[0002] The gas cock is a common valve body structure used in stoves. It adjusts the opening and closing of the gas channel and the gas flow rate through a mechanical structure by rotating the valve core. In order to adapt to the concept of electronic smart kitchen cooking, an electric gas valve that uses a motor to control and adjust the gas channel has appeared on the market, such as the electric control cock disclosed in patent number CN202222493913.4. It uses a motor to drive the valve stem and valve plug to rotate, realizing intelligent adjustment and control of the gas channel.
