摘要： An electronic expansion valve is provided, which includes a main valve cavity. A sleeve is fixed in the main valve cavity. A lower end part of the sleeve is supported by a valve seat, and the lower end part of the sleeve surrounds a main valve port. A valve core seat is axially movably arranged in the sleeve. A lower part of the valve needle component extends into the sleeve to open and close the valve core valve port. A circumferential side wall of the sleeve is provided with a first communicating hole close to the main valve port and a second communicating hole away from the main valve port. The structural design of the electronic expansion valve may prevent an excessive impact on a valve core seat caused by the refrigerant with high pressure when the refrigerant flows forward, thereby preventing the eccentricity of the valve core seat.

摘要： An electronic expansion valve is provided, wherein a piston component and a valve needle component are located at the same side of a valve core seat. When refrigerant flows forwards, the piston component closes the bypass through hole, the refrigerant flows to a side of the vertical connecting pipe via the valve core valve port, and the valve needle component moves in the axial direction to regulate an opening of the valve core valve port. When the refrigerant flows reversely, the piston component moves upwards in the axial direction to open the bypass through hole, and the refrigerant flows to a side of the transverse connecting pipe via the bypass through hole. The electronic expansion valve ensures that the valve needle component seals the valve core valve port easily in a high pressure state when the refrigerant flows forwards, and reduces axial and radial dimensions of the valve seat.
