Claims

1. A precision ceramic valve with two inlets and two outlets, comprising a rotating seat within a valve housing, and below the rotating seat, within the valve housing, a slider, a baffle, a movable valve plate, and a fixed valve plate stacked sequentially. A valve stem extending upwards through the valve housing is centrally mounted on the rotating seat, with its bottom actuating portion engaging with the slider. The slider and the rotating seat are respectively connected to the baffle and the movable valve plate. Operation of the valve stem, via the slider, causes the baffle to move horizontally, or after horizontal movement, the movable valve plate rotates via the rotating seat. The change in the alignment between the movable valve plate and the fixed valve plate after movement allows for the opening and closing of the water supply, or the alteration of the mixing ratio of hot and cold water and the flow rate. Below, a base is used to prevent the fixed valve plate, the movable valve plate, the baffle, the slider, and the rotating seat from falling out. The base has a water inlet chamber, in which a balancing valve is installed. The precision ceramic valve is placed in a pre-reserved valve chamber in a water distribution valve seat during use. This water distribution valve seat has a cold water inlet channel, a hot water inlet channel, a first outlet channel, and a second outlet channel extending outwards from the bottom of the valve chamber. The cold water inlet channel and the hot water inlet channel are used to connect to cold and hot water sources, respectively. The first outlet channel and the second outlet channel are respectively connected to a water-using device. Thus, by operating the same precision ceramic valve, cold water, hot water, or a mixture of hot and cold water can be delivered to one of the water-using devices via the water distribution valve seat. The feature is: The valve housing has an internal chamber, and an upper port is formed above it through a narrowed annular wall. The rotating seat, the slider, the baffle, the movable valve plate, and the fixed valve plate are sequentially placed into the chamber of the valve housing. The upper port is used to allow the valve stem to pass through the valve housing upward. A groove is formed at the bottom of the baffle, and a first hole and a second hole are passed through the movable valve plate. Under normal conditions when not in use, the groove of the baffle will avoid the first hole, so as to achieve the water shut-off effect that neither cold nor hot water sources can be diverted out. The fixed valve plate has a cold water flow hole, two hot water flow holes, a first water outlet hole, and a second water outlet hole. The two hot water flow holes are interconnected, allowing the cold water flow hole to be located between the two hot water flow holes on one side. The first water outlet hole and the second water outlet hole are located on the other side of the two hot water flow holes. When the fixed valve plate and the movable valve plate are stacked and in the water-off position, the cold water flow hole will be aligned with the first hole, while the two hot water flow holes, the first water outlet hole, and the second water outlet hole will avoid the first hole and the second hole, so that both the cold and hot water sources can be effectively blocked and cannot flow out from the precision ceramic valve through the water distribution valve seat. The base is provided with a cold water inlet, a hot water inlet, a first outlet, and a second outlet, and has a reserved inlet chamber. The cold water inlet and the hot water inlet are connected to the inlet chamber. When the rotating seat, the slider, the baffle, the movable valve plate, and the fixed valve plate, which are housed in the inlet chamber, are stacked in sequence, the fixed valve plate, the movable valve plate, the baffle, the slider, and the rotating seat are supported by the base through the valve housing. In addition to ensuring that the fixed valve plate is secured on the base, it can also... The cold water inlet, hot water inlet, first outlet, and second outlet of the base are aligned with the cold water flow hole, hot water flow hole, first outlet through hole, and second outlet through hole of the fixed valve plate, respectively. When the precision ceramic valve is placed in the valve chamber reserved in the water distribution valve seat, the cold water inlet, hot water inlet, first outlet, and second outlet are connected to the cold water inlet, hot water inlet, first outlet, and second outlet of the base, respectively.

2. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, A limiting block protrudes from one side of the upper port. A neck is formed on the rotary seat with a narrowed diameter. The neck extends out from the upper port and has a toothed edge on its outer periphery. By using the extension of the neck, two toothed rings can be provided by the toothed edge to be locked after being fitted. By removing the two toothed rings upwards and refitting, the temperature limiting angle can be adjusted according to actual usage requirements.

3. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The bottom end of the rotating seat is provided with a channel to accommodate the slider and the baffle, so that the slider and the baffle can be moved horizontally by the valve rod in the channel.

4. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The first hole and the second hole of the movable valve plate each have an outward expansion portion formed on one side of the hole edge. The outward expansion portion is recessed from bottom to top, which can be used to increase the coverage area of ​​the first hole and the second hole.

5. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The bottom surface of the fixed valve plate is recessed with a flow channel, allowing the two hot water flow holes to be connected through the flow channel.

6. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The base is formed by the upper seat and the lower seat being joined together, so that the cold water inlet, the hot water inlet, the first water outlet and the second water outlet can all be set at the relative positions of the upper seat and the lower seat at the same time, and the upper seat and the lower seat will be solidified by ultrasonic welding after being joined together.

7. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The precision ceramic valve utilizes an adapter to allow for the installation of a check valve within the valve chamber of the water distribution valve seat. The adapter includes a cold water inlet, a hot water inlet, a first outlet, and a second outlet, enabling interconnection between the base and the water distribution valve seat through these connections. A check valve is placed in both the cold water inlet and the hot water inlet, thus preventing backflow of water.

8. The precision ceramic valve with two inlets and two outlets according to claim 7, characterized in that, The adapter is formed by the mating of an upper adapter and a lower adapter, so that the cold water inlet, the hot water inlet, the first outlet, and the second outlet of the adapter can all be located at the relative positions of the upper and lower adapters. After the upper and lower adapters are mated, they will be solidified by ultrasonic welding.

9. The precision ceramic valve with two inlets and two outlets according to claim 1, characterized in that, The water distribution valve seat is embedded in the wall, and the first water outlet is used to connect one of the water-using devices downwards, while the second water outlet is used to connect another water-using device upwards.

10. The precision ceramic valve with two inlets and two outlets according to claim 9, characterized in that, One of the water-using devices is a water tap, while the other is a wall-mounted shower head.
