[0028] Embodiment 2

[0029] On the basis of Embodiment 1, a preferred embodiment of a gas charging and discharging device for a vacuum environment provided by the present utility model is as follows Figures 1-4 As shown in the figure: A high-vacuum ball valve 13 is arranged on the right side of the six-way pipe 1. An O-ring seal one 14 is fixedly installed at the right end of the six-way pipe 1. A hexagon socket head bolt one 15 is fixedly installed between the six-way pipe 1 and the high-vacuum ball valve 13 by means of threads. A diaphragm valve 16 is arranged at the bottom of the fixing frame 10. A hexagon socket head bolt two 17 is arranged at the top of the diaphragm valve 16. A high-vacuum fine adjustment valve 18 is arranged at the top end of the needle valve connecting pipe one 2. The high-vacuum fine adjustment valve 18 and the needle valve connecting pipe one 2 are fixedly installed by means of threads through the hexagon socket head bolt two 17.
