1. A valve device, comprising:
a case;
a first valve body and a second valve body; and
a shaft body connected with the first valve body,
wherein the case has a valve chamber and a first water communication port, a second water communication port, and a third water communication port in communication with the valve chamber,
the first valve body and the second valve body are disposed in the valve chamber,
the first valve body is rotated about a central axis of the shaft body,
the second valve body is rotated about the central axis together with the first valve body,
when the first valve body is rotated about the central axis in a first angle region, a first flow rate and a second flow rate are changed by the first valve body, wherein the first flow rate is a flow rate of water flowing between the first water communication port and the third water communication port, and the second flow rate is a flow rate of water flowing between the second water communication port and the third water communication port,
when the first valve body is rotated about the central axis in a second angle region, the second flow rate is changed by the second valve body.
