  • Publication number: 20210207852
    Abstract: Disclosed are a self-pressure-relief air distribution mechanism and a corresponding cryogenic refrigerator. The self-pressure-relief air distribution mechanism includes an air distribution valve (6) and a rotary valve (7), where a rear face of the air distribution valve (6) is divided into a high-pressure face (66) and a low-pressure face (65), and the high-pressure face (66) and the low-pressure face (65) are hermetically separated by a third sealing ring (b3) that seals the air distribution valve (6) and a cover (2); and the air distribution valve (6) is provided with a pressure-relief hole (61) that axially penetrates an air distribution face (64) and the low-pressure face (65) of the air distribution valve (6), and a low-pressure passage (22) of the cover (2) can communicate with the rear face of the air distribution valve (6) via the pressure-relief hole (61), to guide a low-pressure airflow in the cover (2) to the rear face of the air distribution valve (6).

  • Patent number: 9752824
    Abstract: A low-temperature device for separating and purifying gas based on a small-sized low-temperature refrigerating machine includes a primary, secondary and quaternary heat exchanger, at least one small-sized low-temperature refrigerating machine, and at least one liquid collecting tank. The small-sized low-temperature refrigerating machine includes a first cold head and a second cold head, the secondary heat exchanger is provided on the first cold head to form a primary cold head heat exchanger, the quaternary heat exchanger is provided on the second cold head to form a secondary cold head heat exchanger, a mixed gas outlet is connected to an inlet of the primary cold head heat exchanger. By using primary and secondary cold heads of the small-sized low-temperature refrigerating machine as cold sources, gases having different condensing temperature are liquefied and solidified separately, and two or more gases can be separated and purified at a lower cost.
