The invention discloses a control console of a leakage detection sampling and lofting circulating system for testing a total leakage rate of a spacecraft. A cuboid case of the control console of the sampling and lofting circulating system consists of two parts, namely an upper cover and a lower bottom, wherein a circular groove for mounting a standard container is formed in the upper cover part; a sampling opening is formed in the side wall of the upper cover and is communicated with a sampling valve through a sampling fixture; the sampling valve and a lofting valve are opposite to each other at the upper cover part and are respectively communicated with the standard container; the sampling valve and the lofting valve are connected with a sample gas pump in the lower bottom part through a three-way joint; a standard gas pump and the sample gas pump are arranged on the bottom surface of the lower bottom part side by side and are respectively powered by a transformer; standard gas and sample gas pipeline connection inlet/outlets are formed in the outer side wall of the lower bottom part and are respectively communicated with the sample gas pump and the standard gas pump through pipelines.
