The electrolyte needs to be packaged and stored in a stainless steel tank body in the transportation process, a battery manufacturer needs to draw the electrolyte out of a packaging barrel when in use, in order to realize quick and efficient production operation, two or more quick connector male bodies are usually installed at the upper end of the packaging barrel, and one quick connector parent body is installed at one end of a battery production line; when the device is used, a quick connector at the upper end of the packaging barrel is connected with an air source, compressed air is input, certain pressure exists in the tank, a quick connector matrix on a battery filling line is connected with a quick connector male body on the packaging tank, the storage tank forms a passage with a pipeline on a canning production line, and electrolyte in the tank flows to all stations on the production line from the tank through the quick connector along the pipeline under the action of air pressure. When the quick connector is not used, the male body and the female body of the quick connector are separated, and at the moment, the valve core in the quick connector can close the pipeline under the action of the spring, so that liquid cannot flow out. If the valve core is blocked by impurities at this time, the valve core is not tightly sealed, liquid leakage accidents can occur, and the leakage is a major accident as the electrolyte is expensive and has strong corrosivity. Thus, the use safety requirement in the whole transportation and use process is high. In the use process, once impurities flow through the valve core of the quick connector, the impurities are easily attached to the sealing gasket, the valve core is not closed tightly, leakage accidents are caused, and the service life of the connector is shortened.
