[0032] In addition, the quantitative pump 4 adopts a quantitative pump suitable for low-temperature environment, preferably an AMC chemical standard magnetic pump suitable for low-temperature environment, such as an AMC chemical standard magnetic pump produced by Oulank Pump Industry.

[0033] The low-temperature high-pressure liquid is stored in the low-temperature liquid supply bottle 1. In order to reduce the heat leakage, the total liquid supply pipeline 2, the first branch liquid supply pipeline 6, the second branch liquid supply pipeline 7, and the liquid supplement pipeline 13 all adopt vacuum pipes with vacuum interlayers composed of an inner pipe and an outer pipe.

[0034] In view of the vibration and pipeline strength problems, as shown in Figure 2 and Figure 3 , the scheme is provided with a plurality of support rings 15 in the vacuum interlayer of the vacuum pipe. The support ring 15 is composed of an inner ring 151 sleeved on the inner pipe and a plurality of support arms 152 arranged on the outer circumferential surface of the inner ring 151. Each support arm 152 is uniformly and circumferentially spaced on the outer circumferential surface of the inner ring 151, and each support arm 152 is supported in the space between the inner ring 151 and the outer pipe.
