Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for processing pneumatic butterfly valves. Background Art

[0002] The pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to open and close to achieve the activation action. It is mainly used as a shut-off valve. The inner ring of the pneumatic butterfly valve needs to ensure the processing quality to achieve the contact accuracy with the sealing ring. If the inner ring is too rough, the wear of the rubber sealing ring will accelerate.
