Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heating system, especially to a multi -pass water valve group. BACKGROUND

[0002] Water heater is one of the necessary equipment in modern family life, and the water inlet valve and the water outlet valve are two important components in the water heater, which are used to control the inflow and outflow of hot water. Specifically, the water inlet valve is the water source inlet of the water heater, which is used to control the inflow of water; while the water outlet valve is the water outlet of the water heater, which is used to control the outflow of hot water.

[0003] Although the water inlet valve and the water outlet valve in the water heater are both used to control the inflow and outflow of water, their working principles are different. The water inlet valve is usually an electromagnetic valve, which opens when the user turns on the water heater switch, and the water flows into the water heater through the water inlet pipe, so that the water heater can be used. On the other hand, the water outlet valve is usually manual or remote controlled, and when it is opened, the hot water flows out of the water heater through the water outlet pipe and can be used.
