According to the structure, it can be divided into:
1. Open and close type at both ends:
When not linked - when the ferrule of the parent body moves to the other end, the stainless steel ball will automatically roll outward, and the daughter body will be disconnected under the action of the common valve spring force of the parent body and the parent body, and the valve of the daughter body and the parent body will be closed respectively, and the fluid flow will be blocked instantly.
When connecting -- when the daughter body is inserted into the mother body, the ferrule returns to its original position under the action of the spring, and the steel ball rolls to lock the daughter body tightly. At the same time, the valve of the parent body and the daughter body push each other to open, and the fluid flows. The O-ring can completely block the leakage of the fluid.
2. Open end
No link - when the ferrule of the parent body is pushed to the other end, the ball automatically rolls outward, so the daughter body is moved out; because there is no valve between the daughter body and the parent body, the fluid flows out.
Link - when the daughter is inserted into the parent body, the ferrule is pushed to the previous position by the force of its spring, causing the ball to lock and the fluid to flow. The O-ring in the ring prevents fluid leakage
3. Single way open close type
When not linked - when the ferrule of the parent body moves to the other end, the stainless steel ball automatically rolls outward, and the daughter body is opened by the reaction force of the valve spring, and the valve can automatically close to block the flow of fluid.
When connecting - when the daughter body is inserted into the parent side with the ferrule, the valve is opened to cause fluid flow, and the gasket is pushed back to its original position by the force of the spring. The stainless steel ball will be locked to ensure the connection between the daughter and the mother body, and the gasket inside can completely block the leakage of the fluid.
