Specifically, as shown in FIG. 1, a weir (9) is provided in the middle of the flow path (8), and the upper part of the flow path (8) in the direction of the flow of the arrow is provided. The first channel (8
a), the flow path (8) below the flow direction indicated by the arrow, that is, the flow path (8) in the flow portion ahead of the weir (9) is set to the second direction.
When the weir (9) is opened and closed as necessary, the flow rate of the second flow path (8b) is the same as the flow rate of the first flow path (8a). It can be reduced or stopped altogether.

As shown in FIG. 1, the solenoid valve body (4) is disposed immediately inside an outer casing (5) of the device. Examples of this device include devices such as a circulating purification device and a heat retention device, but are not limited thereto, and can be employed in various devices. A coil (6) is wound around the solenoid valve body (4) as shown in FIG.
