Description

Technical Field

[0001] This invention relates to the field of valve testing technology, specifically to a valve testing device. Background Technology

[0002] Every valve product undergoes a series of performance tests before leaving the factory, including valve sealing tests. The immersion test is one of the most common sealing test methods. Its core principle is to use air bubbles to visually identify the leak point. It is suitable for medium and low pressure valves, small valves, or scenarios where the location of the leak point is critical.

[0003] When testing valves using the immersion method, both ends of the valve are typically sealed. The valve is then placed entirely in a test tank using a vertically moving drive device. Pressurized gas is then injected into the valve, and the presence of continuous bubbles rising to the surface is observed. If continuous bubbles are observed, it indicates a leak. After the valve is removed from the tank, residual moisture will remain on its surface. If the valve is stored or transported in a low-temperature environment, this residual moisture can freeze and expand, potentially cracking thin-walled parts such as the valve body and cover, causing irreversible structural damage. Furthermore, long-term storage can lead to the growth of bacteria within the valve's internal cavity. Mold and scale buildup can affect valve performance. Therefore, to ensure customer satisfaction with the valves, it is necessary to clean the residual moisture on the valve surface after inspection. Manual wiping is inefficient, and if moisture remains inside the valve, it not only increases the workload of staff but also significantly reduces the efficiency of cleaning. If the valves are transferred to a dedicated drying device, they are usually dried simultaneously after a large number of valves have been inspected. To ensure that multiple valves are thoroughly dried, the required drying time is also long, which is not conducive to the efficiency of subsequent valve transfer. Summary of the Invention

The two drive plates 35 cooperate with their respective connecting rods 21. A rack 32 is fixedly installed on the top of the drive ring 34. The rack 32 meshes with the drive gear 31.

[0037] The flipping mechanism includes a flipping motor 26 and a flipping rod 27. The flipping motor 26 is fixedly installed on the outside of the workbench 1. The flipping rod 27 is rotatably installed on the top of the drying chamber 6 and is fixedly connected to the output shaft end of the flipping motor 26. Both ends of the flipping rod 27 are fixed with connecting brackets 28. The ends of the two connecting brackets 28 away from the flipping rod 27 are respectively fixedly connected to their corresponding frames 14.

[0038] Working principle: In use, the valve to be tested is first placed in two sealing devices 5 to seal both ends of the valve. Then, the two sealing devices 5 are lowered into the test pool 2 by two lifting devices 4. Pressurized gas is introduced into the valve and the water surface is observed to see if there are continuous bubbles overflowing. The sealing performance of the valve is tested. The lifting device 4, the sealing device 5 and how to introduce pressurized gas into the valve are all existing technologies and will not be described in detail here.

[0039] After the valves are inspected, the two valves are placed on top of the two support seats 7 respectively, with the two ends of the two valves located inside the two semicircular grooves 8 respectively. At this time, the two ends of the two valves are also located inside the corresponding semicircular grooves 16 respectively. The two support seats 7 support the two valves respectively. Then, the two transfer mechanisms are operated. The operation process of one transfer mechanism is as follows: the cylinder 24 is started, which pulls the frame 15 below it to move upward. During the rise of the frame 15, the guide rod 25 slides at the end of the frame 14 or the frame 15. The setting of the guide rod 25 ensures that the frame 15 can rise stably. During the rise of the frame 15, the valve above it is lifted and rises synchronously. After the cylinder 24 stops, the opposite sides of the frame 14 and the frame 15 are attached, and the top and bottom of the two ends of the valve are located inside the corresponding semicircular grooves 16 respectively. The operation process of the other transfer mechanism is the same as above.

[0040] Then, the flip motor 26 is started, driving the flip rod 27, which is fixedly connected to its drive end, to rotate, thereby causing the two connecting brackets 28 to rotate. The two connecting brackets 28 drive their respective corresponding frames 14 to rotate, thereby driving the two valves to rotate and move the two valves into the two drying devices. The purging process of one of the drying mechanisms is as follows: The input pipe 13 is connected to the air compressor. By introducing gas into the input pipe 13, since multiple arc-shaped pipes 11 are all connected, and the two outermost arc-shaped pipes 11 are respectively connected to the two coils 10, when gas is introduced into the input pipe 13, whether it is multiple arc-shaped pipes 11 or... Both of the purge nozzles 12 in the two coils 10 can spray dry gas onto the valve; the purging process of the other drying mechanism is the same as described above. The two drying mechanisms respectively dry both sides and part of the valve surface. By setting a drying chamber 6 at one end of the workbench 1, after the valve is inspected, the valve can be placed inside the drying chamber 6. Through the cooperation of the transfer mechanism, the flipping mechanism and the drying mechanism, the surface of the valve and the interior of both ends can be dried. There is no need to manually wipe or transfer to a special drying device for drying. Moreover, the drying efficiency is fast, which is beneficial to improving the subsequent transfer efficiency of the valve.

[0041] During the movement of the two frames 14 and 15 into their respective drying units, multiple clamping assemblies operate accordingly. The movement of one clamping assembly is as follows: the two connecting rods 21 gradually approach their respective extrusion supports 36. When the two connecting rods 21 contact the ends of the extrusion supports 36, as the corresponding frame 14 continues to rotate, the two connecting rods 21 are forced to move towards the valve. The springs 23 on one side of the two connecting rods 21 are compressed. Simultaneously, the two connecting rods 21 move, causing their respective clamping blocks 22 to move towards the valve. The two clamping blocks 22 then press tightly against the valve surface. The movement of the other clamping assemblies is the same as described above. The two valves are clamped and fixed by two clamping assemblies respectively. At this time, the transmission mechanism is activated. The motion process of a transmission mechanism is as follows: The transmission motor 30 is started, which drives the transmission gear 31 connected to its drive end to rotate. The rack 32 drives the transmission ring 34 to rotate. The two transmission plates 35 on one side of the transmission ring 34 rotate synchronously. The two transmission plates 35 act on the connecting rods 21 on the same side of the corresponding frame 14 and frame 25 respectively. As the two transmission plates 35 rotate, the two ends of the corresponding sliding rods 20 slide along their respective arc grooves 17 and arc rods 18. The corresponding spring 19 is compressed. At this time, the two clamping components rotate, thereby causing the corresponding valve to rotate at a certain angle, so that the blind area of ​​the valve that has not been dried is rotated to a position that the drying mechanism can blow, ensuring that the entire valve can be blown by the drying mechanism, thus ensuring the overall drying effect of the valve.

[0042] After the drying process is completed, the two cylinders 24 are activated simultaneously, causing the two frames 14 to move away from their respective corresponding frames 15. At this time, the two valves fall downward into the bottom of the drying chamber 6 under the action of gravity and slide into the external receiving plate 29 for easy access by the staff.
