Technical Field

[0001] The utility model relates to the technical field of refrigeration compressors, and more specifically, to a high-efficiency refrigeration compressor with a sealing device. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] At present, the connection between the external pipes on the output pipe of the refrigeration compressor is connected by a threaded connection, and a sealing tape is wrapped around the thread on the outer wall of the output pipe to achieve a sealing effect at the connection. However, due to the passage of time, the sealing tape ages, resulting in poor sealing of the connection, causing the refrigerated gas to leak, thereby affecting the refrigeration effect.

At this time, the annular convex ring on the sealing tube is tightly pressed against the annular groove on the external tube. At the same time, the annular plate on the sealing tube is just tightly pressed against the annular notch on the notch, thereby improving the sealing of the external tube and effectively avoiding gas leakage after refrigeration of the refrigeration compressor body, which affects the refrigeration effect.
