Claims

[Scope of Claim for Utility Model Registration] A valve seat is formed in the middle of a hot water supply pipe, and a valve body that moves forward and backward by motor drive is inserted into the valve seat,
In a water heater flow rate adjustment/water shutoff valve device that is opened and closed by moving the valve body forward and backward along the valve seat, the valve body is formed of a synthetic resin material, and the valve is opened and closed by moving the valve body forward and backward along the valve seat. First, a flow rate adjustment hole consisting of a thin slit through which hot water passes and a continuous widening part is formed in the side wall of the valve body, and the valve body and the valve seat are moved until the valve body is fully removed from the valve seat. 1. A flow rate adjustment and water stop valve device for a water heater, characterized in that a fitting portion is formed on the valve body to ensure a fitting state with the valve body.
