Description

Technical Field

[0001] This utility model relates to the technical field of valve testing devices, and in particular to an industrial valve hot-cold alternating test device. Background Technology

[0002] Thermal cycling test chambers are essential testing equipment for ensuring the stable operation of products under various environments. They are particularly suitable for components that need to operate under extreme temperature variations, such as those in the automotive, aerospace, and electronics industries. The thermal cycling test chamber for industrial valves you mentioned can also perform performance tests in similar environments, ensuring that valves can still function normally under extreme conditions of alternating hot and cold temperatures. This prevents equipment failure due to drastic temperature changes. As a core component of industrial equipment, the temperature resistance of valves is especially important, particularly in high- and low-temperature environments such as those in the chemical, petroleum, and natural gas industries. Therefore, thermal cycling test chambers can simulate these temperature changes, verify the stability of valves under extreme temperature differences, and ensure their reliability in practical applications.

[0003] In existing technologies, the placement box and temperature zone isolation structure of conventional devices use a gap fit. This allows for easy convection between the hot and cold media in the high-temperature and low-temperature zones, causing heat to diffuse from the high-temperature zone to the low-temperature zone. To maintain the target temperature, additional energy is required, significantly increasing energy consumption. Utility Model Content

[0009] With the above technical solution, when the drive motor is started, its output end drives the motor rotating rod to rotate, causing the limiting gear fixed on the outer wall to rotate synchronously.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, when the drive motor is started, its output end drives the motor rotating rod to rotate, causing the limiting gear fixed on the outer wall to rotate synchronously. The limiting gear meshes with the drive rack, causing the drive rack to rotate, which in turn drives the second limiting gear to rotate. The rotating rod fixed on the inner wall of the second limiting gear rotates with it, causing the drive gear on the outer wall to rotate synchronously. The drive gear meshes with the driven gear, causing the threaded rod on the inner wall of the driven gear to rotate on the inner wall of the drive device housing, the isolation plate, and the test device body. Since the threaded rod is threadedly connected to the connecting plate, the connecting plate causes the product placement box to slide up and down along the outer wall of the isolation plate, realizing the position adjustment of the product placement box. At the same time, the second limiting gear meshes with the driven rack, thereby causing the driven rack to rotate, driving the third limiting gear meshing with it to rotate. The rotating rod fixed on the inner wall of the third limiting gear rotates with it, causing the second drive gear on the outer wall to rotate synchronously. The second drive gear meshes with the second driven gear, causing the threaded rod on the inner wall of the second driven gear to rotate on the inner wall of the drive device housing, the test device body, and the isolation plate. Because the threaded rod two is threadedly connected to the connecting plate two, the connecting plate two drives the product placement box two to slide along the inner wall of the isolation plate, realizing the staggered vertical position adjustment of the product placement box two and the product placement box. Thus, through the above transmission, the product placement box and product placement box two can synchronously complete position adjustment, meeting the spatial adjustment requirements of the alternating hot and cold test. At the same time, the top and bottom of the product placement box and product placement box two will be in contact with the surface of the isolation plate, effectively blocking heat exchange between the high-temperature and low-temperature areas inside the test device, thereby playing a certain sealing role and preventing a large amount of heat and cold air loss from inside the test device, saving experimental costs.

[0017] This invention utilizes an adjusting groove to rotate the worm gear, which in turn drives the worm wheel to rotate on the inner wall of the support base. Two guide grooves at the top of the worm wheel are slidably connected to two guide rods. As the worm wheel rotates, the guide rods cause the clamping slider at the top to slide along the guide grooves. The T-shaped limiting groove at the bottom of the clamping slider slides along the T-shaped limiting block at the top of the support base, ensuring stable movement. Thus, through this transmission, the two clamping sliders can move in opposite directions, completing the clamping or releasing action of the industrial valve. This avoids valve displacement due to force and is compatible with valves of different diameters, eliminating the need for repeated clamp changes and improving the flexibility and applicability of the equipment.

A worm gear 302 is rotatably connected to the inner wall of the support base 301. A worm 303 is meshed with the outer wall of the worm gear 302.

[0036] The outer wall of the worm gear 303 is rotatably connected to the inner wall of the support base 301.

[0037] A guide rod 306 is slidably connected to the inner wall of the guide groove 305. A clamping slider 307 is fixedly connected to the top of the guide rod 306.

[0038] There are two guide grooves 305, two guide rods 306, two clamping sliders 307, and two T-shaped limit blocks 309.

[0039] The implementation principle of the industrial valve thermal cycling test device in this embodiment is as follows: The worm gear 303 is rotated by adjusting the groove 304, which drives the worm wheel 302 to rotate on the inner wall of the support base 301. Two guide grooves 305 at the top of the worm wheel 302 are slidably connected to two guide rods 306. When the worm wheel 302 rotates, the guide rods 306 drive the clamping slider 307 at the top to slide along the guide grooves 305. The T-shaped limiting groove 308 at the bottom of the clamping slider 307 slides along the T-shaped limiting block 309 at the top of the support base 301, ensuring stable movement. Thus, through the above transmission, the two clamping sliders 307 can move in opposite directions, completing the clamping or releasing action of the industrial valve. This avoids valve force deviation and is suitable for valves of different diameters, eliminating the need for repeated clamp replacements, thus improving the flexibility and applicability of the equipment. Then, by starting the drive motor 202, its output end drives the motor rotating rod 203 to rotate, causing the limiting gear 204 fixed on the outer wall to rotate synchronously. The limiting gear 204 meshes with the drive rack 205, causing the drive rack 205 to rotate, which in turn drives the second limiting gear 206 to rotate. The rotating rod 207 fixed to the inner wall of the second limiting gear 206 rotates with it, causing the drive gear 208 on the outer wall to rotate synchronously. The drive gear 208 meshes with the driven gear 209, causing the threaded rod 210 on the inner wall of the driven gear 209 to rotate within the drive device housing 201, the isolation plate 213, and the test device body 1. Since the threaded rod 210 is threadedly connected to the connecting plate 211, the connecting plate 211 causes the product placement box 212 to slide up and down along the outer wall of the isolation plate 213, achieving position adjustment of the product placement box 212. Simultaneously, the second limiting gear 206 meshes with the driven rack 214, thereby causing the driven rack 214 to rotate, which in turn drives the third limiting gear 215 meshing with it to rotate. The rotating rod 216, fixed to the inner wall of the limiting gear 215, rotates with it, causing the driving gear 217 on the outer wall to rotate synchronously. The driving gear 217 meshes with the driven gear 218, driving the threaded rod 219 on the inner wall of the driven gear 218 to rotate on the inner walls of the drive device housing 201, the test device body 1, and the isolation plate 213. Since the threaded rod 219 is threadedly connected to the connecting plate 220, the connecting plate 220 drives the product placement box 221 to slide along the inner wall of the isolation plate 213, realizing the staggered vertical position adjustment of the product placement box 221 and the product placement box 212. Thus, through the aforementioned transmission, the product placement box 212 and the second product placement box 221 can be adjusted in position synchronously to meet the spatial adjustment requirements of the alternating hot and cold test. At the same time, the top and bottom of the product placement box 212 and the second product placement box 221 will be attached to the surface of the isolation plate 213, effectively blocking the heat exchange between the high temperature zone and the low temperature zone inside the test device body 1, thereby playing a certain sealing role, preventing a large amount of heat and cold air from being lost inside the test device body 1, and saving experimental costs.
