NOVELTY - The utility model model claims a multi-path valve core with coating graphene comprising a valve body, one side of the valve body is fixedly provided with an electromagnetic driving device, the inner wall of the electromagnetic driving device is fixedly provided with a driving device, the electromagnetic driving device is internally provided with a thread sleeve, one side of the thread sleeve is provided with a travel limit block the inner wall of the thread sleeve is slidingly provided with a reversing valve core, the reversing valve core close to the driving device is sleeved with a thread spring, the valve body close upper end two sides are fixedly provided with a secondary temperature flow oil supplementing valve, the valve body far away from the electromagnetic driving device side wall is fixedly provided with a manual hydraulic valve. The multi-path valve core of the utility model is coated with a layer of coating layer graphene the outer wall after hardening treatment and precision machining, coating thickness is accurately controlled, the coating and the valve core main body are attached by a certain strength, The invention can greatly reduce the sliding friction coefficient between the valve core and the valve body and improve the surface resistance so as to improve the strength of the valve core and the service life.
