Core Tip: Quick Coupler is a connector that allows the pipe to be connected or disconnected without the need for tools. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and quick connectors for semiconductors.

To explain to everyone, the quick connector can be divided into two types: open and close at both ends, open at both ends, and open and closed at one end.

1. Both ends are open and closed

When not linking: When the ferrule of the mother body is moved to the other end, the stainless steel beads automatically roll outward, and the child body is disconnected due to the action of the spring force of the mother and the child together, and the valves of the child body and the parent body are respectively closed. Instantly block fluid flow.

When linking: When the child body is inserted into the mother body, the ferrule returns to the original position under the action of the spring, the steel ball rolling locking body is tightly connected, and the valve of the mother body and the child body pushes each other to open, the fluid circulates, the O-ring Can completely block the leakage of fluid.

2, open ends

No link: When the ferrule of the parent body is pushed to the other end, the steel ball automatically rolls outward, so the child body is removed; since there is no valve between the child body and the mother body, the fluid flows out.

When linking: When the child body is inserted into the mother body, the ferrule is pushed to the previous position by the force of its spring, the steel ball is locked, the fluid flows, and the O-ring is used to prevent liquid leakage.

3, single way open and close

No link: When the ferrule of the parent body moves to the other end, the stainless steel beads automatically roll outward, and the child body is bounced off 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 body is inserted into the side of the parent body of the ferrule, the valve is opened to cause fluid to flow, the washer is pushed back to the original position by the force of the spring, the stainless steel beads are locked to ensure the connection of the child/parent, and the gasket inside can Completely block fluid leakage.
