Description
Technical field
The invention belongs to ball valve core processing technology fields, particularly relate to a kind of suitable for the compound ball of ceramet
The processing method of valve core.
Background technology
Ball valve is a kind of valve being widely used in the industries such as petrochemical industry metallurgy power generation, but in some serious works of abrasion
Under the conditions of condition, ordinary ball valve is just difficult to meet the requirement at scene.Therefore, ceramic ball valve is just answered pregnant and is given birth in recent years.Ceramics
It uses engineering ceramic material sphere and valve seat to ball valve, since engineering ceramic material has hardness high wear resistance, corrosion resistant
Outstanding advantages, thus corrosivity is strong, under working condition of quick abrasion ceramic ball valve using effect than other materials valve
Want better.Although engineering ceramic material has the anti abrasive outstanding advantages of hardness highly corrosion resistant, it belongs to brittleness material after all
The ability that material, shock resistance and resistance to stress are concentrated is relatively poor；When the medium of conveying is air-liquid body, slag containing granule materials
When slurry, granule materials in medium can inevitably enter the sealing pair of valve, and controlled valve is just when slag inclusion occurs in sealing pair
Need increase switch strength, at this moment since the poor toughness of the ball for ball valve of ceramic material is frangible, it is easy to make sphere and
The ceramics damage of shaft connecting portion, even results in the damage of entire spheres of ceramic sometimes.Spheres of ceramic in use
Damage has become the widely used most important restraining factors of ceramic ball valve.The failure mode of ceramic ball valve including import
Mostly it is thus caused.
Invention content
The purpose of the present invention exactly provides a kind of multiple suitable for ceramet in view of the deficiencies of the prior art mentioned above
The processing method of mould assembly ball valve core.
The purpose of the present invention can be achieved through the following technical solutions：
The processing method of the compound ball valve core of ceramet of the present invention includes the following steps：
A, metallic framework and its rotation axis are processed；
B, the location hole coaxial with metallic framework rotation axis, support are processed respectively on two boss of metallic framework
Hole, and slotted hole is processed in location hole；
C, by the metallic framework processed in step b it is compound into spheres of ceramic, then utilize on two boss in advance plus
Sphere is fixed on lathe by location hole that work goes out, supported hole；
D, spool rotates under the drive of machine tool chief axis, using rotation axis with sphere rotation axis perpendicular to and at same
The tubbiness skive of one horizontal plane carries out rotary grinding to spheres of ceramic, and is gradually promoted to sphere axis direction, processing
Go out the spheres of ceramic of required size, shape.
Further, supported hole of the present invention is center hole or the endoporus for installing sliding bearing.
The principle of the present invention is：Metallic framework is mounted in spheres of ceramic by the present invention, and there are two stretch this metallic framework
To the boss of spherome surface.When work medium generate pressure and sphere rotate when by shaft generate torque all by sphere this
A metal parts is born, and erosion resistant position plays the corrosion resistant advantage of ceramic material hardness high wear resistance.Well known, ball valve makes
With when drive sphere rotation axis axis need it is consistent with the axis of sphere, if it is inconsistent will produce switch it is unsmooth,
It will appear stuck or even damage when serious.Common metal sphere first processes spherical surface, is then set by setting-out, tooling, finishing
Ceramic hardness unlike the standby axis for reprocessing out rotation and metal ball is too high, in addition to plane facilitates finishing, it is difficult to pass through
The above method ensures that the axis of rotary shaft is consistent with the axis of sphere.To solve the practical difficulty encountered in this practical manufacturing process
Topic, in the metallic framework insertion spheres of ceramic with two boss before with rotary shaft coupling part or process the ceramics
Technique needed for sphere spherical surface（Cone）Hole machines in advance.
The beneficial effects of the invention are as follows：
The reality for the spheres of ceramic itself that the processing method of the compound ball valve core of ceramet of the present invention is processed
Axis and rotation axis are identical, and such valve will be very smooth during actual switch, the using effect of valve,
Sealing effect and service life will greatly improve.

Specific implementation mode
The present invention is described further below with reference to embodiment.
The processing method of the compound ball valve core of ceramet of the present invention of the present invention includes the following steps：
A, metallic framework and its rotation axis are processed；
B, the location hole coaxial with metallic framework rotation axis, support are processed respectively on two boss of metallic framework
Hole, and slotted hole is processed in location hole；
C, by the metallic framework processed in step b it is compound into spheres of ceramic, then utilize on two boss in advance plus
Sphere is fixed on lathe by location hole that work goes out, supported hole；
D, spool rotates under the drive of machine tool chief axis, using rotation axis with sphere rotation axis perpendicular to and at same
The tubbiness skive of one horizontal plane carries out rotary grinding to spheres of ceramic, and is gradually promoted to sphere axis direction, processing
Go out the spheres of ceramic of required size, shape.
Further, supported hole of the present invention is center hole or the endoporus for installing sliding bearing.
Specifically, as shown in Figs. 1-3：Processed on a boss of metallic framework be connected with shaft with oval
The location hole in hole；Center hole on the same axis is processed on another boss, if it is float ball, is then added on the boss
Work goes out to install the endoporus of sliding bearing.
As illustrated in figures 4-5：That there are two the metallic frameworks of boss is compound into after in spheres of ceramic for band, using on two boss
Sphere is fixed on lathe by location hole, the supported hole processed in advance, is rotated around X-axis under the drive of driving shaft；
Rotated around Y-axis in the tubbiness skive of same level with special, rotation axis and sphere rotation axis and gradually to
Sphere axis direction promotes, and spherical surface can process, and when processing also can exist grinding wheel to scheme central axes intersection point as the center of circle
It is rotated on horizontal plane.
