Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, it relates to a pressure testing device for valve production and processing. Background Technology

[0002] In existing technologies, when testing valves, existing pressure testing equipment often requires disassembling parts of the structure to operate if the valve needs to be replaced or the testing status needs to be adjusted during the testing process. It lacks a quick clamping and release mechanism, which seriously affects the ability to operate continuously and the connection between processes.

[0003] A more prominent problem is that when it is necessary to temporarily release the valve from its fixed state during the testing process, such as to replace the test piece or perform local maintenance, the existing device is not equipped with a quick unlocking mechanism. The fixed parts are mostly locked with bolts or mechanical clamps, which makes the unlocking process cumbersome, time-consuming, and may even pose a safety hazard if the operation is not performed properly.

[0004] When existing equipment needs to adjust the flow rate of internal water to adapt to different testing requirements (such as low-pressure sealing test and high-pressure strength test), its adjustment mechanism is usually cumbersome and it is difficult to achieve rapid flow rate control. Especially when multiple parameters need to be adjusted in a short time, the response speed and adjustment accuracy of existing equipment are difficult to meet the requirements of efficient testing.

[0032] Please see Figures 1-7A pressure testing device for valve manufacturing and processing includes a support frame 1. A clamping assembly is provided on the support frame 1. The clamping assembly includes a cylinder 2 and a moving plate 3. The cylinder 2 is mounted on the support frame 1, and the moving plate 3 is connected to the output end of the cylinder 2.

[0036] A mounting plate 21 is installed on the fixed sleeve 7, and a tension spring 22 is provided between the mounting plate 21 and the moving ring 8.

[0037] In this embodiment, the valve body 12 is placed at one end of the fixing plate 4, and the connecting block 11 on the connecting pipe 5 is aligned with the connecting groove 13 on the valve body 12. Then, by activating the cylinder 2, the moving plate 3 at the output end is moved to clamp and fix the valve body 12. Next, water is injected into the water tank 14 along the inlet pipe 15. When it is necessary to remove the water, the plug 17 is removed from the drain pipe 16 to discharge the water. Then, by activating the pump body 37, water is sent into the valve along the inlet hose 6. In body 12, pressure gauge 18 is used to test the pressure of valve body 12. After the test, water is sent from outlet hose 10 to water tank 14 by another pump body 37. When the water flows, when it is necessary to adjust the flow rate of the water, rotating ring 9 is rotated along moving ring 8, so that rotating rod 19 and rotating block 20 are rotated to pass through groove 36. Under the action of elastic potential energy of tension spring 22, moving moving ring 8 to the initial position, thereby releasing the fixation of adjusting ring 26.

[0038] Please see Figure 4-5 As an embodiment of a valve production and processing pressure testing equipment for regulating components: A regulating component is provided on the fixed sleeve 7. The regulating component includes a driving gear 23 and a threaded rod 24. The driving gear 23 is rotatably connected to the fixed sleeve 7, and the threaded rod 24 is rotatably connected to the fixed sleeve 7. A driven gear 25 is installed at one end of the threaded rod 24, and the driving gear 23 and the driven gear 25 are meshed and connected.

[0039] An adjusting ring 26 is threadedly connected to the threaded rod 24. A pull rod 27 is slidably connected to the adjusting ring 26. A tension spring 28 is sleeved on one end of the pull rod 27. One end of the tension spring 28 is connected to the adjusting ring 26. A threaded tube 29 is rotatably connected to the fixed sleeve 7. The threaded tube 29 is adapted to the pull rod 27. A threaded seat 30 is installed on the inner side of the threaded tube 29. A screw 31 is installed on the threaded seat 30.

[0040] A guide plate 32 is threadedly connected to the screw 31, and a guide groove 33 is provided on the fixed sleeve 7. The guide plate 32 and the guide groove 33 are slidably connected. A spring plate 34 is provided between the guide plate 32 and the fixed sleeve 7. A connecting ring 35 is installed on the adjusting ring 26. A through groove 36 is provided on the connecting ring 35. The through groove 36 is adapted to the rotating block 20. A pump body 37 is installed on the inlet hose 6 and the outlet hose 10.

[0041] More specifically, after releasing the fixing of the adjusting ring 26, the driving gear 23 is rotated along the fixed sleeve 7. During this rotation, the driven gear 25, which meshes with the driving gear 23, is driven to rotate. This causes the threaded rod 24 on the driven gear 25 to rotate, thereby causing the adjusting ring 26 to slide along the fixed sleeve 7. During this sliding motion, under the elastic potential energy of the tension spring 28, the pull rod 27 is moved out from one end of the threaded tube 29, thus releasing the fixing of the threaded tube 29. The threaded pipe 29 is rotated, causing the threaded seat 30 to rotate as well. This rotation drives the screw 31 on the threaded seat 30 to rotate, causing the guide plate 32 on the screw 31 to slide along the guide groove 33 on the fixed sleeve 7. This movement stretches the spring plate 34, resulting in a higher water flow velocity when the spring plate 34 is stretched out and a lower water flow velocity when the spring plate 34 is uncompressed.

[0042] In summary, during the use or operation of the entire device: place the valve body 12 at one end of the fixed plate 4, aligning the connecting block 11 on the connecting pipe 5 with the connecting groove 13 on the valve body 12. Then, activate the cylinder 2 to move the movable plate 3 at the output end, thus clamping and fixing the valve body 12. Next, inject water into the water tank 14 along the inlet pipe 15. When it is necessary to remove the water, remove the plug 17 from the drain pipe 16 to discharge the water. Finally, activate the pump 37 to pump water along the inlet hose. 6 is fed into valve body 12, and pressure is measured by pressure gauge 18. After the test, water is fed from outlet hose 10 into water tank 14 by another pump 37. When the water flow needs to be adjusted, rotating ring 9 is rotated along moving ring 8, so that rotating rod 19 and rotating block 20 are rotated to pass through groove 36. Under the action of elastic potential energy of tension spring 22, moving moving ring 8 to the initial position, thereby releasing the fixation of adjusting ring 26.

[0043] After releasing the fixing of the adjusting ring 26, the driving gear 23 is rotated along the fixed sleeve 7. During rotation, the driven gear 25 meshing with the driving gear 23 is rotated, thereby causing the threaded rod 24 on the driven gear 25 to rotate. This causes the adjusting ring 26 to slide along the fixed sleeve 7. During sliding, under the elastic potential energy of the tension spring 28, the pull rod 27 is moved out from one end of the threaded tube 29, thereby releasing the fixing of the threaded tube 29. Then, the threaded tube 29 is rotated, causing the threaded seat 30 to rotate. During rotation, the screw 31 on the threaded seat 30 is rotated, causing the guide plate 32 on the screw 31 to slide along the guide groove 33 on the fixed sleeve 7. During this movement, the spring plate 34 is stretched. When the water flows in the fixed sleeve 7, the water flow velocity is larger when the spring plate 34 is stretched out, and smaller when the spring plate 34 is uncompressed.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
