Description

Technical Field

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

[0002] Pipeline leak testing is a method used to check for leaks in pipeline systems. It involves filling the system with gas or liquid at a certain pressure and then observing whether the pressure drops. If the pressure drop exceeds a specified range, a leak may exist, facilitating an assessment of the pipeline system's quality.

[0003] When testing existing pipelines, first press the power button to start the system circuit and test whether the solenoid valve and printer are working properly. At this time, the solenoid valve is closed. After ensuring that all components are working properly, open the manual ball valve and connect both ends of the pipe to be tested to the quick-release connectors. When the pressure holding process and the final pressure change are within the normal range, it is determined that the pipe to be tested has no leakage.

[0004] The existing method for leak detection of pipe fittings requires connecting both ends of the fitting to quick-release connectors. Although this is simple and easy, when connecting the quick-release connectors, the operator needs to hold the fitting to connect the first quick-release connector and then hold it to install the other fitting. This is to reduce the risk of the fitting falling off the quick-release connector. The operation is cumbersome and inconvenient for operators. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that workers need to hold the pipe fittings by hand to connect the first quick-release connector, and after connecting, they still need to hold them by hand to install the other pipe fittings, which is a cumbersome operation process. This utility model provides a pipe leakage testing device.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A pipeline leak testing device includes a working box with several support legs installed at the bottom. An alarm is installed on the outside of the working box. A water pipe is fixedly connected to the outside of the working box. A solenoid valve and a manual ball valve are installed on the outside of the water pipe. A second water pipe is installed on the outside of the first water pipe, and the first and second water pipes are connected. Quick-release connectors are installed at the outlet ends of both the first and second water pipes. A pressure gauge is installed on the outside of the second water pipe. An electrical control box is fixedly connected to the outside of the working box. A printer is installed on the outside of the working box. A positioning mechanism is installed on the outside of the support legs.

[0008] By adopting the above technical solution, first disconnect the circuit and close the manual ball valve. Press the power on button to start the system circuit. Open the manual ball valve and connect both ends of the pipe fitting to the quick-release connectors. Press the test button, and the system will run normally according to the set pressure holding value and pressure holding time. When the pressure holding process and the final pressure change are within the normal range, it is determined that there is no leakage in the pipe fitting under test. The printer will output a test qualified report and control the alarm to remind you that the test is completed by light. The positioning mechanism can reduce the inconvenience when connecting the pipe fitting to the quick-release connector.

[0009] Furthermore, the positioning mechanism includes a connecting frame fixedly connected to the outside of the support leg, a connecting plate slidably connected between the two connecting frames, a horizontal plate fixedly connected to the outside of the connecting plate, a vertical plate fixedly connected to the top of the horizontal plate, a threaded rod threadedly connected to the outside of the vertical plate, one end of the threaded rod passing through the vertical plate and rotatably connected to a clamping block, and an abutment block fixedly connected to the top of the connecting plate.

[0010] By adopting the above technical solution, the pipe fitting is placed in the placement groove at the top of the connecting plate. Then, the threaded rod is rotated and connected to the vertical plate by threads, causing the threaded rod to move. The movement of the threaded rod drives the clamping block to move, and the movement of the clamping block will abut against the pipe fitting, so that the pipe fitting is fixed in the placement groove of the connecting plate.

[0011] Furthermore, the sides of the clamping block and the contact block that are close to each other are both set as arc surfaces, and a buffer pad is fixedly connected to the sides of the clamping block and the contact block that are close to each other.

[0012] By adopting the above technical solution, and using rubber as the buffer pad, a buffering effect can be achieved between the clamping block and the pipe fitting.

[0013] Furthermore, a guide rod is fixedly connected to the outside of the clamping block, one end of the guide rod passes through the vertical plate, and the guide rod is slidably connected to the vertical plate.

[0014] By adopting the above technical solution, the guide rod provides guidance for the clamping block, enabling the clamping block to maintain the correct movement trajectory when moving.

[0015] Furthermore, connecting blocks are symmetrically fixedly connected to the outer side of the connecting plate, sliding holes are provided on the outer side of the connecting frame, the connecting blocks are slidably connected to the sliding holes, a fixing plate is fixedly connected to the outer side of the connecting blocks, a locking block is slidably connected to the outer side of the fixing plate, and a plurality of locking blocks are symmetrically provided on the outer side of the connecting frame, the locking blocks being slidably connected to the locking grooves.

[0016] By adopting the above technical solution, the connecting plate is moved between the two connecting frames. The movement of the connecting plate causes the connecting block to move, and the movement of the connecting plate causes the fixing plate to move. When the connecting plate moves to a suitable height, the worker inserts the locking block into the locking groove, thereby fixing the connecting plate at the appropriate height.

[0017] Furthermore, an auxiliary rod is fixedly connected to the inner side of the connecting frame, one end of the auxiliary rod passes through the fixing plate, and the auxiliary rod is slidably connected to the fixing rod.

[0018] By adopting the above technical solution, the auxiliary rod provides an additional support point for the connecting plate, so that the connecting plate can move smoothly.

[0019] In summary, this utility model has at least one of the following beneficial effects:

[0020] 1. In this utility model, when connecting pipe fittings, rotating the threaded rod causes the clamping block to move and abut against the pipe fittings, so that the workers no longer need to hold the pipe fittings and quick-release connectors by hand as before, which reduces the risk of inconvenience in the connection process, improves the convenience of the connection process, and thus improves the operation efficiency.

[0021] 2. In this utility model, when the connecting plate is moved to a suitable height, the operator inserts the locking block into the locking groove. The adjustable height of the connecting plate can flexibly adapt to various working scenarios and is suitable for operators of different heights, thereby reducing operator fatigue and improving work efficiency.

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] This utility model discloses a pipeline leakage testing device.

[0031] Refer to 1 and Figure 2 A pipeline leakage testing device includes a working box 1, with several support legs 10 installed at the bottom of the working box 1. An alarm 2 is installed on the outside of the working box 1. A water pipe 3 is fixedly connected to the outside of the working box 1. A solenoid valve is installed on the outside of the water pipe 3. A manual ball valve 4 is installed on the outside of the water pipe 3. A second water pipe 24 is installed on the outside of the water pipe 3. The water pipe 3 and the second water pipe 24 are connected. Quick-release connectors 7 are installed at the outlet ends of both the second water pipe 24 and the first water pipe 3. A pressure gauge 6 is installed on the outside of the second water pipe 24. An electrical control box 8 is fixedly connected to the outside of the working box 1. A printer 9 is installed on the outside of the working box 1. A positioning mechanism is installed on the outside of the support legs 10.

[0032] When testing the pipeline, first disconnect the power and close the manual ball valve 4. Then connect the working box 1 to the fluid source and press the power on button. The system circuit will start working. Open the manual ball valve 4 and connect both ends of the pipe fitting to the quick-release connector 7 respectively. Press the test button, and the system will run normally according to the set pressure holding value and pressure holding time. When the pressure holding process and the final pressure change are within the normal range, it is determined that the pipe fitting under test has no leakage. The printer 9 outputs a test qualified report and controls the alarm 2 to remind you of the test completion through light. When the pressure holding process and the final pressure drop exceed the normal range, it is determined that the pipe fitting under test has leakage. The system closes the solenoid valve to cut off the pipeline to reduce continuous leakage. The printer 9 outputs a test unqualified report and controls the alarm 2 to remind you of the pipe fitting leakage through sound and light. The positioning mechanism can reduce the inconvenience when connecting the pipe fitting to the quick-release connector 7.

[0033] Reference Figure 3 and Figure 4The positioning mechanism includes a connecting frame 11 fixedly connected to the outside of the support leg 10, a connecting plate 12 slidably connected between the two connecting frames 11, a horizontal plate 13 fixedly connected to the outside of the connecting plate 12, a vertical plate 14 fixedly connected to the top of the horizontal plate 13, a threaded rod 15 threadedly connected to the outside of the vertical plate 14, one end of the threaded rod 15 passing through the vertical plate 14 and rotatably connected to a clamping block 16, and an abutment block fixedly connected to the top of the connecting plate 12.

[0034] The clamping block 16 and the contact block are both made of arc surface on the side that are close to each other, and a buffer pad 17 is fixedly connected to the side that is close to each other on the clamping block 16 and the contact block.

[0035] In addition, a guide rod 18 is fixedly connected to the outside of the clamping block 16. One end of the guide rod 18 passes through the vertical plate 14, and the guide rod 18 is slidably connected to the vertical plate 14.

[0036] When connecting the pipe fitting, first place the pipe fitting in the placement slot at the top of the connecting plate 12, then rotate the threaded rod 15 to rotate. The threaded rod 15 is threadedly connected to the vertical plate 14, causing the threaded rod 15 to move. The movement of the threaded rod 15 drives the clamping block 16 to move. The movement of the clamping block 16 will abut against the pipe fitting, so that the pipe fitting is fixed in the placement slot of the connecting plate 12. This eliminates the need for workers to hold the pipe fitting and quick-release connector 7 by hand as before.

[0037] When the contact block comes into contact with the pipe fitting, the rubber buffer pad 17 can act as a buffer between the clamping block 16 and the pipe fitting, reducing the risk of the pipe fitting surface being scratched or worn.

[0038] When the clamping block 16 moves, the guide rod 18 provides guidance to the clamping block 16, so that the clamping block 16 can maintain the correct movement trajectory when moving.

[0039] Reference Figure 3 and Figure 5 The outer side of the connecting plate 12 is symmetrically fixedly connected with connecting blocks 19. The outer side of the connecting frame 11 is provided with sliding holes. The connecting blocks 19 are slidably connected to the sliding holes. The outer side of the connecting blocks 19 is fixedly connected with a fixing plate 20. The outer side of the fixing plate 20 is slidably connected with a locking block 22. The outer side of the connecting frame 11 is provided with a plurality of locking blocks 22. The locking blocks 22 are slidably connected to the locking grooves 21.

[0040] An auxiliary rod 23 is fixedly connected to the inner side of the connecting frame 11. One end of the auxiliary rod 23 passes through the fixing plate 20, and the auxiliary rod 23 is slidably connected to the fixing rod.

[0041] When adjusting the height of the connecting plate 12, the connecting plate 12 is first moved between the two connecting frames 11. The movement of the connecting plate 12 causes the connecting block 19 to move, and the movement of the connecting plate 12 causes the fixing plate 20 to move. When the connecting plate 12 moves to the appropriate height, the operator inserts the locking block 22 into the locking groove 21, thereby fixing the connecting plate 12 at the appropriate height. The adjustable height of the connecting plate 12 can flexibly adapt to various working scenarios and is suitable for operators of different heights, thereby reducing operator fatigue and improving work efficiency.

[0042] When the connecting plate 12 moves, the auxiliary rod 23 provides an additional support point for the connecting plate 12, so that the connecting plate 12 can move smoothly.

[0043] Working principle: First, disconnect the power to the circuit and close the manual ball valve 4. Then, connect the working box 1 to the fluid source and press the power-on button. The system circuit starts working. Open the manual ball valve 4 and connect both ends of the pipe fitting to the quick-release connector 7 respectively. Press the test button. The system will run normally according to the set pressure holding value and pressure holding time. When the pressure holding process and the final pressure change are within the normal range, it is determined that there is no leakage in the pipe fitting under test. The printer 9 outputs a test qualified report and controls the alarm 2 to remind you that the test is completed by light. When connecting the pipe fitting, first place the pipe fitting in the placement slot at the top of the connecting plate 12. Then rotate the threaded rod 15. The threaded rod 15 is threadedly connected to the vertical plate 14, which makes the threaded rod 15 move. The movement of the threaded rod 15 drives the clamping block 16 to move. The movement of the clamping block 16 will abut against the pipe fitting, so that the pipe fitting is fixed in the placement slot of the connecting plate 12. This eliminates the need for the staff to hold the pipe fitting and quick-release connector 7 by hand as before.
