[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0027] Reference Figure 1-3 This embodiment provides a portable electric valve flange opening and closing device, including a mounting disc 1. The mounting disc 1 has a polygonal through hole 11 in the center, and an annular mounting groove 12 is provided on the inner circumferential surface of the polygonal through hole 11. The polygonal through hole 11 can be used to clamp the installed mating parts.

[0028] The retaining ring 2 is circular and is installed in the annular mounting groove 12. The diameter of the retaining ring 2 is smaller than the diameter of the annular mounting groove 12 and larger than the diameter of the inscribed circle of the polygonal through hole 11. The retaining ring 2 has an opening 21. The shape of the retaining ring 2 can be temporarily changed through the opening 21, so as to facilitate the installation of the retaining ring 2 in the annular mounting groove 12.

[0029] The clip and component 3 includes a clamping ring 31 that engages with the snap ring 2 and a mounting portion 32 disposed on the clamping ring 31. Since the diameter of the snap ring 2 is larger than the diameter of the inscribed circle of the polygonal through hole 11 and smaller than the diameter of the annular mounting groove 12, the snap ring 2 can be movably disposed within the annular mounting groove 12. Thus, when installing the clip and component 3, the opening 21 can expand the snap ring 2, thereby facilitating the clamping of the side of the clip and component 3. The structure is simple and easy to disassemble and install.

[0030] The clamping claw 4 is detachably mounted on the mounting part 32 and is used for clamping and disassembling the valve flange. The clamping claw 4 clamps the valve flange, thereby enabling its disassembly. Because the clamping claw 4 is detachably mounted on the mounting part 32, the applicability of the device can be improved by replacing it with different shaped clamping claws. The various components in the device (such as the retaining spring 2, clamping component 3, clamping claw 4, etc.) adopt a modular design, facilitating individual disassembly and replacement, reducing maintenance costs and time. At the same time, this design also allows for rapid location and repair of the device in case of malfunction.

[0031] In summary, the card and component 3 are installed together inside the mounting disc 1. The snap ring 2 enables the card and component 3 to be connected and disconnected from the mounting disc 1. Then, the claw 4 is disassembled and installed on the card and component 3. The claw 4 can be rotated by rotating the mounting disc 1, thus clamping the claw 4 onto the valve flange, which facilitates the disassembly of the valve flange. By rotating the external mounting disc 1, the valve flange inside the box-type heat exchange station can be rotated and disassembled, eliminating the influence of the small space inside the box-type heat exchange station, which makes it inconvenient to rotate and disassemble the valve flange.

[0032] As an optional embodiment, the outer peripheral surface of the locking ring 31 is provided with a polygonal outer peripheral surface 311 that mates with the inner wall of the polygonal through hole 11. A groove 312 is provided in the middle of the polygonal outer peripheral surface 311 to engage with the retaining spring 2. A stepped surface 313 is provided at the end of the outer peripheral surface of the locking ring 31 away from the mounting part 32. When the locking ring 31 is pressed into the polygonal through hole 11, the stepped surface 313 contacts the retaining spring 2 first. During the movement of the locking ring 31, the diameter of the retaining spring 2 increases, allowing it to fully enter the annular mounting groove 12. This facilitates complete contact between the polygonal outer peripheral surface 311 and the polygonal through hole 11. At this time, the retaining spring 2 is engaged in the groove 312, and apart from the portion engaged with the locking ring 31, the remaining portion of the retaining spring 2 remains within the annular mounting groove 12. This achieves the fixation of the locking ring 31 to the mounting disc 1. The snap-fit ​​method also facilitates the removal of the locking ring 31, enabling a detachable connection.

[0033] As an optional embodiment, the mounting part 32 includes a mounting head 321 disposed on the clamping ring 31, and a mounting cover 322 disposed on the mounting head 321. The claw 4 is installed in cooperation with the mounting head 321. By fixing the claw 4 with the mounting head 321, the rotation of the mounting disc 1 can drive the rotation and disassembly of the claw 4.

[0034] As an optional embodiment, the mounting head 321 is provided with multiple mounting ports 3211, and the mounting ports 3211 are provided with threaded holes 3212. The mounting ports 3211 and threaded holes 3212 can be used to lock and limit the movement of the chuck 4.

[0035] As an optional embodiment, the chuck 4 includes a chuck head 41, a mounting body 42 disposed on the chuck head 41, and a locking bolt 43 disposed on the mounting body 42. The mounting body 42 is mounted on the mounting head 321 by the locking bolt 43, which passes through the mounting opening 3211 and is threaded into the threaded hole 3212 for a locking connection. By replacing the chuck 4 with different shapes, it can adapt to valve flanges of different specifications and types, improving the versatility and adaptability of the device. This flexibility allows the device to function effectively in various working environments.

[0036] As an optional embodiment, the locking bolt 43 includes a bolt body 431 and external threads 432 disposed at both ends of the bolt body 431. The external threads 432 engage with the threaded holes 3212 for locking.

[0037] As an optional embodiment, a drive assembly 5 is also included. The drive assembly 5 includes a meshing transmission rod 51 that meshes with the mounting disc 1, a connecting rod 52 disposed on the meshing transmission rod 51, and a transmission part 53 disposed on the connecting rod 52. Rotation of the meshing transmission rod 51 drives the meshing teeth 13 to rotate, thereby rotating the clamping assembly 3 and the clamping jaws 4, enabling the rotating disassembly of the flange clamped on the clamping jaws 4. The drive assembly 5 employs a meshing transmission method using the meshing transmission rod 51 and the meshing teeth 13, which features high transmission efficiency and a stable transmission ratio. This design ensures that the power output from the motor can be efficiently and accurately transmitted to the mounting disc 1 and the clamping jaws 4, achieving rapid opening and closing of the valve flange.

[0038] The outer circumferential surface of the mounting disc 1 is provided with meshing teeth 13 that mesh with the meshing transmission rod 51. The transmission part 53 is prior art and may include two transmission wheels and a transmission belt pressed against the outer circumferential surface of the two transmission wheels. When one transmission wheel rotates, it drives the other transmission wheel to continue rotating through the transmission belt, thereby causing the connecting rod 52 mounted on the other transmission wheel to rotate synchronously.

[0039] As an optional embodiment, the system also includes a motor 6, with a reducer 7 mounted on the output shaft of the motor 6. The output shaft of the reducer 7 is connected to the transmission unit 53. The reducer 7 lowers the speed of the motor 6, and then the transmission unit 53 connected to the reducer 7 drives the connecting rod 52, worm gear 51, and mounting disc 1 to rotate, thus transmitting power. Driven by the motor 6, the valve flange is electrically opened and closed, significantly improving work efficiency compared to traditional manual operation, especially in situations requiring frequent valve opening and closing, significantly reducing the operator's workload. Electric operation avoids the safety hazards of slippage and twisting that may result from direct manual rotation of the valve. Especially in confined spaces or when the valve is rusted or tightened, the electric opening and closing device can complete the operation more stably and reliably. Combined with the use of the reducer 7, the speed of the motor 6 can be precisely adjusted and controlled, thereby achieving precise control of the valve flange opening and closing speed. This precise control helps avoid valve damage or operational failure caused by excessively fast or slow opening and closing speeds.

[0040] As an alternative embodiment, such as Figure 1-5 As shown, it also includes a mounting housing 8, which includes a housing body 81 for mounting the drive assembly 5, the motor 6, and the reducer 7, and a mounting ring 82 disposed on one side of the housing body 81 for rotatably mounting the mounting disc 1. The mounting disc 1 is rotatably mounted within the mounting ring 82. The drive assembly 5, the motor 6, and the reducer 7 are all fixedly mounted within the housing body 81. The transmission part 53 is rotatably mounted on the housing body 81 and the mounting ring 82 to realize the transmission between the reducer 7 and the mounting disc 1.

[0041] As an optional embodiment, the mounting housing 8 also includes a portable handle 83 disposed on the housing body 81 and the mounting ring 82. The portable handle 83 facilitates the carrying and handling of the entire device. The device is designed with a mounting housing 8 and a portable handle 83, making the entire device compact, lightweight, easy to carry and move, and convenient for quick transfer and use between different work sites.

[0042] In summary, the clip and component 3 are pressed into the polygonal through hole 11, and the retaining ring 31 is fixed by the retaining spring 2. Then, the claw 4 is inserted into the clip and component 3, and the mounting body 42 is locked onto the mounting head 321 by the locking bolt 43. The claw 4 is clamped onto the valve flange. By starting the motor 6, the mounting disc 1 is rotated under the action of the reducer 7 and the drive component 5. The mounting disc 1 drives the clip and component 3 clamped on the mounting disc 1 to rotate, and the clip and component 3 drives the claw 4 to rotate. This allows the valve flange to be disassembled in a confined space.

[0043] All components of the device are made of high-strength materials and undergo precision machining and assembly, ensuring the device's durability and reliability. This durability enables the device to operate stably for extended periods in harsh working environments.

[0044] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
