Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, specifically to an auxiliary tooling for valve testing. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, and pressure relief. During use, valves are often used to control the opening and closing of high-pressure liquid or gas lines; therefore, their airtightness is a critical requirement. Valves undergo various tests and inspections before leaving the factory, requiring the use of auxiliary tooling during these tests.

[0003] Existing auxiliary fixtures for fixing valves have significant limitations, as they are only compatible with valves of a single size and lack flexibility. In practice, when faced with valves of different sizes, it is not easy to adjust the fixing structure accordingly. This not only reduces testing efficiency but also increases the time and labor costs due to frequent fixture changes. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] See Figure 1-4A valve testing auxiliary tooling includes a main component 1, which includes: a base 11 with a side plate 12 fixedly connected to its outer side wall; a connecting mechanism 13 disposed on the top of the base 11; a fixing component 2 disposed on the base 11 and the side plate 12, the fixing component 2 including: a cavity 21 formed inside the side plate 12; a rotating shaft 22 rotatably connected to the inner side wall of the cavity 21; a gear 23 fixedly connected to the outside of the rotating shaft 22; and a rack 24 slidably connected to the inner side wall of the cavity 21, the rack 24 meshing with the gear 23; the rack... Rack 25 is slidably connected to the inner wall of the cavity 21, and the rack 25 meshes with the gear 23; connecting block 251 is symmetrically and fixedly connected to the side of rack 1 and rack 25 near the base 11, and the side plate 12 has a through groove for the connecting block 251 to move; fixing block 26 is symmetrically and slidably connected to the top of the base 11, and the fixing block 26 is fixedly connected to the connecting block 251 in sequence; controller 211 is set on the right side wall of the side plate 12; drive mechanism 27 is set on the controller 211 and the rotating shaft 22. The drive mechanism 27 includes: a base plate 271, fixedly connected to the outer wall of the side plate 12; a motor 272, disposed on the top of the base plate 271, the motor 272 being electrically connected to the controller 211; and a rod 273, one end of which is fixedly connected to the output shaft of the motor 272, the other end of which passes through and extends into the cavity 21 and is fixedly connected to the rotating shaft 22. Dovetail blocks 6 are fixedly connected to the back sides of both the rack 1 24 and the rack 25. Dovetail grooves 61 are symmetrically formed on the inner wall of the cavity 21, and the dovetail blocks 6 are slidably connected within the dovetail grooves 61.

[0042] In use, the operator places the valve to be tested between the fixed blocks 26 and starts the motor 272. The motor 272 drives the rotating shaft 22 to rotate clockwise via the drive mechanism 27. After the motor 272 starts, it drives the rod 273 to rotate clockwise, causing the rotating shaft 22, which is fixedly connected to the rod 273, to rotate. The rotating shaft 22 drives the gear 23 to rotate clockwise. The racks 24 and 25 meshing on both sides of the gear 23 simultaneously drive the connecting block 251 to move closer together. The fixed block 26 connected to the connecting block 251 moves towards the center and fixes the valve. Since the fixed block 26 is movable, the device can easily fix valves of different diameters. After the valve is fixed, the connecting mechanism 13 connects the valve to the testing device, facilitating subsequent valve testing. When gear 23 moves in conjunction with rack 24 and rack 25, the dovetail blocks 6 on rack 24 and rack 25 slide in the dovetail groove 61. The dovetail blocks 6 and the dovetail groove 61 guide the movement of rack 24 and rack 25, thereby increasing the stability of rack 24 and rack 25 during movement and facilitating the movement of connecting block 251.

[0043] The aforementioned connection mechanism 13 includes connection interfaces for various testing equipment such as pressure sources and flow meters, enabling the test medium to be accurately input into the valve and facilitating the measurement and monitoring of various valve performance parameters. As long as the connection testing of the valve can be achieved, the specific structure will not be elaborated upon here.

[0044] Example 2

[0045] An auxiliary function has been added based on Embodiment 1.

[0046] See Figure 1-4 The fixing blocks 26 have protective pads 4 on their opposing surfaces. The top of the base 11 is symmetrically and fixedly connected to brackets 31, and sliding rods 3 are fixedly connected between the brackets 31. Sliding blocks 32 are symmetrically and fixedly connected to the outer walls of the fixing blocks 26, and the sliding blocks 32 are slidably connected to the sliding rods 3. A pressure sensor 5 is embedded in the inner wall of one of the fixing blocks 26, and the pressure sensor 5 is electrically connected to the motor 272 through the controller 211.

[0047] When the fixing block 26 secures the valve, the protective pad 4 contacts the valve surface. The protective pad 4 prevents the hard material of the fixing block from scratching or abrading the valve shell. Especially for valves with coatings, high precision requirements, or soft materials, the protective pad maintains the integrity of the valve's appearance, ensuring its normal use and aesthetics. When the fixing block 26 moves to secure the valve, it drives the slider 32 to slide on the slide rod 3. The slider 32 and slide rod 3 guide the end of the fixing block 26 away from the side plate 12, thereby increasing the stability of the fixing block 26 during movement and facilitating timely and accurate valve securing. During the process of fixing the valve with the fixing block 26, the pressure sensor 5 monitors the pressure between the valve and the fixing block 26. When the pressure exceeds a predetermined value, the pressure sensor 5 sends the pressure data to the controller 211 via an electrical signal. The controller 211 then controls the motor 272 to shut down, thereby preventing the fixing block 26 from continuing to move and ensuring a secure fixation of the valve while avoiding damage to the valve.
