Description

Technical Field

[0001] The invention relates to the technical field of valve processing, and in particular to an inner cavity processing device for valve processing. Background Art

[0002] A valve is a device used to control the direction, pressure and flow of a fluid in a fluid system. It is a device that allows the medium in piping and equipment to flow or stop and control its flow. In order to prevent the fluid from causing excessive resistance during circulation, during the valve processing and production process, the inner cavity of the valve's flow pipe position is usually polished with a grinding wheel. In order to facilitate the processing of the valve's inner cavity, an inner cavity processing device is required.

[0003] As for the current traditional inner cavity processing device, it usually drives the grinding wheel to rotate through a motor to polish different positions by moving inside the valve. In order to ensure the contact between the grinding wheel and the valve, the motor shaft and the valve are in an eccentric state, resulting in the valve easily exerting impact on the motor shaft during the grinding process, which can easily cause damage to the motor. At the same time, the valve flow pipe is located at two places and is in a discontinuous state, resulting in the grinding wheel being unable to complete the grinding in one time. The valve needs to be reversed and re-clamped, making the processing process more complicated. Summary of the invention
