Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a pipeline sealing device for gas engineering construction. Background Technology

[0002] During the construction of gas engineering projects, pipeline sealing is a crucial step in ensuring operational safety. In particular, during maintenance, renovation, or sectional pressure testing, reliable pipeline sealing is necessary to prevent gas leaks.

[0003] Chinese patent CN213541657U discloses a gas pipeline sealing device that connects to the pipeline surface via a threaded structure. However, this design relies entirely on the thread for fixation, and the threaded connection is prone to loosening under long-term vibration or external force, resulting in an untight connection between the sealing device and the pipeline, which in turn affects the sealing effect.

[0004] Therefore, a pipeline sealing device for gas engineering construction is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A pipeline sealing device for gas engineering construction includes a first mounting box. A pipeline clamping mechanism for connecting a gas pipeline is mounted on the surface of the first mounting box. An adjusting component for controlling the operation of the pipeline clamping mechanism is also provided on the surface of the first mounting box. A second mounting box is fixedly connected to the right side of the first mounting box. A pressing component is provided on the surface of the second mounting box. A sealing plug is mounted at the bottom of the pressing component. A reinforcing sealing component is provided on the surface of the sealing plug. The reinforcing sealing component includes a rubber airbag, which is fixedly connected to the left end of the sealing plug. A connecting pipe is fixedly inserted into the surface of the rubber airbag. A manual pressure ball is fixedly connected to the end of the connecting pipe.

A first knob is fixedly connected to the top of the first worm gear, and a first worm wheel is fixedly sleeved in the middle of the double-ended screw, with the first worm wheel meshing with the first worm gear.

[0009] Furthermore, the clamping assembly includes a threaded rod, which is rotatably connected to the inner wall of the second mounting box. A U-shaped bracket is threadedly connected to the surface of the threaded rod, and the bottom end of the U-shaped bracket is fixedly connected to a sealing plug. A sliding groove is formed through the bottom surface of the second mounting box, and the inner wall of the sliding groove is slidably connected to the U-shaped bracket.

[0018] like Figures 1 to 4As shown, a pipeline sealing device for gas engineering construction includes a first mounting box 1. A pipeline clamping mechanism 2 for connecting a gas pipeline is mounted on the surface of the first mounting box 1. The pipeline clamping mechanism 2 includes a double-ended screw 201, which is rotatably connected to the inner wall of the first mounting box 1. Connecting rods 202 are threaded to both ends of the double-ended screw 201, and the connecting rods 202 are movably inserted into the first mounting box 1. A clamping plate 203 is fixedly connected to the end of the connecting rod 202. An anti-slip pad 204 is fixedly connected to the surface of the clamping plate 203, and the anti-slip pad 204 is in contact with the surface of the gas pipeline. It should be noted that the double-ended screw 201 can be driven to rotate by the adjusting component 3. Under the action of the threads, the connecting rod 202 can be moved, thereby causing the clamping plate 203 to move, allowing the anti-slip pad 204 to squeeze and adhere to the surface of the gas pipeline, thus connecting with the gas pipeline.

[0019] The surface of the first mounting box 1 is provided with an adjustment component 3 for controlling the operation of the pipe clamping mechanism 2. The adjustment component 3 includes a first worm gear 301, which is rotatably connected to the first mounting box 1. A first knob 302 is fixedly connected to the top of the first worm gear 301, and a first worm wheel 303 is fixedly sleeved on the middle of the double-ended screw 201, and the first worm wheel 303 meshes with the first worm gear 301. More specifically, by rotating the first knob 302, the first worm gear 301 can be controlled to rotate, thereby driving the first worm wheel 303 meshing with it to rotate, which in turn drives the double-ended screw 201 to rotate.

[0020] A second mounting box 4 is fixedly connected to the right side of the first mounting box 1. A clamping component 5 is provided on the surface of the second mounting box 4. The clamping component 5 includes a threaded rod 501, which is rotatably connected to the inner wall of the second mounting box 4. A U-shaped bracket 502 is threadedly connected to the surface of the threaded rod 501. The bottom end of the U-shaped bracket 502 is fixedly connected to the sealing plug 6. A sliding groove 503 is provided through the bottom surface of the second mounting box 4, and the inner wall of the sliding groove 503 is slidably connected to the U-shaped bracket 502. A second worm gear 504 is rotatably connected to the inner wall of the second mounting box 4. A second knob 505 is fixedly connected to the top end of the second worm gear 504. A second worm wheel 506 is fixedly sleeved on the surface of the threaded rod 501, and the second worm wheel 506 meshes with the second worm gear 504. It should be noted that by rotating the second knob 505, the second worm 504 is driven to rotate, which in turn drives the second worm wheel 506 meshing with it to rotate, thereby controlling the rotation of the threaded rod 501. Under the action of the thread, the U-shaped bracket 502 can be driven to slide along the inner wall of the slide groove 503, thereby pushing the sealing plug 6 to the left, so that the sealing plug 6 can block the gas pipeline.

[0021] A sealing plug 6 is installed at the bottom of the sealing assembly 5, and a reinforcing sealing assembly 7 is provided on the surface of the sealing plug 6. The reinforcing sealing assembly 7 includes a rubber airbag 701, and the rubber airbag 701 is fixedly connected to the left end of the sealing plug 6. A connecting tube 702 is fixedly inserted into the surface of the rubber airbag 701, and a manual pressurizing ball 703 is fixedly connected to the end of the connecting tube 702. The connecting tube 702 passes through the inside of the sealing plug 6 and is fixedly connected to the sealing plug 6. More specifically, by squeezing the manual pressurizing ball 703, air is sent into the rubber airbag 701 through the connecting tube 702, causing the rubber airbag 701 to continuously expand, thereby sealing the sealing plug 6 and the inner wall of the gas pipeline using the rubber airbag 701.

[0022] The sealing plug 6 is a frustum-shaped structure with a smaller diameter on the left and a larger diameter on the right. It should be noted that by setting the frustum-shaped sealing plug 6, it is possible to effectively seal gas pipelines of different diameters.

[0023] In summary: By adjusting component 3 to control the operation of pipe clamping mechanism 2, pipe clamping mechanism 2 is connected to gas pipeline. Then, by pressing component 5 to control the movement of sealing plug 6, sealing plug 6 can seal the end of gas pipeline. Subsequently, by strengthening sealing component 7, the inner wall of pipeline can be strengthened to seal. In use, this utility model achieves the effect of effectively sealing gas pipeline and can effectively prevent loosening during use, thereby ensuring sealing stability.
