Description

Technical Field

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

[0002] Pipeline airtightness testing is an important testing method to ensure the good sealing of pipeline systems and prevent gas leakage. After the pipeline is manufactured, its airtightness must be tested to check whether the pipeline is completely sealed before subsequent assembly can be carried out.

[0003] Utility model patent application number 202420110040.0 discloses a pipe airtightness testing fixture, belonging to the field of pipe testing technology. The pipe airtightness testing fixture includes a water tank, a mounting frame inside the water tank, driving parts for lateral movement of the mounting frame on both sides of the water tank, a flipping mechanism for rotating an air injection pipe below the mounting frame, a movable frame above the water tank, and a marking mechanism for marking leaks in the pipe below the movable frame.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when the device is used, the pipeline is placed in water to test the pipeline's seal. This testing method is not accurate enough and cannot accurately find the location of the leak, resulting in poor testing results. In addition, when changing different pipelines, water is continuously carried out of the water tank and spilled on the ground, which can easily make the ground wet and slippery, posing a risk of slipping.

[0005] Therefore, it is necessary to invent a pipe airtightness testing tool to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe airtightness testing fixture. By setting up arc-shaped clamping plates, two of which are symmetrically arranged, they can be respectively set on the upper and lower sides of the pipe and seal it, so that a sealed cavity can be formed on the outer surface of the pipe, which facilitates the airtightness testing. The arc-shaped clamping plates can move left and right on the pipe, thereby quickly and accurately identifying the leakage point on the pipe, improving the testing effect. This solves the problem mentioned in the background art, which requires the pipe to be placed in water to test the pipe airtightness. This testing method is not accurate enough and cannot accurately find the location of the leak, resulting in poor testing effect. In addition, when changing different pipes, water is constantly carried out from the water tank and spilled on the ground, which can easily make the ground wet and slippery, posing a risk of slipping.

[0031] like Figures 1-4 As shown, a pipe airtightness testing fixture disclosed herein may include a base plate 1, a first groove 11 is provided on the inner side of the front end of the base plate 1, and second grooves 12 are symmetrically provided on both sides of the first groove 11.

[0032] Two support plates 4 are symmetrically arranged at the front end of the substrate 1. A cylinder 5 is fixedly connected to the outer side of the support plate 4, and an arc-shaped clamping plate 6 is fixedly connected to the output end of the cylinder 5.

[0033] A buzzer 7 is provided at the top of the arc-shaped clamping plate 6, a first sealing gasket 61 is provided at both ends of the arc-shaped clamping plate 6, a groove 63 is provided on the inner side of the arc-shaped clamping plate 6, and a second sealing gasket 62 is provided at the top of the arc-shaped clamping plate 6.

[0034] Therefore, two support plates 4 are symmetrically arranged. The top of the upper support plate 4 is fixedly connected to a cylinder 5, and the bottom of the lower support plate 4 is fixedly connected to a cylinder 5. Similarly, two arc-shaped clamping plates 6 are symmetrically arranged and correspondingly positioned, which can be set at the upper and lower ends of the pipeline. The cylinder 5 can drive the arc-shaped clamping plates 6 to move. By setting a first sealing gasket 61 and a second sealing gasket 62 on the inner side of the arc-shaped clamping plates 6, it is easy to set them on the outside of the pipeline, which can effectively increase the sealing performance and facilitate subsequent testing. By setting the groove 63, after the two arc-shaped clamping plates 6 are completely pressed against the outside of the pipeline, a sealed cavity can be formed on the outer periphery of the pipeline. A pressure sensor is set on the inner side of the arc-shaped clamping plate 6 at the top. If a pressure change occurs, that is, when air leakage occurs, the pressure in the cavity increases, which triggers the pressure sensor. A buzzer 7 is set on the top of the arc-shaped clamping plate 6. The pressure sensor and the buzzer 7 are electrically connected, which can be used to remind the staff that there is an air leakage in the pipeline, thus improving the efficiency of the test.

[0035] like Figure 1 As shown, in a preferred embodiment, a fixing block 2 is fixedly connected to one side of the front end of the substrate 1, an air inlet pipe 21 is fixedly connected to one side of the fixing block 2, a connecting pipe 22 is fixedly connected to the other side of the fixing block 2, a limit ring 23 is provided on the outside of the connecting pipe 22, and the air inlet pipe 21 and the connecting pipe 22 are interconnected.

[0036] Therefore, by setting a fixing block 2, which is fixedly connected to the front end of the substrate 1, the air inlet pipe 21 can be used to connect to an externally installed air supply pipe to ventilate the pipe to be tested. By setting a connecting pipe 22, the pipe to be tested can be sleeved on the outside of the connecting pipe 22, which facilitates subsequent testing.

[0037] like Figure 1 As shown in this disclosure, a movable block 3 is provided on the other side of the front end of the substrate 1. The movable block 3 is slidably connected to the inner side of the first slide groove 11. A connecting pipe 22 is also provided on the side of the movable block 3 near the fixed block 2.

[0038] Therefore, by setting the movable block 3, the movable block 3 can slide at the front end of the substrate 1, so as to move closer to or away from the fixed block 2. The position of the movable block 3 can be adjusted according to the length of the detection pipeline. The movable block 3 is also provided with a connecting pipe 22 on the side close to the fixed block 2, so as to connect one end of the pipeline with the connecting pipe 22 for sealing, so that the other end of the pipeline will not leak air.

[0039] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the support plate 4 is slidably connected to the inner side of the second slide groove 12, the end of the support plate 4 is fixedly connected to the fixing plate 8, the other side of the fixing plate 8 is fixedly connected to the threaded block 81, the inner side of the threaded block 81 is provided with a threaded hole 811, and both the fixing plate 8 and the threaded block 81 are slidably connected to the inner side of the base plate 1.

[0040] Therefore, the support plates 4 set at the upper and lower ends slide on the inner side of the two second slide grooves 12 respectively, and are fixedly connected to the fixed plate 8. The movement of the fixed plate 8 can effectively drive the two support plates 4 to move.

[0041] like Figure 4 As shown in this disclosure, a drive motor 9 is fixedly connected to the side of the substrate 1, and a lead screw 91 is connected to the output end of the drive motor 9. The lead screw 91 and the threaded block 81 are threadedly connected to each other.

[0042] Therefore, by setting up a drive motor 9, the drive motor 9 can effectively drive the lead screw 91 to rotate. The lead screw 91 and the threaded hole 811 are set in correspondence with each other, so the rotation of the lead screw 91 can effectively cause the threaded block 81 to rotate, thereby driving the threaded block 81 to move. The threaded block 81 is fixed to the fixed plate 8, so the movement of the threaded block 81 can effectively drive the fixed plate 8 to move.

[0043] In practical use, one end of the pipeline is sleeved on the outside of the connecting pipe 22 on one side of the fixed block 2. The moving block 3 is moved so that the other end of the pipeline is sleeved on the inside of the connecting pipe 22 on one side of the moving block 3, ensuring that the pipelines on both sides are completely sealed with the connecting pipe 22. The external gas supply pipe and the gas receiving pipe 21 are connected to each other, which facilitates the gas supply to the inside of the pipeline.

[0044] The drive motor 9 is started to move the fixed plate 8, which in turn moves the bearing plate 4 and the arc-shaped clamping plate 6. The detection starts from the point near the fixed block 2. The cylinder 5 is started to move the arc-shaped clamping plate 6 closer to the pipeline, so that the arc-shaped clamping plate 6 is completely pressed against the outside of the pipeline. By setting the groove 63, after the two arc-shaped clamping plates 6 are completely pressed against the outside of the pipeline, a sealed cavity can be formed on the outer periphery of the pipeline. A pressure sensor is set on the inner side of the arc-shaped clamping plate 6 at the top. If there is a pressure change, that is, when there is a leak, the pressure in the cavity increases, which triggers the pressure sensor. A buzzer 7 is set on the top of the arc-shaped clamping plate 6. The pressure sensor and the buzzer 7 are electrically connected, which can be used to remind the staff that there is a leak in the pipeline, thus improving the detection efficiency.

[0045] After completing one test, the drive motor 9 is started again to move the arc-shaped clamping plate 6 to complete the subsequent testing of the pipeline.

[0046] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
