Embodiment Construction
[0024] Such as Figure 1 to Figure 7 As shown, this embodiment discloses a plate replacement waterway module in a gas-fired heating water heater, which is used to control the flow of bathing water. It includes a water inlet valve 1, a water outlet valve 2 and a plate heat exchanger 3 connected between them.
[0025] The water inlet channel of the water inlet valve 1 valve body is built with a filter screen 11, a water flow sensor 12, a guide seat 13 and a regulating valve stem 14, and the outer end of the regulating valve stem 14 is connected with a stepping motor 4 through a structure similar to a spline. as its drive. The stepper motor 4 is installed and fixed through the connecting plate 5 on the valve body of the water inlet valve 1 . The filter screen 11 and the water flow sensor 12 are respectively installed and fixed through corresponding sleeves 16 .
[0026] The two ends of the regulating valve stem 14 are respectively the driving device connecting section 141 and ...

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.
Description
technical field [0001] The invention relates to a gas heating water heater, in particular to an internal waterway system of a gas heating water heater. Background technique [0002] The plate-changing waterway module is a key component of the internal waterway system of the wall-hung boiler, including water inlet valves, water outlet valves and plate heat exchangers, and integrates functions such as waterway switching, water replenishment, and bathing water inlet flow detection. The existing plate-changing waterway module does not have the function of automatically adjusting the bath water flow, and the user needs to add a valve to manually adjust the bath water flow. When the bathing water inlet pressure fluctuates, the existing board-changing waterway module cannot maintain the bathing water flow at the user's set value; when the water flow changes, the bathing water temperature will fluctuate correspondingly for a period of time; it cannot satisfy the user's high quality ...
