Valve with motor actuation for gas flow regulating

摘要

The Motorized valve for gas flow control in a water heater is normally closed by a return spring and the motor (51) drives a cam plate (52) when electrically switched to move a magnet (32) into proximity to another magnet (31) to cause a coil to charge. The movement of the cam plate driven magnet inside the valve housing (10) allows the valve lever (20) and valve pin to move away from the valve opening (40).
