Abstract
The present invention relates to a liquid sealing device which is made of glass and is used for chemical water free and oxygen free experiments. In the present invention, at least one one-way piston valve which can make gas flow out of the device is arranged in a pipe connected with a reaction system or a pipe communicated with the environment. Due to the arrangement of the one-way piston valve, when the system is pumped into vacuum, the one-way valve is in a closed state under the action of negative pressure of the system to isolate the reaction system from the outside. After the vacuum operation is completed, the one-way piston valve is still in a closed state when the system is still in a negative pressure state in the process of filling in inactive gas, but after the system is in a positive pressure state, the valve is opened.
