Electric-regulating gas flow valve gear

The utility model discloses an electric-regulating gas flow valve device used for a domestic gas kitchen range including a valve body, a valve core, a position switch of the valve core, a poking blade, a direct current motor, a deceleration gear set, a counter gear, a counter circuit board, a support cap of the deceleration gear set, and an electronic control system, etc. The signal line of the position switch of the valve core, the power line of the motor and the pulsing signal line given out by the counter circuit board are connected with the electronic control system. The motor and the valve body are closely connected with the support cap of the deceleration gear set and one side of the gear on the output shaft of the motor is combined with the initial gear of the deceleration gear set and the other side of the gear on the output shaft of the motor is combined with the counter gear. The output gear shaft of the deceleration gear set is connected with the valve core. The position switch of the valve core fixed on the valve body is poked by the poking blade fixed on the valve core. The counter circuit board is fixed on the upper of the counter gear. When rotating, pulsing signal generates between the counter gear and the counter circuit board and gives out to the electronic control system. The utility model is safe and reliable to run and the flow rate is stepless adjustable.
