Abstract
Description
Technical Field
[0001] This utility model relates to the field of butterfly valve testing technology, and in particular to a butterfly valve testing device. Background Technology
[0002] Butterfly valves, as a common fluid control valve, are widely used in various industrial piping systems. Their sealing performance and shell strength are key indicators for ensuring safe system operation; therefore, rigorous testing is required during production. Existing butterfly valve testing equipment typically suffers from cumbersome testing processes, low automation, and low testing efficiency. For example, during testing, valve body positioning and clamping often rely on manual operation, which is not only inefficient but also prone to inaccurate test results or equipment damage due to improper operation. Furthermore, traditional testing equipment lacks an effective buffering mechanism when applying test pressure, potentially leading to impact damage to the valve body or test components.
[0003] In summary, a butterfly valve testing device is needed to address the shortcomings of existing technologies. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a butterfly valve testing device, aiming to solve the aforementioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a butterfly valve testing device, comprising a body, a pressure boosting testing component mounted on the body, and a transverse conveying mechanism mounted on the body. The transverse conveying mechanism includes a servo drive module, a push-pull frame, a sliding module, an elastic support component, and a blind plate. The movable end of the servo drive module is connected to the push-pull frame, the bottom wall of the push-pull frame is connected to the sliding module, the elastic support component is mounted on the top of the push-pull frame, and the blind plate is connected to the push-pull frame via the elastic support component. The elastic support component supports the blind plate and adapts to the pressure boosting testing component, providing a longitudinally adjustable buffer pressure space. Through the transverse conveying mechanism, automatic positioning and conveying of the blind plate are achieved, significantly improving testing efficiency. The elastic support component provides a longitudinally adjustable buffer space during the pressure boosting test, effectively absorbing pressure shocks and preventing damage to the valve body and blind plate due to rigid contact. The overall structure achieves precise and stable movement through the servo drive module and the sliding module, ensuring test repeatability and accuracy, combining automation and reliability, and is suitable for efficient testing of butterfly valve housings and sealing performance.
[0006] Furthermore, the elastic support assembly includes a limiting cylinder, a support rod, a buffer spring, and a bearing sleeve. The bottom end of the limiting cylinder is connected to the push-pull frame, and the top end of the limiting cylinder is connected to the support rod. The buffer spring and the bearing sleeve are both sleeved on the support rod, and the bearing sleeve is used to adapt to the connection of the blind plate.
[0007] Furthermore, the push-pull frame has a V-shaped structure, and when the V-shaped push-pull frame moves to its foremost position, the blind plate is located directly below the pressure testing assembly.
[0008] Furthermore, the pressure boosting test assembly includes a test mounting base, a valve body, a pressure boosting cylinder, a connector, and a pressure plate. Both the test mounting base and the pressure boosting cylinder are mounted on the machine body, with the pressure boosting cylinder located directly above the test mounting base. The test mounting base is used to fix the valve body. The bottom output end of the pressure boosting cylinder is connected to the pressure plate via the connector. The pressure plate is used to adapt to the pressure boosting cylinder and perform pressure boosting tests on the valve body directly below it.
[0009] Furthermore, the machine body includes a test bench and a test frame, the test frame being mounted on the test bench, the test bench being used to install a test mounting base and a transverse conveying mechanism, and the test frame being used to install a booster cylinder.
[0010] Furthermore, a cylinder is installed on the side of the test stand near the valve body, and a valve stem is provided on one side of the valve body. The end of the valve stem away from the valve body is connected to the piston end of the cylinder.
[0011] The beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting up a transverse conveying mechanism, the automatic transverse positioning of the blind plate is realized, which improves the testing efficiency, reduces manual intervention, and provides a longitudinally adjustable buffer pressure space through the design of the elastic support component, which effectively avoids impact damage to the valve body and blind plate during the pressurization test and extends the service life of the equipment.
[0013] 2. In this utility model, by setting up the pressure boosting test component and the transverse conveying mechanism to work together, the automated process of butterfly valve shell testing and sealing testing is realized, with high testing accuracy and good consistency;
[0014] 3. In this utility model, by setting up a ground servo transmission module and a sliding module in cooperation, the smooth and precise linear movement of the push-pull frame and the blind plate above it is realized, which further improves the reliability of the test. In addition, the push-pull frame adopts a V-shaped structure, which ensures that the blind plate can be accurately moved to the bottom of the pressure test component. The positioning is accurate and has certain application value and promotion value. Attached Figure Description

[0026] like Figures 1-7 As shown, a butterfly valve testing device includes a body 100, a pressure boosting testing component 10 on the body 100, and a transverse conveying mechanism 20 on the body 100. The transverse conveying mechanism 20 includes a servo drive module 21, a push-pull frame 22, a sliding module 23, an elastic support component 24, and a blind plate 25. The movable end of the servo drive module 21 is connected to the push-pull frame 22, the bottom wall of the push-pull frame 22 is connected to the sliding module 23, the elastic support component 24 is installed on the top of the push-pull frame 22, and the blind plate 25 is connected to the push-pull frame 22 through the elastic support component 24. The elastic support component 24 is used to support the blind plate 25 and adapt to the pressure boosting testing component 10 to provide a longitudinally adjustable buffer pressure space.
[0027] In one embodiment, the elastic support assembly 24 includes a limiting cylinder 241, a support rod 242, a buffer spring 243, and a bearing sleeve 244. The bottom end of the limiting cylinder 241 is connected to the push-pull bracket 22, and the top end of the limiting cylinder 241 is connected to the support rod 242. The buffer spring 243 and the bearing sleeve 244 are both sleeved on the support rod 242, and the bearing sleeve 244 is used to adapt and connect the blind plate 25.
[0028] In one embodiment, the push-pull bracket 22 has a V-shaped structure, and when the V-shaped push-pull bracket 22 moves to the frontmost position, the blind plate 25 is located directly below the pressure test assembly 10.
[0029] In one embodiment, the pressure boosting test assembly 10 includes a test mounting base 11, a valve body 12, a pressure boosting cylinder 13, a connector 14, and a pressure plate 15. The test mounting base 11 and the pressure boosting cylinder 13 are both mounted on the body 100, and the pressure boosting cylinder 13 is located directly above the test mounting base 11. The test mounting base 11 is used to fix the valve body 12. The bottom output end of the pressure boosting cylinder 13 is connected to the pressure plate 15 through the connector 14. The pressure plate 15 is used to adapt to the pressure boosting cylinder 13 and perform pressure boosting tests on the valve body 12 directly below it.
[0030] In one embodiment, the machine body 100 includes a test bench 101 and a test rack 102. The test rack 102 is disposed on the test bench 101. The test bench 101 is used to install the test mounting base 11 and the transverse conveying mechanism 20. The test rack 102 is used to install the booster cylinder 13.
[0031] In one embodiment, a cylinder 1011 is installed on the side of the test bench 101 near the valve body 12, and a valve stem 121 is provided on one side of the valve body 12. The end of the valve stem 121 away from the valve body 12 is connected to the piston end of the cylinder 1011.

[0033] The working principle of this utility model is as follows: During testing, the valve body 12 is fixed on the test mounting base 11. The transverse conveyor 20 drives the push-pull frame 22 to move laterally (back and forth) along the sliding module 23 through the servo transmission module 21, pushing the blind plate 25 directly below the pressure boosting test assembly 10. The buffer spring 243 in the elastic support assembly 24 provides buffering force, enabling the blind plate 25 to have longitudinal adjustment capability when under pressure. After the blind plate 25 is in place, the pressure boosting cylinder 13 drives the pressure plate 15 to move downward through the connecting piece 14, applying test pressure to the valve body 12. At the same time, the cylinder 1011 is connected to the valve stem 121 to control the opening or closing of the valve core for housing testing or sealing testing. During housing testing, the valve core is open, and the test medium passes through the valve body 12. During sealing testing, the valve core is closed, and the test medium is isolated. The pressure boosting test assembly 10 provides the required test pressure through the pressure boosting cylinder 13, and the elastic support assembly 24 ensures that the pressure is applied smoothly and avoids hard impacts. The entire testing process is highly automated, easy to operate, and the test results are accurate and reliable.
