Description

Technical Field

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

[0002] Natural gas, as a clean and efficient energy source, is widely used in urban residential life, commercial venues, and industrial production. Gas pipelines are key infrastructure for transporting natural gas, and their safety and reliability are directly related to the stability of gas supply and the safety of users.

[0003] However, as gas pipelines age, some pipelines may experience aging and corrosion. During maintenance and repair, it is difficult to completely shut down the pipeline. When using traditional sealing devices (such as sealing heads or sealing balls) to seal the pipeline, it is difficult to achieve a reliable seal under pressure, which can easily lead to leakage. Furthermore, it is difficult to automatically adjust the sealing state according to changes in pipeline pressure and flow, making it difficult to adapt to dynamic operating conditions and unable to automatically protect the sealing device and pipeline when the pressure is too high.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a gas pipeline sealing device.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0009] Preferably, the pressure relief component further includes an electric actuator disposed outside the seamless pipe, a guide seat is fixedly connected to the outside of the seamless pipe, and a U-shaped push block is slidably connected to the guide seat.

[0010] Preferably, the sides of the first sector plate and the second sector plate are respectively attached to the inner wall of the seamless pipe, the first driving rod is rotatably connected to the bottom of the U-shaped push block, the second driving rod is rotatably connected to the top of the U-shaped push block, and the U-shaped push block is fixedly connected to the output end of the electric push rod.

[0011] Preferably, the seamless pipe is provided with an adjustment component, the adjustment component including a circular ring threaded to the outside of the seamless pipe, a toothed ring fixedly connected to the side of the circular ring, a collar sleeved on the outside of the circular ring, and a driving component provided on the collar.

[0012] Preferably, the driving component includes a motor fixedly connected to the top of the collar, and a gear fixedly connected to the output end of the motor, the gear meshing with the gear ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model incorporates a rubber ring. When the device is inserted into a gas pipeline, the rubber ring deforms under pressure, adhering to the inner wall of the gas pipeline to form a reliable seal. The pressure relief component remains closed, effectively preventing gas leakage. Furthermore, a pressure sensor monitors the pipeline pressure in real time. When the pressure exceeds a set value, the pressure relief component automatically opens, releasing excess pressure.

[0015] 2. This utility model, by setting an adjustment component, starts the motor, and the gear at the output end of the motor meshes with the gear ring, driving the circular ring to rotate. The rotation of the circular ring, through the action of the thread, drives the collar to squeeze the gasket and rubber ring, causing the gasket and rubber ring to move axially along the seamless pipe. By adjusting the rotation direction and speed of the motor, the position and pressure of the gasket and rubber ring can be controlled to adapt to gas pipes of different diameters.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 6As shown, a gas pipeline sealing device includes a seamless pipe 1, with a conical block 11 at one end, the seamless pipe 1 and the conical block 11 being connected. The seamless pipe 1 has threads on its exterior. A sealing assembly 2 is mounted on the seamless pipe 1, comprising multiple gaskets 21 disposed on the exterior of the seamless pipe 1, with a rubber ring 22 between every two gaskets 21. A pressure sensor 23 is fixedly connected to the exterior of the seamless pipe 1. A pressure relief component 24 is mounted on the seamless pipe 1. The seamless pipe 1, as the core component of the entire sealing device, connects to the gas pipeline and supports other components. The conical block 11 facilitates... The tapered design helps guide the seamless pipe 1 into the gas pipeline and provides an initial seal. The sealing component 2 is used to seal the gas pipeline to prevent gas leakage. The gasket 21 provides support and sealing. The rubber ring 22 can deform under pressure and fit against the inner wall of the gas pipeline to achieve a seal. The pressure sensor 23 is a plastic-encapsulated SOP8 chip pressure sensor manufactured by Wuxi Chuanggan Motor Technology Co., Ltd. It is used to monitor the pressure in the pipeline in real time and provide a signal to the pressure relief component 24. When the pressure in the pipeline exceeds the set value, the pressure relief channel is automatically opened to prevent the pipeline from being damaged due to excessive pressure.

[0027] Specifically, the pressure relief component 24 includes a sleeve 241 disposed inside the seamless pipe 1. A first sector plate 242 is fixedly connected to the outside of the sleeve 241. A first driving rod 243 is fixedly connected to one end of the sleeve 241 outside the seamless pipe 1. A connecting rod 244 is rotatably connected inside the sleeve 241. A second sector plate 245 is fixedly connected to the outside of the connecting rod 244. A second driving rod 246 is fixedly connected to the end of the connecting rod 244. The sleeve 241 is used to accommodate the first sector plate 242 and the connecting rod 244. Both the first sector plate 242 and the second sector plate 245 are in contact with the inner wall of the seamless pipe 1, playing a role in sealing and controlling pressure relief. The first driving rod 243 is used to connect the first sector plate 242 and the U-shaped push block 249 for transmitting power. The connecting rod 244 is used to connect the second sector plate 245 and the second driving rod 246. The second driving rod 246 is used to connect the second sector plate 245 and the U-shaped push block 249 for transmitting power.

[0028] Furthermore, the pressure relief component 24 also includes an electric actuator 247 disposed outside the seamless pipe 1. A guide seat 248 is fixedly connected to the outside of the seamless pipe 1, and a U-shaped push block 249 is slidably connected to the guide seat 248. The electric actuator 247 controls the movement of the U-shaped push block 249 through its extension and retraction. The guide seat 248 is used to support and guide the U-shaped push block 249. The U-shaped push block 249 is connected to the output end of the electric actuator 247. By moving, it drives the first sector plate 242 and the second sector plate 245 to rotate, thereby realizing the opening and closing of the pressure relief channel.

[0029] Furthermore, the sides of the first sector plate 242 and the second sector plate 245 are respectively attached to the inner wall of the seamless pipe 1, the first driving rod 243 is rotatably connected to the bottom of the U-shaped push block 249, the second driving rod 246 is rotatably connected to the top of the U-shaped push block 249, and the U-shaped push block 249 is fixedly connected to the output end of the electric push rod 247.

[0030] As shown above, when the seamless pipe 1 is inserted into the gas pipeline, the conical block 11 guides the seamless pipe 1 into the pipeline opening. Multiple rubber rings 22 can deform under pressure and fit onto the inner wall of the gas pipeline to achieve a seal. The pressure sensor 23 monitors the pressure inside the pipeline in real time. When the pressure exceeds the set value, the electric actuator 247 is activated, pushing the U-shaped push block 249 to move. The U-shaped push block 249 drives the sleeve 241 and the connecting rod 244 to rotate in opposite directions through the first driving rod 243 and the second driving rod 246 connected to it. This causes the first sector plate 242 and the second sector plate 245 to rotate, opening the pressure relief channel and releasing excess pressure. When the pressure returns to normal, the electric actuator 247 moves in the opposite direction, closing the pressure relief channel and restoring the sealing state. This effectively prevents gas leakage. By setting the pressure sensor 23, the pressure relief component 24 can automatically open and release excess pressure, which not only protects the sealing device itself but also prevents pipeline damage or leakage caused by excessive pressure, thus improving operational safety.

[0031] Example 2:

[0032] Please see Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that an adjustment component 3 is provided on the seamless pipe 1. The adjustment component 3 includes a circular ring 31 threaded to the outside of the seamless pipe 1. A toothed ring 32 is fixedly connected to the side of the circular ring 31. A collar 33 is sleeved on the outside of the circular ring 31. A driving component 34 is provided on the collar 33. The circular ring 31 is used to install the toothed ring 32 and the collar 33. The toothed ring 32 meshes with the gear 342 to transmit the power of the motor 341. The collar 33 is used to install the motor 341 and to compress the gasket 21.

[0033] Specifically, the driving component 34 includes a motor 341 fixedly connected to the top of the collar 33. A gear 342 is fixedly connected to the output end of the motor 341. The gear 342 meshes with the gear ring 32. The motor 341 provides power to the gear 342, and the gear 342 transmits power to the gear ring 32, thereby driving the circular ring 31 to rotate. The collar 33 moves accordingly, squeezing the gasket 21, thereby adjusting the position and pressure of the gasket 21 and the rubber ring 22.

[0034] As can be seen from the above, when the motor 341 is started, the gear 342 at the output end of the motor 341 meshes with the gear ring 32, driving the circular ring 31 to rotate. The rotation of the circular ring 31, through the action of the thread, drives the collar 33 to squeeze the gasket 21 and the rubber ring 22, causing the gasket 21 and the rubber ring 22 to move axially along the seamless pipe 1. By adjusting the rotation direction and speed of the motor 341, the position and pressure of the gasket 21 and the rubber ring 22 can be controlled to adapt to gas pipes of different diameters. After the adjustment is completed, the motor 341 is stopped, and the sealing component 2 remains in the set position, completing the sealing.
