<p>This invention relates to a solenoid valve for mixing liquids which controls the flow of a liquid. In conventional solenoid valves for mixing liquids, an electromagnet driving portion and a valve portion are disposed adjacent to each other and a plunger of the electromagnet portion and a valve body of the valve portion are connected with a valve rod having high rigidity. However, since a liquid remains inside a pipe that extends from the valve portion of the solenoid valve for mixing liquids and the liquid is dried up at the valve portion by the heat of coil transferred to the valve body, the concentration of the liquid becomes different and accurate mixing cannot be made. To solve these problems, the solenoid valve (1) for mixing liquids in accordance with the present invention separates the electromagnet driving portion (2) from the valve portion (3), connects them with tubular member (38), disposes the valve portion (3) at the tip of this tubular member (38) and connects the valve body (48) of the valve portion (3) to the plunger (28) of the electromagnet driving portion (2) with a wire member (36) inserted through the tubular member (38). As a result, the pipe for delivering the liquids can be shortened or eliminated so that no liquid remains inside the pipe and, since the heat of the coil (21) of the electromagnet driving portion is not transferred easily to the valve body (48), the liquid is neither dried up nor adheres to the valve portion (2). Accordingly, accurate mixing can be made.</p> |
