Description

Technical Field

[0001] The utility model relates to the field of pipeline testing, and in particular to a rotary pressure testing device for a pipeline component. Background Art

[0002] A multi-channel tube bundle section typically refers to a component consisting of multiple pipes or tube bundles. These pipes or tube bundles are often used to transport fluids, gases, or other media in industrial or engineering applications. Testing the tightness of multi-channel tube welds is critical, especially in the industrial and manufacturing fields, where ensuring that the piping system is leak-free is crucial. Therefore, pressure testing equipment is required to test the produced multi-channel tube bundle sections.

[0003] However, most of the current rotary pressure testing devices for pipeline components have the following problems:

[0004] 1. When testing the existing rotary pressure testing device for pipeline components, the holes and gaps in the welding parts of the pipeline components are easily clogged by impurities, and there are weak points in the welding parts. The holes and gaps are likely to affect the firmness of use during subsequent use, making it inconvenient to handle the holes and gaps in the pipeline components.

[0005] 2. In the existing rotary pressure testing device for pipeline components, when the pipeline components are tested, the pipeline components are mostly placed on a workbench. During the test, most pipeline components do not have a limit function. If offset occurs, it is easy to affect the test effect of the pipeline component, and it is inconvenient to conveniently support and fix the pipeline component.

[0006] Therefore, we have made improvements to this problem and proposed a rotary pressure testing device for pipeline components. Utility Model Content

[0007] The purpose of the utility model is to address the current problems of inconvenience in processing gaps and holes in pipeline components and inconvenience in conveniently supporting and fixing the pipeline components.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] A rotary pressure testing device for pipeline components is provided to improve the above problems.

[0010] The utility model is specifically as follows:

[0011] The present invention comprises a bottom plate, a connecting frame fixedly connected to the bottom plate, a first servo motor fixedly connected to the connecting frame, an output shaft of the first servo motor fixedly connected to a first bevel gear, the first bevel gear meshingly connected to the second bevel gear, a detection housing fixedly connected to the second bevel gear, the detection housing is connected to the connecting frame through a sealed bearing, a fixing plate fixedly connected to the detection housing, a first cover plate is provided on the detection housing, a second cover plate is provided on the detection housing, a first sealing gasket is fixedly connected to the first cover plate and the second cover plate, a connecting bolt is threadedly connected to the first cover plate and the second cover plate, and the detection housing is provided with a plurality of connecting bolts. A material port is installed, a mounting plate is fixedly connected to the first cover plate, a second servo motor is fixedly connected to the mounting plate, an output shaft of the second servo motor is fixedly connected to a third bevel gear, the third bevel gear is meshingly connected to a fourth bevel gear, a threaded rod is fixedly connected to the fourth bevel gear, the threaded rod is rotatably connected in the mounting plate, a connecting plate is threadedly connected to the threaded rod, a fixing frame is fixedly connected to the connecting plate, a support plate is fixedly connected to the fixing frame, a multi-channel pipe assembly is provided on the mounting plate, an isolation sealing frame is fixedly connected to the second cover plate, and an air supply pipe is fixedly connected to the second cover plate and the isolation sealing frame.

[0012] As a preferred technical solution of the present invention, the outer diameter of the detection housing fits the inner diameters of the first cover plate and the second cover plate, and the fixing plates are distributed at equal angles on the detection housing.

[0013] As a preferred technical solution of the present invention, the fourth bevel gears are distributed on the third bevel gear at equal angles, and the fourth bevel gears correspond one-to-one with the connecting plates through threaded rods.

[0014] As a preferred technical solution of the present invention, the threaded rod is fixedly connected to the center of one side of the fourth bevel gear, and the side end surface of the connecting plate is in contact with the inner side surface of the mounting plate.

[0015] As a preferred technical solution of the present invention, the cross section of the support plate is arc-shaped, and the second cover plate is fixedly connected to the center portion of one side of the isolation sealing frame.

[0016] As a preferred technical solution of the present invention, a second sealing gasket is fixedly connected to the isolation sealing frame, an air pressure sensor is installed on the isolation sealing frame, and the inner side surface of the isolation sealing frame is in contact with the outer wall of the multi-channel tube assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the solution of the present utility model:

[0019] 1. A detection shell is provided; when processing the gaps and holes in the weak points, liquid can be added to the detection shell through the material port. The sealed detection shell can prevent liquid leakage, and then the first servo motor on the connecting frame is turned on. When the first servo motor drives the first bevel gear to operate, the first bevel gear can drive the detection shell to rotate through the second bevel gear. When the liquid in the detection shell rotates, it can cause a strong impact on the gaps of the multi-channel pipe assembly under the action of the centrifugal force of the liquid, thereby preventing the weak points or gaps from affecting the use effect. After the holes and gaps are processed, the water can be discharged from the material port, and then the first cover plate on the detection shell can be removed and replaced with the second cover plate. The isolation sealing frame on the second cover plate can support the multi-channel pipe assembly and isolate and seal the multi-channel pipe assembly, and the second sealing gaskets on the isolation sealing frames on both sides can improve the sealing effect. The welded space is inflated through the air pipe. If there is a leak in the holes and gaps, the interlayer can be detected by the air pressure sensor, and the leak can be checked to see where the leak occurs.

[0020] 2. A mounting plate is provided; when the multi-channel tube assembly to be tested needs to be supported and fixed, the mounting plate on the first cover plate can be inserted into the large pipe of the multi-channel tube assembly, and then the second servo motor is turned on to drive the third bevel gear to operate. The third bevel gear can drive the threaded rod to rotate through the fourth bevel gear. When the threaded rod rotates, it can push the connecting plate to move. When the connecting plate moves outward, the connecting plate can support and fix the inner wall of the multi-channel tube assembly through the fixing frame and the support plate, thereby improving the firmness of the multi-channel tube assembly during testing and avoiding deviation affecting the test effect.

[0021] Through a series of carefully designed mechanical actions and structural configurations, the impact of weak spots, gaps, and holes on the performance of the pipe assembly is effectively prevented. First, the design of the detection housing allows liquid to be added through the material port, which is then sealed to form a closed space, ensuring that the liquid cannot leak. When the first servo motor starts and drives the first bevel gear, the detection housing rotates accordingly through the transmission of the second bevel gear. This rotation generates centrifugal force in the liquid within the detection housing, which exerts pressure on the gaps in the pipe assembly, thereby impacting and cleaning the gaps and holes. This dynamic liquid impact not only cleans impurities from the gaps but also verifies the tightness of the gaps and eliminates defects such as cold welds, incompletely sealed weak spots, or gap welds. When the liquid impacts an incompletely sealed weak spot, gap, or hole, it causes flow due to a pressure difference. This pressure difference is detected by the air pressure sensor, allowing the specific leak to be located.

[0022] The air pressure sensor plays a key role in the rotary pressure test device for pipe components, especially when the second cover is used to test the tightness of the pipe components. The following is a description of the design and setup of the air pressure sensor:

[0023] 1. Position design: The air pressure sensor is mounted on an isolation seal frame (22), which is fixedly connected to the second cover plate (21). This design enables the sensor to directly contact the outer wall of the pipe assembly (20), thereby more accurately detecting possible air leaks.

[0024] 2. Function: When the second cover plate (21) replaces the first cover plate (8) and is fixed to the detection housing (6), the second sealing gasket (24) on the isolation sealing frame (22) forms a sealed space. At this time, the welding space of the pipeline assembly is inflated through the air supply pipe (23), and the air pressure sensor (25) can detect slight air pressure changes caused by holes or gaps.

[0025] 3. Working principle: If there are unsealed holes or gaps in the pipe assembly, gas will leak from these defects during the inflation process, causing the air pressure in the sealed space to drop. The air pressure sensor (25) can capture this air pressure change and convert it into an electrical signal.

[0026] 4. Signal processing: After the electrical signal is processed, it can display or record the location and extent of the leak. The operator can repair the pipeline components or conduct further inspections based on this information.

[0027] 5. Installation method: The air pressure sensor (25) is installed on the isolation sealing frame (22) by an appropriate fixing method to ensure that it fits tightly with the outer wall of the pipeline assembly (20) to improve the sensitivity and accuracy of the detection.

[0028] 6. Compatibility design: During the design, it is considered that the air pressure sensor (25) needs to be compatible with the existing mechanical structure, including the connection method with the second cover plate (21), the isolation sealing frame (22) and the air supply pipe (23).

[0029] 7. Maintenance and replacement: In order to facilitate maintenance and replacement, the design of the air pressure sensor (25) should be easy to disassemble and install, while ensuring stability and reliability in long-term use.

[0030] Through the above design, the air pressure sensor plays a vital role in the rotary pressure testing device of the pipeline component, ensuring the efficiency and accuracy of the detection process.

[0031] After discovering a leak, perform the necessary repairs and repeat the above steps. Once the holes and gaps are confirmed, drain the liquid from the test housing through the material port. Then, replace the first cover with the second, using the isolation seal bracket on the second cover to support and isolate the multi-channel tube assembly. The second sealing gasket on the isolation seal bracket further enhances the sealing effect, ensuring that any leaks can be accurately detected during the inflation test.

[0032] This technical solution not only improves the efficiency of handling gaps and holes in pipeline components, but also enhances the accuracy of detection, effectively avoiding potential leakage problems caused by weak points or gaps and holes, thereby ensuring the sealing and reliability of pipeline components and guaranteeing their performance and safety during use.
