[0026] In this embodiment, the air is compressed by continuously moving the pressure rod 16. At this time, the hydraulic top 21 transmits the compressed air to the inside of the water pipeline 1 through the air inlet pipe 19. By continuously pumping air, the air pressure inside the water pipeline 1 is increased to facilitate subsequent testing. Example 2
[0027] like Figure 3~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a first fixing pin 2 is embedded at the top of the water delivery pipe 1, a rotating block 3 is rotatably connected to the outer side of the top of the first fixing pin 2, a connecting rod 4 is fixed to the top of the rotating block 3, and a handle 6 is rotatably connected to the outer side of the connecting rod 4, a test head 5 is fixedly connected to the top of the connecting rod 4, a base 7 is fixedly connected to the top of the test head 5, a test gauge 8 is fixedly connected to the top of the base 7, and the internal air pressure can be more accurately seen according to the test gauge 8 inside the water delivery pipe 1, a nut 9 is fixedly connected to the top of the collar 12, a notch is provided inside the nut 9, and a detection device is added to the top of the nut 9 to facilitate installation, a collar 12 is sleeved on the outer side of the water delivery pipe 1, and the outer side of the collar 12 A rotating pin 11 is fixedly connected, and the outer side of the rotating pin 11 passes through the inside of the collar 12. By adding the collar 12 on the outside of the water pipe 1, it is convenient to stop the water flow. A rotating ring 10 is welded on the outer side of the rotating pin 11, and the rotating ring 10 rotates inside the water pipe 1. By placing the rotating ring 10 inside the rotating pin 11, the rotating pin 11 is moved to rotate inside the water pipe 1, thereby blocking the water flow. A third fixed pin 20 is sleeved on the outer side of the air inlet pipe 19, and the third fixed pin 20 is embedded in the inside of the water pipe 1. By sleeved one end of the air inlet pipe 19 on the inside of the third fixed pin 20, and the third fixed pin 20 is embedded in the inside of the water pipe 1, it is convenient to pressurize the water pipe 1 and test the internal pressure of the water pipe 1.
[0028] In this embodiment, a test gauge 8 is fixedly connected to the top of the base 7, and the internal air pressure conditions can be more accurately seen based on the test gauge 8 inside the water pipe 1. By adding a ring 12 on the outside of the water pipe 1, it is convenient to stop the water flow.
[0029] Working principle:
[0030] First, the staff will place water inside the water pipe 1, and insert the air inlet pipe 19 into the third fixing pin 20 at the top of the water pipe 1, and insert the other end of the air inlet pipe 19 into the second fixing pin 18. After the air inlet pipe 19 is connected to the water pipe 1, move the pressure rod 16 downward. At this time, the pressure rod 16 squeezes the pressing block 17 to slide downward, and cooperates with the extension block 22 on the outside of the hydraulic top 21. The rotating arm 15 supports it, and the air is compressed by continuously moving the pressure rod 16. At this time, the hydraulic top 21 transmits the compressed air to the inside of the water pipe 1 through the air inlet pipe 19. By continuously pumping air, the air pressure inside the water pipe 1 is increased, and according to the test table 8 inside the water pipe 1, the internal air pressure situation can be seen more accurately, and no more water source is required for pressure testing during the pressure test.
[0031] Furthermore, when it is necessary to repair the interior of the water pipeline 1 and place the test meter 8, there is no need to stop the water supply to the interior of the water pipeline 1. It is only necessary to rotate the swivel 10. At this time, the swivel 10 blocks and intercepts the water inside the water pipeline 1 to prevent the water from the outside from entering the interior of the water pipeline 1. The construction can be carried out without stopping the water supply, thereby improving the transmission efficiency.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
