Temperature control collar

Temperature adjustment valve

A valve device includes: a case having a valve chamber and first to third water communication ports communicating with the valve chamber; first and second valve bodies disposed in the valve chamber; and a shaft body connected with the first valve body. The first valve body is rotated about a central axis of the shaft part. The second valve body is rotated about the central axis together with the first valve body. When rotated about the central axis in a first angle region, the first valve body changes a first flow rate, i.e., a flow rate of water between the first and third water communication ports, and a second flow rate, i.e., a flow rate of water between the second and third water communication ports. When the first valve body is rotated about the central axis in a second angle region, the second valve body changes the second flow rate.
