Energy saving-burn-proof single handle valve structure

摘要

A water temperature sensing/flow control mixing valve has a valve body 18 with hot 22 and cold 24 water inlets and at least one outlet 26. A mixing valve member 16 is positioned within the valve body and controls the proportion of hot and cold water that flows from the outlet. A water flow restrictor 44 is positioned within the valve body and movable from a normal flow position in which outlet flow is unobstructed to a position in which the restrictor partially closes the outlet to limit flow therefrom. There is a shaped memory metal actuator 16 positioned within the valve body 18 to move the restrictor 44 from the normal flow position to the flow limiting position when the water within the valve body exceeds a predetermined temperature.
