The utility model relates to a draining temperature and flow limiting device for a cold or hot water adjusting valve, which is primarily characterized in that a box body of the cold or hot water adjusting valve is sheathed with a temperature limiting cap bag capable of being manually adjusted, and a rotating angle of a control rod in a horizontal direction can be adjusted and limited according to the limiting cap bag; high-temperature water flow can not flow out when a water tap is opened, and the effect of avoiding scalding of users can be reached; a wedge choke, the high-low position of which can be adjusted, is arranged on the control rod, and a pendulum placing angle of the control rod in a vertical direction can be limited by the wedge choke, which ensures that discharge of water-turbine pump can obtain proper abstinence when the water tap is opened. The effects of water saving, convenience, and practicality are obtained.
