Description

Technical Field

[0001] The utility model relates to the technical field of manual actuating devices, and more specifically, to a manual actuating device. Background Art

[0002] In the existing technology, the design of the valve body manual actuating device has certain limitations during use. Traditional valve bodies usually rely on motor drive for rotation, which can provide a convenient operation experience when the motor is working properly. However, once the motor fails or malfunctions, when users need to operate the valve body manually, they will find that it is difficult to rotate. This is because while the motor provides the rotational torque, it also bears most of the operating load. When the motor cannot work, users must rely on their own strength to overcome the friction and inertia of the valve body, which is often very inconvenient in actual operation.

[0003] In this case, the manual operation of the valve body not only requires a large amount of physical strength, but may also be inefficient due to inconvenient operation, and there may even be safety risks. Especially in an emergency, if the valve body cannot be quickly opened or closed manually, it may have an adverse impact on the entire system, such as leakage, abnormal pressure, etc. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0013] The present utility model is further configured such that a motor is provided on the chuck, and the motor is cooperatively connected to the transmission sleeve. Such a configuration enables the motor to drive the rotation of the chuck through the transmission sleeve, thereby realizing the automatic adjustment of the valve body, improving the convenience and efficiency of the operation.

[0014] The present utility model is further configured such that a handwheel is coaxially provided on the intermediate rod. Such a design enables the handwheel to be coaxially provided on the intermediate rod. By manually rotating the handwheel, the rotation of the sealing disc can be realized, thereby providing a way to manually adjust the valve body when the motor fails, enhancing the flexibility and reliability of the operation.

[0029] Please refer to Figures 1-5, A manual execution device, including a valve body 1, the valve body 1 is installed on an external device, a telescopic mechanism is provided on the valve body 1, the telescopic mechanism includes a rotating mechanism, a bottom plate 2, a guide rod 3, a chuck 4, a bottom rod 5, an intermediate rod 6, a transmission sleeve 7, a hexagonal sleeve 8 and a clamping mechanism. The rotating mechanism is cooperatively connected to the valve body 1 and the bottom rod 5. The bottom plate 2 is installed on the valve body 1. There are multiple guide rods 3, and the multiple guide rods 3 are respectively connected to the bottom plate 2 and the chuck 4. The bottom rod 5 is rotatably connected inside the bottom plate 2. The intermediate rod 6 is installed on the bottom rod 5. The transmission sleeve 7 is rotatably connected to the chuck 4 and the intermediate rod 6. The hexagonal sleeve 8 is installed on the transmission sleeve 7, and the hexagonal sleeve 8 is sleeved on the transmission sleeve 7. The clamping mechanism is installed on the hexagonal sleeve 8. The clamping mechanism includes a clamping sleeve 9 and an intermediate sleeve 10. The clamping sleeve 9 is clamped and slidably connected to the hexagonal sleeve 8 and the bottom rod 5. The intermediate sleeve 10 is slidably connected to the guide rod 3. The clamping sleeve 9 is rotatably connected to the intermediate sleeve 10. A push plate 11 is coaxially provided on the side wall of the intermediate sleeve 10. Multiple elastic plates 12 are provided on the side wall of the push plate 11. A clamping ball 13 is provided on each elastic plate 12. The clamping ball 13 is stuck on the chuck 4. A spring 14 is coaxially provided on the intermediate sleeve 10. The spring 14 abuts against the chuck 4. The rotating mechanism includes an intermediate shaft 15 and a sealing plate 16. The intermediate shaft 15 passes through the valve body 1 and is installed on the bottom rod 5. The sealing plate 16 is installed on the intermediate shaft 15. A motor 17 is provided on the chuck 4. The motor 17 is cooperatively connected to the transmission sleeve 7. A handwheel 18 is coaxially provided on the intermediate rod 6.

[0030] In this embodiment, when the motor 17 fails and manual adjustment of the valve body 1 is required, first drive the movement of the push plate 11 so that the spring 14 is compressed. Since the clamping sleeve 9 has been slidably connected to the hexagonal sleeve 8, when the intermediate sleeve 10 moves upward, the connection between the clamping sleeve 9 and the bottom rod 5 will be released. Then, the clamping ball 13 on the elastic plate 12 will cross over the chuck 4, and under the elastic force of the elastic plate 12, the push plate 11 will be fixed. Then, the spring 14 is compressed to release the connection between the transmission sleeve 7 and the bottom rod 5. Then, at this time, by rotating the handwheel 18, since the handwheel 18 is connected to the intermediate rod 6, the rotation of the sealing plate 16 will be driven, thus completing the adjustment process.

[0031] More specifically, when the motor 17 resumes use, by applying an external force, the connection between the clamping ball 13 and the chuck 4 is released, and then under the action of the spring 14, the clamping sleeve 9 is respectively stuck on the bottom rod 5 and the hexagonal sleeve 8, thereby ensuring the transmission of the motor 17 and further completing the use of the valve body 1.

[0032] In summary, when the overall device is in use or operation: when the motor 17 fails and the valve body 1 needs to be manually adjusted, first drive the movement of the push plate 11 to compress the spring 14. Since the ferrule 9 has been slidingly connected to the hexagon sleeve 8, when the intermediate sleeve 10 moves upward, the connection between the ferrule 9 and the bottom rod 5 will be released. Then, the locking ball 13 on the elastic plate 12 will cross over the chuck 4, and under the elastic force of the elastic plate 12, the push plate 11 will be fixed. Then, the compression of the spring 14 releases the connection between the transmission sleeve 7 and the bottom rod 5. At this time, by rotating the handwheel 18, since the handwheel 18 is connected to the intermediate rod 6, it will drive the rotation of the sealing disc 16, thus completing the adjustment process. When the motor 17 resumes use, apply an external force to release the connection between the locking ball 13 and the chuck 4, and then under the action of the spring 14, the ferrule 9 is respectively clamped on the bottom rod 5 and the hexagon sleeve 8, thus ensuring the transmission of the motor 17 and further completing the use of the valve body 1.
