What is a pneumatic joint? How should it be applied in practice?

The pneumatic joint is a quick joint mainly used for air piping and pneumatic tools. It can connect or disconnect pipes without tools.

When the ferrule of the mother body moves to the other end, the stainless steel beads automatically roll outward, and the child body is disconnected due to the action of the valve spring force of the mother body and the child body. Fluid flow.

The movable joint has three structures:

1. Opening and closing at both ends:

When linking-when the child's body is inserted into the mother's body, the ferrule returns to its original position under the action of the spring, and the steel ball rolls to lock the child's body tightly connected. At the same time, the valve of the mother body and the font push each other to open, fluid flow, O-ring Can completely block fluid leakage.

2. Open ends

When not linked: When the ferrule of the mother body is pushed to the other end, the steel ball automatically rolls outward, so the child's body is removed; because there is no valve on the font and the mother body, the fluid flows out.

Link: When the child's body is inserted into the mother's body, the ferrule is pushed to the previous position by the force of its spring, causing the steel ball to lock, the fluid flows, and the O-ring in it prevents liquid leakage

3. Single open and closed

When not linked: When the ferrule of the mother body moves to the other end, the stainless steel beads automatically roll outward, and the daughter body is opened by the reaction force of the valve spring, and the valve can be automatically closed to block the fluid flow.

When linking: When the child is inserted into the mother side of the ferrule, the valve is opened to cause fluid flow, the gasket is pushed back to its original position by the force of the spring, and the stainless steel beads will lock to ensure the child/parent connection. The gasket inside can Completely block fluid leakage
