the first branch pipe is connected with a water seal valve;
the second branch pipe is connected with a needle tube for extracting liquid in the fermentation device to know the condition of the liquid, and a second switch valve for opening and closing is arranged on the second branch pipe.
When the fermentation sample is required to be extracted, the main pipeline of the sealing plug can be stretched into the fermentation device, then the first switch valve of the fermentation gas plug is closed, and the second switch valve is opened. And after the sampling is finished, the second switch valve is closed, the main pipeline is moved upwards until the main pipeline is not contacted with liquid, and the fermentation gas plug valve is opened to continue fermentation.

The second branch pipe can also be connected with a pressure monitor, a temperature monitor, a liquid level indicator and a gas component analyzer to detect the condition of the fermentation liquid in different time periods.
The first switch valve and the second switch valve are respectively arranged at the positions of 0.1 cm to 2cm away from the main pipeline of the first branch pipe and the second branch pipe. The first switch valve and the second switch valve are positioned close to each other, so that the probability that liquid is left on the pipe of the air valve can be reduced, and pollution is easy to cause.
And a silicone coating is arranged in the sealing plug. The silicone resin coating has good water resistance, has lower cost efficiency compared with a special fluorine-containing polymer coating or a nano-structure coating, and can effectively prevent errors or microbial pollution caused by the fact that a sample is left on the inner wall.
