[0033] Reference Figs. 1 to 4 A hand-electric integrated gas valve with an electric clutch includes a valve body 100, an electric clutch 200, and a drive motor 300. The valve body 100 includes a valve body 110 and a valve spindle 120, and the valve spindle 120 is rotationally arranged in the valve body 110. The electric clutch 200 is installed on the valve body 110, and the electric clutch 200 is provided with a center hollow shaft 210, a rotating wheel 220, and an electric coupling mechanism. The rotating wheel 220 and the center hollow shaft 210 are coaxially arranged, the center hollow shaft 210 is sleeved on the valve spindle 120 and rotates with the valve spindle 120, and the electric coupling mechanism is used to drive the center hollow shaft 210 and the rotating wheel 220 into a state of rotating together and a state of disengaging linkage. When the center hollow shaft 210 and the rotating wheel 220 enter the state of disengaging linkage, the rotating wheel 220 can freely idle relative to the center hollow shaft 210. The drive motor 300 is installed on the valve body 110, and the output shaft of the drive motor 300 is linked with the rotating wheel 220 through a linkage structure 400 and can drive the rotating wheel 220 to rotate through the linkage structure 400.

[0034] When electric control is needed, the center hollow shaft 210 and the rotating wheel 220 can be brought into a rotating state together through the electric coupling mechanism of the electric clutch 200, the driving motor 300 can drive the rotating wheel 220 to rotate through the linkage structure 400, thereby driving the center hollow shaft 210 and the valve spindle 120 to rotate, and the control of the gas valve is realized; when switching to the manual mode, the center hollow shaft 210 and the rotating wheel 220 are disconnected through the electric coupling mechanism of the electric clutch 200, so that the rotating wheel 220 can freely idle, and the valve spindle 120 can rotate independently, thereby realizing the manual control of the gas valve. The above-mentioned gas valve integrates the manual control and the electric control structure, and the function switching can be realized through the electric clutch 200. When in the manual control state, the rotation of the valve spindle 120 will not drive the motor shaft of the driving motor 300 to rotate, so as not to affect the angle state of the driving motor 300 and increase the operation damping, and the linkage isolation is formed between the driving motor 300 and the valve spindle 120, avoiding mutual influence.
