Abstract
A valve device includes a cold water inlet and a hot water inlet communicating with a chamber, and one or more ports, a valve housing received in the chamber of the valve device and having a channel for receiving a safety valve. A valve element is engaged in the valve housing for controlling the flowing of the hot water and the cold water through either of the ports. The safety valve may be used for shutting off the hot water when the cold water is shut off inadvertently, so as to prevent the users from being hurt by the hot water inadvertently.
