Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to a novel pipeline connector for pipeline connection. Background Art

[0002] During pipeline laying or maintenance, it is usually necessary to connect the pipelines. The connection is usually made through flanges. For pipelines that cannot have flanges at the connection ends, flanges are generally welded. For pipelines that do not have the conditions for welding flanges, flanges are added through pipeline connectors or directly connected to pipeline components such as tees, valves, and elbows.

[0003] The sealing and tightness of the connector have a decisive influence on whether the connected pipe will leak water or air.

[0004] In existing pipe joints, rubber gaskets are installed at the flange connection to increase waterproofness. This structure is an elastic support. After the rubber gasket ages, the rubber gasket at the flange connection will have insufficient supporting force, resulting in water leakage. At the same time, due to the aging of the gasket, the supporting force is insufficient, which will also affect the stability of the pipe connection, causing a gap between the two sets of connecting flanges, thereby causing the entire pipe to shake.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0030] Embodiment: Figure 1-Figure 9 As shown, a new type of pipeline connector for pipeline connection includes a first connector 6 and a second connector 7. The first connector 6 and the second connector 7 have the same structure and are both closed. The first connector 6 and the second connector 7 respectively include a sleeve 4, and a connecting flange 3 is installed on the sleeve 4. The first connector 6 and the second connector 7 are sequentially provided with mutually matching pipeline reinforcement sealing mechanisms. The first connector 6 and the second connector 7 are both provided with a driving mechanism for driving the pipeline reinforcement sealing mechanism to close. The driving mechanism structures on the first connector 6 and the second connector 7 are completely the same. The outermost ends of the first connector 6 and the second connector 7 are both provided with pipeline locking sealing mechanisms.

[0031] When connecting the pipes, the outer wall of the pipe head is polished smooth first. At this time, the pipe locking and sealing mechanism is installed first, and the first connector 6 and the second connector 7 are sequentially mounted on the two groups of pipe heads that need to be installed. At this time, the positions of the first connector 6 and the second connector 7 are locked by the pipe locking and sealing mechanism. When the first connector 6 and the second connector 7 are fixedly connected through the connecting flange 3, the driving mechanisms on the first connector 6 and the second connector 7 are driven, so that the pipe reinforcement sealing mechanisms on the first connector 6 and the second connector 7 cooperate with each other to close.

[0032] The driving mechanism is provided with a limit mechanism for stopping the rotation of the driving mechanism, and the pipeline reinforcement sealing mechanism is provided with a secondary sealing mechanism, and the pipeline reinforcement sealing mechanism and the secondary sealing mechanism form a group of labyrinth sealing structures;

[0033] In the labyrinth seal structure, when the leaked liquid flows in the labyrinth, the friction caused by the viscosity of the liquid slows down the flow rate and reduces the flow rate (leakage). When the drive mechanism is driven, the drive limit mechanism can position and lock the drive mechanism.

[0034] The pipeline reinforcement sealing mechanism includes a first movable cavity 16, a first movable cavity 16 is provided on the sleeve 4 of the first connector 6, a reinforcement sleeve 21 is slidably installed in the first movable cavity 16, a plug 23 is fixedly installed on the reinforcement sleeve 21 in the second connector 7, a groove body for placing a sealing ring is provided on the outer side of the reinforcement sleeve 21 located on both sides of the plug 23, and a second sealing groove 26 for placing a sealing ring is provided on the top of the plug 23 at the same time, a pipe groove 31 matching the plug 23 is provided on the reinforcement sleeve 21 in the first connector 6, a fifth sealing groove 34 matching the second sealing groove 26 is installed on the inner top of the pipe groove 31, and a third sealing groove 32 matching the groove body is provided on the bottom of the reinforcement sleeve 21 located on both sides of the pipe groove 31;

[0035] The driving mechanism drives the reinforcement sleeve 21 on the first connector 6 and the second connector 7 to move longitudinally. At this time, the reinforcement sleeve 21 moves longitudinally to trigger the secondary sealing mechanism, and the movement of the reinforcement sleeve 21 can be completed. When the reinforcement sleeve 21 completes the movement, the insert tube 23 is inserted into the tube groove 31, and the insert tube 23 squeezes the sealing ring in the tube groove 31 for reinforcement.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the pipeline locking and sealing mechanism includes a slot 15, and the inner wall of one end of the sleeve 4 away from the closed part is arranged in an inclined structure. A slot 15 is provided on the outer side of one end of the sleeve 4 away from the closed part. A clamping block 14 is clamped in the slot 15. The clamping block 14 is arranged in a circular ring structure. The clamping block 14 is rotatably connected with the sleeve 4 through the slot 15. The outer wall of the clamping block 14 is fixedly installed with a connecting sleeve 2. An internal thread is provided on the inner wall of the connecting sleeve 2. A sealing rubber ring 5 is placed in the connecting sleeve 2. The sealing rubber ring 5 is arranged in an open circular ring structure. A locking hoop 1 is threadedly installed on the connecting sleeve 2. An external connecting thread 11 for threaded connection of the connecting sleeve 2 is provided on the outer wall of the locking hoop 1. The locking hoop 1 is fitted with the sealing rubber ring 5. A side wall where the locking hoop 1 fits with the sealing rubber ring 5 is arranged in an arc shape. Both side walls where the sealing rubber ring 5 contacts the locking hoop 1 and the sleeve 4 are arranged in an arc shape.

[0037] The pipeline is polished first. After polishing, the locking hoop 1 is locked with the pipeline, and the sealing rubber ring 5 is fitted with the locking hoop 1. The first connector 6 and the second connector 7 are inserted into the pipeline head. The connecting sleeve 2 is rotated to thread the connecting sleeve 2 with the locking hoop 1. During the threaded connection, the locking hoop 1 and the connecting sleeve 2 squeeze the sealing rubber ring 5, so that the sealing rubber ring 5 locks the pipeline, so that the locking hoop 1, the connecting sleeve 2 and the pipeline are sealed.

[0038] like Figure 5 and Figure 6 As shown, the driving mechanism includes a locking collar 8, a positioning collar 17, an adjusting tooth 18, a movable tooth 19, a first gear 20 and a second gear 22. The inner wall of the first movable cavity 16 is rotatably mounted with a plurality of groups of second gears 22 arranged in an annular array. The reinforcement sleeve 21 is located in a section inside the first movable cavity 16 and is provided with a mounting groove. The number of the mounting grooves is a plurality of groups and is arranged in an annular array. The inner wall of the mounting groove is fixedly mounted with movable teeth 19, which are meshed with the second gear 22. The outer wall of the sleeve 4 is rotatable. A first gear 20 is installed, and the number of the first gears 20 is several groups and corresponds to the second gear 22. The rotating shaft of the first gear 20 transversely penetrates the sleeve 4 and is fixedly connected to the rotating shaft of the second gear 22. A positioning ring 17 is fixedly installed on the outer wall of the sleeve 4. A locking ring 8 is sleeved on the positioning ring 17. An adjusting tooth 18 is installed on the inner wall of the locking ring 8. The adjusting tooth 18 is an inclined structure. The adjusting tooth 18 is meshed with the first gear 20, and the adjusting tooth 18 is corresponding to the limit tooth.

[0039] The locking ring 8 is moved to rotate. Since the locking ring 8 is provided with an adjusting tooth 18 meshing with the first gear 20, the first gear 20 rotates accordingly. At this time, the first gear 20 drives the second gear 22 to rotate. At this time, since the second gear 22 is meshing with the movable tooth 19, the movable tooth 19 drives the reinforcement sleeve 21 to move longitudinally, thereby completing the extension and retraction of the reinforcement sleeve 21.

[0040] like Figure 7-Figure 8 As shown, the secondary sealing mechanism includes a second active cavity 25, a second active cavity 25 is provided on the sleeve 4 of the second connector 7, the second active cavity 25 is connected to the first active cavity 16, a sealing block 27 is slidably installed in the first active cavity 16 and the second active cavity 25, the sealing block 27 is fixedly connected to the reinforcement sleeve 21, a fourth sealing groove 33 is provided on the sealing block 27, a rubber sealing ring is provided in the fourth sealing groove 33, and a matching first sealing groove 24 is provided on the corresponding side wall of the fourth sealing groove 33.

[0041] When the reinforcement sleeve 21 is extended, the sealing block 27 moves longitudinally in the second movable cavity 25, so that the sealing block 27 fits against the inner wall of the second movable cavity 25, and the fourth sealing groove 33 on the sealing block 27 is closed with the corresponding first sealing groove 24, thereby further sealing and reinforcing.

[0042] like Fig. 9As shown, the limiting mechanism includes a toggle plate 29, a threaded rod 28, a guide rod 30 and a positioning tooth 35. The locking ring 8 is located on a side wall where the adjusting tooth 18 is installed and the threaded rod 28 is slidably installed. The threaded rod 28 is located inside the locking ring 8 and one end is rotatably installed with the positioning tooth 35. The bottom of the positioning tooth 35 is located on both sides of the threaded rod 28 and the guide rod 30 is fixedly installed. The guide rod 30 is slidably connected to the locking ring 8. The outer side wall of the locking ring 8 is rotatably installed with a toggle plate 29. The toggle plate 29 is sleeved on the threaded rod 28 and is threadedly connected with the threaded rod 28. The positioning ring 17 is located on a side wall of the first gear 20 and the limiting tooth is fixedly installed. The limiting tooth does not contact the first gear 20, and the positioning tooth 35 is meshed with the limiting tooth.

[0043] After the locking collar 8 has been rotated, the user rotates the dial 29. Since the threaded rod 28 is threadedly connected to the dial 29 and the threaded rod 28 is limited by the guide rod 30, the threaded rod 28 moves longitudinally, thereby causing the positioning teeth 35 to move longitudinally and engage with the limiting teeth to complete the fixed limit of the locking collar 8.

[0044] like Figure 3 As shown, the locking hoop 1 includes a first half hoop 12, a second half hoop 13, a hidden mounting hole 10 and a locking bolt 9. The inner walls of the first half hoop 12 and the second half hoop 13 are both provided with anti-slip rubber pads. The size and structure of the first half hoop 12 and the second half hoop 13 are the same and are hingedly connected. The outer walls of the closed part of the first half hoop 12 and the second half hoop 13 are both provided with hidden mounting holes 10. The locking bolt 9 is installed with the inner thread of the hidden mounting hole 10. The first half hoop 12 and the second half hoop 13 are fixed and closed by the locking bolt 9.

[0045] like Figure 1-Figure 9 As shown, the first connector 6 and the second connector 7 are both installed at the connecting ends of the pipes, and the connecting ends of the pipes in the first connector 6 and the second connector 7 are located at a distance of 2-3 cm from the corresponding connecting flanges 3 .

[0046] Working principle: The pipeline is polished first. After polishing, the locking hoop 1 is locked with the pipeline, and the sealing rubber ring 5 is fitted with the locking hoop 1. The first connector 6 and the second connector 7 are inserted into the pipeline head. The connecting sleeve 2 is rotated to make the connecting sleeve 2 and the locking hoop 1 threadedly connected. At the same time, the locking hoop 1 and the connecting sleeve 2 squeeze the sealing rubber ring 5, so that the sealing rubber ring 5 locks the pipeline, so that the locking hoop 1, the connecting sleeve 2 and the pipeline are sealed;

[0047] The locking collar 8 is turned to rotate. Since the locking collar 8 is provided with an adjusting tooth 18 meshing with the first gear 20, the first gear 20 rotates accordingly. At this time, the first gear 20 drives the second gear 22 to rotate. Since the second gear 22 is meshing with the movable tooth 19, the movable tooth 19 drives the reinforcement sleeve 21 to move longitudinally. At this time, the reinforcement sleeve 21 moves longitudinally until the secondary sealing mechanism is triggered, and the movement of the reinforcement sleeve 21 can be completed. When the reinforcement sleeve 21 has completed the movement, the insert tube 23 is inserted into the tube groove 31. At the same time, the insert tube 23 squeezes the sealing ring in the tube groove 31 for reinforcement. The fourth sealing groove 33 on the sealing block 27 is closed with the corresponding first sealing groove 24 to further perform sealing reinforcement.

[0048] When the reinforcement sleeve 21 is extended, the sealing block 27 is located in the second active chamber 25 and moves longitudinally, so that the sealing block 27 fits against the inner wall of the second active chamber 25, thereby causing the sealing block 27 to squeeze the sealing ring on the second active chamber 25, completing the sealing of the reinforcement sleeve 21 and the first active chamber 16. After the locking ring 8 is rotated, the user rotates the dial 29. Since the threaded rod 28 is threadedly connected to the dial 29 and the threaded rod 28 is limited by the guide rod 30, the threaded rod 28 moves longitudinally, thereby causing the positioning teeth 35 to move longitudinally and engage with the limiting teeth to complete the fixed limit of the locking ring 8.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
