Description

Technical Field

[0001] This utility model relates to the field of hose fitting technology, specifically hose fittings for marine oil and gas transportation. Background Technology

[0002] Oil and gas pipelines are mainly used to transport oil and natural gas. Many oil and gas pipelines are laid on the seabed. These marine pipelines often bear high water pressure, so the stability of the pipeline joints is crucial for the normal transportation of oil and gas.

[0003] Currently, marine pipeline joints are generally connected using welding and bolting. When welding, the welding process alters the metallographic structure and mechanical properties of the joint material. Disturbances from seabed currents, the movement of marine life, and seasonal climate changes can all cause vibrations, which may affect the stability of the weld. When vibration causes weld cracking, it can lead to serious accidents. Furthermore, welding makes replacement inconvenient. Bolting requires anti-loosening designs. Current anti-loosening measures generally involve mechanical anti-loosening and the use of locking agents. Mechanical anti-loosening uses double threads and increased preload, but it cannot completely prevent loosening. Over time, bolts at the connection may still loosen under vibration. When using locking agents, the complex deep-sea environment means that seawater and sand can seep in and affect the locking effect. Under high pressure, loose pipeline connections can lead to decreased sealing performance and, in severe cases, pipeline leaks, causing significant losses. To address these issues, this paper proposes technological innovations based on existing marine oil and gas pipeline hose joints. Utility Model Content

A spring 43 is fixedly installed in the second mounting hole, and a round-headed pin 44 is fixedly installed on the outside of the spring 43. The round head of the round-headed pin 44 is inserted into the positioning hole. The connecting ring 2 houses a second connector 27 and a first connector 22. A set of oil and gas conveying hoses 1 are connected to the opposite sides of the second connector 27 and the first connector 22. The connecting ring 2 is fixedly installed on the outer ring of the second connector 27. The connecting ring 2 and the second connector 27 are integrally formed. The connector 22 is located to the right of the second connector 27. Through holes are evenly distributed on the left sides of both the second connector 27 and the first connector 22. A bolt 25 is rotatably placed within each through hole, and a nut 26 is screwed onto the outside of the bolt 25. The nut 26 is located to the right of the first connector 22. After flipping the flap 24 outwards, the first connector 22 can be inserted into the connecting ring 2. The flap 24, located inside the concave seat 23 on the left side of the connecting ring 2, fits against the left side of the second connector 27. The flap 24, located inside the concave seat 23 on the left side of the connecting ring 2, is located on the outside of... The embedded magnet 4 is magnetically attracted to the second connector 27. The screw head of the bolt 25 is engaged in the slot of the flap 24 located inside the concave seat 23 on the left side of the connecting ring 2. The flap 24 located inside the concave seat 23 on the right side of the connecting ring 2 is in contact with the right side of the first connector 22. The magnet 4 embedded on the outside of the flap 24 located inside the concave seat 23 on the right side of the connecting ring 2 is magnetically attracted to the first connector 22. The nut 26 is engaged in the slot of the flap 24 located inside the concave seat 23 on the right side of the connecting ring 2. The magnet 4 is a neodymium iron boron magnet.

[0022] A sealing gasket 3 is placed between the second connector 27 and the first connector 22. A sealing ring 31 is fixedly provided on the outer wall of the sealing gasket 3. A first sealing ring 32 is uniformly fixedly provided on the outer wall of the sealing ring 31. A second sealing ring 33 is uniformly fixedly provided on the inner wall of the sealing ring 31. The sealing gasket 3, the sealing ring 31, the first sealing ring 32 and the second sealing ring 33 are integrally molded. The sealing ring 31 is sleeved on the outer wall of the first connector 22. The outer wall of the sealing ring 31 fits against the inner wall of the connecting ring 2. A first annular groove is uniformly provided on the inner wall of the connecting ring 2. A second annular groove is uniformly provided on the outer wall of the first connector 22. The first sealing ring 32 is placed in the first annular groove and the second sealing ring 33 is placed in the second annular groove.

[0023] Working principle: The sealing gasket 3 and sealing ring 31 are placed inside the connecting ring 2. At this time, the left side of the sealing gasket 3 is in contact with the right side of the second connector 27, and the outer side wall of the sealing ring 31 is in contact with the inner side wall of the connecting ring 2. Then, the flip plate 24 is flipped outward, and the first connector 22 can be inserted into the sealing ring 31. At this time, the bolt 25 is used to thread through the through holes of the second connector 27 and the first connector 22 and screwed into the nut 26. When the nut 26 is tightened with the specified torque, the first connector 22 will press the sealing gasket 3 to the left. At the same time, the first sealing ring 32 and the second sealing ring 33 will be located in the first annular groove of the connecting ring 2 and the second annular groove of the first connector 22, respectively. The sealing gasket 3 seals the second connector 27 and the first connector 22, and the sealing ring 31, the first sealing ring 32 and the second sealing ring 33 seal the first connector 22 and the connecting ring 2. Through multiple seals, the entire connector can be stably sealed in the high-pressure environment at sea.

[0024] When nut 26 is tightened and the head of bolt 25 and nut 26 are aligned with the slots on the flaps 24 on the left and right sides of connecting ring 2, flaps 24 can be loosened. At this time, the torque of torsion spring 42 drives flaps 24 to rotate inward around pivot 41. At this time, the head of bolt 25 and nut 26 are respectively engaged in the slots on the flaps 24 on the left and right sides of connecting ring 2, thereby locking bolt 25 and nut 26. This ensures that bolt 25 and nut 26 will not loosen under the disturbance of seabed currents, the movement of marine life, and vibrations caused by seasonal climate changes. Furthermore, the magnetic attraction of magnet 4 to second connector 27 and first connector 22, and the spring 43 driving round-headed pin 44 to insert into the positioning hole of flap 24, make flap 24 stably fixed on the outside of second connector 27 and first connector 22, thereby ensuring the reliability of flap 24 locking bolt 25 and nut 26.
