Description

Technical Field

[0001] This application relates to the field of pipeline inspection technology, and more specifically, to an inspection device for inspecting pipelines. Background Technology

[0002] Pipeline airtightness testing is an indispensable and crucial step in industrial production, energy transmission, and water conservancy projects, ensuring the safety and reliability of pipeline systems. With the rapid development of pipeline inspection technology, the demand for airtightness testing is increasing, especially in terms of efficiency and accuracy. However, existing pipeline airtightness testing equipment still exhibits limitations in terms of automation, testing accuracy, ease of operation, and adaptability to various scenarios, making it difficult to fully meet the modern industrial demand for efficient and intelligent testing equipment.

[0003] A search revealed a pipeline airtightness testing device with Chinese patent publication number CN114923643B, published on July 25, 2025. This patent achieves automated detection of the airtightness of the tested pipeline through a combination of a frame, a differential pressure detection combined isolation valve, and a differential pressure detection sensor. Airtightness is determined by comparing the pressure difference between the tested and a standard pipeline. However, due to the configuration of multiple differential pressure detection combined isolation valves and differential pressure detection sensors, the overall structure of this device is relatively complex, which increases manufacturing costs and maintenance difficulty to some extent. Furthermore, this device primarily relies on differential pressure detection methods, which have limited sensitivity for detecting minute leaks in practical applications, potentially affecting the accuracy of the detection results. It also cannot visually display the specific location of the leak.

[0004] The above situation indicates that existing pipeline airtightness testing equipment still has room for improvement in terms of structural design, detection sensitivity, multi-specification adaptability, and leak point location capabilities. Summary of the Invention

[0036] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0037] This invention provides a testing device for inspecting pipelines, the structure and operating principle of which are described in the appendix. Figure 1 To be continued Figure 10 A detailed description has been provided. The specific embodiments of the present invention will be described in detail below with reference to the specific component numbers marked in the accompanying drawings.

[0038] like Figures 1 to 4 As shown, the core components of this testing equipment include a frame 1, a liquid storage tank 5, a drive assembly, a flow distribution assembly, and a control assembly. The frame 1 serves as the main framework of the entire equipment, and its top is equipped with at least one openable maintenance cover 2 for easy daily maintenance and repair. Multiple liquid outlet ports 3 and liquid return ports 4 are arranged on the outer side of the frame 1. These ports are connected to the internal flow distribution assembly via pipelines, ensuring that the liquid medium can circulate between the equipment and external pipelines.

[0039] The liquid storage tank 5 is fixedly installed inside the frame 1. A filter device 18 is located at its lower part. The filter device 18 is connected to the vortex pump 6 and the gas-liquid booster pump 7 via pipes of different diameters to ensure that the liquid medium entering the pump body is clean and free of impurities. An adjusting device 19 is located at the upper part of the liquid storage tank 5. The adjusting device 19 is connected to the gas-liquid booster pump 7 via pipes for adjusting the pressure of the liquid medium. A drain port is also provided at the bottom of the liquid storage tank 5 for regular cleaning of accumulated impurities or waste liquid. Figure 6 As shown, the internal structure of the liquid storage tank 5 is reasonably designed, which can effectively meet the needs of liquid media storage, filtration and pressure regulation.

[0040] The drive assembly includes a vortex pump 6 and a gas-liquid booster pump 7 housed inside the frame 1. The vortex pump 6 is connected to the outlet of the liquid storage tank 5 via a pipeline, while the gas-liquid booster pump 7 is connected to the outlet of the vortex pump 6 via a pipeline. The outlets of both the vortex pump 6 and the gas-liquid booster pump 7 are connected to check valves 27 via pipelines. The outlets of each check valve 27 are centrally connected to multiple inlets of a multi-port switching valve 28 to prevent backflow of liquid. Figure 5 , Figure 8 and Figure 9 As shown, the combined design of the one-way valve 27 and the multi-way switching valve 28 ensures the safety and stability of the liquid flow path.

[0041] The diversion assembly includes an outlet diversion plate 8 and a return diversion plate 9, both housed inside the frame 1. The outlet diversion plate 8 is connected to the outlet port 3 via a manual valve 10, and the return diversion plate 9 is connected to the return port 4 via a manual valve 10. The diversion assembly also includes multiple gas collection tanks 25 and multiple pressure gauges 26. The gas collection tanks 25 are mounted on the outlet diversion plate 8 and contain pressure sensors. The pressure gauges 26 are mounted on the return diversion plate 9. Figure 7 As shown, multiple ball valves 12 are installed on the outlet flow divider 8 and the return flow divider 9, respectively. The flow meter 11 is connected to the ball valves 12 through pipelines to monitor the liquid flow rate and adjust the flow velocity in real time. The design of the flow divider assembly allows the liquid medium to flexibly switch the flow path as needed, thereby adapting to the detection requirements of pipelines of different specifications.

[0042] The control components include an operation panel 13 mounted on a rack 1, a logic controller 14 disposed inside the rack 1, and a data processing unit 15. The operation panel 13 is electrically connected to the logic controller 14, the logic controller 14 is electrically connected to the data processing unit 15, and the gas-liquid booster pump 7 and the vortex pump 6 are respectively electrically connected to the operation panel 13. Figure 3 and Figure 10 As shown. The logic controller 14 integrates high-voltage protection circuits and overload protection circuits to ensure the safe operation of the equipment.

[0043] An air inlet 20 is also provided on one side of the frame 1. The air inlet 20 is connected to the air pressure sensor 21 and the air source triplet 22 in sequence through the pipeline. The air pressure sensor 21 is connected to the logic controller 14 through the signal line to provide stable air source support for the equipment.

[0044] The control assembly also includes a multi-position solenoid valve group 23 and an air pressure regulating valve 24. The multi-position solenoid valve group 23 is connected to the air pressure regulating valve 24 and the air supply triplet 22 via pipelines. The air pressure regulating valve 24 is connected to the gas-liquid booster pump 7 via pipelines. In addition, the control assembly includes a power switch, a running indicator light, and an emergency stop button. The power switch and the emergency stop button are connected to a circuit breaker via wires to ensure that the power supply can be quickly cut off in case of abnormal conditions.

[0045] The alarm component includes a multi-color indicator light 16 and a built-in audible and visual alarm 17. The multi-color indicator light 16 is connected to the logic controller 14 via signal lines. Figure 3 and Figure 4 As shown, when an abnormal situation occurs during equipment operation, the logic controller 14 will trigger the alarm component to issue an audible and visual alarm, reminding the operator to handle the situation promptly. The design of the alarm component enhances the safety and reliability of the equipment.

[0046] The bottom of frame 1 is equipped with multiple locking casters for easy movement and positioning of the equipment. Ventilation openings are located on both sides of frame 1, with dust filters embedded within to ensure good heat dissipation and dust protection during operation. Handles are also provided on both sides of frame 1 for easy maneuvering of the equipment. Figure 1 and Figure 2 As shown. The bottom structure design of rack 1 fully considers the portability and practicality of the equipment.

[0047] The working process of the detection equipment is as follows: First, the operator starts the equipment through the operation panel 13. After receiving the start signal, the logic controller 14 controls the vortex pump 6 and the gas-liquid booster pump 7 to start working. The vortex pump 6 draws liquid medium from the storage tank 5 and delivers the liquid to the gas-liquid booster pump 7 through the pipeline. After the gas-liquid booster pump 7 pressurizes the liquid medium, it is delivered to the outlet diversion plate 8 through the one-way valve 27 and the multi-way switching valve 28. The manual valve 10 on the outlet diversion plate 8 is opened or closed as needed to distribute the liquid medium to different outlet ports 3, and then flows into the pipeline to be tested. After circulating in the pipeline, the liquid returns to the return diversion plate 9 through the return port 4. The manual valve 10 on the return diversion plate 9 is also adjusted as needed to reintroduce the liquid medium into the storage tank 5. During this process, the flow meter 11 monitors the liquid flow rate in real time and transmits the data to the logic controller 14. The logic controller 14 analyzes the flow data through the data processing unit 15 to determine whether there is a leak in the pipeline. If an abnormality is detected, the logic controller 14 will trigger the alarm component to issue an audible and visual alarm, and at the same time cut off the power supply to the relevant components through the high voltage protection circuit and the overload protection circuit to ensure the safe operation of the equipment.

[0048] In terms of gas management, the air inlet 20 is connected to the pressure sensor 21 and the air source triplet 22 via pipelines. The pressure sensor 21 monitors the air source pressure in real time and transmits the data to the logic controller 14. The air pressure regulating valve 24 is connected to the gas-liquid booster pump 7 via pipelines. The air pressure regulating valve 24 adjusts the air source pressure according to the instructions of the logic controller 14 to ensure a stable air supply. The multi-position solenoid valve group 23 is connected to the air pressure regulating valve 24 and the air source triplet 22 via pipelines to achieve precise control of the gas flow path. The design of the gas collection tank 25 and the pressure gauge 26 enables the equipment to detect minute leaks and accurately locate the leak point.

[0049] In summary, this invention improves detection sensitivity and automation by optimizing the equipment structure design, enhances adaptability to pipelines of different specifications, and enables rapid location of leak points, thereby significantly improving detection efficiency and accuracy and meeting the demands of modern industry for efficient and intelligent detection equipment.

[0050] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention will be further explained below in conjunction with a specific application scenario.

[0051] In practical applications, this testing equipment is mainly used for airtightness testing in industrial pipeline systems. Taking a chemical plant's pipeline as an example, operators need to perform airtightness testing on a 20-meter-long, 100-millimeter-diameter stainless steel pipe. The specific implementation steps and their principles are as follows:

[0052] First, the operator connects both ends of the pipeline to be tested to the outlet port 3 and return port 4 of the equipment, respectively. Through manual valve 10 adjustment, the liquid medium is drawn from the storage tank 5 by the vortex pump 6, pressurized by the gas-liquid booster pump 7, and then enters the outlet distribution plate 8 through the check valve 27 and the multi-way switching valve 28. During this process, the filter device 18 filters the liquid medium to ensure its cleanliness meets the testing requirements. The coordinated operation of the vortex pump 6 and the gas-liquid booster pump 7 ensures stable pressure of the liquid medium, thereby avoiding testing errors caused by pressure fluctuations.

[0053] Next, the liquid medium is distributed from the outlet diversion plate 8 to the corresponding outlet port 3 and flows into the pipeline to be tested. Due to the flexibility of the diversion component design, operators can select different flow paths using the manual valve 10 to adapt to the testing needs of pipelines of different specifications. During the liquid circulation process, the flow meter 11 monitors the liquid flow rate in real time and transmits the data to the logic controller 14. The logic controller 14 analyzes the flow data through the data processing unit 15 to determine whether there is a leak in the pipeline. If an abnormal flow change is detected, the logic controller 14 will trigger the alarm component to issue an audible and visual alarm, and at the same time cut off the power supply to the relevant components through the high-pressure protection circuit and the overload protection circuit to ensure the safe operation of the equipment.

[0054] Meanwhile, the gas management section introduces a stable gas source through the air inlet 20. The pressure sensor 21 monitors the gas source pressure in real time and transmits the data to the logic controller 14. The multi-position solenoid valve assembly 23 is connected to the gas source triplet 22 and the air pressure regulating valve 24 via pipelines, further enabling precise control of the gas flow path. The pressure sensor 21 and the air pressure regulating valve 24 precisely adjust the gas source pressure according to the instructions of the logic controller 14, ensuring a stable gas supply. The design of the gas collection tank 25 and the pressure gauge 26 allows the device to detect minute leaks and accurately locate the leak point through pressure changes. When a pipeline leaks, gas enters the tank, causing a pressure change. The pressure gauge monitors this in real time and compares it with a preset threshold of the logic controller, triggering leak location. For example, when a minute leak occurs at a certain location in the pipeline, the pressure inside the gas collection tank 25 changes. The pressure gauge 26 can quickly detect this change and feed the data back to the logic controller 14, thereby achieving rapid leak location.

[0055] After testing, the liquid medium returns to the return diversion plate 9 through the return interface 4 and is then reintroduced into the storage tank 5. The manual valve 10 on the return diversion plate 9 can be adjusted as needed to ensure smooth return of the liquid medium. The drain port at the bottom of the storage tank 5 is designed for regular cleaning of accumulated impurities or waste liquid, thereby extending the service life of the equipment.

[0056] Furthermore, the casters at the bottom of the frame 1 and the handles on both sides allow the equipment to be easily moved to the next inspection position. The dust filters embedded in the ventilation openings effectively prevent dust from entering the equipment, ensuring good heat dissipation. The entire inspection process is automated via the control panel 13, reducing manual intervention and significantly improving inspection efficiency and accuracy.

[0057] In summary, this invention improves detection sensitivity and automation by optimizing the equipment structure design, enhances adaptability to pipes of different specifications, and enables rapid location of leak points, thereby significantly improving detection efficiency and accuracy and meeting the needs of modern industry for efficient and intelligent detection equipment.
