The main purpose of this step is to comprehensively ensure the pipeline's tightness and overall installation quality, laying a solid foundation for subsequent safe and stable operation. During the pressure test, water or gas at a certain pressure is injected into the pipeline to check for potential problems such as leaks, deformation, or insufficient strength.

[0003] Existing pipeline pressure testing devices often use bolts for assembly, which is not suitable for pipelines of different sizes and lengths. Assembly requires alignment with the center of the pipeline, making the operation cumbersome. The pipeline installation is not precise enough, making it difficult to quickly assemble and pressure test. For example, Chinese Patent Publication No. CN221527925U discloses a pipeline pressure testing mechanism that is easy to assemble, including a frame, a pressure testing pump, an adjustment component, two fixing plates, an inlet pipe, a pressure gauge, and an outlet pipe.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6This utility model provides an easy-to-assemble pipe pressure testing mechanism, including a frame 4, an inner cylinder 3 at the top center of the frame 4, a mounting assembly 2 at the bottom of the inner cylinder 3, and a calibration assembly 1 on the inner cylinder 3 for calibrating and positioning pipe fittings of different diameters. A first support plate 6 and a first sealing plate 9 are located at the top of the frame 4 and at both ends of the frame 4. A hydraulic push rod 5 is fixed to the side of the first support plate 6 near the inner cylinder 3, and a second sealing plate 14 is fixed to the output end of the hydraulic push rod 5. A water outlet 12 is opened through the center of the side of the first sealing plate 9, and a water inlet pipe 11 connected to the water outlet 12 is internally threaded. In use, the test pipe fitting to be pressure tested is inserted into the inner cylinder 3, and the calibration assembly 1 calibrates the pipe fitting, thereby achieving centered positioning of the test pipe fitting and making it suitable for pipes of different diameters. The positioning eliminates the need for manual adjustment, effectively improving the overall efficiency of pressure testing. The inner cylinder 3 and calibration component 1 can be removed from the top of the frame 4 via the assembly component 2, and other components on the top of the frame 4 can be disassembled into individual parts, reducing the overall volume and facilitating transfer and storage. Simultaneously, the individual modules are easy to assemble and can be quickly assembled into a whole, effectively improving overall usability. After the pipe is centered and aligned, the hydraulic push rod 5 is activated. The output end of the hydraulic push rod 5 drives the second sealing plate 14 to move the pipe closer to the first sealing plate 9, thereby sealing the pipe's port through the second sealing plate 14 and the first sealing plate 9. The inlet pipe 11 is connected to an external pressure testing pump, which delivers the pressure testing water through the outlet 12 to the inside of the pipe, creating hydraulic pressure inside the pipe. This allows for the detection of cracks and leaks in the sidewalls of the pipe, performing a pressure test on the pipe.

[0027] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that the calibration assembly 1 includes a push rod 104 that slides through the side wall of the inner cylinder 3. Multiple push rods 104 are arranged in a ring. One end of the push rod 104 located outside the inner cylinder 3 has an arc-shaped end 105. A spinning sleeve 101 is threaded onto the outer wall of the inner cylinder 3. The end of the spinning sleeve 101 has a tapered inclined surface 102 that slides with the arc-shaped end 105. In operation, the pipe to be tested is inserted into the inner cylinder 3, and the spinning sleeve 101 is rotated to achieve the desired spinning effect. The sleeve 101 moves relative to the inner cylinder 3, thereby cooperating with the conical inclined surface 102 and the arc end 105 to press multiple push rods 104 synchronously. This allows the ends of the multiple push rods 104 to uniformly squeeze the outer wall of the pipe inserted inside the inner cylinder 3. The multiple push rods 104 push the pipe to automatically center and position it, so that the central axis of the pipe is aligned with the central axis of the inner cylinder 3. This method is applicable to the centering and positioning of pipes of different diameters, eliminating the need for manual adjustment and effectively improving the overall efficiency of pressure testing.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the assembly component 2 includes a slot 202 opened on the top of the frame 4, a T-shaped bottom block 201 that slides and adapts to the slot 202 is fixed on the bottom of the inner cylinder 3, and a second support plate 13 is fixed on the bottom of the first sealing plate 9. The bottom ends of the first support plate 6 and the second support plate 13 are both threaded with connecting bolts 7. When not in use, by pushing the T-shaped bottom block 201 out of the slot 202, the inner cylinder 3 and the calibration component 1 can be removed from the top of the frame 4. By removing the connecting bolts 7 on the bottom ends of the first support plate 6 and the second support plate 13, the components on the top of the frame 4 can be disassembled one by one and divided into various parts, thereby reducing the overall volume and facilitating transfer and storage. At the same time, the individual modules are easy to assemble and can be quickly assembled into a whole for use, effectively improving the overall ease of use.

[0029] Further as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it is worth noting that rubber plates 8 are attached and fixed to the sides of the second sealing plate 14 and the first sealing plate 9 that are close to each other. In actual operation, when the second sealing plate 14 and the first sealing plate 9 squeeze the two ends of the pipe, the rubber plates 8 will undergo elastic deformation, thereby sealing the ends of the pipe through the rubber plates 8.

[0030] This solution includes the following working process: The pipe fitting to be tested is inserted into the inner cylinder 3. By rotating the spinning sleeve 101, the spinning sleeve 101 moves relative to the inner cylinder 3. This, in turn, is achieved by the conical inclined surface 102 and the arc end 105 pressing multiple push rods 104 synchronously. This allows the ends of the multiple push rods 104 to uniformly compress the outer wall of the pipe fitting inserted into the inner cylinder 3. The multiple push rods 104 then push the pipe fitting to automatically center and position it, aligning the pipe fitting's central axis with the central axis of the inner cylinder 3. This method is applicable to centering pipes of different diameters. After the pipe fitting is centered and aligned, the hydraulic push rod 5 is activated. The output end of the hydraulic push rod 5 drives the second sealing plate 14 to push the pipe fitting towards... The pipe is moved closer to the first sealing plate 9, thereby sealing the pipe port through the second sealing plate 14 and the first sealing plate 9. The test water flow is delivered to the inside of the pipe through the water inlet pipe 11 and the water outlet 12, thereby making the inside of the pipe hydraulic and performing pressure testing on the pipe. When not in use, the inner cylinder 3 and the calibration component 1 can be removed from the top of the frame 4 by pushing the T-shaped bottom block 201 out of the slot 202. The components on the top of the frame 4 can be removed one by one by removing the connecting bolts 7 on the bottom of the first support plate 6 and the second support plate 13, thereby reducing the overall volume and facilitating transfer and storage. At the same time, the individual modules are easy to assemble and can be quickly assembled into a whole for use.

[0031] Further as Figure 3 and Figure 4 As shown, it is worth noting that a ball bearing 106 is rolled on one end of the push rod 104 located inside the inner cylinder 3. During operation, the ball bearing 106 effectively reduces the friction between the end of the push rod 104 and the outer wall of the pipe, improves the smoothness of the pipe centering and correction, and greatly reduces the squeezing damage to the pipe.

[0032] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that a pressure gauge 10 is installed on the water inlet pipe 11, and a rubber sleeve 103 is attached and fixed to the outer wall of the spinning sleeve 101. In actual operation, the water pressure inside the test pipe is observed through the pressure gauge 10, and a pressure test is conducted on the test pipe. The rubber sleeve 103 increases the friction when the spinning sleeve 101 is turned by hand, making it easier to rotate and adjust the spinning sleeve 101.

[0033] In summary: By inserting the test fitting to be pressure tested into the inner cylinder 3 and calibrating it using the calibration component 1, the test fitting can be centered and positioned. This method is applicable to centered positioning of pipes of different diameters, eliminating the need for manual adjustment and effectively improving the overall efficiency of pressure testing. The inner cylinder 3 and calibration component 1 can be removed from the top of the frame 4 using the assembly component 2, and other components on the top of the frame 4 can be disassembled one by one, reducing the overall volume and facilitating transfer and storage. Furthermore, the modules are easy to assemble and can be quickly assembled into a whole, effectively improving the overall ease of use.

[0034] The hydraulic push rod 5 and pressure gauge 10 can be purchased from the market. The hydraulic push rod 5 and pressure gauge 10 are equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
