Structure classification

Open and close at both ends, open at both ends, single open and close

Open and close at both ends

When not connected: When the ferrule of the mother body moves to the other end, the stainless steel ball automatically rolls outward, the child body is disconnected by the action of the common valve spring force of the mother body and the child body, and the valves of the child body and the mother body are closed separately , Instantly block fluid flow.

When linking: When the child 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 child body tightly connected. At the same time, the valves of the mother body and the child body push each other to open, fluid flow, O-ring It can completely block the leakage of fluid.

Open at both ends

No link: When the ferrule of the mother body is pushed to the other end, the steel ball automatically rolls outward, so the child body is moved out; since neither the child body nor the mother body has a valve, 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 to lock the steel ball, and the fluid flows. The O-ring is used to prevent liquid leakage.

Single circuit opening and closing

No link: When the ferrule of the mother body moves to the other end, the stainless steel ball automatically rolls outward, and the child body is bounced by the reaction force of the valve spring, and the valve can be automatically closed to block fluid flow.

When connecting: When the child body is inserted into the mother body with the ferrule, the valve is opened to cause fluid to flow, and the washer is pushed back to its original position by the force of the spring. The stainless steel ball will lock to ensure the child/parent body connection. Completely block fluid leakage.

Features

Exchange function: air pressure, hydraulic tools, cylinders, hydraulic cylinders, and metal mold-related machinery attachments.

Maintenance function: maintenance of the cooling device of the computer and the oil cylinder of the die-casting machine.

Test function: test of vacuum, pressure resistance, leakage, operation, etc.

Conveying function: conveying, handling and conducting functions of solids such as bolts and nuts.

Filling function: inert gas, nitrogen, PG, carbonic acid.

Connection function: fixed parts for fishing rods, compact compact discs, connections for mobile operations, and uses other than fluid transportation.

Features

1. Time-saving and labor-saving: When the oil circuit is disconnected and connected through the quick connector, the action is simple, saving time and manpower.

2. Fuel saving: When the oil circuit is broken, the one-way valve on the quick connector can close the oil circuit so that the oil will not flow out and avoid the loss of oil and oil pressure.

3. Environmental protection: When the quick connector is broken and connected, the oil will not spill and protect the environment.

4. The equipment is divided into parts for easy transportation: large equipment or hydraulic tools that need to be easily carried can be transported after being disassembled with quick connectors, and then assembled and used after reaching the destination.
