Structure classification and function of pipeline quick coupling

Pipeline quick connector is a kind of connector that can realize pipeline connection or disconnection without tools. The pipeline quick connector includes a female connector body with a through hole in which a steel ball is embedded; on one side is a male connector cylinder with a groove on the surface of the column body and a ferrule; the female connector body follows the male The joint cylinder tightly fits, and the steel ball in the mother body is caught in the groove on the surface of the cylinder body; the ferrule is to be sleeved on the outer surface of the female connector body, which is characterized in that it also includes a pull sleeve which is arranged on the male The connector cylinder is on the surface, and its internal thread is connected with the ferrule on the female connector.

  Structure classification of pipeline quick coupling

 

1. Opening and closing at both ends

When not linking: When the ferrule of the mother body moves to the other end, the stainless steel ball rolls outward automatically, the child body is disconnected under the action of the 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 , Instantaneously blocking 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, the steel ball rolls to lock the child body tightly connected, and at the same time, the valves of the mother body and the child body push each other to open, fluid circulation, O-ring Can completely block fluid leakage.

2. 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 removed; because neither the child body nor the mother body has a valve, the fluid flows out.

When linking: When the daughter body is inserted into the mother body, the ferrule is pushed to the previous position by the force of its spring to cause the steel ball to lock and the fluid flows, and the O-ring in it prevents liquid leakage.

3. One-way opening and closing

No link: 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 rebounded by the reaction force of the valve spring, and the valve can automatically close to block the flow of fluid.

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

 

The function of pipeline quick coupling

 

Exchange function: Air pressure, hydraulic tools, cylinders, hydraulic cylinders, 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 for vacuum, pressure resistance, leakage, operation, etc.

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

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

Connection function: fishing rods, fixed pieces of compact laser records, connection for mobile operations and other uses for fluid delivery.

The above is the relevant content about the quick coupling of pipeline introduced for everyone. What are the advantages of the quick connector? When the quick connector is used to disconnect and connect the oil circuit, the action is simple, saving time and labor. When the quick connector is broken and connected, the oil will not be spilled out, which is conducive to the protection of the environment.
