Abstract
The invention discloses a plate replacing waterway module in a fuel gas heating water heater. The plate replacing waterway module comprises a water inlet valve, a water outlet valve and a plate type heat exchanger connected between the water inlet valve and the water outlet valve. A filtering net and a water flow sensor are arranged in a water inlet channel of a valve body of the water inlet valve. An adjusting valve rod which can adjust water flow is connected behind the water flow sensor in the water inlet channel of the valve body of the water inlet valve. A stepping motor is connected to the outer end of the adjusting valve rod and is used as a driving device. The stepping motor drives the adjusting valve rod to carry out screw transmission, and accordingly a gap between a cone section on the adjusting valve rod and the water inlet channel is changed. The stepping motor drives the adjusting valve rod to carry out screw transmission to achieve opening adjusting of the water inlet valve, and the purpose that water flowing out from the water outlet valve and a set value of a user are consistent is achieved. The action parameter of the stepping motor is determined according to the water flow information collected by the water flow sensor.
