Description

Technical Field

[0001] This utility model relates to the field of hydraulic testing equipment for oil and gas extraction pipe components, and specifically to a modular combined hydraulic testing equipment. Background Technology

[0002] Hydraulic testing equipment is crucial for inspecting pipe components in oil and gas extraction equipment. Hydraulic testing can detect processing defects in pipe workpieces and determine if they meet operating pressure requirements. Existing hydraulic testing equipment for pipe workpieces relies on the factory floor, requiring the excavation of pits at fixed locations. Therefore, this existing pit-type hydraulic testing equipment suffers from long installation cycles, relocation difficulties, and a large footprint. Furthermore, the fixed operating location limits the length range of pipe components that can be tested, making it difficult to adapt to the needs of multi-scenario testing.

[0003] In addition, existing hydraulic testing equipment lacks protection for pipe components at the testing station, has insufficient safety protection during equipment pressure testing, and relies on heavy infrastructure, resulting in high operation and maintenance costs. It also cannot achieve rapid deployment and dynamic adjustment, which seriously restricts the flexibility and economy of high-pressure testing operations.

[0004] To address the problems existing in the prior art, this utility model designs a hydraulic testing device for pipe components to overcome the aforementioned deficiencies. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a hydraulic testing device for tubular components. In the testing area of ​​the tubular components, a modular protective structure is set up to avoid a lack of protection during hydraulic testing and pressurization. The modular protective structure can be adjusted and combined according to the length of the tubular components to accommodate tubular components of different lengths.

[0006] This utility model provides a hydraulic testing device for pipe components, characterized in that it includes:

[0007] A valve assembly module is located at the rear of the hydraulic testing equipment and is connected to pipe components via connectors.

[0008] A pump module that integrates multiple hydraulic pumps into a single module and is connected to the valve module. The pump module is located to the side and front of the valve module and includes a high-pressure water injection pump and a low-pressure water injection pump.

[0009] The safety isolation room consists of multiple detachable isolation panels and multiple top cover panels. Pipe components are placed longitudinally inside the safety isolation room. The multiple top cover panels are hinged to one side of the perimeter formed by the isolation panels. A stepped overlapping plate is provided at the connection between two adjacent isolation panels.

[0010] The control center is electrically connected to the valve group module and the pump group module, and controls the valve group module and the pump group module to perform hydraulic tests on the pipe components; the hydraulic testing equipment is mounted on the platform.

[0011] Furthermore, a protective plate is provided between the valve assembly module and the pipe component. The connecting pipe of the valve assembly module passes through a pre-set opening in the protective plate and is connected to one end of the connector. The other end of the connector is connected to the pipe component through a flange.

[0012] Furthermore, the valve group module integrates a pump-end unloading valve, a check valve, and a container unloading valve. The valve group module can connect to multiple sets of pipe components for simultaneous testing, and multiple sets of pipe components can be controlled and tested individually. The pump-end unloading valve is connected to the check valve pipeline, which can prevent the check valve pressure from being too high during high-pressure testing.

[0013] Furthermore, hydraulic cylinders are evenly spaced inside the safety isolation chamber along the longitudinal direction of the tubular components. The bottom of the hydraulic cylinders is fixed to the platform, and the hydraulic rod at the top of the hydraulic cylinder is hinged to the bottom of the top cover panel. The extension and retraction of the hydraulic rod drives the opening and closing of the top cover panel.

[0014] Furthermore, one edge of the top cover panel is hinged to the isolation panel, and the other edge is provided with a locking lug. The top cover panel rotates around the hinged connection, and when the top cover panel rotates to a horizontal position, the top cover panel closes the space above the space enclosed by the multiple isolation panels.

[0015] Furthermore, the isolation enclosure is equipped with a locking cylinder at the locking lug of the top cover enclosure. When the top cover enclosure is closed, the telescopic end of the locking cylinder extends and engages with the locking hole of the locking lug to lock it. When the top cover enclosure needs to be opened, the telescopic end of the locking cylinder retracts first to release the lock.

[0016] Furthermore, fastening plates are provided on the inner and outer walls of the isolation enclosure. One end of the fastening plate is integrally connected to the inner and outer walls of the isolation enclosure, and the other end is fastened to the platform.

[0017] Furthermore, a sensor is also provided at the locking cylinder. The sensor can sense the opening and closing state of the top cover panel and send the sensing signal to the locking cylinder, which controls the extension and retraction of the telescopic end.

[0018] Furthermore, the overlapping plate and the isolation enclosure are integrated, and multiple isolation enclosures are fastened together by overlapping plate screws.

[0019] Furthermore, a leakage water tank is provided on the platform inside the safety isolation room.

[0020] The advantages of this utility model are:

[0021] 1. A safety isolation chamber is formed by multiple detachable and connected isolation panels and corresponding top cover panels. The length of the safety isolation chamber can be adjusted according to the length of the test pipe components, so that the hydraulic testing equipment can adapt to multiple testing scenarios. When the length of the isolation chamber is excessive, it can be flexibly disassembled to reduce site occupation and improve the space utilization rate of the factory workshop. The top cover panels can prevent pipe components from being impacted during hydraulic high-pressure testing and improve equipment safety.

[0022] 2. It integrates pump and valve modules, making the hoisting, transportation, and installation of the equipment quick and convenient, and shortening the deployment cycle.

[0023] 3. Connect the pump end unloading valve to the check valve pipeline. Before the high-pressure pressure test of the pipeline components, open the pump end unloading valve to protect the check valve and prevent it from being damaged by high pressure. Attached Figure Description

[0034] As described in the background section, existing hydraulic testing equipment for tubular workpieces has a fixed operating location, long installation period, difficulty in relocation, and occupies a large factory area. Furthermore, the length range of the tubular components that can be tested is limited, making it difficult to meet the needs of multi-scenario testing, and there is a lack of effective safety protection for the equipment.

[0035] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0036] like Figure 1 A hydraulic testing device for pipe components includes an integrated pump module 4 and a valve module 1. The valve module 1 is located at the rear of the overall device, and the pump module 4 is located at the front side of the valve module 1. The valve module 1 and the pump module 4 are connected via pipelines. A control center 8 is electrically connected to the pump module 4 and the valve module 1.

[0037] Pump module 4 integrates the hydraulic pump and related accessories into a single module, facilitating hoisting, transportation, and rapid deployment. It mainly includes a high-pressure water injection pump and a low-pressure water injection pump. The low-pressure water injection pump is responsible for the rapid filling of the medium within the pipe component 3 during the initial testing phase and for increasing the pressure during the low-pressure phase, with an injection rate of up to 20 cubic meters per hour. The high-pressure water injection pump is used to increase the testing pressure of the pipe component 3 during the high-pressure phase, reaching a test pressure of up to 400 MPa, meeting the testing requirements of the pipe component 3. Pump module 4 integrates both low-pressure and high-pressure water injection pumps, improving testing efficiency.

[0038] Valve module 1 integrates components such as check valve, pump end unloading valve, container unloading valve, and pressure detection unit into a single module, which can support multi-line water injection and pressure boosting control, improve pressure testing efficiency, and each line can be independently controlled to open and close, and can be remotely controlled through control center 8.

[0039] The control center 8 integrates the control system of the hydraulic testing equipment, as well as other auxiliary facilities. The test control system mainly includes an industrial computer, an electrical control console, a PLC program logic controller, a monitoring system, etc., which can automatically start up, automatically detect, automatically maintain pressure, automatically depressurize, and read and save test data.

[0040] Pump module 4 is connected to valve module 1. Valve module 1 is connected to pipe component 3 via connector 2. Control center 8 performs hydraulic testing on pipe component 3 by controlling pump module 4 and valve module 1.

[0041] The hydraulic testing equipment also includes a safety isolation chamber, which is a space enclosed by multiple detachable isolation panels 5 and multiple top cover panels 6. Pipe components 3 are placed longitudinally within the safety isolation chamber for hydraulic testing. The top cover panels 6 are hinged to one side of the enclosure of the isolation panels 5, sealing off the upper space of the chamber to prevent damage to the pipe components 3 during hydraulic testing, thus ensuring the safety of the equipment and operators. Adjacent isolation panels 5 are connected using stepped lap plates 7 with screws. The lap plates 7 can be an integral extension of an isolation panel 5, connecting to the other end of an adjacent isolation panel 5, or they can be independent connecting structures linking two isolation panels. The hydraulic testing equipment is mounted on a platform 9. A leakage trough is also provided on the platform 9 within the safety isolation chamber, along the longitudinal direction of the pipe components 3, for timely drainage.

[0042] like Figure 1 and Figure 2As shown, a protective plate 10 is provided between the valve assembly module 1 and the pipe component 3. The connecting pipe of the valve assembly module 1 passes through a preset opening on the protective plate 10 and is connected to one end of the connector 2. The other end of the connector 2 is connected to the pipe component 3 to be tested through a flange. Hydraulic cylinders 11 are evenly spaced inside the safety isolation chamber along the longitudinal direction of the pipe component 3. The bottom of the hydraulic cylinder 11 is fixed on the platform 9. The hydraulic rod 12 at the telescopic end of the hydraulic cylinder 11 is hinged to the bottom of the top cover plate 6. The telescopic movement of the hydraulic rod 12 drives the top cover plate 6 to open and close. When the top cover plate 6 rotates to the horizontal position, the top cover plate 6 closes the space above the space enclosed by multiple isolation plates 5.

[0043] like Figure 1 and Figure 3 As shown, one side edge of the top cover panel 6 is hinged to the vertical isolation panel 5. The top cover panel 6 can rotate around the hinge point through the telescopic movement of the hydraulic rod 12. The other side edge of the top cover panel 6 is provided with a locking lug 13, which has a locking hole. The isolation panel 5 is provided with a locking cylinder 14 corresponding to the locking lug 13 of the top cover panel 6. When the top cover panel 6 rotates to a horizontal position to close the safety isolation chamber, that is, when the top cover panel 6 is closed, the telescopic end of the locking cylinder 14 extends and inserts into the locking hole of the locking lug 13, thereby locking the top cover panel 6 and closing the safety isolation chamber. The pipe component 3 begins testing. When the test is completed and the top cover panel 6 needs to be opened, the telescopic end of the locking cylinder 14 retracts and releases the lock. The number of locking cylinders 14 is consistent with the number of locking lugs 13. A sensor 16 is also provided at the location of the locking cylinder 14. The sensor 16 is used to sense the opening and closing state of the top cover plate 6 and sends a sensing signal to the locking cylinder 14. The locking cylinder 14 controls the extension end to extend and retract from the locking hole. The extension direction of the extension end of the locking cylinder 14 is perpendicular to the plane containing the rotation direction of the top cover plate 6. In addition, fastening plates 15 are provided on the inner and outer walls of the isolation plate 5. One end of the fastening plate 15 is integrally connected to the inner and outer walls of the isolation plate 5, and the other end is fixed to the platform 9 by screws. The fastening plate 15 can effectively enhance the connection strength and stability of the isolation plate 5.

[0044] like Figure 4 As shown, the specific process of hydraulic testing of a hydraulic testing device for pipe components according to this utility model is as follows:

[0045] S1. After hoisting the pipe component to be tested into the test station of the safety isolation chamber, install the detection sensor on the pipe component, turn on the control center, start the hydraulic cylinder to drive the hydraulic rod to close the top cover plate. After the sensor detects that the top cover plate is closed, it sends a signal to the locking cylinder. The locking cylinder inserts the telescopic end into the locking hole of the locking lug on the side edge of the top cover plate, sealing the space above the safety isolation chamber formed by the isolation plate.

[0046] S2, Start the hydraulic testing equipment. The pump module and valve module work together to start the low-pressure water injection pump. After the venting is completed, close the container unloading valve. After the low pressure is reached, close the low-pressure water injection pump and also close the pump end unloading valve to prepare for subsequent high-pressure water injection.

[0047] S3, start the high-pressure water injection pump, and continue to pressurize the pipe components until the test pressure requirement is reached. Then, turn off the high-pressure water injection pump and open the pump end unloading valve to maintain the pressure on the pipe components and check the pressure. After the pressure holding time is over, open the container unloading valve to end the pressure holding process.

[0048] S4, the hydraulic testing equipment is depressurized, the test record is saved and printed, the locking cylinder extension end exits the locking hole of the locking lug, the hydraulic rod drives the top cover panel to open, and the hydraulic test process ends.

[0049] In the hydraulic testing equipment for pipe components of this utility model, a check valve and a pump-end unloading valve are connected in series. One end of the check valve is connected to the pump-end unloading valve, and the other end is connected to connector 2. One end of the pump-end unloading valve is connected to the check valve, and the other end is connected to pump module 4. This series pipeline allows the high-pressure to be released promptly after high-pressure pressurization via the pump-end unloading valve, protecting the check valve from high-pressure damage, improving the pressure-holding performance of the equipment, and extending its service life. In this utility model, as... Figure 1 As shown, the longitudinal arrangement direction along the tubular component 3 is the front-to-back direction.

[0050] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
