Description

technical field [0001] The invention relates to the technical field of low temperature equipment testing, in particular to a heat leakage testing device and a method for using the same. Background technique [0002] Leakage heat refers to the heat transferred from the surrounding environment to the medium in the cryogenic equipment per unit time. For cryogenic valves, the leakage heat refers to the heat transferred from the surrounding environment to the operating medium in its flow channel through the cryogenic valve per unit time. In many existing engineering technologies, a large amount of cryogenic liquid is required to meet the needs of production and scientific research, and the cryogenic valve is a commonly used and important component in many cryogenic equipment, and its operating environment temperature is lower than normal temperature or far away. Lower than normal temperature, which requires cryogenic valves to be able to withstand the low temperature in the worki...
