Description

Technical Field

[0001] The utility model relates to the field of performance detection, in particular to a hydraulic pipe sealing detection device. Background Technique

[0002] Air tightness detection is a method for measuring gas leakage in containers, pipes, equipment or systems. This detection is crucial for ensuring the safety of industrial processes and environmental protection. The air tightness detection of hydraulic pipe fittings is one of the important steps to ensure that the pipeline system can work properly without leakage. During the processing of hydraulic pipes, hydraulic pipes with damages such as cracks and micropores are likely to be mixed into qualified products because they are not easily recognizable by operators with the naked eye, which will cause the qualification rate of hydraulic pipes to decrease.

[0003] Existing detection devices usually use one detection method to detect the sealing performance of hydraulic pipes. For example, just fill gas into the hydraulic pipe, then immerse the hydraulic pipe in a water tank, and then observe whether there are bubbles in the water in the water tank to judge the sealing performance of the hydraulic pipe. However, this method is prone to misjudgment, resulting in personnel misjudging hydraulic pipes with qualified sealing performance as unqualified, and there is a possibility of misjudgment. Therefore, we propose a hydraulic pipe sealing detection device that uses two detection methods for comparative detection to improve the accuracy of detection results. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that only one detection method is used to detect the sealing performance of hydraulic pipes, which is prone to misjudgment.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a hydraulic pipe sealing detection device, including an operating table and a pipe body. A water tank is placed on the top of the operating table, a base is fixed at the bottom of the water tank, the pipe body is placed on the base, two cylinders are symmetrically fixed on the top of the operating table, the output ends of the two cylinders respectively penetrate through the two side walls of the water tank and are fixed with pressing blocks, both pressing blocks are slidably connected in the water tank and sealing rings are fixed on the opposite surfaces, and the two sealing rings are in close contact with the two ends of the pipe body respectively. An air inlet pipe is arranged on one of the pressing blocks, an air delivery assembly for delivering gas with a certain pressure to the air inlet pipe is arranged on the water tank, a water circulation assembly for delivering water to the water tank is arranged on the operating table, a first pressure sensor is fixed on one surface of the other pressing block, and a display controller is arranged on the top of the operating table.

[0006] Preferably, the air delivery assembly includes a connecting pipe fixed above the water tank by a bracket, a second pressure sensor is installed on the surface of the connecting pipe, one end of the connecting pipe is fixed with a spring delivery pipe, and one end of the spring delivery pipe is fixedly communicated with the top end of the air inlet pipe.

The top end of the water pipe passes through the top of the operation table and is fixedly communicated with the bottom of the pool. An electromagnetic valve is installed on the surface of the water pipe. Both the electromagnetic valve and the water pump are electrically connected to the display controller.

[0010] Preferably, a water suction pipe is fixedly communicated between the input end of the water pump and the water outlet end of the water tank, and a water delivery pipe is fixedly communicated with the output end of the water pump.

At the same time, the air delivery assembly delivers air with a certain pressure to the hydraulic pipe, and the pressure data transmitted and the pressure data detected by the first pressure sensor in the hydraulic pipe will be transmitted to the display controller together, so that the operator can directly understand the pressure values at the two places from the screen for comparison and judgment.

Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 5 shown, the present utility model provides a hydraulic pipe sealing detection device, including an operating table 1 and a pipe body 4.

[0023] The effect achieved by the entire Embodiment 1 is that the pipe body 4 is clamped in the water tank 2, and then water is supplied from below the water tank 2, so that the water can slowly submerge the pipe body 4 without splashing water waves, bubbles and other factors that affect the judgment. The air delivery component 9 can deliver some compressed air to the pipe body 4, and the pressure value of the compressed air and the pressure value inside the pipe body 4 detected by the first pressure sensor 11 will be transmitted to the display controller 12 together, so that the personnel can directly understand the pressure values at the two places from the screen for comparison and judgment. That is, by observing the changes in the pressure values and the bubbles in the water, these two detection results can be used to comprehensively judge the sealing performance of the hydraulic pipe, improving the accuracy of the detection results.

[0024] Embodiment 2, as Figures 1 - 5 shown, the air delivery component 9 includes a connecting pipe 901 fixed above the water tank 2 by a bracket. A second pressure sensor 902 is installed on the surface of the connecting pipe 901. One end of the connecting pipe 901 is fixed with a spring delivery pipe 903, and one end of the spring delivery pipe 903 is fixedly communicated with the top end of the air inlet pipe 8; the first pressure sensor 11, the second pressure sensor 902 and the two cylinders 5 are all electrically connected to the display controller 12; the water circulation component 10 includes four support rods 1001 fixed at the bottom of the operating table 1. The bottom of the four support rods 1001 is fixed with a mounting plate 1002. A water tank 1003 and a water pump 1004 are respectively fixed on the top of the mounting plate 1002; the top of the water tank 1003 is fixedly communicated with a water pipe 1005. The top end of the water pipe 1005 passes through the top of the operating table 1 and is fixedly communicated with the bottom of the water tank 2. A solenoid valve 1006 is installed on the surface of the water pipe 1005. The solenoid valve 1006 and the water pump 1004 are both electrically connected to the display controller 12; the input end of the water pump 1004 is fixedly communicated with the water outlet end of the water tank 1003 by a water suction pipe 1007, and the output end of the water pump 1004 is fixedly communicated with a water delivery pipe 1008. The top end of the water delivery pipe 1008 passes through the top of the operating table 1 and is fixedly communicated with one side wall of the water tank 2; the centers of the pipe body 4 and the two pressing blocks 6 are on the same horizontal line, and the water tank 2 is transparent.

[0025] The effect achieved by the entire Embodiment 2 is that the second pressure sensor 902 can detect the pressure value of the compressed air input into the pipe body 4 for comparison with the pressure value inside the pipe body 4. The spring delivery pipe 903 is to cooperate with the movement of the pressing block 6. Under the cooperation of the solenoid valve 1006 and the water pump 1004, the water in the water tank 1003 can be recycled in the water tank 2, so that the personnel can observe whether small bubbles will be generated in the water through the transparent water tank 2. The pressing block 6 is adapted to the pipe body 4 on the placed base 3, and can smoothly seal both ends of the pipe body 4.

[0026] Working principle: When in use, first place the pipe body 4 to be detected on the base 3. Subsequently, two cylinders 5 are started simultaneously, driving two pressure blocks 6 to move towards the middle in the water tank 2 until the pressure blocks 6 clamp the pipe body 4 from both ends. With the cooperation of the sealing ring 7 and pressure, the two ends of the pipe body 4 can be sealed. At this time, the first pressure sensor 11 can monitor the pressure inside the pipe body 4 in real time and feedback the data to the display controller 12 for display. Personnel can then learn the initial pressure from the screen of the display controller 12. One end of the connecting pipe 901 is connected to the air outlet end of an external compressed air cylinder. Then, personnel can start the detection. The compressed air cylinder conveys some air with a certain pressure to the connecting pipe 901. The conveyed pressurized air is detected by the second pressure sensor 902 and fed back to the display controller 12 for display, so as to be compared and analyzed with the detection data of the first pressure sensor 11. At the same time, the water pump 1004 is started, and the water in the water tank 1003 is conveyed to the water tank 2 through the water supply pipe 1008. At this time, water will slowly appear in the water tank 2 and the water level will gradually rise until the pipe body 4 is completely submerged in water, then the water pump 1004 can be stopped. The compressed air is conveyed to the pipe body 4 through the connecting pipe 901 and the spring conveying pipe 903. The first pressure sensor 11 detects an increase in the pressure inside the pipe body 4. At this time, if there are damages such as cracks and perforations in the pipe body 4, the gas with a higher pressure inside the pipe body 4 will flow out from these damaged parts, generating dense bubbles in the water. And by comparing the detection data of the first pressure sensor 11 with that of the second pressure sensor 902, it will be found that the pressure value detected by the first pressure sensor 11 is lower than the pressure value of qualified products. Moreover, personnel can judge the quantity and size of the damaged parts based on the magnitude of this difference. After the detection is completed, the electromagnetic valve 1006 automatically opens, and the water in the water tank 2 will return to the water tank 1003 again through the water pipe 1005;

[0027] The wiring diagrams of the cylinder 5, the first pressure sensor 11, the second pressure sensor 902, the water pump 1004, the electromagnetic valve 1006 and the display controller 12 in the present utility model belong to the common knowledge in the field. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the cylinder 5, the first pressure sensor 11, the second pressure sensor 902, the water pump 1004, the electromagnetic valve 1006 and the display controller 12 will not be explained in detail. In summary, the problems raised in the above background are solved.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
