A cryogenic distribution box or cryogenic valve box is arranged between the cryogenic system and the terminal equipment; whose function is to split the cryogenic liquid into various terminal devices through the integrated valves and cryogenic transfer line. The cryogenic distribution box is mainly composed of vacuum vessel, LN thermal shield, pipeline system, various regulating valves, heat exchanger, temperature, pressure, liquid level and other measurement and control electronics components.
The vacuum vessel provides high vacuum insulation for the internal cryogenic components. In order to reduce the radiation from room temperature to the cryogenic components, the LN thermal shield usually uses copper or aluminum plates with winding copper or aluminum pipe welded on the surface; The regulating valves adjust the opening positions according to the signals from sensors of the liquid level, pressure, temperature, to achieve the purpose of adjusting the relevant parameters of cryogenic liquid.
