Description

Technical Field

[0001] This utility model relates to the field of petrochemicals, and in particular to a novel petrochemical transportation pipeline. Background Technology

[0002] An existing patent (publication number: CN210318948U) discloses a pipeline for transporting petrochemical products in ports. The pipeline includes a transport pipe with two symmetrical connecting rings fixedly connected to the sidewalls at both ends. The transport pipe comprises an outer layer, a middle layer, and an inner layer. The middle layer is located on the sidewall of the inner layer, and the outer layer is located on the sidewall of the middle layer. Each of the two connecting rings has multiple first connecting holes spaced at equal intervals around its circumference, with at least six first connecting holes. Both ends of the transport pipe are equipped with a sealing mechanism, and the two connecting rings at the connection point of the transport pipe are equipped with a connecting mechanism. However, in this device, "the second connecting hole is equipped with a locking bolt and nut that are threaded together, and the retaining ring is connected to the connecting ring through the locking bolt and nut." The retaining ring is fixedly connected by bolts, requiring multiple bolts to be tightened one by one. This not only results in low operational efficiency but also, if any bolt loosens, it directly affects the sealing of the pipeline connection, easily leading to oil leakage inside the pipe, thus posing a drawback. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a novel petrochemical pipeline that strengthens pipeline connection stability through dual braking and locking, preventing pipeline loosening due to vibration or pressure fluctuations. This enhances the safety, reliability, and sealing of petrochemical pipeline transportation, while also facilitating easy disassembly and assembly without the need for specialized tools, thereby improving the efficiency of petrochemical pipeline installation and maintenance.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel petrochemical conveying pipeline includes a pipe, a sealing ring, a baffle, a rotating sleeve, a fixed sleeve, a locking plate, a lever, and a strip plate. The rotating sleeve is externally connected to the pipe, and the rotating sleeve has an internal sliding groove. The pipe has a receiving groove, which is compatible with the baffle. The sliding groove connects to the baffle, and the baffle connects to the receiving groove. The baffle connects to the outer end of a spring, and the inner end of the spring connects to the pipe. The pipe has an internal sliding hole, and the baffle has an internal insertion rod groove. The internal insertion rod groove and the internal sliding hole are compatible with an insertion rod, which passes through the internal sliding hole. The inner end of the insertion rod connects to the internal insertion rod groove. The fixed sleeve has a partition in the middle, and pipes are connected to both sides of the partition. The pipe has an insert tube, which has a sealing groove compatible with the sealing ring. The sealing ring connects to the sealing groove. The partition has external insertion rod grooves on both sides, which are compatible with the insertion rod. The outer end of the insertion rod connects to the external insertion rod groove.

[0006] The fixed sleeve of this utility model has an externally fitted rotating sleeve. The rotating sleeve has a threaded support sleeve, which is connected to the fixed sleeve by threads. The fixed sleeve has an externally connected strip plate, and there are clamping plates on both sides of the strip plate. There are clamping plate through holes on both sides of the fixed sleeve. The threaded support sleeve has a clamping groove. The clamping groove and the clamping plate through holes are adapted to the clamping plates. The clamping plates pass through the clamping plate through holes and are connected to the clamping groove.

[0007] The fixed sleeve of this utility model has support plates on both sides, and control plates on both sides of the strip plate. The control plates are attached to the inner side of the support plates, and the outer side of the support plates has a boss. The boss has an outer sliding hole, which is adapted to the lever. The lever passes through the outer sliding hole and the control plate in sequence. The boss is divided into a left boss and a right boss. The left boss has a limiting sliding hole, and the lever has a limiting rod groove. The limiting rod groove and the limiting sliding hole are adapted to the limiting rod. The limiting rod passes through the limiting sliding hole, and the inner end of the limiting rod is connected to the limiting rod groove. Beneficial effects

[0008] This utility model's baffle limits the movement range of the rotating sleeve, preventing it from detaching from the pipeline and falling off. Furthermore, when the threaded support sleeve and the fixed sleeve are fixedly connected, the rotating sleeve increases the thrust strength on the outer side of the baffle, ensuring a tight connection between the pipeline and the baffle. It also works with a sealing ring embedded in the sealing groove to increase the sealing performance of the pipeline connection, preventing oil leakage. The insertion rod adds a control point for the baffle, facilitating quick assembly and disassembly of the rotating sleeve. Simultaneously, by embedding the outer end of the insertion rod into the outer insertion rod groove, it increases the positioning support point between the baffle and the pipeline, preventing axial rotation between the pipeline and the fixed sleeve and enhancing the stability of the pipeline installation.

[0009] This utility model's control support rod is positioned by a threaded connection between the control support sleeve and the locking mechanism, allowing the locking plate to move laterally in a linear fashion by rotating a knob. When the locking plate moves inward until the locking block is embedded in the locking groove, an additional support plate provides a positioning fulcrum for the lever, simultaneously braking and locking the lever and the strip. When the locking plate moves outward until the locking block is completely disengaged from the locking groove, the support plate's positioning fulcrum for the lever disappears. At this point, the lever can be turned to drive the strip in a linear fashion. When the strip moves inward until the locking plate is embedded in the locking groove, an additional fixing sleeve provides an axial positioning fulcrum for the threaded support sleeve, preventing secondary... The relative rotation between the components causes the threaded connection to loosen, thus reinforcing the connection stability. When the strip moves outward until the clamping plate and the groove are completely separated, the positioning fulcrum of the fixed sleeve on the threaded support disappears. At this time, the threaded support and the pipeline can be quickly separated from the fixed sleeve by rotating the rotating sleeve without the need for professional tools. This improves the efficiency of disassembly, assembly and maintenance of petrochemical pipelines, while also reinforcing the stability of the pipeline connection through double braking and locking, preventing the pipeline from loosening due to vibration or pressure fluctuations, and improving the safety and reliability of petrochemical pipeline transportation.

[0010] This utility model strengthens the stability of pipeline connections through double braking and locking, preventing pipelines from loosening due to vibration or pressure fluctuations. It improves the safety, reliability, and sealing of petrochemical pipeline transportation, while also facilitating disassembly and assembly without the need for specialized tools, thus improving the efficiency of petrochemical pipeline installation and maintenance.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0021] Example 1:

[0022] A novel petrochemical conveying pipeline includes a pipe 01, a sealing ring 04, a baffle 05, a rotating sleeve 12, a fixing sleeve 14, a locking plate 25, a lever 28, and a strip 34. The rotating sleeve 12 is externally connected to the pipe 01. The rotating sleeve 12 has a sliding groove 35 inside. The pipe 01 has a receiving groove 06. The receiving groove 06 and the sliding groove 35 are adapted to the baffle 05. The sliding groove 35 is connected to the baffle 05, the baffle 05 is connected to the receiving groove 06, and the baffle 05 is connected to a spring 06. 7. The outer end of the spring 07 is connected to the inner end of the pipe 01. The pipe 01 has an inner sliding hole 09. The baffle 05 has an inner insertion rod groove 10. The inner insertion rod groove 10 and the inner sliding hole 09 are adapted to the insertion rod 08. The insertion rod 08 passes through the inner sliding hole 09. The inner end of the insertion rod 08 is connected to the inner insertion rod groove 10. The middle part of the fixed sleeve 14 has a partition 15. The two sides of the partition 15 are connected to the pipe 01. The pipe 01 has an insertion tube 02. The insertion tube 02 has a sealing groove 03. The sealing groove 03 is connected to the inner insertion rod groove 10. The sealing ring 04 is compatible with the sealing groove 03. The partition 15 has external insertion rod grooves 11 on both sides, which are compatible with the insertion rod 08. The outer end of the insertion rod 08 is connected to the external insertion rod groove 11. The baffle 05 limits the movement range of the rotating sleeve 12 to prevent it from detaching from the pipe 01 and falling off. When the threaded support sleeve 13 is fixedly connected to the fixed sleeve 14, the rotating sleeve 12 will increase the thrust strength on the outside of the baffle 05, ensuring the tightness of the connection between the pipe 01 and the partition 15. It also works with the sealing ring 04 to embed in the sealing groove 03, increasing the sealing performance of the pipe 01 connection and preventing oil leakage. The insertion rod 08 adds a control fulcrum for the baffle 05, facilitating the quick installation and removal of the rotating sleeve 12. At the same time, the insertion rod 08 embeds in the external insertion rod groove 11, increasing the positioning fulcrum between the partition 15 and the pipe 01, preventing axial rotation between the pipe 01 and the fixed sleeve 14, and enhancing the stability of the pipe 01 installation.

[0023] Example 2:

[0024] The fixed sleeve 14 of this utility model is externally fitted with the rotating sleeve 12. The rotating sleeve 12 has a threaded support sleeve 13, which is threadedly connected to the fixed sleeve 14. The fixed sleeve 14 is externally connected to a strip plate 34. The strip plate 34 has a retaining plate 30 on both sides. The fixed sleeve 14 has retaining plate through holes 32 on both sides. The threaded support sleeve 13 has a retaining groove 31. The retaining groove 31 and the retaining plate through holes 32 are adapted to the retaining plate 30. The retaining plate 30 passes through the retaining plate through holes 32 and is connected to the retaining groove 31. The control rod 22 is threadedly positioned and connected to the control support sleeve 23, so that the locking plate 25 can be driven to make lateral linear displacement by rotating the knob 21. When the locking plate 25 moves inward until the locking block 26 is embedded in the locking groove 27, the support plate 16 can be added to the positioning fulcrum of the lever 28. The lever 28 and the strip plate 34 are synchronously braked and locked. When the locking plate 25 moves outward until the locking block 26 is completely disengaged from the locking groove 27, When the positioning fulcrum of the support plate 16 and the lever 28 disappears, the lever 28 can be used to drive the strip plate 34 to move linearly. When the strip plate 34 moves inward until the clamping plate 30 is embedded in the clamping groove 31, the fixing sleeve 14 can be used to increase the axial positioning fulcrum of the threaded support sleeve 13 to prevent relative rotation between the two and cause the threaded connection to loosen, thus strengthening the connection stability. When the strip plate 34 moves outward until the clamping plate 30 and the clamping groove 31 are completely separated, the positioning fulcrum of the fixing sleeve 14 and the threaded support sleeve 13 disappears. At this time, the threaded support sleeve 13 and the pipe 01 can be quickly separated from the fixing sleeve 14 by rotating the rotating sleeve 12 without the need for professional tools. This improves the efficiency of disassembly, assembly and maintenance of petrochemical pipelines, and strengthens the stability of the pipeline connection through double braking and locking, preventing the pipe 01 from loosening due to vibration or pressure fluctuations, thus improving the safety and reliability of petrochemical pipeline transportation.

The outer sliding hole 29 is adapted to the lever 28. The lever 28 passes through the outer sliding hole 29 and the control plate 33 in sequence. The boss 17 is divided into a left boss 171 and a right boss 172. The left boss 171 has a limiting sliding hole 20. The lever 28 has a limiting rod groove 19. The limiting rod groove 19 and the limiting sliding hole 20 are adapted to the limiting rod 18. The limiting rod 18 passes through the limiting sliding hole 20. The inner end of the limiting rod 18 is connected to the limiting rod groove 19.

[0027] Example 4:

[0028] The lever 28 of this utility model is connected to the outside of the bearing 24. The bearing 24 is connected to the control support rod 22. The outer end of the control support rod 22 has a knob 21, which fits against the lever 28. The control support rod 22 is connected to the inside of the control support sleeve 23 by a thread. The outside of the control support sleeve 23 fits against the lever 28. The outer end of the control support sleeve 23 has a locking plate 25, which is connected to the right boss 172. The right boss 172 has multiple locking grooves 27 on both sides. The locking plate 25 has locking blocks 26 on both sides. The locking blocks 26 are adapted to the locking grooves 27 and are connected to the locking grooves 27. This device strengthens the stability of the pipeline connection through double braking and locking, and prevents the pipeline 01 from loosening due to vibration or pressure fluctuations. It improves the safety, reliability and sealing of petrochemical pipeline transportation, while also being convenient to disassemble and assemble without the need for professional tools, thus improving the efficiency of petrochemical pipeline installation and maintenance.
