[0002] Rubber joints, as an important pipe connection component, are widely used in various industrial pipeline systems, building water supply and drainage systems, and HVAC systems. Their main function is to compensate for dimensional changes in pipelines caused by factors such as thermal expansion and contraction, vibration, and displacement, while absorbing equipment vibration, reducing noise transmission, and ensuring the safe and stable operation of the pipeline system.

[0003] In practical applications, the performance of rubber joints is directly related to the reliability and safety of the entire pipeline system. If the performance of rubber joints is substandard, problems such as leakage and rupture may occur, which may not only cause the pipeline system to malfunction, but also lead to safety accidents, resulting in serious economic losses and casualties. Therefore, it is essential to conduct comprehensive and accurate testing of the performance of rubber joints.

[0004] Currently, existing rubber joint performance testing systems have many shortcomings. The testing functions of existing testing systems are relatively limited, often only able to test one aspect of the rubber joint's performance, such as its sealing performance or pressure resistance. This makes it impossible to comprehensively evaluate the overall performance of the rubber joint, resulting in inaccurate test results and failing to provide a reliable basis for the quality assessment of rubber joints.

[0005] To address these issues, we propose a rubber joint performance testing system. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A rubber joint performance testing system includes a support plate 1. An installation groove is formed in the middle of the top surface of the support plate 1 to facilitate the installation of a hydraulic rod 11. A cover plate 2 is bolted to the upper part of the installation groove on the top surface of the support plate 1. The cover plate 2 can be opened to check whether the hydraulic rod 11 is securely installed and can function properly. Maintenance or repair of the hydraulic rod 11 is also convenient. The cover plate 2 is then closed and secured with bolts. A support seat 4 is welded to the left side of the top surface of the support plate 1. A movable plate 9 is slidably connected to the right side of the top surface of the support plate 1. A first test joint 3 and a second test joint 8 are fixedly installed on the sides of the support seat 4 and the movable plate 9 that are close to each other. Flanges are installed on the sides of the first test joint 3 and the second test joint 8 that are close to each other. A rubber joint body 12 can be randomly selected and bolted onto the flanges on the sides of the first test joint 3 and the second test joint 8 that are close to each other.

[0024] Start the air pump 5. The gas generated by the air pump 5 enters the hollow interior of the first test connector 3 through the air pipe 6. Since the air pipe 6 is equipped with a valve, the valve on the air pipe 6 can be closed or opened according to the test requirements, thereby controlling the gas entering the first test connector 3. The gas enters the rubber connector body 12 from the first test connector 3, and then enters the second test connector 8. At this time, observe the pressure gauge 7 installed on the upper part of the second test connector 8 and record the initial value of the pressure. This can achieve the purpose of testing the airtightness of the rubber connector body 12.

[0025] Start the hydraulic rod 11. The output end of the hydraulic rod 11 pushes the moving block 10 to move in the groove on the right side of the top surface of the support plate 1. The moving block 10 drives the moving plate 9 to move along the two sliding grooves on the right side of the top surface of the support plate 1. Since the vertical cross section of the sliding groove is T-shaped, the slider can slide stably in the sliding groove, so that the movement of the moving plate 9 is smooth. By extending and retracting the hydraulic rod 11, the distance between the first test joint 3 and the second test joint 8 can be adjusted, and the working condition of the rubber joint body 12 under different tensile or compressive states can be monitored.

[0026] During the test, continuously observe the changes in the reading of the pressure gauge 7 to check for leaks in the rubber joint body 12. If the reading of the pressure gauge 7 remains stable within a certain period of time, it indicates that the sealing performance of the rubber joint body 12 is good. If the reading continues to drop, it indicates that there is a leak in the rubber joint body 12. At the same time, according to the test requirements, the output pressure of the air pump 5 can be gradually increased to test the pressure resistance of the rubber joint body 12 and record the maximum pressure value that the rubber joint body 12 can withstand.

[0027] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment is used for the airtightness test of the rubber joint body 12 under tension or compression. After the installation of the rubber joint body 12 is completed, the connection of the hydraulic rod 11 and each component is checked to ensure that the system is running normally.

[0028] Start the air pump 5 to allow gas to enter the first test connector 3 and the second test connector 8, and monitor the air pressure through the air pressure gauge 7. Then, start the hydraulic rod 11 to make the moving plate 9 drive the second test connector 8 to reciprocate, simulating the stretching or compression of the rubber joint in actual use. By controlling the movement frequency and stroke of the hydraulic rod 11, the tensile and compressive strength and amplitude of the rubber joint body 12 can be adjusted.

[0029] During the tensile and extrusion test, closely observe the appearance changes of the rubber joint body 12 to check for cracks, deformation, or other issues. At the same time, record the reading of the air pressure gauge 7 regularly to observe for any abnormal fluctuations in air pressure. After a certain period of tensile and extrusion airtightness test, stop the operation of the hydraulic rod 11 and the air pump 5, and check the performance of the rubber joint body 12. If the rubber joint body 12 does not show obvious damage and the air pressure remains stable, it indicates that the rubber joint body 12 has good fatigue resistance. Otherwise, it indicates that its fatigue resistance is poor.

[0030] Implementation effect: When the air pump 5 is started, the generated gas enters the hollow interior of the first test connector 3 through the air pipe 6. The gas enters the rubber connector body 12 from the first test connector 3 and then enters the second test connector 8. At this time, observe the pressure gauge 7 installed on the upper part of the second test connector 8 and record the initial value of the air pressure. This can achieve the purpose of testing the air tightness of the rubber connector body 12. When the hydraulic rod 11 is started, its output end can drive the moving plate 9 to move along the two sliding grooves on the right side of the top surface of the support plate 1 through the moving block 10. By extending and retracting the hydraulic rod 11, the distance between the first test connector 3 and the second test connector 8 can be adjusted. This can test the working condition of the rubber connector body 12 under different tensile or compressive states. At the same time, it can also test the extension and compression of the rubber connector body 12 through the hydraulic rod 11, and achieve the purpose of testing the air tightness of the rubber connector body 12 under tension and compression through the air pump 5.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
