Detailed description of the invention
As shown in Figure 1, the utility model comprises laboratory desiccators 11, vacuum pump using circulatory water 1, three-way valve 10 and inert gas air supply system, described inert gas air supply system comprises inert gas steel cylinder 2, gas drying tube 8 and gas rotameter 9, the gas outlet of described inert gas steel cylinder 2 is communicated with the air inlet of gas drying tube 8 by the first pipeline 4, the gas outlet of described gas drying tube 8 is communicated with the air inlet of gas rotameter 9 by second pipe 5, the gas outlet of described gas rotameter 9 is by the inlet communication of the 3rd pipeline 6 with three-way valve 10, the outlet of described three-way valve 10 is communicated with the bleeding point of laboratory desiccators 11 by the 5th pipeline 7, the commutation mouth of described three-way valve 10 is communicated with the bleeding point of vacuum pump using circulatory water 1 by the 4th pipeline 3.
In the present embodiment, described first pipeline 4, second pipe 5, the 3rd pipeline 6, the 4th pipeline 3 and the 5th pipeline 7 are rubber tube, not only can meet the demand passing into low pressure of inert gas power, and handled easily.
In the present embodiment, described gas drying tube 8 is lucite drying tube, is convenient to observe.
