The present invention provides a burning-proof cold/hot water balancing valve, which is accommodated in a holding space preset into a dual-temperature ceramic valve, comprising of a fixed valve pipe and moveable spool; the first and second ports of the fixed valve pipe are set oppositely to the first and second lateral end walls of the holding space; the moveable spool could shift transversely in the fixed valve pipe, and the hot and cold water slots of the moveable spool are separated by a partition; it is mainly characterized by that, a hot water stop flange is protruded from the first lateral end wall and meshed with the first end of the moveable spool to block off tightly hot water stream when the moveable spool shifts towards the first lateral end wall; moreover, a minimum cold water retaining portion is protruded from the second lateral end wall; when the moveable spool shifts towards the second lateral end wall, the minimum cold water retaining portion will be abutted onto the second end of the moveable spool, such that a minimum flow gap is reserved between the second end and the second lateral end wall, allowing for constant water flow through the cold water slot of the moveable spool; with this design, when the dual-temperature ceramic valve is switched to full hot water mode, the balancing valve could block off hot water flow to prevent scalding; when the dual-temperature ceramic valve is switched to full cold water mode, the balancing valve enables constant water flow to maintain normal cold water supply with better applicability. |
