Description

Technical Field

[0001] This utility model relates to the field of building pipeline testing equipment, and in particular to a building pipeline pressure testing device with pressure testing function. Background Technology

[0002] In construction engineering, pressure testing must be conducted after pipeline installation to verify the strength and sealing of the pipeline system, ensuring its safety and reliability in subsequent use. Currently, the commonly used pressure testing method mainly relies on a manual pressure testing pump, which constructs a test circuit by connecting hoses, pressure gauges, and various pipe end plugs.

[0003] While this method can meet basic testing requirements, it requires installing hose connectors, fixing plugs, and connecting pressure gauges on-site one by one. Each interface must be manually tightened to prevent leakage, which is not only time-consuming and labor-intensive, but also prone to thread wear or seal failure during frequent disassembly and assembly, affecting test accuracy and safety. In addition, the dispersed layout of multiple components also increases the difficulty of on-site management and the risk of missing parts.

[0004] Therefore, it is necessary to design a pressure testing device for building pipelines with pressure testing capabilities. Utility Model Content

[0005] To overcome the shortcomings of traditional pressure testing methods, such as the need for frequent assembly and disassembly of multiple components, easy leakage and wear at interfaces, cumbersome operation, and easy loss of accessories, which affect the accuracy and safety of testing, this utility model provides a pressure testing device for building pipelines with pressure testing capabilities.

[0006] A pressure testing device for building pipelines includes a support plate, a water storage tank, a sealing cover, a pump body, an outlet check valve, an inlet pipe, a connecting pipe, an inlet check valve, a pressure gauge, and an outlet pipe. The water storage tank is fixedly connected to the top of the support plate, and a sealing cover is threaded onto the top of the water storage tank. The pump body is installed on the top of the support plate, and an inlet pipe connects the water storage tank and the pump body. Two connecting components are provided on the top of the support plate, and a connecting pipe connects the pump body to the connecting components. An inlet check valve is installed on the connecting pipe, and an outlet pipe is connected to the right-end connecting component. An outlet check valve is installed on the outlet pipe, and a pressure gauge is installed on both the inlet check valve and the outlet check valve.

[0007] Optionally, the connecting assembly includes a slide rail, a slider, a connecting seat, and a pipe joint. Two symmetrically distributed slide rails are fixedly connected to the top left and right sides of the support plate. Sliders are slidably connected to the slide rails. A connecting seat is fixedly connected between the two sliders on the same side. The left connecting seat is connected to the connecting pipe, and the right connecting seat is connected to the water outlet pipe. A pipe joint is installed on the side of the two connecting seats that are close to each other.

[0008] Optionally, it also includes a lower clamping block, a screw, a handwheel, an upper clamping block, and a limiting plate. The lower clamping block is fixedly connected to the top of the support plate, the screw is rotatably connected to the top of the lower clamping block, the handwheel is fixedly connected to the top of the screw, the upper clamping block is threaded onto the screw, and multiple limiting plates are fixedly connected to the top of the lower clamping block. The upper clamping block is slidably connected to the limiting plates.

[0009] Optionally, it also includes rubber pads, with rubber pads fixedly connected to the inner walls of both the upper and lower clamping blocks.

[0010] Optionally, it also includes casters, with multiple casters rotatably connected to the bottom of the support plate.

[0011] Optionally, it also includes a push rod, which is fixedly connected to the top of the support plate.

[0012] Beneficial effects: 1. By integrating the water tank, water pump, pressure gauge, connecting components, etc. into one unit, the on-site assembly of disassembled parts is reduced, the operation process is simplified, the risk of loss of parts is reduced, and the problems of frequent disassembly and assembly of multiple parts, easy leakage and wear of interfaces, cumbersome operation, and easy loss of parts in traditional pressure testing methods are solved, which affect the accuracy and safety of testing.

[0013] 2. This utility model adopts a detachable structure of threaded and flanged pipe joints. When replacing, only the fixing bolts between the pipe joint and the connecting seat need to be removed, which can quickly switch to adapt to pipes of different diameters, making it highly versatile.

[0014] 3. This utility model is equipped with a lower clamping block, a screw, a handwheel, an upper clamping block, and a rubber pad. The rotation of the handwheel drives the screw to rotate, thereby causing the upper clamping block to gradually approach and clamp the pipe to be tested with the lower clamping block. The rubber anti-slip pad can fill the small unevenness of the outer wall of the pipe through elastic deformation, which not only improves the clamping stability, but also prevents the metal clamping block from scratching the surface of the pipe.

[0021] Example: A pressure testing device for building pipelines with pressure testing capabilities, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a support plate 1, casters 2, a push rod 3, a water tank 4, a sealing cover 5, a pump body 6, an outlet check valve 7, an inlet pipe 8, a connecting pipe 13, an inlet check valve 14, a pressure gauge 15, and an outlet pipe 16. Two casters 2, symmetrically distributed, are rotatably connected to the front and rear sides of the bottom of the support plate 1. A push rod 3 is welded to the top right end of the support plate 1. A water tank 4 is welded to the top of the support plate 1, and a sealing cover 5 is threaded onto the top of the water tank 4, creating a sealed space. To prevent water leakage or the entry of external impurities during subsequent pressurization, a pump body 6 is installed on the top of the support plate 1. A water inlet pipe 8 is connected between the water storage tank 4 and the pump body 6. Two connecting components are provided on the top of the support plate 1. A connecting pipe 13 is connected between the pump body 6 and the connecting components. A water inlet check valve 14 is installed on the connecting pipe 13. A water outlet pipe 16 is connected to the right end connecting component. A water outlet check valve 7 is installed on the water outlet pipe 16. Pressure gauges 15 are installed on both the water inlet check valve 14 and the water outlet check valve 7.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the connecting assembly includes a slide rail 9, a slider 10, a connecting seat 11, and a pipe joint 12. Two slide rails 9 are welded to the top left and right sides of the support plate 1, which are symmetrically distributed front and back. Sliders 10 are slidably connected to the slide rails 9 through the slide grooves. A connecting seat 11 is welded between the two sliders 10 on the same side. The left connecting seat 11 is connected to the connecting pipe 13, and the right connecting seat 11 is connected to the water outlet pipe 16. The pipe joint 12 is detachably installed on the side of the two connecting seats 11 that is close to each other by bolts.

[0023] like Figure 1 and Figure 5As shown, it also includes a lower clamping block 17, a screw 18, a handwheel 19, an upper clamping block 20, a limiting plate 21, and a rubber pad 22. The lower clamping block 17 is welded to the top of the support plate 1. The screw 18 is rotatably connected to the top of the lower clamping block 17. The handwheel 19 is welded to the top of the screw 18. The upper clamping block 20 is threaded onto the screw 18. Two limiting plates 21 are welded to the top of the lower clamping block 17. The upper clamping block 20 is slidably connected to the limiting plate 21. Rubber pads 22 are adhered to the inner walls of the upper clamping block 20 and the lower clamping block 17. On the one hand, this enhances the friction between the pipe and the lower clamping block 17 and the upper clamping block 20, preventing axial displacement of the pipe during testing. On the other hand, the elastic deformation of the rubber fills the small unevenness of the outer wall of the pipe, further improving the clamping and sealing performance, while avoiding direct contact between the metal clamping block and the pipe, which could cause scratches on the outer wall.

[0024] When pressure testing of a pipeline is required, the operator first uses the push rod 3 to move the device to the construction site of the building pipeline to be tested, relying on the casters 2. After reaching the appropriate position, the casters 2 are locked, then the sealing cover 5 is rotated to open the water tank 4. Sufficient test water is injected into the water tank 4, and the sealing cover 5 is tightened. Next, the connecting components on the left and right sides are adjusted according to the length of the pipeline to be tested. When adjustment is needed, the operator pushes the connecting seat 11 horizontally along the slide rail 9 until the distance between the two connecting seats 11 matches the length of the pipeline to be tested and stops sliding. Then, a pipe fitting 12 that is suitable for the specifications of the building pipeline to be tested is selected, and the pipeline to be tested can be connected. The building pipe is placed in the arc-shaped groove of the lower clamping block 17. The operator can then turn the handwheel 19. The rotation of the handwheel 19 drives the screw 18 to rotate, thereby causing the upper clamping block 20 to slide down along the limiting plate 21 until the arc-shaped inner wall of the upper clamping block 20 is in contact with the outer wall of the pipe. Continue to fine-tune the handwheel 19 so that the upper clamping block 20 and the lower clamping block 17 clamp the pipe together. At this time, the rubber pad 22 will be tightly attached to the surface of the pipe. Then, the pipe to be tested is vented. After the venting is completed, the two ends of the pipe to be tested are aligned with the pipe joints 12 on the left and right connecting seats 11 respectively. Push the connecting seats 11 to fine-tune the position so that the two ends of the pipe are sealed to the flange of the pipe joint 12 by bolts.

[0025] Pump body 6 can be started and inlet check valve 14 opened. Pump body 6 generates negative pressure, drawing test water from water storage tank 4 into it through inlet pipe 8. After pressurizing the water, pump body 6 delivers the high-pressure water through connecting pipe 13 to pipe joint 12 of left end connecting seat 11, entering the pipe to be tested and gradually filling the cavity inside the pipe. As pump body 6 continues to pressurize, water accumulates in the pipe, and the pressure gradually increases. Pressure gauge 15 on inlet check valve 14 detects the pressure from pump body 6 outlet to pipe inlet, reflecting the pressurized output pressure of pump body 6. Pressure gauge 15 on outlet check valve 7 detects the pressure from pipe outlet to outlet pipe 16, reflecting the actual pressure inside the pipe. When the pressure gauge 15 reading at outlet check valve 7 reaches the preset test value... When the pressure is set according to the building pipeline design standards, such as the test pressure of water supply and drainage pipelines, which is usually 1.5 times the working pressure, the pump body 6 is turned off and the pressure holding stage is entered (the pressure holding time is usually 30 minutes to 1 hour). During the pressure holding process, the operator continuously observes the changes in the readings of the two pressure gauges 15. If the readings of the two pressure gauges 15 remain stable without significant drop, it indicates that the pipeline under test has no leakage and the pressure resistance performance meets the standards. If the reading of pressure gauge 15 at the outlet check valve 7 continues to drop, while the reading of pressure gauge 15 at the inlet check valve 14 remains stable, it indicates that there is a leak in the pipeline under test. If the readings of the two pressure gauges 15 drop at the same time, it is necessary to check whether the sealing cover 5 of the water storage tank 4 is loose, and whether there is a leak in the inlet pipe 8 or the connecting pipe 13. After eliminating the problem of the device itself, the test is repeated.

[0026] After the test is completed, the operator first opens the outlet check valve 7. The high-pressure water in the test pipeline is discharged through the outlet pipe 16 and the outlet check valve 7. At this time, the readings of the two pressure gauges 15 gradually drop to atmospheric pressure until the pointers return to zero, confirming that the pressure in the pipeline has been completely released. Then, the handwheel 19 is turned in the opposite direction to make the upper clamp 20 slide upward along the limit plate 21 and separate from the surface of the pipeline to be tested, thereby releasing the clamping and fixing of the pipeline to be tested. Then, the bolts at both ends are removed to separate the pipe joint 12 from the two ends of the pipeline. The connecting seat 11 is pushed to slide along the slide rail 9 to remove the pipeline to be tested. If other pipelines need to be tested later, the above operation can be repeated. When the test is over, the residual water at the pipe joint 12 is cleaned and the device is pushed to the storage position, thus completing the use of this device.
