If multiple products are placed in the same testing device for testing, when one of the products has a problem, the entire testing device needs to be stopped to take out the problematic product for inspection. This will cause changes in the pressure on the remaining products in the same testing device, affecting the test accuracy of the remaining products. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a water pressure detection device to address the deficiencies of the prior art, and to set up multiple parallel pressure tanks.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 3 , the water pressure detection device provided by the utility model, see Figure 1 As shown, it includes an air intake pipeline 1, an air intake valve 2, a pressure relief valve 3, multiple branch valves 4 and multiple pressure tanks 5. The air intake valve 2 is arranged at one end of the air intake pipeline 1, and the pressure relief valve 3 is arranged at the other end, wherein the air intake valve 2 is connected to the gas source to provide pressure for the device. A sealing cover 6 is arranged at the tank mouth of each pressure tank 5, and each pressure tank 5 is connected to the air intake pipeline 1 through a branch valve 4. By operating the branch valve 4 on each branch, it is possible to control whether the pressure tank 5 is connected to the air intake pipeline 1, which is more flexible to use and has a wide range of applications.

[0028] It also includes a drainage pipeline 7, a drainage valve 8 and multiple branch valves 9. One end of the drainage pipeline 7 is sealed, and the other end is provided with a drainage valve 8. The bottom of each pressure tank 5 is connected to the drainage pipeline 7 through a branch valve 9. By opening the drainage valve 8, the water in the pressure tank 5 can be released directly. A pressure gauge 15 is provided on the drainage pipeline 7 to facilitate observation of the water pressure inside the water pressure detection device.

[0029] It also includes a pressure regulating valve 10, which is connected in series to the intake pipe 1 between the intake valve 2 and the first branch valve 4. The pressure regulating valve 10 can be used to connect an uninterrupted air source to the intake valve 2, and the intake valve 2 remains in a normally open state. After the pressure regulating valve 10 sets the pressure, the pressure inside the intake pipe 1 will remain constant. Even if a leak occurs during the test, the pressure will not drop. There is no need to monitor the pipeline pressure all the time during the test, which improves convenience.

[0030] It also includes a movable bracket 11, on which all pressure tanks 5 are arranged, so that the water pressure detection device can be freely moved to the product assembly line, which can save a lot of time in moving products when testing large quantities of products. A water tank 12 is also arranged on the movable bracket 11, and the water tank 12 is connected to the drain valve 8. The water discharged during the test is discharged into the water tank 12 through the drain valve 8, and is centrally processed after accumulating a certain amount.

[0031] The movable bracket 11 is also provided with a pressing mechanism 13, see Figure 2 As shown, the pressing mechanism 13 is a screw rod 131 threadedly connected to the movable bracket 11. By rotating the screw rod 131, the bottom of the screw rod 131 is pressed against the sealing cover 6 to prevent the sealing cover 6 from being opened due to excessive pressure. A sealing plug 14 is provided between the sealing cover 6 and the tank opening of the pressure tank 5 to improve the sealing performance. Figure 3 As shown, the sealing plug 14 and the mouth of the pressure tank 5 are both conical structures. When the sealing cover 6 squeezes the sealing plug 14, the sealing plug 14 will fit more and more closely with the mouth of the pressure tank 5, which can effectively prevent leakage from the mouth of the pressure tank 5.

[0032] Working principle:

[0033] First, place the workpiece 16 to be tested into the pressure tank 5, then fill the tank with water, then press in the sealing plug 14, cover the sealing cover 6, and then use an electric tool to unscrew the screw 131 to firmly support the sealing cover 6, then connect the air source to the air inlet valve 2 and the pressure regulating valve 10, and then open the branch valve 1 4 and the branch valve 2 9. After the pressure regulating valve 10 adjusts the pressure, the pressure in the entire detection device will remain constant. When a problem occurs with a workpiece 16 to be tested during the test, just close the branch valve 1 4 and the branch valve 2 9 on the pressure tank 5, and the problem workpiece inside can be taken out for testing. After the test is completed, close the air inlet valve 2, disconnect the air source, open the pressure exhaust valve 3, and reduce the pressure inside the system. Then, you can open the sealing cover 6 and take out the workpiece 16 to be tested.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
