Description

Technical Field

[0001] The utility model relates to the field of valve core processing, in particular to a valve core grinding device for a feed valve. Background Art

[0002] The feed valve is usually composed of a valve body, a valve cover, a valve core, an actuator and other components, and the valve core plays a vital role in it. By adjusting the opening of the valve core, the pressure of the fluid can be controlled to adapt it to different working conditions. The movement of the valve core can also adjust the amount of fluid flowing through the valve, thereby achieving precise control of the flow rate. A grinding device will be used for grinding during the processing of the valve core.

[0003] However, in the prior art, a large amount of waste dust is generated when the grinding device grinds the valve core. Such waste dust accumulates on the valve core and the placement seat, making it difficult to clean up. Utility Model Content
