Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure resistance detection, in particular to a pressure pipeline pressure resistance detection device. Background Art

[0002] Pressure pipelines refer to all pipelines that bear internal or external pressure. Before use, the pressure bearing pressure of the pressure pipeline needs to be tested. When conducting pressure resistance test on the pressure pipeline, high-pressure gas is added to the pressure pipeline through a pressure tester, and the pressure in the high-pressure gas reaches the peak value that can be tolerated, and it is left to stand for a period of time to test whether the pressure resistance of the pressure pipeline meets the standard.

[0003] However, in the existing technology, some pressure pipes have poor pressure resistance. As the pressure machine pressurizes the inside of the pipe, it exceeds the load range, causing the pressure pipe under test to rupture or even explode, which will cause injuries to test personnel. After the pipe is burst by pressure, debris and aqueous solution will be scattered everywhere, increasing the cleaning work of the staff.

[0004] At the same time, in the existing technology, when the pressure pipeline is pressure tested, it is mainly judged by visual observation. Although this method is relatively simple and easy to operate, when the degree of expansion of the pressure pipeline surface is small, it may not be observed by the naked eye, which can easily lead to misjudgment and affect the accuracy of the detection.

[0005] For example, Chinese utility model patent publication number CN212748560U discloses a pressure pipe pressure test device. The patent states in its technical problem as follows:

[0006] At present, when judging the surface condition of pressure pipes (generally the expansion phenomenon on the surface of pressure pipes), visual observation is mainly used. Although this method is relatively simple and convenient to operate, when the degree of expansion of the pressure pipe surface is small, the naked eye may not be able to observe it, resulting in misjudgment and affecting the accuracy of detection.

[0007] Chinese utility model patent publication number CN220819678U discloses a pressure pipe pressure test device. The patent states in its technical section:

[0008] During the testing process, some pipelines have poor pressure resistance. As the pressure tester presses the inside of the pipeline, it exceeds the load-bearing range and will cause the pipeline to rupture or even explode, causing injuries to the test personnel. After the pipeline is burst by pressure, fragments and aqueous solutions will spread everywhere, increasing the cleaning work of the staff.

[0009] Based on this, a pressure pipeline pressure resistance detection device is proposed. Summary of the Invention

[0010] (1) Technical problems solved

[0011] In response to the shortcomings of the prior art, the present invention provides a pressure pipe pressure test device to solve the problems raised in the background art: in the prior art, some pressure pipes have poor pressure resistance.

After the pipe is burst by pressure, debris and aqueous solution will be scattered everywhere, increasing the cleaning work of the staff.

[0012] At the same time, in the existing technology, when the pressure pipeline is pressure tested, it is mainly judged by visual observation. Although this method is relatively simple and convenient to operate, when the degree of expansion of the pressure pipeline surface is small, it may not be observed by the naked eye, which can easily lead to misjudgment and affect the accuracy of the detection.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] Example 1

[0056] In the prior art, some pressure pipes have poor pressure resistance. As the pressure machine pressurizes the inside of the pipe, the pressure exceeds the load range, causing the pressure pipe under test to rupture or even explode, causing injuries to test personnel. After the pipe is burst by pressure, debris and aqueous solution will be scattered everywhere, increasing the cleaning work of the staff.

[0057] At the same time, in the existing technology, when the pressure pipeline is pressure tested, it is mainly judged by visual observation. Although this method is relatively simple and easy to operate, when the degree of expansion of the pressure pipeline surface is small, it may not be observed by the naked eye, which can easily lead to misjudgment and affect the accuracy of the detection.

[0058] Based on this, in order to solve the above technical problems, the following technical solutions are now adopted, as follows:

[0059] like Figure 1-2 as well as Figure 4 As shown, the utility model provides a technical solution:

Both sets of adjustable blocking mechanisms 40 have a blocking portion and an adjusting portion. The blocking portions of the two sets of adjustable blocking mechanisms 40 are disposed within the inner cavity of the detection box 10, while the adjusting portions of the two sets of adjustable blocking mechanisms 40 are disposed outside the detection box 10.

[0071] At the same time, if the pressure pipe 80 has a gap and leaks, the leak can be detected by detecting the water in the box 10. When the leaked gas enters the water, several bubbles will be generated. By observing whether bubbles are generated, it can be determined whether there is a gap in the pressure pipe 80, thereby avoiding the problem of misjudgment due to visual observation, which affects the accuracy of the detection.

[0072] If the pressure pipe 80 bursts due to high-pressure gas, the detection box 10 can provide protection to prevent fragments from flying everywhere, thereby ensuring the safety of the test personnel and reducing the cleaning workload of the staff.

[0081] The blocking disk 401 can be displaced by rotating the hand wheel 405 . When the blocking disk 401 is displaced, the two guide rods 406 can keep the blocking disk 401 stable.

The two support bases 90 are used to support the pressure pipe 80.

[0092] Specifically, the two supporting bases 90 are both rubber bases.

[0105] The sealing parts of the two sets of adjustable sealing mechanisms 40 can both seal the openings at both ends of the pressure pipe 80;

[0106] After the sealing parts of the two sets of adjustable sealing mechanisms 40 seal the openings at both ends of the pressure pipe 80, water can be filled in the inner cavity of the detection box 10, and the water level can be as high as to submerge the pressure pipe 80. The inflatable structure is installed on one set of adjustable sealing mechanisms 40, and one end of the inflatable structure extends to the outside of the detection box 10. The inflatable structure is used to be connected to a press. After the press is connected to the inflatable structure (not shown in the figure), high-pressure gas can enter the pressure pipe 80 through the inflatable structure, and the pressure resistance of the pressure pipe 80 is tested by the high-pressure gas injected by the press.

[0107] At the same time, if there is a gap in the pressure pipe 80 and it leaks, the leak can be detected by testing the water in the box 10. When the leaked gas enters the water, a number of bubbles will be generated. By observing whether there are bubbles, it can be determined whether there is a gap in the pressure pipe 80, thereby avoiding the problem of misjudgment caused by visual observation and affecting the accuracy of detection.

The high-pressure gas generated by the pressurizing machine can be input into the gas filling pipe 60 through the inflation conduit, then flow into the gas filling port 50 through the gas filling pipe 60, and then flow into the inner cavity of the pressure pipe 80 through the gas filling port 50.

[0117] A gas detection structure is installed on the top of the box cover 20 corresponding to the exhaust groove 201.

[0118] The gas detection structure can detect gas leakage from the pressure pipe 80 during the pressure test. The gas detection structure includes two U-shaped clamps 100, which are fixedly mounted on the top of the box cover 20 and correspond to the two ends of the exhaust groove 201.
