[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, please refer to Figures 1 to 4 This utility model provides a technical solution: a non-destructive testing device, including an air storage cylinder 1. A standard pressure gauge 101 is fixedly installed on the top left side of the air storage cylinder 1. A first air outlet pipe 102 is fixedly installed on the top right side of the air storage cylinder 1. A connecting pipe 103 is fixedly installed on the inner wall of the first air outlet pipe 102. A first sealing gasket 104 is fixedly sleeved on the outer surface of the connecting pipe 103. The bottom of the first sealing gasket 104 is fixedly installed on the top of the first air outlet pipe 102. A pressure gauge 105 to be tested is movably sleeved on the outer surface of the connecting pipe 103. The bottom of the pressure gauge 105 to be tested is movably connected to the first sealing gasket 104. On the top of the pad 104, grooves 106 are provided on both sides of the outer surface of the first air outlet pipe 102. A sleeve 107 is movably fitted on the outer surface of the first air outlet pipe 102. Slider blocks 108 are fixedly installed on both sides of the inner wall of the sleeve 107. The outer surfaces of the two sliders 108 are slidably connected to the inner surface of the grooves 106. A second sealing gasket 109 is fixedly installed on the inner wall of the sleeve 107. The inner surface of the second sealing gasket 109 is movably connected to the outer surface of the first air outlet pipe 102. Two bolts 110 are threadedly connected to both sides of the inside of the sleeve 107. A second air outlet pipe 111 is fixedly installed at the bottom of the air storage cylinder 1.

[0031] In this embodiment, the operator first picks up the pressure gauge 105 to be tested, places it on top of the first vent pipe 102, and presses down on the pressure gauge 105 so that it fits onto the outer surface of the connecting pipe 103, with the bottom of the pressure gauge 105 adhering to the top of the first sealing gasket 104. Then, the sleeve 107 is pulled upward, causing the slider 108 to slide upward inside the groove 106, simultaneously causing the second sealing gasket 109 to slide on the outer surface of the first vent pipe 102. When the second sealing gasket 109 slides to a certain extent, it will cover the bottom of the first sealing gasket 104 and the pressure gauge 105. Then, the operator rotates the bolts 110 to tighten the bolts 110. One end of the sleeve 107 is attached to the outer surface of the first outlet pipe 102, and the other two bolts 110 are attached to the outer surface of the pressure gauge 105 to be tested, so as to fix the position of the sleeve 107. By connecting the pipe 103 and the sleeve 107, not only can the sealing between the pressure gauge 105 to be tested and the first outlet pipe 102 be ensured, but when the second sealing gasket 109 slides and wraps around the first sealing gasket 104 and the bottom of the pressure gauge 105 to be tested, a more effective sealing ring can be formed, which can effectively prevent gas leakage, thereby ensuring the stability and accuracy of pressure during non-destructive testing. At the same time, fixing by rotating the bolts 110 can avoid complicated operation steps, improve work efficiency, and save installation and disassembly time.

[0032] Example 2, as Figures 1 to 4 As shown, a one-way valve 112 is installed inside the second air outlet pipe 111. A workbench 2 is fixedly installed on the outer surface of the air storage cylinder 1. A pump 201 is fixedly installed on the top left side of the workbench 2. A first air inlet pipe 202 is fixedly installed on the right side of the pump 201. The bottom of the first air inlet pipe 202 is fixedly installed on the top of the workbench 2. A digital pressure controller 203 is fixedly installed on the right side of the first air inlet pipe 202. A second air inlet pipe 204 is fixedly installed on the right side of the digital pressure controller 203. The other end of the second air inlet pipe 204 is fixedly installed on the left side of the air storage cylinder 1.

[0033] In this embodiment, during use, after the pressure gauge 105 to be tested is fixed, the operator can first activate the digital pressure controller 203 and set a value to control the air pressure entering the air storage cylinder 1. Then, through the power supply system of the pump 201 on the workbench 2, the pump 201 is activated, enabling it to inject air into the first air intake pipe 202 and transport the air, allowing it to enter the air storage cylinder 1 through the digital pressure controller 203 and the second air intake pipe 204. Once the air enters the air storage cylinder 1, the operator can observe the pressure on the standard pressure gauge 1. The monitoring accuracy of the pressure gauge 105 is tested by comparing the value of the standard pressure gauge 101 with that of the pressure gauge 105. After the test is completed, the personnel can open the one-way valve 112 to allow the air inside the air storage tank 1 to flow out through the second air outlet pipe 111. Through the structure of the first air inlet pipe 202 and the digital pressure controller 203, high-precision pressure gauge testing can be achieved not only by comparing the standard pressure gauge 101 with the pressure gauge 105, but also by automatically testing the accuracy of the pressure gauge 105, reducing the complexity of manual operation.

[0034] Working principle: In use, the operator first picks up the pressure gauge 105 to be tested, places it on top of the first vent pipe 102, and presses down the pressure gauge 105 so that it fits onto the outer surface of the connecting pipe 103, and the bottom of the pressure gauge 105 is in contact with the top of the first sealing gasket 104. Then, the sleeve 107 is pulled upward, causing the slider 108 to slide upward inside the groove 106, and simultaneously causing the second sealing gasket 109 to slide on the outer surface of the first vent pipe 102. When the second sealing gasket 109 slides to a certain extent, it will cover the bottom of the first sealing gasket 104 and the pressure gauge 105. Then, the operator rotates the bolt 110 to loosen two of the bolts 11. One end of the sleeve 107 is attached to the outer surface of the first outlet pipe 102, and the other two bolts 110 are attached to the outer surface of the pressure gauge 105 to be tested, so as to fix the position of the sleeve 107. By connecting the pipe 103 and the sleeve 107, not only can the sealing between the pressure gauge 105 to be tested and the first outlet pipe 102 be ensured, but when the second sealing gasket 109 slides and wraps around the first sealing gasket 104 and the bottom of the pressure gauge 105 to be tested, a more effective sealing ring can be formed, which can effectively prevent gas leakage, thereby ensuring the stability and accuracy of pressure during non-destructive testing. At the same time, fixing by rotating the bolts 110 can avoid complicated operation steps, improve work efficiency, and save installation and disassembly time. In use, after the pressure gauge 105 is fixed in place, the operator can first activate the digital pressure controller 203 and set a value to control the air pressure entering the air storage tank 1. Then, through the power supply system of the pump 201 on the workbench 2, the pump 201 is activated, allowing it to inject air into the first air intake pipe 202 and transport the air, enabling it to enter the air storage tank 1 through the digital pressure controller 203 and the second air intake pipe 204. Once the air enters the air storage tank 1, the operator can monitor the pressure by observing the pressure gauge 101 and the pressure gauge 205. The monitoring accuracy of the pressure gauge 105 is tested by observing the changes in its value. After the test is completed, the personnel can open the one-way valve 112 to allow the air inside the air storage tank 1 to flow out through the second air outlet pipe 111. Through the structure of the first air inlet pipe 202 and the digital pressure controller 203, high-precision pressure gauge testing can be achieved not only by comparing the standard pressure gauge 101 with the pressure gauge 105 under test, but also by automatically testing the accuracy of the pressure gauge 105 under test, reducing the complexity of manual operation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
