Description

Technical Field

[0001] The utility model relates to the technical field of gas equipment safety detection, and more specifically to a gas pipe port joint sealing detection device. Background Art

[0002] Gas pipe fittings are key components used to connect gas pipelines, equipment, valves, and other components, ensuring smooth and safe gas flow. Gas pipe fittings, also commonly referred to as "gas pipe connectors" or "gas joints," are an integral part of the gas system. They are primarily used to connect different gas pipelines or to interface between gas pipelines and gas equipment, ensuring the proper delivery and distribution of gas.

[0003] The patent with publication number CN215173096U discloses a multifunctional gas pipe socket, which can be installed in a variety of ways, including a gas pipe fixing block, the right part of the gas pipe fixing block is provided with a fastening groove, the right part of the gas pipe fixing block is matched with the gas pipe, the left end of the gas pipe fixing block is provided with an external connecting circular groove, the left end of the gas pipe fixing block is provided with a hexagonal fixing nut, the right part of the hexagonal fixing nut is provided with an internal connecting circular groove, the external connecting circular groove matches the internal connecting circular groove, the left end of the hexagonal fixing nut is provided with an internal thread, the left end of the hexagonal fixing nut is provided with a socket joint, the left end of the socket joint is provided with a hexagonal boss, the right end of the socket joint is provided with an external thread, the external thread of the right end of the socket joint matches the internal thread of the left end of the hexagonal fixing nut, the right end of the socket joint is provided with a sealing rubber ring, and the right part of the sealing rubber ring is provided with a boss.

[0004] Although the device has many beneficial effects, the following problems still exist: the gas pipe socket can be installed not only through the screw thread, but also through the socket, and there is no need to replace the plug, which makes the installation easier. Gas leakage is one of the most common safety hazards in the gas system. If the gas pipe joint is not sealed tightly, gas may leak from the joint and accumulate indoors or in the surrounding environment. Once it encounters open flames or high temperatures, it may cause a fire or explosion. The existing gas pipeline sealing detection mostly adopts traditional methods, such as using a U-shaped pressure gauge for pressure testing, but this method has problems such as human reading errors, inconvenience in recording, and lack of sanitary protection measures.

The internal thread of the first threaded hole 15 is connected to the closing column 12. The outer surface of the air pump 11 is fixedly installed with an inflation tube 13. The closing column 12 is movably sleeved with the inflation tube 13. The closing column 12 is movably fitted with the inside of one end of the gas pipe. The threaded column 10 is threadedly connected to the second threaded hole 16 on the outer surface of the fixing frame 2. At the same time, the other end of the threaded column 10 is threadedly connected to the interface end of the gas pipe to achieve preliminary fixation of the gas pipe interface.

[0033] Furthermore, the blocking assembly also includes a threaded column 10 and a second threaded hole 16. The outer surface of the fixing frame 2 is provided with a second threaded hole 16. The internal thread of the second threaded hole 16 is connected to the threaded column 10. The threaded column 10 is threadedly connected to the interface end of the gas pipe. The closing column 12 is threadedly connected to the first threaded hole 15 on the outer surface of the air pump 11 and is movably sleeved on the inflation tube 13.

[0034] Furthermore, a drive motor 6 is fixedly installed on the outer surface of the operating table 1, and two bearing seats are fixedly connected to the top of the operating table 1. A turntable 4 is rotatably connected between the two bearing seats. The output end of the drive motor 6 is fixedly connected to the turntable 4, and a connecting column 7 is fixedly connected to the non-center part of the inner part of the turntable 4. The outer surface of the connecting column 7 is rotatably connected to a connecting rod 5, and the connecting rod 5 is rotatably connected to the air pump 11. The output end of the drive motor 6 drives the turntable 4 to rotate, and the connecting column 7 inside the turntable 4 is rotatably connected to the air pump 11 through the connecting rod 5. Therefore, as the turntable 4 rotates, the air pump 11 can move within a certain range inside the fixed frame 2.

[0035] Furthermore, a slot 14 is provided on the top of the operating table 1, and the internal thread of the placement sleeve 3 is connected to a screw rod 8, and the top of the screw rod 8 is fixedly connected to a support plate 9. The support plate 9 is arranged in an arc-shaped structure and is located inside the placement sleeve 3. By adjusting the threaded connection depth of the screw rod 8 inside the placement sleeve 3, the support plate 9 can provide firm support for the gas pipe, thereby ensuring the stability of the gas pipe during the detection process.

[0036] Furthermore, the detection component includes a pressure sensor 17 and a single-chip computer 18. The outer surface of the fixing frame 2 close to the threaded column 10 and the outer surface of the support plate 9 are fixedly installed with the pressure sensor 17. The outer surface of the operating table 1 is fixedly installed with the single-chip computer 18. The single-chip computer 18 is wirelessly connected to the two pressure sensors 17.

The outer surface of the fixed frame 2 close to the threaded column 10 and the outer surface of the support plate 9 are fixedly installed with the pressure sensor 17. The pressure sensor 17 can monitor the pressure changes at the gas pipe interface in real time and transmit the data to the single-chip computer 18. The single-chip computer 18 processes and analyzes the received pressure data.

[0037] Working principle: When the staff needs to use the gas pipe joint sealing detection device, the operator places the gas pipe to be tested and its joint in the placement sleeve 3 inside the fixed frame 2. By adjusting the threaded connection depth of the screw 8 inside the placement sleeve 3, the support plate 9 can firmly support the gas pipe to ensure the stability of the gas pipe during the detection process. Then the threaded column 10 is threadedly connected to the second threaded hole 16 on the outer surface of the fixed frame 2. At the same time, the other end of the threaded column 10 is threadedly connected to the gas pipe interface end to achieve preliminary fixation of the gas pipe interface. The air pump 11 is connected to the inside of the gas pipe through the inflation tube 13 on its outer surface. In order to seal the connection between the gas pipe and the air pump 11, the closing column 12 is threadedly connected to the first threaded hole 15 on the outer surface of the air pump 11 and movably sleeved on the inflation tube 13. The drive motor 6 is started, and the output end of the drive motor 6 drives the turntable 4 to rotate. The connecting column 7 inside the turntable 4 is rotatably connected to the air pump 11 through the connecting rod 5. Therefore, as the turntable 4 rotates, the air pump 11 can move within a certain range inside the fixed frame 2. Press it with your hand. The gas pipe is compressed to fix its position. As the air pump 11 moves, the closing column 12 is docked with the inside of the other end of the gas pipe to form a seal. The air pump 11 is started to inflate the gas pipe to simulate the pressure state of the gas in the pipeline. During the detection process, the outer surface of the fixing frame 2 close to the threaded column 10 and the outer surface of the support plate 9 are fixedly installed with a pressure sensor 17. The pressure sensor 17 can monitor the pressure changes at the gas pipe interface in real time and transmit the data to the single-chip microcomputer 18. The single-chip microcomputer 18 processes and analyzes the received pressure data. If an abnormal pressure is detected (such as a sudden drop in pressure, indicating a possible leak), an alarm message is displayed on the display screen on its outer surface to prompt the operator to perform further inspection and maintenance. After the detection is completed, the air pump 11 is turned off, the inflation is stopped, and the threaded connection between the threaded column 10 and the gas pipe interface end is released by rotating the threaded column 10. At the same time, the closing column 12 is removed to release the sealed connection between the air pump 11 and the gas pipe. The operator can reset the air pump 11 to the initial position by reversing the drive motor 6 to prepare for the next detection.
