Description

technical field [0001] The invention relates to a low-temperature valve performance testing system based on computer data collection. Background technique [0002] With the development of cryogenic technology, cryogenic fluids have been used more and more widely. For example, liquid nitrogen is widely used in industrial production, scientific research and even civilian use. Liquid hydrogen and liquid oxygen have shown significant advantages in the field of national defense as rocket propellants. . In addition, with the sharp increase in energy consumption in recent years, many countries including China have adopted or are considering using a large amount of natural gas as one of the main energy sources. In order to improve the efficiency of long-distance transportation of natural gas, it needs to be liquefied and transported to place of use. In all aspects of using cryogenic liquids, cryogenic valves are one of the indispensable components. However, since this type of val...
