Description
Technical field
The invention belongs to ball for ball valve grinding technology fields, and ball for ball valve attrition process is used for more particularly to one kind
Grinder.
Background technology
Ball valve (ball valve), the valve that opening and closing element (sphere) is driven by valve rod, and rotated around ball valve axis.
Also it can be used for the adjusting and control of fluid.Ball valve is mainly characterized by that itself is compact-sized, is suitable for water, solvent, acid and natural
The general works medium such as gas, but also the medium severe suitable for operating condition, such as oxygen, hydrogen peroxide, methane and ethylene.
Suitable for often operating, open and close rapid, light.Fluid resistance is small.Simple in structure, relative volume is small, light-weight, easy to repair.
Good seal performance is not limited by installation direction, and the flow direction of medium can be arbitrary.Pressure control opening and closing element of the sphere as ball valve, belongs to pass
Key part, processing grinding are always the key points and difficulties in ball valve production.To hard seal ball valve, the spray welding process and coating of sphere
Technique requires higher for the roughness and circularity of sphere.Current sphere abrading-ball technique is mostly artificial abrading-ball or semi-automatic mill
Ball, first, cost of labor increases at this stage, due to gradually showing for domestic aging society, there is asking with no people in factory
Topic, urgent need go to substitute manually to complete this kind of repetitive operation with machinery；Second, abrading-ball does not have fixed visualization utensil to survey
Amount, by artificial personal assurance, the case where finally detecting whether qualification by measuring appliance, often will produce abrading-ball repeatedly；Third, people
Work abrading-ball has inhomogeneities generation, and the abrading-ball master worker to lack experience can cause sphere circularity insufficient, and it is big that the later stage repairs difficulty.
Ball valve is widely used in industries such as oil, chemical industry and city central heatings.When conveying high temperature or in micro-
When fine granularity medium, hard seal ball valve is generally selected.Opening and closing element of the sphere as ball valve forms a pair of of sealing with valve seat
Pair is assemblied in the valve body of ball valve, and the spherical surface and valve seat of sphere are in contact, and is played by rotating sphere and is opened and closed ball valve
Function.Required precision is very high during manufacturing for the spherical surface of sphere, needs to be ground after roughing, reaches higher by grinding
Precision and suitability with valve seat.Ensure that hard seal ball valve reaches good sealing, depends on the circularity of sphere spherical surface and thick
Rugosity.The sphere grinder bore that can be bought on domestic market is smaller, to increase bore, then expensive.Inlet ball
Body grinder involves great expense, and maintenance cost is higher.Traditional hand lapping mode is such as used, low production efficiency, operation labour is by force
It spends larger.In order to meet the processing request of different bore ball body of valve spherical surfaces, to existing equipment carry out analysis repeatedly, demonstration and
Test, develops hard-seal ball valve body grinding machine.
