Description

Technical Field

[0001] This application relates to a device for detecting the performance of hydrogen energy valve bodies using intelligent sensors, specifically a hydrogen energy valve body performance detection device. Background Technology

[0002] Hydrogen valves are core components controlling hydrogen flow in the hydrogen energy industry chain. They are specifically designed for the three major stages of hydrogen production, storage, transportation, and application, employing technologies from multiple fields including engineering mechanics, materials science, fluid mechanics, and intelligent control. They are available in various actuation methods, including electric, pneumatic, and hydraulic. Hydrogen valves typically consist of a valve body, valve disc, valve seat, actuator, and connecting parts. After production, hydrogen valves require airtightness testing, often aided by pressure sensors or leakage sensors. Therefore, valve body sealing testing devices are frequently used to perform airtightness testing on hydrogen valves.

[0003] For example, patent CN222166479U discloses a device for testing the air tightness of a regulating valve. This device includes a testing platform, a connecting frame, and a first guide rail. The upper sides of both the left and right sides of the testing platform are connected to the connecting frame, and the lower inner side of the connecting frame is connected to the first guide rail. During testing, the sliding frame rotates to connect the connecting pipe to the regulating valve, which in turn drives the regulating valve to rotate. Then, the air pump is started, and the pressure gauge readings are compared for testing. When the pressure gauge readings change, it indicates that there is a possibility of gas leakage in the regulating valve. This device allows the regulating valve to be rotated, making it convenient to test the air tightness of the regulating valve at different installation angles, thus improving the air tightness testing effect of the regulating valve.

[0004] In the aforementioned patent, during the testing of the regulating valve, the device requires placing the regulating valve between two sets of connecting pipes. To ensure a tight seal during testing, a sealing gasket is often installed between the connecting pipe and the valve port of the test valve to guarantee testing accuracy. However, after prolonged use, the sealing gasket may age and deform, resulting in irregular bumps, cracks, or slight changes in its overall size. This can create gaps of varying sizes between the connecting pipe and the valve port of the regulating valve, potentially causing air leakage during testing and affecting the accuracy of the test. Therefore, it is necessary to provide a hydrogen energy valve body performance testing device with a quickly replaceable gasket to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] Example 1: This example specifically illustrates the basic structure and working principle of a hydrogen energy valve body performance testing device. It belongs to the category of devices that use intelligent sensors to test the performance of hydrogen energy valve bodies. Specifically:

[0040] like Figures 2-3 As shown, this application provides a hydrogen energy valve body performance testing device, including a testing component 1. The testing component 1 is installed in the hydrogen energy valve production workshop and is used to perform airtightness testing on the hydrogen energy valve after production, so as to detect whether the valve body has leakage.

[0041] The test assembly 1 includes a water tank 11, which is fixedly installed on the ground for conducting a sealing test on the hydrogen valve to be tested. A connecting frame 12 is provided on the top of the water tank 11, and a first crossbar 13 is installed at the bottom of the connecting frame 12. A clamping assembly 2 is provided on the first crossbar 13 for fixing the hydrogen valve to be tested.

[0042] In addition, a mounting plate 14 is provided behind the water tank 11. A lead screw 15 is rotatably mounted on the mounting plate 14. At the same time, a first motor (not shown in the figure) is fixedly mounted below the mounting plate 14. The output end of the first motor is fixedly connected to the lead screw 15 and is adapted to drive the lead screw 15 to rotate. The connecting frame 12 is slidably mounted on the mounting plate 14, and the back side of the connecting frame 12 is threadedly connected to the lead screw 15. Thus, the rotation of the first motor can drive the connecting frame 12 to move, so that the clamping assembly 2 can enter or move away from the water tank 11.

[0043] Meanwhile, a light fixture 16 is also provided on the top side of the mounting plate 14. The light fixture 16 is positioned so that the staff can better judge the seepage of bubbles during testing.

[0044] like Figure 3 As shown, the clamping assembly 2 includes a fixing plate 21, which is fixedly installed on the top of the first crossbar 13. A placement box 22 is fixedly disposed at the center of the fixing plate 21. The placement box 22 is used to place the hydrogen valve to be tested, and a temperature sensor (not shown in the figure) is installed at a suitable position inside the placement box 22 to monitor the ambient temperature inside the placement box 22 in real time, so as to record the possible impact of temperature data on the performance of the hydrogen valve during the test.

[0045] Meanwhile, two sets of first cylinders 23 are fixedly installed on both sides of the placement box 22. A placement frame 231 is fixedly installed on the output end of the first cylinder 23. One side of the placement frame 231 passes through the placement box 22 and a push plate 24 is fixedly installed. At the same time, a through air hole 241 is provided in the center of the push plate 24. The side of the air hole 241 away from the push plate 24 is connected to an external air supply device (not shown in the figure) for supplying air into the hydrogen valve to be tested. A pressure sensor (not shown in the figure) is also provided on the pipeline connecting the air hole 241 and the external air supply device to accurately monitor the air pressure supplied to the hydrogen valve and ensure that the supplied air pressure reaches the set value, thereby accurately testing the air tightness of the hydrogen valve under different pressures.

[0046] When the test begins, the hydrogen valve to be tested is first placed in the placement box 22, and sealing gaskets are placed on both sides of the hydrogen valve. Then, the two sets of first cylinders 23 are started, so that the push plate 24 moves to both sides of the hydrogen valve and clamps it. At this time, the air hole 241 is aligned with the air inlet of the hydrogen valve. The external air supply device delivers air at a set pressure into the hydrogen valve through the air hole 241. The pressure sensor on the pipeline monitors the air pressure in real time to ensure that the pressure is stable at the set value. At the same time, the first motor is started, driving the lead screw 15 to rotate, so that the connecting frame 12 slides down along the mounting plate 14 until the clamping assembly 2 carrying the hydrogen valve is completely immersed in the water in the water tank 11.

[0047] Meanwhile, staff observed whether bubbles were generated around the hydrogen valve in the water tank 11. If there were continuous bubbles, it indicated that the hydrogen valve was not airtight. If no bubbles were generated or only a small amount of instantaneous bubbles were generated, it was deemed to be qualified. Throughout the test, the lamp 16 provided sufficient light to facilitate staff to clearly observe the bubble situation.

[0048] After the test is completed, the clamping assembly 2 is raised above the water surface, the first cylinder 23 is released, and the push plate 24 is moved away from the hydrogen valve. At this time, the hydrogen valve can be quickly replaced.

[0049] Example 2: Since the placement of sealing gaskets on both sides of the hydrogen valve often requires manual installation, testing efficiency is reduced. Furthermore, the gaskets wear down over time, creating gaps of varying sizes between the connecting pipe and the regulating valve port. This can lead to air leakage during testing. Therefore, improvements are made to the connecting bracket 12, specifically:

[0050] like Figure 2 , Figures 4-6As shown, a second crossbar 17 is also provided on the connecting frame 12. A material changing assembly 3 is installed on the second crossbar 17. The material changing assembly 3 includes a second cylinder 31, which is fixedly installed on the top of the second crossbar 17. At the same time, a connecting plate 32 is fixedly installed on the output end of the second cylinder 31. The connecting plate 32 is adapted to move on the second crossbar 17.

[0051] Meanwhile, a storage box 33 is fixedly installed at the bottom of the connecting plate 32. A storage rack 34 is installed on one side of the storage box 33. Multiple sets of sealing gaskets are arranged inside the storage rack 34. The inner diameter of the sealing gasket is slightly smaller than the diameter of the hydrogen valve connection port. The storage rack 34 includes two sets of first insert rods 341 rotatably installed on the outside of the storage box 33. At the same time, two sets of second motors (not shown in the figure) are set inside the storage box 33. The output end of the second motor is fixedly connected to the first insert rod 341. Meanwhile, a stop block 342 is sleeved on the outside of the first insert rod 341. After rotation, the stop block 342 is suitable for contacting the side of the sealing gasket, so that the gasket will not easily detach from the storage rack 34.

[0052] Meanwhile, two sets of second insert rods 343 are provided below the first insert rod 341. The second insert rods 343 are used to support the bottom of the sealing gasket. A baffle 344 is fixedly installed on the outside of the second insert rods 343. The baffle 344 is used to prevent the sealing gasket from slipping off the second insert rods 343. There is a certain gap between the baffle 344 and the stop block 342. This gap is used to facilitate the removal of the outermost sealing gasket.

[0053] Meanwhile, in order to keep the sealing gaskets neatly arranged, a third cylinder 35 is provided at the bottom of the storage box 33. A push block 36 is fixedly installed at the output end of the third cylinder 35. The size of the push block 36 is larger than the size of the sealing gasket, and the push block 36 passes through the storage box 33 and contacts the sealing gasket, so that multiple sets of sealing gaskets are neatly arranged inside the storage rack 34.

[0054] like Figure 6 As shown, a feeding section 4 is also provided at the bottom of the storage box 33. The feeding section 4 includes a third motor 41. A turntable 42 is fixedly installed on the output end of the third motor 41. Three sets of connecting arms 43 extend outward from the turntable 42, and suction cups 44 are fixedly installed at the ends of the connecting arms 43. The suction cups 44 are adapted to rotate together under the drive of the turntable 42. At the same time, an air pump 45 is fixedly installed on the top of the turntable 42. The air pump 45 is adapted to be connected to multiple sets of suction cups 44 to control the suction and desorption of the suction cups 44.

[0055] Before testing, the second cylinder 31 moves the storage box 33 toward the clamping assembly 2. When it reaches the working position, the third motor 41 starts and drives the turntable 42 to rotate, causing the connecting arm 43 with the suction cup 44 to rotate to the storage rack 34. At this time, the air pump 45 works to make the suction cup 44 generate suction, which picks up the outermost sealing gasket of the storage rack 34. Then the turntable 42 continues to rotate, rotating the connecting arm 43 with the sealing gasket to the front of the push plate 24 of the clamping assembly 2. Then the air pump 45 works again and releases the air from the suction cup 44, placing the sealing gasket between the push plate 24 and the hydrogen valve, thus completing the installation of the sealing gasket.

[0056] like Figures 7-8 As shown, a recycling component 5 is also provided at the bottom of the storage box 33. The recycling component 5 includes a receiving cavity 51. Two sets of slide rails 52 are provided at the bottom of the receiving cavity 51. A slider 53 is slidably installed on the top of the slide rails 52. At the same time, a recycling box 54 is fixedly installed on the top of the slider 53. The recycling box 54 is used to recycle the sealing ring after the test. A fourth cylinder 55 is also fixedly installed inside the receiving cavity 51. The output end of the fourth cylinder 55 is fixedly connected to the recycling box 54 and is suitable for driving the recycling box 54 to extend outward.

[0057] After the test, the push plate 24 and the hydrogen valve will gradually move away from each other. At this time, the turntable 42 will drive the suction cup 44 to reach between the push plate 24 and the hydrogen valve again, and under the drive of the air pump 45, it will re-adsorb the used sealing gasket. Then the turntable 42 will continue to rotate. When it reaches the position between the storage rack 34 and the recycling component 5, the turntable 42 will stop rotating. Then the recycling box 54 will be pushed outward under the drive of the fourth cylinder 55. At this time, the air pump 45 controls the suction cup 44 to release air, so that the used sealing gasket falls into the recycling box 54, completing the recycling of the sealing gasket.

[0058] In summary, the automatic recycling of the sealing gaskets after use is achieved by setting up the recycling component 5, avoiding the tedious manual recycling and providing convenience for the subsequent processing of the sealing gaskets. Furthermore, the recycling component 5, together with the material replacement component 3, forms a complete sealing gasket replacement and recycling system, further improving the automation level and practicality of the hydrogen energy valve body performance testing device.

[0059] Example 3: Because the sealing gasket may not be positioned accurately between the push plate 24 and the hydrogen valve, it affects subsequent testing. Also, at the end of the test, the sealing gasket may adhere to one side of the push plate 24 and the hydrogen valve, which will affect subsequent removal. Therefore, improvements are made to the push plate 24, specifically:

[0060] like Figures 9-10As shown, a hook assembly 6 is provided on the outside of the push plate 24. The hook assembly 6 is used for the accurate positioning of the sealing gasket. The hook assembly 6 includes a fifth cylinder 61, which is fixedly installed on the top of the placement frame 231. At the same time, a through slot is provided at the center of the push plate 24. A top block 62 is slidably installed inside the slot. The size of the top block 62 is adapted to the inner ring size of the sealing gasket and is suitable for passing through the inner ring of the sealing gasket.

[0061] When the sealing gasket reaches the space between the push plate 24 and the hydrogen valve under the action of the feeding section 4, the top block 62 will extend outward under the action of the fifth cylinder 61 and pass through the inner ring of the sealing gasket, so that the sealing gasket is lifted by the top block 62. When the push plate 24 gradually approaches the hydrogen valve, the top block 62 will retract into the groove at the same time. At this time, the sealing gasket is just clamped between the push plate 24 and the hydrogen valve, and the position is accurate, effectively avoiding test errors caused by position deviation.

[0062] In order to prevent the sealing gasket from sticking to the push plate 24 or the hydrogen valve after the test, multiple sets of bosses 63 are provided on the outer side of the top block 62 near the push plate 24. The bosses 63 are used to push the sealing gasket out of the push plate 24, and the sealing gasket will seal the gap between the top block 62 and the push plate 24 during the test to ensure the quality of the test.

[0063] Meanwhile, multiple sets of electrically operated push rods 64 are also installed at the top of the top block 62. In the initial state, the push rods 64 retract into the interior of the top block 62. When it is necessary to recycle the sealing gasket, since the inner diameter of the sealing gasket is smaller than the diameter of the hydrogen valve connection port, the push rods 64 extend outward and come into contact with the sealing gasket. Then, driven by the fifth cylinder 61, the sealing gasket is pulled out. At this time, whether the sealing gasket is attached to the push plate 24 or the hydrogen valve, it will be successfully separated and pulled out by the joint action of the boss 63 and the push rods 64, ensuring the smooth progress of the recycling process. This not only improves the accuracy of the test, but also simplifies the cleaning work after the test and improves the overall testing efficiency.

[0064] In summary, the hydrogen valve body performance testing device provided in this application, by setting the hanging component 6, achieves accurate positioning of the sealing gasket between the push plate 24 and the hydrogen valve, effectively avoiding test errors caused by position deviation and improving the accuracy of the test.

[0065] Meanwhile, the boss 63 and the push rod 64 in the mounting assembly 6 enable the sealing gasket to be easily separated from the push plate 24 or the hydrogen valve after the test, simplifying the cleaning work after the test and further improving the overall testing efficiency.

Various modifications and variations can be made to this application by those skilled in the art.
