This application discloses a charging valve structure for a Stirling refrigerator and a Stirling refrigerator, relating to
refrigeration technology. The valve includes: a main valve body with an axially extending mounting cavity, a first interface for connecting to an external air source, and a second interface for connecting to the charging port of the Stirling refrigerator; an adjusting component disposed within the mounting cavity of the main valve body, the adjusting component being rotatable within the mounting cavity and slidable axially along the mounting cavity, one end of the adjusting component having a valve head for controlling the connection / disconnection between the charging port and the first interface; the adjusting component includes a first rotating member and a second rotating member arranged sequentially along the axial direction. The charging valve of this application features small size, ease of operation, easy replacement, and good sealing performance, effectively solving many technical problems caused by existing charging valves and improving process production efficiency.
