For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of ceramic seal formula ball valve, comprise a valve seat shell, be located at ceramic bearing and the base in the valve seat shell and be positioned at described ceramic bearing and the ceramic valve ball in the space that base encloses, the top of described ceramic valve ball is provided with an openwork hole, described valve seat shell is provided with an operating lever, be provided with annular groove in the described ceramic valve ball, this annular groove is embedded with a ring; The top of described ring is provided with a swivelling chute, and swivelling chute is arranged in described openwork hole, and the rotating handle of operating lever below is located in the swivelling chute.
As the further improvement of the technical program, the longitudinal section of described annular groove be " in " font, cross section is rounded; Described ring is ferrule piece, the longitudinal section of ferrule piece be " in " font, cross section is rounded.
As the further improvement of the technical program, the inboard of described ferrule piece is provided with a ceramic section of jurisdiction; Described ceramic section of jurisdiction is made up of four tubule sheets, about tubule chip architecture symmetry.
As the further improvement of the technical program, described ferrule piece is made up of the last assembly that comprises described swivelling chute, left assembly, right assembly, following assembly; Described left assembly and right assembly symmetry.
As the further improvement of the technical program, the described two assemblies part of joining is equipped with relative fluting.
Compared with prior art, the utility model ceramic seal formula ball valve is provided with ferrule piece in ceramic valve ball inside, during rotation, the pottery valve ball is directly not stressed, and stress surface is big, and rotation lags behind, the pottery valve ball be difficult for to damage, and has guaranteed good sealing property, also prolongs ball valve working life.
