The high-speed electromagnetic valve is an actuating element on a plurality of electronic control components, and the high-speed opening and closing capacity of the high-speed electromagnetic valve determines the product performance of the actuating element. The high-speed electromagnetic valve controls the valve component to be opened and closed quickly through the electromagnet, so that the reciprocating frequency of the movable iron core of the electromagnet is extremely high, and the movable iron core of the electromagnet is frequently contacted and collided with a static valve body component. When the end face of the movable iron core is in collision contact with and attached to the end face of the valve body component, the end face of the movable iron core and the end face of the valve body component are inevitably adsorbed due to the existence of hydraulic pressure or air pressure, and therefore certain response delay phenomenon exists when the movable iron core moves reversely. Therefore, domestic and foreign enterprises begin to process grooves on the end face of the movable iron core or the end face of the valve body component, and a certain clearance space is always reserved between the end face of the movable iron core and the end face of the valve body component due to the existence of the grooves, so that oil or gas can conveniently enter the grooves to achieve pressure balance, and the response delay phenomenon is avoided.

However, when the high-speed electromagnetic valve is applied to a quick response environment, the collision frequency of the movable iron core of the high-speed electromagnet and the valve body component is extremely high, and the groove machined on the end face is quickly abraded and flattened under frequent collision impact, so that the structure fails, the response delay phenomenon occurs again, and the use effect of the actuating element is affected. Therefore, a high-speed electromagnet solving the above problems is desired, so that the response delay phenomenon of the high-speed electromagnet can be prevented for a long time, thereby improving the service life of the high-speed electromagnet.
