The utility model discloses ceramic material's high rigidity, stand wear and tear, corrosion resistant advantage both can have been exert, and the poor breakable shortcoming of traditional ceramics spheroid case toughness can be overcome again. The utility model provides an arouse the inefficacy problem because of the double -layered sediment phenomenon between the sealed face in the use, lay a good foundation for using widely of ceramic ball valve.
Description
Technical field
The utility model relates to a kind of ball valve core be applicable in the industries such as oil, chemical industry, metallurgy, generating in conveyance conduit, is more specifically a kind of compound ball valve core of Ceramic metal consisted of embedded metal link in spheres of ceramic.
Background technique
The key of ball valve quality height is sealing pair, and sealing pair is by the spool 1 ' rotated together with valve shaft 2 ' and (shown in Fig. 1,2) of forming with the valve seat of the match conical surface or sphere.Ball valve can be divided into fixing ball valve and floating ball valve by the mounting type of ball valve core, and ball valve can be divided into O type, V-type, all-ball valve and semispherical valve by the shape of ball valve core, and ball valve can be divided into hard seal ball valve and soft seal (elastic packing) ball valve by the material of valve seat.Ball valve core many employings metallic material of conventional ball valve makes, but because metallic material is not corrosion-resistant, quick abrasion, so be not suitable for that corrosivity is strong, the working condition of quick abrasion.In recent years along with the utilization of engineering ceramic material on valve, ceramic ball valve arose at the historic moment.Ceramic ball valve is with engineering ceramic material ball valve core and valve seat.Because engineering ceramic material has hardness high wear resistance, corrosion resistant outstanding advantages, so be specially adapted to that corrosivity is strong, under the working condition of quick abrasion.But because engineering ceramic material belongs to brittle material, the ability that its shock resistance and resistance to stress are concentrated is relatively poor, so when containing granule materials in the medium (gas, liquid, slag slurry etc.) carried, there is slag inclusion phenomenon between the sealing surface that granule materials inevitably enters into ball valve sealing pair, when now carrying out ball valve switch operation, just need the strength strengthening switch; Meanwhile, due to the ball valve core poor toughness, fragile of ceramic material, cause the connection part of valve shaft and ball valve core very easily to damage, sometimes even bring the damage of whole ball valve core.For avoiding the damage of the ball valve core caused because of slag inclusion, also someone attempts spraying one deck high-abrasive material and the sealing pair that partners with the valve seat of ceramic material after processing grinding by the ball valve core of metallic material making, but its wear-resisting property and corrosion resistant performance are had a greatly reduced quality.In sum, the slag inclusion phenomenon in use in ceramic ball valve between ball valve core and the sealing surface of valve seat easily causes inefficacy, has become its widely used main restricting factor of restriction.
Summary of the invention
The purpose of this utility model provides a kind of just and is combined into the compound ball valve core of Ceramic metal by embedded metal link in spheres of ceramic for the deficiencies in the prior art part.The utility model both can play the high hardness of stupalith, wear-resistant, corrosion resistant advantage, can overcome again the shortcoming that traditional ceramics ball valve core poor toughness is frangible.The utility model solves in use and causes Problem of Failure, for promoting the use of of ceramic ball valve is laid a good foundation because of the slag inclusion phenomenon between sealing surface.
