Description

Technical Field

[0001] This utility model relates to the field of rotary compensator technology, and in particular to a safe explosion-proof self-sealing rotary compensator. Background Technology

[0002] Pipelines are often damaged by external forces. Pipeline compensation is designed to prevent excessive stress, damage, or leakage caused by factors such as thermal expansion and contraction, displacement, or vibration, ensuring the safe and reliable operation of the pipeline system. Through compensators or natural compensation methods, changes in pipeline length and displacement can be absorbed, preventing damage to equipment, supports, and connections.

[0003] The safety-type explosion-proof self-sealing rotary compensator is a pipeline compensation device with a dual-sealing structure. It combines annular and end-face sealing to ensure leak-free sealing under high pressure and high temperature environments. Its structure includes a rotating cylinder, sealing seat, clamping bolts, sealing gland, ball bearings, and rotating core tube. The seal is maintained by spring tension and packing compression, while also possessing excellent compensation capability and pressure resistance.

[0004] Although existing safe explosion-proof self-sealing rotary compensators can meet the needs of most pipelines, after long-term use, the compensators are no longer able to self-fill the pipeline and cannot be quickly and efficiently disassembled for replacement. Therefore, a safe explosion-proof self-sealing rotary compensator is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a safe explosion-proof self-sealing rotary compensator, including an explosion-proof pipe 2. The stainless steel material of the explosion-proof pipe 2 prevents violent explosions. A connecting mechanism is installed on the outside of the explosion-proof pipe 2, allowing for quick replacement, installation, and maintenance of the equipment. An auxiliary pipe 3 is slidably connected to the inside of the connecting mechanism, allowing for docking with other equipment. A sealing ring 5 is fixedly connected to the outside of the explosion-proof pipe 2 to prevent pipe leakage. The auxiliary pipe 3 is slidably connected to the inside of the sealing ring 5. A sealing component is installed on the outside of the auxiliary pipe 3 to seal the connection and prevent leakage. A snap-fit ​​mechanism is installed on the outside of the sealing component to make the sealing component more stable and convenient. The connecting mechanism includes a sliding component and a fixed component. The sliding component includes a connecting pipe 10, which protects the explosion-proof pipe 2 and the auxiliary pipe 3 internally, preventing corrosion from rainwater and other substances. The connecting pipe 10 is slidably connected to the outside of the explosion-proof pipe 2 and the auxiliary pipe 3. Moving ring blocks 1 are slidably connected to the outside of both ends of the connecting pipe 10. For easy driving, positioning blocks 7 are fixedly connected to both ends of the connecting pipe 10. The positioning blocks 7 prevent excessive displacement of the moving ring block 1, which could cause damage. Springs 6 are fixedly connected to both outer ends of the connecting pipe 10. The springs 6 allow the moving ring block 1 to quickly return to its original position due to elasticity, improving work efficiency. The ends of the two springs 6 are fixedly connected to the inner sides of the two moving ring blocks 1. The fixing assembly includes multiple locking blocks 9, all located inside the connecting pipe 10. The locking blocks 9 secure the explosion-proof pipe 2 and the auxiliary pipe 3, and the two moving ring blocks... Block 1 is slidably connected to the outside of multiple locking blocks 9. Both the explosion-proof pipe 2 and the auxiliary pipe 3 are fixedly connected to the outside of the locking blocks 9. The locking blocks 8 are interlocked with each other. The locking blocks 8 can also tightly fix the explosion-proof pipe 2 and the auxiliary pipe 3 when the pipe expands. One end of the explosion-proof pipe 2 is provided with a slot 12. One end of the auxiliary pipe 3 is fixedly connected with a plug rod 11. The plug rod 11 is interlocked with the slot 12. By inserting the plug rod 11 into the slot 12, the explosion-proof pipe 2 and the auxiliary pipe 3 can not only be tightly fixed, but also prevent incomplete sealing.

[0033] Reference Figures 1-4The sealing assembly includes two arc-shaped sealing plates 4, which are disposed on the outside of the auxiliary pipe 3. The arc-shaped sealing plates 4 clamp the auxiliary pipe 3 and other connected equipment. One arc-shaped sealing plate 4 is rotatably connected to one end of the other arc-shaped sealing plate 4. One end of one arc-shaped sealing plate 4 is fixedly connected to an auxiliary plate 13, and one end of the other arc-shaped sealing plate 4 is fixedly connected to an auxiliary plate 24. Other components are connected through the auxiliary plates 13 and 24. The latching mechanism includes a plug-in assembly and a stabilizing assembly. The plug-in assembly includes a housing 18, which protects internal parts from damage. The housing 18 is fixedly connected to the outside of the auxiliary plate 24. A pin 22 is slidably connected inside the housing 18 for fixation. The sleeve is equipped with a second spring 20, which is used to return the pin 22 to its original position. A limit block 19 is fixedly connected to the outside of the pin 22 to prevent the pin 22 from being ejected due to excessive elasticity. The stabilizing component includes a plate 15, which assists the pin 22 in being inserted into the socket 16 for fixation. The plate 15 is fixedly connected to the outside of the auxiliary plate 13, and the socket 16 is opened in the middle of the plate 15. The pin 22 and the socket 16 are interlocked. A pull ring 21 is fixedly connected to one end of the pin 22. The circular pull ring 21 makes it easier for the user to operate. The pull ring 21 is circular. A groove 17 is opened on the outside of the auxiliary plate 14, and the plate 15 is located inside the groove 17. The groove 17 is used to limit the position of the pin 22 and prevent it from being mispositioned.

[0034] Working principle: First, when it is necessary to install or disassemble the explosion-proof pipe 2 and the auxiliary pipe 3 for maintenance, by moving the moving ring block 1 to both sides and squeezing the spring 6, the locking block 9 inside the connecting pipe 10 will retract into the connecting pipe 10. Then, insert the explosion-proof pipe 2 and insert the insertion rod 11 into the insertion hole 16 to secure it. Since there is a sealing ring 5 on the outside of the explosion-proof pipe 2 and the auxiliary pipe 3, the two will be tightly connected. Then, release the hand. Due to the elasticity of the spring 6, the moving ring block 1 will quickly return to the center and squeeze the locking block 9, which will be inserted into the collar 8 on the outside of the explosion-proof pipe 2 and the auxiliary pipe 3, thus tightly and quickly connecting the explosion-proof pipe 2 and the auxiliary pipe 3.

[0035] Secondly, when it is necessary to fix the auxiliary pipe 3 to the corresponding facilities, simply put the two arc-shaped sealing plates 4 on the outside of the corresponding equipment and the auxiliary pipe 3, and then pull the pin 22 inside the outer shell 18 of the auxiliary plate 2 14. Since the limiting block 19 moves with the pin 22, it will squeeze the spring 20. Then rotate one of the arc-shaped sealing plates 4 so that the insert plate 15 on the auxiliary plate 1 13 rotates to below the groove 17 until it can no longer rotate. At this time, release the hand that pulls the pull ring 21. Due to the elasticity of the spring 20, the pin 22 will immediately return to the center and insert into the insertion hole 16 on the insert plate 15, thus firmly fixing the two arc-shaped sealing plates 4 to the outside of the auxiliary pipe 3 and the corresponding equipment to prevent leakage.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
