Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of ceramic seal ball valve.
Background technique
Existing industrial ball valve, all adopt Stainless Steel Ball, plastic cement ball, Furtulon seal ring as sealing material, because the surface of these materials is not wear-resisting, the gap of this ball valve sealing is variable big after using for a long time, after ball valve runs into high temperature, easily produce the different expansivity of sealing surface again and be difficult to sealing, directly have influence on the quality and the life-span of its use; Moreover these materials also can't be evaded various acrid liquids and seal the destruction that it produces, and cause being difficult to seal and the easy problem that leakage takes place.For addressing this problem, adopted ceramic valve ball now, effect obtains very big improvement.But the rigidity of pottery is littler than the metal, in the operating lever rotary course, directly drives ceramic valve ball rotation by the operating lever lower end.The This move process is too direct, and the folding of valve is very fast, and ceramic valve ball force bearing point is very little, is easy to damage because of local pressure is excessive ceramic valve ball.
Summary of the invention
The purpose of this utility model provides and a kind ofly is provided with ferrule piece in ceramic valve ball inside, is driven the ceramic seal ball valve of ceramic valve ball rotation by ferrule piece; It has solved directly stressed rapid rotation of ceramic valve ball in the existing ceramic seal ball valve rotary course, the technical deficiency that force bearing point is little.
For realizing that the technological scheme that the purpose of this utility model is taked is:
A kind of ceramic seal ball valve, comprise a valve seat shell, be provided with ceramic bearing and base in the valve seat shell, one ceramic valve ball is located in each ceramic bearing and the space that base enclosed, pottery valve ball top is provided with an openwork hole, and on the valve seat shell, be provided with operating lever, it is characterized in that: be provided with annular groove in ceramic valve ball, annular groove is embedded with a ring; The top of ring is provided with a swivelling chute, and swivelling chute is located in the openwork hole, and the rotating handle of operating lever below is located in the swivelling chute.
The longitudinal section of described annular groove be " in " font, cross section is rounded.
Described ring is a ferrule piece, the longitudinal section of ferrule piece be " in " font, cross section is rounded.
Described in annular groove, and be provided with a ceramic section of jurisdiction in the inboard of ferrule piece.
Described ferrule piece is assembled by some block assemblies.
Described ferrule piece is made up of the last assembly that comprises swivelling chute, left assembly, right assembly, following assembly; Left side assembly and right assembly symmetry.
The described two block assemblies part of joining is equipped with relative fluting.
Described ceramic section of jurisdiction is made up of four tubule sheets, about tubule chip architecture symmetry.
The beneficial effects of the utility model are: be provided with ferrule piece in ceramic valve ball inside, during rotation, directly not stressed, stress surface is big, and rotation lags behind, and ceramic valve ball is difficult for damaging, and prolongs ball valve working life; Ferrule piece is divided into four parts, is easy to be installed in after ceramic valve ball is fired its inside; Be provided with ceramic section of jurisdiction in the ferrule piece inboard, guarantee valve through hole good fluidity, wear-resisting, can reduce the corrosion of ferrule piece, prolong the life time of ferrule piece.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises a valve seat shell 1, is provided with ceramic bearing 2 and base 3, one ceramic valve balls 4 in the valve seat shell 1 and is located in the space that each ceramic bearing 2 and base 3 enclosed.Pottery valve ball 4 tops are provided with an openwork hole 5, and the top of ring is provided with a swivelling chute 9, and swivelling chute 9 is located in the openwork hole 5, and the rotating handle of operating lever 6 belows is located in the swivelling chute 9.Openwork hole 5 is circular, and the cross section middle part of swivelling chute 9 is square the two ends semicircular in shape.The upper surface of swivelling chute 9 is set as fixed mesa 10, is provided with the exit or entrance of a clitch 13 in the swivelling chute 9, is beneficial to the rotating handle of fitting operation handle 6.
In ceramic valve ball 4, be provided with annular groove 7, be embedded with a ferrule piece 12 at annular groove 7.The longitudinal section of annular groove 7 be " in " font, cross section rounded (when openwork hole 5 parts are not considered), annular groove 7 cross sections be perpendicular to water (flow) direction, and parallel with the running shaft of operating lever 6.The longitudinal section of ferrule piece 12 be " in " font, its cross section rounded (when openwork hole 5 parts are not considered).
As Fig. 4, Fig. 5, shown in Figure 6, ferrule piece 12 is made up of the last assembly that comprises swivelling chute 9, left assembly, right assembly, following assembly; Left side assembly and right assembly symmetry.The two block assemblies part of joining is equipped with relative fluting 11.In annular groove 7, and be provided with a ceramic section of jurisdiction 8 in the inboard of ferrule piece 12.The pottery section of jurisdiction 8 form by four tubule sheets, about tubule chip architecture symmetry.Abutted surface in last three block assemblies of ferrule piece 12 between per two is on the radius of ferrule piece 12 cross sections, and the abutted surface of following assembly and left assembly, right assembly straight down.The situation of the abutted surface of each little section of jurisdiction of pottery section of jurisdiction 8 is identical with ferrule piece 12.
Like this, drive ferrule piece 12 rotations when the swingle of operating lever 6 rotates, ferrule piece 12 drives ceramic valve ball 4 rotations, and the rotation of ceramic valve ball 4 is not directly to be driven by operating lever 6.
The corner angle that contact between annular groove 7 and the ferrule piece 12 all are circular arc.Such design both had been easy to both installation maintenances, and the steel toughness indirect drive of the time utilizing ferrule piece in motion can be because of the mutual application of force to the annular groove 7 of pottery yet, and local pressure is excessive and produce potsherd.
