DETAILED DESCRIPTION

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] See also Figures 1-3 A pipeline weld defect identification device includes a base plate 1, a first sealing plate 2, a second sealing plate 3, a vacuum exhaust port joint gate 4 and a vacuum pressure gauge and joint 5 respectively provided on the second sealing plate 3, a pressure relief interface gate 6 provided on the vacuum pressure gauge and joint 5, an adjustment mechanism provided on the top outer wall of the base plate 1, a positioning mechanism provided in the second sealing plate 3, and mounting mechanisms provided on the first sealing plate 2 and the second sealing plate 3;

[0033] Among them, the adjustment mechanism includes two second adjustment rods 24 fixedly installed on the top outer wall of the base plate 1, two support seats 25 fixedly installed on one end of the top of the two second adjustment rods 24, and the two support seats 25 are fixedly connected to the first sealing plate 2, and second threaded holes 26 are respectively opened on the outer surface of one side of the two second adjustment rods 24, two second adjustment bolts 27 screwed into the two second threaded holes 26, and the first sealing plate 2 and the second sealing plate 3 are both made of transparent hard material.

[0034] By connecting the vacuum pump connector and the vacuum exhaust port connector gate 4, close the pressure relief interface gate 6 and start the vacuum pump to exhaust, and observe the values ​​of the vacuum pressure gauge and the connector 5 at the same time. When the pressure drops to the preset air pressure value, close the vacuum exhaust port connector gate 4 and stop the pump to stabilize the pressure for three to five minutes. Observe the weld surface through the transparent first sealing plate 2 and the second sealing plate 3. When bubbles are found in the weld, it can be determined that there is a leakage point in the weld. At this time, slowly open the pressure relief interface gate 6 to make the pressure inside the first sealing plate 2 and the second sealing plate 3 consistent with the external pressure.

[0035] During use, by pulling the support seat 25 upward, the support seat 25 moves upward and drives the second adjusting rod 24 to stretch upward as well. At this time, the height of the first sealing plate 2 and the second sealing plate 3 can be adjusted, so that by rotating the second adjusting bolt 27, the position of the second adjusting rod 24 and the first sealing plate 2 and the second sealing plate 3 can be fixed and limited, and then the height of the identified pipe can be adjusted, thereby facilitating the observation and identification of the bottom of the pipe at a later time, improving the convenience during use and the flexibility during operation.

[0036] Reference Figures 2-4 The positioning mechanism includes two fixing seats 19 symmetrically fixedly installed in the second sealing plate 3, a first adjusting rod 20 fixedly installed on the outer wall of the bottom of the fixing seat 19, a positioning plate 21 fixedly installed at one end of the first adjusting rod 20, a first threaded hole 22 opened on the outer surface of one side of the first adjusting rod 20, and a first adjusting bolt 23 screwed into the first threaded hole 22. The first adjusting rod 20 and the second adjusting rod 24 are both composed of a sleeve and a sleeve rod, and are interlocked with each other.

[0037] During use, by pulling the positioning plate 21 upward, the positioning plate 21 moves upward and compresses the first adjusting rod 20. At this time, the pipe to be identified can be placed in the first sealing plate 2 and the second sealing plate 3, and then the positioning plate 21 is moved downward, so that the positioning plate 21 contacts the pipe, and then the first adjusting bolt 23 is rotated, so that the position of the positioning plate 21 and the pipe can be positioned and installed, thereby preventing the pipe from shaking during identification.

[0038] Reference Figures 1-2The mounting mechanism includes a first mounting ear 7 and a second mounting ear 8 respectively fixedly mounted on the outer surfaces of both sides of the first sealing plate 2 and the second sealing plate 3, and the first mounting ear 7 and the second mounting ear 8 are arranged in parallel, have the same length, and are opened on the outer wall of the top of the second mounting ear 8. Two telescopic rods 10 are symmetrically fixedly mounted in the mounting groove 9, two telescopic springs 11 are sleeved on the two telescopic rods 10, a first oblique block 12 respectively fixedly mounted on one end of the two telescopic rods 10, a second oblique block 13 fixedly mounted on the outer wall of the bottom of the first mounting ear 7, and the second oblique blocks 13 are adapted to the two first oblique blocks 12, the two first oblique blocks 12 are slidably mounted in the same mounting groove 9, a positioning groove 17 opened on the top of the first sealing plate 2, a positioning block 18 slidably mounted in the positioning groove 17, and the positioning block 18 is fixedly connected to the second sealing plate 3, a sliding groove 14 opened in the mounting groove 9, a sliding rod 15 slidably mounted in the sliding groove 14, and the sliding rod 15 is fixedly connected to one of the first oblique blocks 12, and a pull plate 16 fixedly mounted on the outer wall of the bottom of the sliding rod 15;

[0039] When in use, the first sealing plate 2 and the second sealing plate 3 are spliced ​​together. At this time, the second oblique block 13 on the second sealing plate 3 will enter the second mounting ear 8, and press the two first oblique blocks 12 away from each other, and compress the telescopic rod 10 and the telescopic spring 11, so that the second oblique block 13 and the two first oblique blocks 12 cooperate to complete the sealing installation of the first sealing plate 2 and the second sealing plate 3. Therefore, the installation and fixation can be carried out directly, which improves the convenience during use. By pulling the pull plate 16 and driving the sliding rod 15 and one of the first oblique blocks 12 to move, the first sealing plate 2 and the second sealing plate 3 are separated, and then the leaking part is welded.

[0040] The implementation principle of the present application is as follows: when in use, the first sealing plate 2 and the second sealing plate 3 are first spliced ​​together. At this time, the second oblique block 13 on the second sealing plate 3 will enter the second mounting ear 8, and press the two first oblique blocks 12 away from each other, and compress the telescopic rod 10 and the telescopic spring 11. As a result, the second oblique block 13 and the two first oblique blocks 12 cooperate to complete the sealing installation of the first sealing plate 2 and the second sealing plate 3. Therefore, the installation and fixation can be carried out directly, which improves the convenience during use.

[0041] By pulling the positioning plate 21 upward, the positioning plate 21 moves upward and compresses the first adjusting rod 20. At this time, the pipe to be identified can be placed in the first sealing plate 2 and the second sealing plate 3. Then, the positioning plate 21 is moved downward and makes contact with the pipe. Then, the first adjusting bolt 23 is rotated to position the positioning plate 21 and the pipe, thereby preventing the pipe from shaking during identification.

[0042] By pulling the support seat 25 upwards, the support seat 25 moves upwards and can pull the second adjusting rod 24 upwards, at this time, the height of the first sealing plate 2 and the second sealing plate 3 can be adjusted, the second adjusting bolt 27 can be rotated, the position of the second adjusting rod 24 and the first sealing plate 2 and the second sealing plate 3 can be fixed and limited, and the height of the identified pipeline can be adjusted, so that the bottom of the pipeline is convenient to observe and identify in the later period, and the convenience in use and the flexibility in operation are improved.

[0043] At this time, the two ends of the first sealing plate 2 and the second sealing plate 3 are sealed and installed through the external sealing ring, then the vacuum pump joint and the vacuum air outlet joint gate 4 are connected, the pressure relief interface gate 6 is closed, the vacuum pump is started to pump, and the values of the vacuum pressure gauge and the joint 5 are observed. When the pressure decreases to the preset air pressure value, the vacuum air outlet joint gate 4 is closed and the pump is stopped to stabilize the pressure for three to five minutes. The welding seam surface is observed through the transparent first sealing plate 2 and the second sealing plate 3. When bubbles are found at the welding seam, it can be judged that there is a leakage point in the welding seam. At this time, the pressure inside and outside the first sealing plate 2 and the second sealing plate 3 is consistent by slowly opening the pressure relief interface gate 6, pulling the pull plate 16, and moving the sliding rod 15 and one of the first inclined blocks 12, so that the first sealing plate 2 and the second sealing plate 3 are separated, and then the leakage position is welded and repaired.

[0044] The above are preferred embodiments of the present application, and are not limited to the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
