Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing testing technology, and more specifically, to a pipeline-based sealing testing device. Background Technology

[0002] Pipeline sealing tests are a crucial step in ensuring a leak-free piping system. Hydrostatic testing is one of the most common methods. Leaks are detected by filling the piping system with water and gradually increasing the pressure, observing whether the pressure remains stable. Pressure gauges can be used to monitor pressure changes. If the pressure remains stable for a certain period, it usually indicates a good pipe seal. However, hydrostatic testing primarily detects larger leaks and may be less sensitive to minor leaks. Some minor leaks may not be detected by hydrostatic testing. For minor leaks, a leak detection solution is often applied or sprayed onto the pipe surface and observed for bubbles. The presence of bubbles indicates a leak. This method is suitable for detecting small leaks.

[0003] When using leak detectors to test the sealing of pipelines, the leak detectors need to be sprayed or applied to the pipeline surface by personnel, and then the presence of air bubbles on the pipeline surface is observed to check the pipeline's sealing performance. However, when personnel spray the leak detectors, uneven spraying is inevitable, which reduces the accuracy of the pipeline sealing test. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown in Figure 4, a pipe-based sealing test device includes a base plate 1. Support side plates 3 are fixedly installed on both sides of the top of the base plate 1. A mounting frame 2 is fixedly installed on the top of the base plate 1 and on the back of the support side plates 3. A test tube 4 is provided on the top of the support side plates 3. A spraying mechanism 5 is provided on the back of the mounting frame 2. A movable plate 6 is provided on the top of the mounting frame 2. A liquid storage tank 7 is fixedly installed on the top of the movable plate 6 and on one side of the liquid storage tank 7. The input end of the liquid pump 8 is connected to the liquid storage tank 7, and the output end of the liquid pump 8 is connected to a connecting pipe 9. An exhaust pipe 13 is connected to the right side of the test tube 4, and an air inlet pipe 14 is connected to the left side of the test tube 4. An air pump 15 is fixedly installed on one side of the support side plates 3, and the output end of the air pump 15 is connected to the air inlet pipe 14.

[0023] The effects achieved by the above components are as follows: by setting the support side plate 3 to support the test tube 4, the stability of the test tube 4 when spraying the leak detection agent is improved; by setting the spraying mechanism 5 to spray the leak detection agent on the test tube 4, the spraying effect and uniformity of the leak detection agent are improved, avoiding the problem of poor spraying effect by workers, and improving the test accuracy of the test tube 4 in detecting the sealing performance; under the action of the liquid pump 8, the leak detection agent inside the liquid storage tank 7 is delivered to the spraying mechanism 5 through the connecting pipe 9, and then the leak detection agent is evenly sprayed onto the surface of the test tube 4 through the spraying mechanism 5; under the action of the air pump 15, after the leak detection agent is sprayed, air is injected into the interior of the test tube 4, and the presence of air bubbles on the surface of the test tube 4 is observed to determine the sealing performance of the test tube 4.

[0024] like Figure 3 As shown, the spraying mechanism 5 includes an annular tube 501, which is sleeved on the surface of the test tube 4. The annular tube 501 has uniformly distributed nozzles 502 on its inner side. A limiting block 503 is fixedly installed on the back of the annular tube 501. A connecting rod 504 is fixedly installed on the back of the limiting block 503. A motor 505 is fixedly installed on the back of the mounting frame 2. A reciprocating groove 506 is fixedly installed at the output end of the motor 505. The bottom of the connecting rod 504 is located in the guide groove on the surface of the reciprocating groove 506. A fixing rod 507 is fixedly installed on the top of the limiting block 503 and on the back of the mounting frame 2. The other side of the fixing rod 507 is fixedly connected to the moving plate 6. The bottom of the connecting pipe 9 is connected to the top of the annular tube 501.

[0025] The effect achieved by the above components is as follows: by setting a motor 505 to drive the reciprocating groove cylinder 506 to rotate, the reciprocating groove cylinder 506 drives the connecting rod 504 to move, so that the connecting rod 504 moves back and forth on the surface of the reciprocating groove cylinder 506, and then the connecting rod 504 drives the limiting block 503 and the annular tube 501 to move back and forth, thereby improving the uniformity of the spraying of the nozzle 502 on the surface of the test tube 4 and avoiding poor spraying effect by the workers. The limiting block 503 drives the fixed rod 507 to move, the fixed rod 507 drives the moving plate 6 to move, and thus the moving plate 6 drives the connecting tube 9 to move, so that the connecting tube 9 and the annular tube 501 move at the same speed.

[0026] like Figure 1 As shown, the mounting bracket 2 has a first limiting groove inside, the back of the limiting block 503 passes through the limiting groove, the mounting bracket 2 has a second limiting groove on the top, and the connecting pipe 9 passes through the second limiting groove.

[0027] The effect achieved by the above components is as follows: by setting the first limiting groove to limit the limiting block 503, the stability of the limiting block 503 when sliding is improved, and the connecting pipe 9 is limited under the action of the second limiting groove.

[0028] like Figure 4 As shown, two rails 10 are fixedly installed on the top of the mounting bracket 2 and at the bottom of the movable plate 6. Slider 11 is fixedly installed on both sides of the bottom of the movable plate 6, and the slider 11 is located inside the rails 10.

[0029] The effect achieved by the above components is as follows: by setting the track 10 and the slider 11 to cooperate with each other to support and limit the moving plate 6, the moving plate 6 is prevented from shifting during movement, and the relative position of the connecting pipe 9 and the spraying mechanism 5 is guaranteed.

[0030] like Figure 4 As shown, the bottom of the slider 11 has a groove, and a pulley 12 is rotatably connected inside the groove. The surface of the pulley 12 contacts the bottom of the inner side of the track 10.

[0031] The effect achieved by the above components is as follows: by setting the pulley 12 to reduce the friction of the slider 11 on the inside of the track 10, the smoothness of the movement of the moving plate 6 is improved, and the slider 11 is prevented from getting stuck on the inside of the track 10.

[0032] like Figure 2 As shown, both the end of the air intake pipe 14 and the output end of the air pump 15 are equipped with connecting flanges.

[0033] The effect achieved by the above components is that the connection flange facilitates the connection and disconnection of the output end of the air pump 15 to the end of the air inlet pipe 14.

[0034] like Figure 5 As shown, a retaining plate 17 is provided on the top of the support side plate 3, and a placement groove 16 is provided on the top of the support side plate 3 and the bottom of the retaining plate 17. The test tube 4 is located inside the placement groove 16. An installation screw 18 is provided on the top of the retaining plate 17, and a threaded groove 19 is provided on the top of the support side plate 3. The bottom of the installation screw 18 extends into the threaded groove 19 and is threadedly connected to the threaded groove 19.

[0035] The effect achieved by the above components is as follows: by setting the mounting screw 18 and the threaded groove 19 to cooperate with each other to install and fix the clamping plate 17, the clamping plate 17 improves the limiting effect of the test tube 4 and prevents the test tube 4 from shifting during the test.

[0036] The working principle of this pipeline-based sealing test device:

[0037] The test tube 4 is inserted between the support side plate 3 and the clamping plate 17. The motor 505 drives the reciprocating groove cylinder 506 to rotate, which in turn drives the connecting rod 504 to move. This causes the connecting rod 504 to reciprocate on the surface of the reciprocating groove cylinder 506. The connecting rod 504 then drives the limiting block 503 and the annular tube 501 to reciprocate, improving the uniformity of the spray from the nozzle 502 onto the surface of the test tube 4 and preventing poor spraying results from workers. The limiting block 503 drives the fixing rod 507 to move. 7 drives the moving plate 6 to move, which in turn drives the connecting pipe 9 to move, so that the connecting pipe 9 moves at the same speed as the annular pipe 501. Under the action of the liquid pump 8, the leak detection agent inside the storage tank 7 is discharged and transported to the spraying mechanism 5 through the connecting pipe 9. The spraying mechanism 5 then evenly sprays the leak detection agent onto the surface of the test tube 4. Under the action of the air pump 15, after the leak detection agent is sprayed, air is injected into the interior of the test tube 4 to observe whether there are air bubbles on the surface of the test tube 4, so as to determine the sealing performance of the test tube 4.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
