Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a pressure pipeline leakage detection device. Background Technology

[0002] Pressure pipelines are tubular devices used to transport fluid media such as gases and liquids under pressure. The media they transport often possess characteristics such as flammability, explosiveness, toxicity, or high temperature and pressure, and are widely used in petrochemical, natural gas, power, metallurgy, and urban gas industries. Pressure pipelines typically require leak detection to ensure their safety during use. Current detection methods involve injecting gas into the pipeline and then using pressure testing to determine if a leak has occurred. However, injecting gas into the pipeline takes a long time, requiring a large amount of test gas. This not only wastes test gas but also results in low detection efficiency due to the lengthy filling, pressure holding, and venting processes. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a pressure pipeline leakage detection device that effectively increases pipeline detection efficiency.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a pressure pipeline leakage detection device, comprising: At least one filling component that can be inserted into the detection channel; The filling component includes a hollow cylinder, one side of which has an air inlet and a detachable plug. The cylinder has a first connecting part and a second connecting part on opposite sides. Two plugging detection components are provided. Each plugging detection component can be connected to a corresponding first or second connecting part and plug both sides of the detection pipe. Each plugging detection component includes an injection component and a detection component. The plugging detection component can inject detection gas into the detection pipe when plugging the detection pipe and detect its internal pressure.

[0005] Furthermore, both the first connecting part and the second connecting part are annular in shape, the diameter of the first connecting part is smaller than the diameter of the second connecting part, the outer wall of the first connecting part is provided with an external thread, and the inner wall of the second connecting part is provided with an internal thread corresponding to the external thread.

[0006] Furthermore, the occlusion detection component includes an occlusion disc, on which a connecting component is provided, which can be connected to the first connecting part or the second connecting part.

[0007] Furthermore, the gas injection component includes a gas injection connector disposed on the side of the sealing disc away from the connecting component, and the sealing disc is provided with a gas injection port communicating with the gas injection connector on the side closer to the connecting component.

[0008] Furthermore, the detection component includes a pressure sensor disposed on the sealing disc, and a probe is disposed at the detection end of the pressure sensor, the probe being located on the side of the sealing disc near the connecting component.

[0009] Furthermore, a sealing ring is provided on the side of the sealing disc near the connecting component.

[0010] Furthermore, it also includes a support assembly, which includes a mounting ring sleeved on the corresponding second connecting part, a telescopic rod provided on the mounting ring, a spring provided inside the telescopic rod for pressing its telescopic end, and a pulley rotatably provided at the telescopic end of the telescopic rod.

[0011] The beneficial effects of this utility model are reflected in: In this invention, a corresponding number of filling components are selected according to the length of the detection pipe, and they are connected to each other through the first connecting part and the second connecting part. Then, the operator pushes the filling component into the detection pipe and installs two sealing detection components on the corresponding filling components. At this time, the two sealing detection components are in close contact with both sides of the detection pipe, thereby forming a closed environment inside the detection pipe. After the operation is completed, detection gas is injected into the detection pipe through the gas injection component, and the detection component detects the internal pressure. The pressure change is used to determine whether there is a leak in the detection pipe. The filling components can occupy more space inside the detection pipe, thereby effectively saving the amount of monitoring gas injected and the injection time, and improving the detection efficiency.

[0014] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figure 1-4 This utility model discloses a pressure pipeline leakage detection device, including at least one filling component 1 and a detection pipeline 4 to be tested. The filling component 1 can be inserted into the detection pipeline 4. The filling component 1 includes a hollow cylinder 11. One side of the cylinder 11 has an air inlet, and a plug 12 is detachably installed at the air inlet. A first connecting part 13 and a second connecting part 14 are respectively installed on opposite sides of the cylinder 11.

[0016] When in use, before testing the test pipe 4, the staff can open the plug 12 and inject air into the inside of the cylinder 11. After the air injection is completed, the plug 12 is installed to form a closed environment inside the cylinder 11.

[0017] In one embodiment, the device further includes two sealing and detection components 2. The sealing and detection components 2 can be connected to the corresponding first connecting part 13 or second connecting part 14, and seal both sides of the detection pipe 4 after the filling component 1 has been inserted into the detection pipe 4. The sealing and detection components 2 include an injection component and a detection component. In use, the sealing and detection components 2 can inject detection gas into the detection pipe 4 after sealing the detection pipe 4, and detect its internal pressure.

[0018] In practice, according to the corresponding length of the detection pipeline 4, a corresponding number of filling components 1 are selected and connected to each other through the first connecting part 13 and the second connecting part 14. Then, the staff pushes the filling component 1 into the detection pipeline 4 and installs two sealing detection components 2 on the corresponding filling component 1. At this time, the two sealing detection components 2 are tightly attached to both sides of the detection pipeline 4, thereby forming a closed environment inside the detection pipeline 4. After the operation is completed, detection gas is injected into the detection pipeline 4 through the gas injection component. At this time, the detection component detects the internal pressure and judges whether there is a leak in the detection pipeline 4 by the pressure change. The setting of the filling component 1 can occupy more space inside the detection pipeline 4, thereby effectively saving the amount of monitoring gas injected and the injection time.

[0019] In addition, pre-injecting air into the cylinder 11 can further reduce the operation time during testing, thus facilitating practical use.

[0020] In one embodiment, both the first connecting part 13 and the second connecting part 14 are annular in shape. The diameter of the first connecting part 13 is smaller than the diameter of the second connecting part 14. The outer wall of the first connecting part 13 is provided with an external thread, and the inner wall of the second connecting part 14 is provided with an internal thread corresponding to the external thread.

[0021] In specific implementation, when multiple cylinders 11 are connected to each other, each pair of adjacent cylinders 11 are screwed together by the external and internal threads on the first connecting part 13 and the second connecting part 14. The amount of screwing can be flexibly adjusted according to the length of the detection pipe 4 so as to facilitate the detection of detection pipes 4 of different lengths.

[0022] In one embodiment, the occlusion detection component 2 includes an occlusion disk 21, on which a connecting component 22 is mounted, and the connecting component 22 can be connected to a first connecting part 13 or a second connecting part 14.

[0023] In practice, the corresponding cylinder 11 that needs to be connected to the corresponding sealing disc 21 will have its corresponding first connecting part 13 or second connecting part 14 close to the sealing disc 21, and the connecting part 22 can adopt the corresponding second connecting part 14 or first connecting part 13, so as to facilitate connection and use.

[0024] In one embodiment, the gas injection component includes a gas injection connector 23 installed on the side of the sealing disc 21 away from the connecting component 22, and a gas injection port 24 communicating with the gas injection connector 23 is installed on the side of the sealing disc 21 near the connecting component 22.

[0025] In practice, when the sealing plate 21 is connected to the corresponding cylinder 11 and seals one side of the detection pipeline 4, the gas injection port 24 is located inside the detection pipeline 4. The staff connects the external pipeline to the gas injection connector 23 and, together with the pump equipment, injects the detection gas into the detection pipeline 4 for subsequent detection.

[0026] In one embodiment, the detection component includes a pressure sensor 25 mounted on the sealing disc 21, and a probe 26 is mounted at the detection end of the pressure sensor 25. The probe 26 is located on the side of the sealing disc 21 near the connecting component 22.

[0027] In specific implementation, when the sealing plate 21 is connected to the corresponding cylinder 11 and seals one side of the detection pipe 4, the probe 26 is located inside the detection pipe 4. When the detection gas is injected into the detection pipe 4, the probe 26 and the pressure sensor 25 can detect the pressure inside the detection pipe 4, which makes it easier for staff to determine whether there is a leak in the detection pipe 4. This pressure detection method is common knowledge in the field, so its specific structure and working principle will not be described in detail in this article.

[0028] In one embodiment, a sealing ring 27 is also installed on the side of the sealing disc 21 near the connecting component 22. The sealing ring 27 may be a silicone or rubber ring.

[0029] In practice, by setting the sealing ring 27, the sealing effect between the sealing plate 21 and the detection pipe 4 can be better, thereby ensuring the accuracy of subsequent detection.

[0030] In one embodiment, the device further includes a support assembly 3, which includes a mounting ring 31 sleeved on the corresponding second connecting portion 14. A telescopic rod 32 is mounted on the mounting ring 31. A spring (not shown in the figure) for pressing its telescopic end is installed inside the telescopic rod 32. A pulley 33 is rotatably mounted at the telescopic end of the telescopic rod 32.

[0031] In practice, the telescopic rod 32 can be extended and retracted to an appropriate amount, and the pulley 33 can be brought into contact with the inner wall of the detection pipe 4, thereby providing support for the corresponding filling component 1. This ensures that the filling component 1 is stable when used inside the detection pipe 4. When the filling component 1 moves, the pulley 33 will also rotate along with it, thus effectively reducing the friction between them.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] Additionally, "multiple" refers to two or more.
