Description

Technical Field

[0001] This utility model relates to the field of natural gas transmission technology, specifically a natural gas transmission pipeline connection device. Background Technology

[0002] Natural gas transportation refers to the process of transporting natural gas from production sites to consumption sites via pipelines. The primary method of natural gas transportation is through gas pipelines, which offers advantages such as high efficiency, environmental friendliness, and safety. During transportation, it is crucial to ensure the natural gas's sealing performance to prevent the risk of leakage.

[0003] Existing natural gas pipelines typically use flanges for connection. During installation, bolt holes need to be aligned, but misalignment is common, requiring multiple alignments. This process is cumbersome and results in poor sealing at the connection points, making it inconvenient to use. Therefore, we propose a natural gas pipeline connection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a natural gas pipeline connection device, which solves the problems of natural gas pipelines typically using flanges for connection, requiring bolt holes to be aligned before installation, which can easily lead to misalignment between bolt holes during installation, necessitating multiple alignments, making the operation cumbersome, and resulting in poor sealing at the pipeline connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A natural gas transmission pipeline connection device includes a first transmission pipeline and a second transmission pipeline. A second flange is fixedly connected to one end of the second transmission pipeline. A fixing block is symmetrically fixedly connected to one side of the second flange. A locking block is slidably connected inside the fixing block, and a spring is provided between the locking block and the fixing block. A first flange is fixedly connected to one end of the first transmission pipeline. A positioning block is symmetrically fixedly connected to one side of the first flange. The positioning block has a groove inside that cooperates with the locking block. An adjusting ring is slidably connected to the outer side of the first transmission pipeline. A connecting block is symmetrically fixedly connected to the outer side of the adjusting ring. A protective ring is fixedly connected to one end of the connecting block, and the inner wall of the protective ring is provided with… The first sealing ring: When connecting pipes, the positioning block is aligned with the fixing block and pushed. Since one side of the locking block is inclined, it will squeeze and drive the locking block to move during the movement of the positioning block. The spring is compressed. When the positioning block and the fixing block are close together, the spring will drive the locking block to move and reset due to the elastic force, so that the locking block enters the inside of the locking groove, thereby limiting and fixing the position of the positioning block. It can pre-position the first flange and the second flange, which is convenient for subsequent installation and fixing of the flanges with bolts. The adjusting ring and the connecting block drive the protective ring to move to the connection of the first flange and the second flange. The setting of the first sealing ring can enhance the sealing effect of the pipe connection.

[0006] Preferably, a sliding rod is slidably connected inside the fixed block, the locking block is fixedly connected to the sliding rod, and an unlocking block is fixedly connected to the end of the sliding rod away from the locking block. The unlocking block drives the sliding rod to move, and the sliding rod moves with the locking block.

[0007] Preferably, an annular frame is fixedly connected to the outer side of the first conveying pipe, and support blocks are symmetrically fixedly connected to the inner wall of the annular frame. A worm gear is rotatably connected to one side of the support block, and a lead screw is symmetrically fixedly connected to one side of the adjusting ring. The lead screw is threadedly connected to the worm gear. The rotation of the worm gear drives the lead screw to move, and the lead screw drives the adjusting ring to move.

[0008] Preferably, a connecting ring is fixedly connected to one side of the worm gear, and a gear is fixedly connected to the end of the connecting ring away from the worm gear. An internal gear ring that cooperates with the gear is rotatably connected to the inner wall of the annular frame. The worm gear drives the gear to rotate through the connecting ring, the gear drives the internal gear ring to rotate, and the rotation of the internal gear ring drives another gear to rotate. The other gear drives another worm gear to rotate through the connecting ring.

[0009] Preferably, a worm gear is rotatably connected inside the annular frame, and one of the worm wheels is rotatably connected to the worm gear. A knob is fixedly connected to one end of the worm gear, and the worm gear drives one of the worm wheels to rotate.

[0010] Preferably, the inner wall of the first flange is provided with a second sealing ring, which can be used to seal the connection of the pipeline.

[0015] 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.

[0016] Please see Figures 1 to 7 This utility model provides a technical solution: A natural gas transmission pipeline connection device includes a first transmission pipeline 1 and a second transmission pipeline 4. A second flange 5 is fixedly connected to one end of the second transmission pipeline 4. A fixing block 3 is symmetrically fixedly connected to one side of the second flange 5. A locking block 22 is slidably connected inside the fixing block 3. A spring 23 is provided between the locking block 22 and the fixing block 3. A first flange 2 is fixedly connected to one end of the first transmission pipeline 1. A positioning block 18 is symmetrically fixedly connected to one side of the first flange 2. A locking groove 20 that cooperates with the locking block 22 is provided inside the positioning block 18. An adjusting ring 8 is slidably connected to the outside of the first transmission pipeline 1. A connecting block 10 is symmetrically fixedly connected to the outside of the adjusting ring 8. A protective ring 6 is fixedly connected to one end of the connecting block 10. A first sealing ring 9 is provided on the inner wall of the protective ring 6. During the connection, the positioning block 18 is aligned with the fixing block 3 and pushed. Since one side of the locking block 22 is inclined, the positioning block 18 will squeeze and drive the locking block 22 to move during the movement. The spring 23 is compressed. When the positioning block 18 and the fixing block 3 are close together, the spring 23 will drive the locking block 22 to move and reset due to the elastic force, so that the locking block 22 enters the interior of the locking groove 20, thereby limiting and fixing the position of the positioning block 18. This can pre-position the first flange 2 and the second flange 5, which is convenient for subsequent installation and fixing of the flanges with bolts. The adjusting ring 8 and the connecting block 10 drive the protective ring 6 to move to the connection of the first flange 2 and the second flange 5. The setting of the first sealing ring 9 can enhance the sealing effect of the pipe connection.

[0017] Furthermore, a sliding rod 21 is slidably connected inside the fixed block 3, and a locking block 22 is fixedly connected to the sliding rod 21. An unlocking block 24 is fixedly connected to the end of the sliding rod 21 away from the locking block 22. The unlocking block 24 drives the sliding rod 21 to move, and the sliding rod 21 moves with the locking block 22.

[0018] Furthermore, an annular frame 7 is fixedly connected to the outer side of the first conveying pipe 1, and a support block 15 is symmetrically fixedly connected to the inner wall of the annular frame 7. A worm gear 13 is rotatably connected to one side of the support block 15, and a lead screw 11 is symmetrically fixedly connected to one side of the adjusting ring 8. The lead screw 11 is threadedly connected to the worm gear 13. The rotation of the worm gear 13 drives the lead screw 11 to move, and the lead screw 11 drives the adjusting ring 8 to move.

[0019] Furthermore, a connecting ring 17 is fixedly connected to one side of the worm gear 13, and a gear 16 is fixedly connected to the end of the connecting ring 17 away from the worm gear 13. An internal gear ring 14 that cooperates with the gear 16 is rotatably connected to the inner wall of the annular frame 7. The worm gear 13 drives the gear 16 to rotate through the connecting ring 17, and the gear 16 drives the internal gear ring 14 to rotate. The rotation of the internal gear ring 14 drives another gear 16 to rotate, and the other gear 16 drives another worm gear 13 to rotate through the connecting ring 17.

[0020] Furthermore, a worm gear 12 is rotatably connected inside the annular frame 7, and one of the worm wheels 13 is rotatably connected to the worm gear 12. A knob is fixedly connected to one end of the worm gear 12, and the worm gear 12 drives one of the worm wheels 13 to rotate.

[0021] Furthermore, the inner wall of the first flange 2 is provided with a second sealing ring 19, which can be used to seal the connection of the pipeline.

[0022] In use, when connecting pipes, the positioning block 18 is aligned with the fixing block 3 and pushed. Since one side of the locking block 22 is inclined, the positioning block 18 will squeeze and drive the locking block 22 to move during its movement, compressing the spring 23. When the positioning block 18 and the fixing block 3 are pressed together, the spring 23 will drive the locking block 22 to move and reset due to its elasticity, so that the locking block 22 enters the interior of the locking groove 20, thereby limiting and fixing the position of the positioning block 18. This can pre-position the first flange 2 and the second flange 5, facilitating the subsequent installation and fixing of the flanges with bolts. Rotating the worm gear 12 will drive one of the worm wheels 13 to rotate. The worm gear 13 drives the gear 16 to rotate via the connecting ring 17. The gear 16 drives the internal gear ring 14 to rotate. The rotation of the internal gear ring 14 drives another gear 16 to rotate. The other gear 16 drives another worm gear 13 to rotate via the connecting ring 17. Since the worm gear 13 and the lead screw 11 are connected by a thread, the rotation of the worm gear 13 can drive the lead screw 11 to move. The lead screw 11 drives the protective ring 6 to move via the adjusting ring 8 and the connecting block 10, so that it moves to the connection between the first flange 2 and the second flange 5. The setting of the first sealing ring 9 can enhance the sealing effect at the pipe connection. It is convenient to operate and use.
