[0002] Natural gas energy not only has the advantages of high thermal quality and few pollutants, but also has the advantages of large-scale and wide-ranging comprehensive applications. In actual applications, natural gas transportation mainly adopts high-pressure transportation, while users mainly use low-pressure natural gas. Therefore, natural gas needs to be pressure-regulated. During the pressure regulation process, the pressure energy generated by the natural gas can be used to generate electricity through the natural gas pipeline network pressure-regulating power generation device.

[0003] Although the existing natural gas pipeline network pressure regulating power generation device can adjust the gas pressure inside the pipeline by opening and closing the baffle, when the distance between the baffle and the inner wall of the pipeline is small, the pressure on the baffle is large, and the baffle will bend after long-term use. In addition, the friction generated by the flow of natural gas will also cause the baffle to wear, reducing the service life of the baffle and affecting the sealing of the baffle and the pipeline when it is closed.

The gear 421 rotates, so that the secondary gear 421 drives the secondary rack 422 to move inside the limit plate 414, and the secondary rack 422 drives the pull rod 407 to move, so that the pull rod 407 drives the telescopic tube 405 to move through the inclined rod 406, so that the telescopic tube 405 is separated from the main extension tube 404 and moves to the inside of the sealing shell 401, and the through hole of the secondary adjustment plate 403 is sealed by a plurality of main baffles 408, and the through hole of the main adjustment plate 402 is sealed by a plurality of secondary baffles 409, thereby The auxiliary baffle 409 can adjust the flow rate of natural gas during its flow, and can also adjust the gas pressure of natural gas during its flow. At the same time, it can also seal the main regulating plate 402 and the auxiliary regulating plate 403, and cut the flowing natural gas through the tips of the main baffle 408 and the auxiliary baffle 409, thereby reducing the resistance generated by the natural gas during its flow, reducing the friction generated by the natural gas with the main baffle 408 and the auxiliary baffle 409 during its flow, thereby increasing the service life of the main baffle 408 and the auxiliary baffle 409, and increasing the sealing performance of the device.

[0027] Secondly, refer to Figure 1 , Figure 2 and Fig.11 As shown, the sealing mechanism includes a filter screen 504 fixed inside the sealing tube 502 and a pressure reducing tube 508 fixed on the natural gas pipeline body 1. A pressure rod 503 is fixed on one side of the filter screen 504. A sealing cover 505 is arranged on the side of the pressure reducing tube 508 away from the natural gas pipeline body 1. A conical block 506 is fixed in the middle of the sealing cover 505. The side of the pressure rod 503 away from the filter screen 504 contacts the side of the sealing cover 505 away from the conical block 506. The telescopic tube 405 drives the sealing tube 502 to move, so that the sealing tube 502 drives the filter screen 504 to move, so that the filter screen 504 drives the pressure rod 503 to move, and the pressure rod 503 pushes the sealing cover 505 to move, so that the sealing cover 505 drives the conical block 506 to move, and the conical block 506 moves to the inside of the pressure reducing pipe 508. At the same time, the sealing cover 505 contacts the end of the pressure reducing pipe 508 away from the natural gas pipeline body 1, so that the sealing cover 505 seals the pressure reducing pipe 508, thereby sealing the natural gas pipeline body 1 to prevent the gas inside the natural gas pipeline body 1 from escaping to the outside.

[0028] By adopting the above technical solution: When in use, the sealing tube 502 is driven to move by the telescopic tube 405, so that the sealing tube 502 drives the filter screen 504 to move, and the filter screen 504 drives the pressure rod 503 to move, and the pressure rod 503 pushes the sealing cover 505 to move, so that the sealing cover 505 drives the conical block 506 to move, and the conical block 506 moves to the inside of the pressure reducing tube 508, and at the same time, the sealing cover 505 contacts the end of the pressure reducing tube 508 away from the natural gas pipeline body 1, so that the sealing cover 505 seals the pressure reducing tube 508, thereby sealing the natural gas pipeline body 1 to prevent the gas inside the natural gas pipeline body 1 from escaping to the outside, thereby further improving the sealing performance of the device.

[0029] Again, reference Fig.11 As shown, an extension portion is provided on the side of the sealing cover 505 away from the pressure rod 503, and a groove matched with the extension portion is provided on the end of the pressure reducing tube 508 away from the natural gas pipeline body 1, and a stopper 507 is fixed on the end of the conical block 506 away from the sealing cover 505, and the stopper 507 is slidably installed inside the pressure reducing tube 508. When the sealing cover 505 contacts the pressure reducing tube 508, the sealing cover 505 drives the extension portion to be inserted inside the groove. The cooperation of the extension portion and the groove can further improve the sealing performance of the sealing cover 505 and the pressure reducing tube 508. At the same time, the conical block 506 drives the stopper 507 to move, so that the stopper 507 contacts one end of the inner wall of the pressure reducing tube 508, and the stopper 507 is limited by the pressure reducing tube 508, so that the stopper 507 limits the sealing cover 505 through the conical block 506, so as to prevent the sealing cover 505 from falling into the inside of the bellows 501, thereby failing to seal the pressure reducing tube 508, thereby improving the safety of the device.

[0030] By adopting the above technical solution: When in use, the sealing cover 505 drives the extension part to be inserted into the inside of the groove. The cooperation of the extension part and the groove can further improve the sealing performance of the sealing cover 505 and the pressure reducing tube 508. At the same time, the conical block 506 drives the shift rod 507 to move, so that the shift rod 507 contacts one end of the inner wall of the pressure reducing tube 508, and the shift rod 507 is limited by the pressure reducing tube 508. The shift rod 507 limits the sealing cover 505 through the conical block 506, so as to prevent the sealing cover 505 from falling into the inside of the bellows 501, thereby failing to seal the pressure reducing tube 508 and improving the safety of the device.

[0031] Finally, reference Figure 1 , Figure 2 and Figure 3 As shown, a motor 426 is fixed to the outer wall of the sealing shell 401, a power gear 424 is fixed to the output end of the motor 426, and a gear ring 425 meshing with the power gear 424 is fixed to the outer wall of the auxiliary adjustment plate 403. The power gear 424 is driven to rotate by the output end of the motor 426, so that the power gear 424 cooperates with the gear ring 425 to drive the auxiliary adjustment plate 403 to rotate, so that the rotation of the auxiliary adjustment plate 403 can be controlled by remotely controlling the start and stop of the motor 426, and workers do not need to manually rotate the auxiliary adjustment plate 403, saving time and effort.

[0032] By adopting the above technical solution: When in use, the power gear 424 is driven to rotate by the output end of the motor 426, so that the power gear 424 cooperates with the gear ring 425 to drive the auxiliary adjustment plate 403 to rotate, so that the rotation of the auxiliary adjustment plate 403 can be controlled by remotely controlling the start and stop of the motor 426, and workers do not need to manually rotate the auxiliary adjustment plate 403, saving time and effort.

[0033] 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.
