Description

Technical Field

[0001] This utility model relates to the technical field of butterfly valve stem processing equipment, and more specifically, to a grinding device for processing butterfly valve stems. Background Technology

[0002] The butterfly valve stem is an important component of the butterfly valve, and a grinding machine is required when machining the butterfly valve stem.

[0003] A search revealed an existing device (CN215659565U) for grinding butterfly valve plates. The device includes a housing, an upper connecting rod slidably connected to the top of the housing along a vertical direction, an upper pressure plate rotatably connected to the bottom of the upper connecting rod, a lower rotating column rotatably connected to the bottom of the housing below the upper pressure plate, a lower top plate fixedly connected to the top of the lower rotating column, a fixed column fixedly connected to the bottom of the housing near the lower rotating column, a limit column rotatably connected to the top of the fixed column, a connecting rod fixedly connected to the top of the limit column, and a limit plate fixedly connected to the bottom of the connecting rod. This invention, by having an upper connecting rod slidably connected to the top of the housing along a vertical direction, and an upper pressure plate rotatably connected to the bottom of the upper connecting rod, reliably clamps butterfly valve plates of different thicknesses under the action of a compression spring, thus avoiding the situation where the operator's hands are holding the butterfly valve plate.

[0004] The high-speed friction between the grinding wheel and the butterfly valve stem in the grinding machine used for butterfly valve stem processing can easily lead to the generation and accumulation of static electricity in the working area. This static electricity is difficult to eliminate and poses a safety hazard. Therefore, we have proposed a grinding device for butterfly valve stem processing to solve the above-mentioned problems.
