2, without the need for complex tools and professional skills, greatly saving installation time and labor costs, and at the same time, manually push the push plate 20, so that the push plate 20 drives the guide rod 19 to move, Further, the guide rod 19 drives the moving rods 21 on both sides to move, so that the moving rod 21 drives the push head 22 on the top thereof to move. When the push head 22 touches the insertion rod 13 during the movement, the push head 22 and the insertion rod 13 fit each other, so that the push head 22 pushes the insertion rod 13 to move inside the slot 14, thereby fixing the locking rod 9. The multiple locking structures effectively enhance the stability of the connection between the seal 1 and the seal 2, ensure the stable operation of the oil and gas pipeline under complex working conditions, greatly simplify the installation and maintenance process of the oil and gas pipeline seal, and ensure the normal operation of the oil and gas pipeline;

[0047] In addition, when the pipeline connection is not tight, gas leakage will occur between the seal 1 and the seal 2, so that the leaked gas enters the inner cavity of the seal 1 and the seal 2, so that the pressure of the inner cavity continues to increase, and the gas enters the inside of the sleeve 17 through the connecting pipe 16, so that the gas pushes the movable plug 18 to move reversely inside the sleeve 17. The reverse movement of the movable plug 18 can be observed through the scale line 24 on the outer wall of the sleeve 17, so as to preliminarily judge whether there is gas leakage at the pipeline connection. When the movable plug 18 moves to a certain position and touches the contact switch 26 on the surface of the sensor 25, the contact switch 26 will trigger the alarm 27 to sound an alarm. The alarm 27 reminds the operator to take timely measures by flashing or making sounds, so as to avoid oil and gas leakage accidents caused by sealing failure, thereby enhancing the safety of oil and gas pipeline operation.

[0048] When there is a gas leak, the leaked gas enters the interior of the seal and enters the sleeve 17 through the connecting pipe 16. The gas pushes the movable plug 18 to move in the sleeve 17. The movable plug 18 moves in the opposite direction under the action of the gas pressure, so that the movable plug 18 drives the guide rod 19 to move in the opposite direction synchronously. The reverse movement of the guide rod 19 further drives the push plate 20 to move in the opposite direction, so that the moving rods 21 on both sides of the push plate 20 move in the opposite direction synchronously, and the moving rod 21 drives the push head 22 at its top to move in the opposite direction. When the moving rod 21 drives the push head 22 to move in the opposite direction, the push head 22 and the insertion rod 13 are separated from each other, and under the action of the elastic potential energy of the spring B15, the insertion rod 13 It automatically returns to its initial position, thereby releasing the lock on the plug rod 13. After the plug rod 13 is withdrawn from the slot 14, the locking relationship between the locking rod 9 and the docking rod 6 is released, and the maintenance personnel can quickly rotate the docking rod 6 and pull it out from the docking groove 8, thereby quickly disassembling the seal 1 and the seal 2 2, which is convenient for maintenance or replacement, thereby realizing the rapid disassembly of the seal, so that the operator can complete the insertion and removal of the plug rod 13 by a simple pushing action, further improving the convenience of disassembly and installation, and when the pipeline needs to be repaired or parts need to be replaced, the seal can be easily separated, which is convenient for subsequent operations, improves maintenance efficiency, and reduces maintenance costs.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
