The invention provides an automatic ventilation system. The automatic ventilation system comprises an automatic ventilation device, a reaction chamber, an air charging device and a vacuumizing device,wherein the automatic ventilation device comprises a three-way valve and an electronic timing device, a first valve port of the three-way valve is connected with the reaction chamber through a firstair pipe, a second valve port of the three-way valve is connected with the vacuumizing device through a second air pipe, a third valve port of the three-way valve is connected with the air charging device through a third air pipe, the electronic timing device is electrically connected with the three-way valve, and the electronic timing device is used for periodically controlling opening and closing of the first valve port, the second valve port and the third valve port of the three-way valve. According to the automatic ventilation system, the automatic ventilation device, the reaction chamber,the air charging device and the vacuumizing device can be connected together by adopting the three-way valve and the three air pipes, so that the structure of the automatic ventilation system is greatly simplified, the fault occurrence rate is reduced, and the stability of an experimental result is improved.
Description
technical field [0001] The invention belongs to the technical field of automatic ventilation, and in particular relates to an automatic ventilation system and an automatic ventilation device. Background technique [0002] In the process of chemical experiments, the oxygen-free gas atmosphere plays a vital role in the experimental products. In the process of vacuuming, it is generally necessary for the user to remove the oxygen after several rounds of pumping, filling inert gas or reactive gas. However, these operations all require manual operations by the user. However, manual operation is not only inefficient, the precision is not easy to control, and it will destroy the results of chemical reactions. [0003] At present, someone has adopted an automatic ventilation system, which uses multiple electromagnetic valves to control air extraction and inflation, etc., but such an automatic ventilation system has a complex structure, many pipelines, and a high failure rate, whic...
