Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valve core processing, in particular to a solenoid valve core abrasive flow deburring device. Background Art

[0002] The valve core of the solenoid valve refers to the core component that controls the opening and closing of the valve, which is usually made of magnetic materials. When the solenoid valve is energized, the movement of the valve core is controlled by generating a magnetic field, thereby achieving control of the fluid (such as gas or liquid). When the solenoid valve is in operation, if the movement of the valve core is stuck or leaks, it will lead to adverse consequences such as damage to the coupling, unstable oil control, and reduced service life. This requires the valve core to have a lower surface roughness and higher shape accuracy.

[0003] Burrs are easily generated during the production process of the solenoid valve core, so it is necessary to use manual handheld sandpaper to polish the solenoid valve core, which consumes a lot of manpower and material resources and requires a high level of technical skills of the workers.

Based on this, this solution provides a solenoid valve core abrasive flow deburring device to solve the above-mentioned problems. Utility Model Content
