[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-4A ball valve actuator includes a housing 1. A mounting plate 2 is fixed between the inner walls of the housing 1 on multiple sides by bolts. A circuit board 3 is fixed to the top of the mounting plate 2 by bolts. The top of the circuit board 3 is electrically connected to a power-off switch 15 and a battery pack. A transmission shaft 4 is slidably inserted into the top of the mounting plate 2, and the transmission shaft 4 can be rotatably connected to the mounting plate 2. The top of the transmission shaft 4 passes through the top of the housing 1 and is fixed with a rotating shaft 11 by bolts. Rotating the rotating shaft 11 drives the transmission shaft 4 to rotate, thereby driving the valve stem to rotate, thereby realizing manual opening and closing of the valve. The mounting plate 2 is fixed with a motor 6 by bolts, and the output end of the motor 6 is keyed to a driving gear 7. A reduction gear set 8 is provided at the bottom of the mounting plate 2, and the reduction gear set 8 is meshed with the driving gear 7. The circumferential outer wall of the transmission shaft 4 is keyed to a driven gear 9, and the driven gear 9 can mesh with the reduction gear set 8. The driving gear 7 rotates under the drive of the motor 6, and then, under the action of the meshing of the driving gear 7 with the reduction gear set 8 and the meshing of the reduction gear set 8 with the driven gear 9, the transmission shaft 4 is driven to rotate, thereby driving the valve stem to rotate, thereby realizing automatic opening and closing of the valve;

[0023] A rotating shaft is rotatably plugged into the top of the mounting plate 2, and a rotating disk 13 is welded to the outer wall of the rotating shaft. A protrusion 14 is fixed to the bottom of the rotating disk 13 by bolts. The protrusion 14 can press on the power-off switch 15. The top end of the rotating shaft passes through the top of the housing 1 and is fixed with a rotating knob 12 by bolts. Turning the rotating knob 12 drives the rotating disk 13 to rotate, thereby driving the protrusion 14 to rotate and press on the power-off switch 15, thereby cutting off the power to the battery pack for manual operation.

[0024] The power-off switch 15 is electrically connected to the battery pack, a sealing ring 5 is sleeved on the outer wall of the transmission shaft 4, a universal joint 10 is provided at the bottom of the outer shell 1, and the universal joint 10 is connected to the bottom end of the transmission shaft 4, thereby facilitating the connection between the universal joint 10 and the valve stem of the valve, the protrusion 14 has a trapezoidal structure, a wiring port 16 is provided at the bottom of the outer shell 1, and an anti-slip groove is provided on the rotating knob 12.

[0025] The working principle of this embodiment is as follows: when in use, the valve is connected to the universal connector 10. When automatic operation is required, the motor 6 is started, and the driving gear 7 is rotated under the drive of the motor 6. Then, under the action of the driving gear 7 meshing with the reduction gear set 8 and the meshing of the reduction gear set 8 with the driven gear 9, the transmission shaft 4 is driven to rotate, thereby driving the valve stem to rotate, thereby realizing the automatic opening and closing of the valve;

[0026] When manual control is required, the rotating knob 12 is turned to drive the rotating disk 13 to rotate, thereby driving the protrusion 14 to rotate and press on the power-off switch 15, thereby cutting off the power to the battery pack. The rotating shaft 11 is pressed to drive the transmission shaft 4 to move downward, thereby driving the driven gear 9 to move downward, and then separating the driven gear 9 from the reduction gear group 8. Then, the rotating shaft 11 is pressed and turned to drive the transmission shaft 4 to rotate, thereby driving the valve stem to rotate, thereby realizing manual opening and closing of the valve.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
