Abstract: A cold/hot water balance valve prevents burning or scalding of the users. The valve is accommodated in the holding space preset into a dual-temperature ceramic valve. The balance valve mainly includes a hot water stop flange, protruded from a first lateral end wall, and meshed with a first end of a moveable spool to block a hot water stream when the first end shifts towards the first lateral end wall. A minimum cold water retaining portion is protruded from the second lateral end wall. When the second end of 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 flow of water stream through the cold water slot of the moveable spool.

Abstract: A balance valve is provided with an asymmetric structure. When the dual-temperature ceramic valve is switched to cold water supply modes, and the hot water line is blocked to make a moveable spool abutted towards a first lateral end wall of a holding space, a cold water channel can thus be formed between the cold water opening of a fixed valve pipe and a second end of the moveable spool with the setting of the asymmetric structure. Hence, cold water supply can maintained. When the hot water line is blocked, the cold water supply function of the balance valve of the present invention could still be maintained for improved convenience and applicability.

Abstract: A balance control valve with improved operational sensitivity is accommodated in the holding space preset into the dual-temperature ceramic valve. Annular grooves are located correspondingly to the cold water opening and hot water opening of the fixed valve pipe. An unscaling portion is formed between the annular grooves and the inner wall of the fixed valve pipe in a vertical configuration, and is used to remove scale generated on the exterior of the moveable spool. The setting width of the annular groove is equal to or greater than the width of the cold water opening and hot water opening. With the setting of the annular groove, the contact area of the moveable spool and the inner wall of the fixed valve pipe could be reduced so as to improve the operational sensitivity of the moveable spool, remove the scale and extend the service life of the balance control valve.

Abstract: A cold and hot water balancing valve assembly which can fit common standard specifications. The bottom ends of the cold and hot water through holes of the high legged seat are configured with a water inlet pipe set housing groove for fitting an eccentrically positioned assembled water inlet pipe set, which are made up of cold and hot water tubes. When the meshing edges of the cold and hot water tubes are joined together, a balancing valve housing space is defined inside to hold a cold and hot water balancing valve unit. The cold and hot water balancing valve assembly dramatically reduces the production cost of cold-hot balancing valves while realizing the cold and hot water balancing function.

Abstract: A cold and hot water balancing valve structure is provided which can fit common standard specifications. While maintaining the outer diameter and height of the high legged seat of the valve enclosure under existing standard specifications of ceramic valves, the bottom ends of the cold and hot water through holes of the high legged seat are configured with a water inlet pipe set housing groove for fitting an eccentrically positioned assembled water inlet pipe set, which are made up of cold and hot water tubes. When the meshing edges of the tubes are joined together, a balancing valve housing space is defined inside to hold a cold and hot water balancing valve unit. The cold and hot water balancing valve structure fits existing standard ceramic valve specifications, so as to dramatically reduce the production cost of cold-hot balancing valves while realizing the cold and hot water balancing function.

Abstract: A balance valve with improved operational sensitivity is accommodated in the holding space preset into the dual-temperature ceramic valve. The balance valve has a fixed valve pipe and a moveable spool. The fixed valve pipe has a first port, a second port and cold/hot water openings. An inner wall is formed in the fixed valve pipe. The moveable spool is transversely assembled into the inner wall of the fixed valve pipe in a transverse movement state. Both ends of the moveable spool are recessed to form hot/cold water slots, which are separated by a partition. Inner grooves are recessed onto the inner wall of the fixed valve pipe correspondingly to the cold/hot water openings and the width of said inner groove is equal to or bigger than that of the cold/hot water openings. The structure allows scale to be removed from the balance valve and service life extended.
