[0023] In the prior art, since the pipeline is buried underground, the ground environment is uncertain, production activities such as vehicles on the surface will cause the pipeline to vibrate, and multiple factors such as underground water flow will also cause the pipeline to vibrate. Therefore, the above-mentioned leakage detection of the pipeline through vibration has a large error and poor detection effect. Therefore, the inventor has provided a pipeline leakage detection device to solve the above-mentioned defects after research.

[0024] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figures 1 to 4 The utility model provides a pipeline leakage detection device, including a pipeline body 1 and a control valve 4 equidistantly installed on the pipeline body 1. A plurality of detection tubes 3 are fixedly installed on the pipeline body 1. The hollow cavity of the detection tube 3 is configured to accommodate a cavity 9. A piston 16 is elastically inserted at one end of the cavity 9, and an adjustment plate 7 is adjustably embedded and fixed at the other end of the cavity 9. A pressure indicating rod 12 is detachably installed on the side wall of the piston 16. A through hole 10 is opened at the center of the adjustment plate 7. The pressure indicating rod 12 is slidably inserted in the through hole 10. 0, and is protrudingly arranged on the side wall of the accommodating cavity 9. When the pipeline is inspected, the control valve 4 is closed to keep the water flow in a stable state. The water pressure in the pipeline body 1 squeezes the piston 16 to drive the pressure indicating rod 12 to move synchronously. When the pipeline body 1 leaks, after a certain period of time, as the water leaks, the internal pressure of the pipeline body 1 decreases. By recording the position of the scale groove 18 on the pressure indicating rod 12 at different time periods, it is possible to determine whether the pipeline body 1 is leaking, thereby improving the convenience and accuracy of the pipeline body 1 leakage detection.

[0026] The outer wall of the pipeline body 1 is equidistantly fixed with mounting tubes 6 located between the two control valves 4, and a threaded tube 5 is protruding and fixed on the side wall of the mounting tube 6. A control rod is rotatably inserted in the control valve 4, and a knob 2 fixedly sleeved on the control rod is provided above the control valve 4. The control valve 4 can be easily switched on and off by means of the knob 2. The detection tube 3 is threadedly sleeved on the threaded tube 5, and an anti-slip sleeve 11 is embedded and fixed on the outer wall of the detection tube 3. The detection tube 3 is driven to rotate by the anti-slip sleeve 11, and the detection tube 3 is unscrewed from the threaded tube 5 during the rotation process, so that the detection tube 3 is easy to install and disassemble.

[0027] The adjusting plate 7 is threadedly inserted into the detection tube 3, and the side wall of the adjusting plate 7 is symmetrically provided with gripping grooves 8. A spring 17 is embedded in the center of the accommodating cavity 9, and the two ends of the spring 17 are respectively abutted against the piston 16 and the adjusting plate 7. The pressure indicating rod 12 is embedded in the spring 17, and the outer wall of the pressure indicating rod 12 is equidistantly provided with scale grooves 18. The gripping groove 8 drives the adjusting plate 7 to rotate in the detection tube 3, and the spring 17 is squeezed during the rotation, so that the position and elastic force of the spring 17 are adjusted, which is suitable for leakage detection of internal pressures of different pipeline bodies 1.

[0028] A sealing ring 14 is fixedly sleeved on the piston 16, and the sealing ring 14 is tightly connected to the inner wall of the detection tube 3. A screw hole 15 is opened on the side wall of the piston 16. A screw 13 threadedly inserted in the screw hole 15 is fixed on the pressure indicating rod 12. An anti-slip ring 19 is embedded and fixed in the detection tube 3. The side wall of the piston 16 abuts against the anti-slip ring 19. The pressure indicating rod 12 is rotated to drive the screw 13 to turn the knob 2 in the screw hole 15, thereby disassembling and replacing the pressure indicating rod 12.

[0029] In summary, when testing the pipeline, close the control valve 4 to keep the water flow in a stable state, and the water pressure in the pipeline body 1 squeezes the piston 16 to drive the pressure indicator rod 12 to move synchronously. When the pipeline body 1 leaks, after a certain period of time, as the water leaks, the internal pressure of the pipeline body 1 decreases. By recording the position of the scale groove 18 on the pressure indicator rod 12 in different time periods, it is possible to determine whether the pipeline body 1 is leaking, thereby improving the convenience and accuracy of leakage detection of the pipeline body 1. The above is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
