Claim:
1. A single-handle dual-control thermostatic valve comprises a valve core body; a valve jacket hermetically-connected with an upper part of the valve core body; and a valve seat located at a bottom of the valve core body, wherein the valve core body and the valve seat form a space for accommodating a temperature regulating part and a water mixing zone; a flow part and a control part having a driver lever are provided in the valve jacket, while an upper end of the driving lever of the control part extends upwards out of the valve jacket; and the single-handle dual-control thermostatic valve is further characterized in that: a hot water incoming channel, a cold water incoming channel, a hot water outgoing channel and a cold water outgoing channel are provided separately in the valve core body, and the hot water incoming channel and the cold water incoming channel penetrate through the valve core body; the valve core body has a hot water inlet which connects with the hot water outgoing channel and the water mixing zone and a cold water inlet which connects with the cold water outgoing channel and the water mixing zone, and the hot water inlet and the cold water inlet are located at the positions with different heights in the valve core body; a static ceramic chip having a hot water inlet passage, a hot water outlet passage, a cold water inlet passage and a cold water outlet passage is provided above the valve core body in the valve jacket, a dynamic ceramic chip having a hot water controlling channel and a cold water controlling channel is provided on the static ceramic chip, the dynamic ceramic chip is connected with the control part and can rotate and translate by the control part, wherein the hot water inlet passage, the hot water outlet passage, the cold water inlet passage and the cold water outlet passage are connected correspondingly with the hot water incoming channel, the hot water outgoing channel, the cold water incoming channel and the cold water outgoing channel of the valve core body respectively, the hot water controlling channel can open or shut off both the hot water inlet passage and the hot water outlet passage on the static ceramic chip, and the cold water controlling channel can open or shut off both the cold water inlet passage and the cold water outlet passage on the static ceramic chip; and a mixed water outlet is located on the valve seat and connected with the water mixing zone.
