AI Technical Summary
Existing valves have difficulty maintaining the valve core at the expected throttling position in high-pressure fluid environments, and the gas flow is not easy to control precisely, resulting in a decrease in the controllability and reliability of the valve, especially posing safety hazards in low-flow regulation areas under high-pressure gas environments.
Design a valve core assembly including an axially extending valve core and a valve core sleeve sleeved outside it. The valve core sleeve has throttling sections and orifices with different inner diameters. Combined with a groove structure, it realizes balanced force and stable regulation of fluid flow. Equipped with an electromagnetic actuator and an electronic control unit, it realizes flexible control of the valve core.
It achieves stable and reliable adjustment of the valve core in high-pressure gas environments, improves the controllability and flexibility of the valve, adapts to a wide range of input pressure changes, and reduces the risk of gas leakage.
