A ceramic valve includes a casing, a drive seat, a coupling seat, a rotary block and a fixed block sequentially mounted into the casing, wherein a braking shaft is pivotally connected to the drive seat and extends through a top of the casing. A pedestal is sealingly secured on a bottom of the casing for positioning the drive seat, the coupling seat, the rotary block and the fixed block. The rotary block is moved relative to the fixed block to guide cold water into the ceramic valve when the ceramic valve is in a middle section and the braking rod is operated to an inclined status. |

1. A ceramic valve apparatus comprising:
a hollow casing with a protrusion extending therefrom, said protrusion having a top opening at a distal end of said hollow casing, said hollow casing having a bottom opening at a bottom thereof; a drive seat having a lower plate with a tubular position extending upwardly therefrom, said lower plate abutting a lower end of said protrusion, said tubular protrusion rotatably received in said protrusion, said drive seat having a cavity in a center thereof; a braking rod pivotally connected by a pin to said tubular portion of said drives seat, said braking rod having a toggle and extending through said drive seat, said braking rod having a trigger formed at a top end thereof, said trigger extending upwardly through said drive seat; a coupling seat receiving said toggle end of said braking rod; a pedestal secured in said bottom opening of said hollow casing, said pedestal having a cold water inlet and a hot water inlet and an outlet, said cold water inlet adapted to guide cold water into the ceramic valve apparatus, said hot water inlet adapted to guide hot water into the ceramic valve apparatus, said outlet adapted to allow a mixture of the hot and cold water to flow outwardly of the ceramic valve apparatus; a fixed block securely and sealingly disposed on a top of said pedestal, said fixed block having a first through hole communicating with said cold water inlet and a second through hole communicating with said hot water inlet and a third through hole communicating with said outlet; a rotary block rotatably disposed on said fixed block, said rotary block having a tunnel defined therein, said tunnel selectively communicating with said first through hole and said second through hole and said third through hole when said rotary block is rotated relative to said fixed block; a coupling seat disposed between said rotating block and said lower plate of said drive seat, said coupling seat synchronously rotating with the rotary of said rotary block, said coupling seat having a trough defined in a top face thereof, said trough receiving said toggle end of said braking rod, said coupling unit having an indentation in a top face thereof; and a fulcrum unit having a flanged protrusion extending downwardly therefrom from an edge thereof, said flanged protrusion being received in said indentation of said coupling seat. |
