I believe everyone is familiar with the quick connector. Its existence greatly simplifies our life. Let us briefly introduce the two connection methods of the quick connector:
1. One-way open and close. When it is not connected, when the ferrule of the parent body is moved to the other side, the beads of the stainless steel quick connector will roll out on their own, and the child body will be bounced off by the reaction effect of its spring, and it can turn off the blocking by itself. its flow. When connected, when the child is inserted into the parent side where the ferrule is present, it is opened to allow it to flow, the washer is pushed back to the starting position by the effect of the spring, and its beads lock to ensure the child/parent connection. , the gasket inside can completely block its leakage.
2. Both ends are open. When it is not connected, when the ferrule of the parent body is pushed to the other side, it will roll out on its own, so the child body is removed; because the child body and the parent body do not exist, they will move toward the outflow. Connection, when the daughter body is inserted into the mother body, it will be pushed to the original place by the effect of the spring to lock the steel ball, and the O-ring is used to prevent liquid leakage.
