Pneumatic quick coupling
Pneumatic quick coupling is a kind of quick connector mainly used for air piping and pneumatic tools. It can realize the connection or disconnection of pipes without tools. When the ferrule of the parent body moves to the other end, the stainless steel ball will automatically roll outward. The sub body will be disconnected under the action of the common valve spring force of the parent body and the sub body, and the valves of the sub body and the parent body will be closed respectively, Block the flow of fluid instantly.
Quick coupling Type
According to the structure, it can be divided into:
1. Open close type at both ends:
When connecting – when the sub body is inserted into the parent body, the ferrule returns to the original position under the action of the spring, the steel ball rolling locks the sub body tightly, at the same time, the valves of the parent body and the sub body push each other to open, the fluid flows, and the O-ring can completely block the fluid leakage.
2. Open end
No link – when the ferrule of the parent is pushed to the other end, the ball automatically rolls outward, so the daughter is moved out; because there is no valve between the daughter and the parent, the fluid flows out.
Link – when the sub body is inserted into the parent body, the ferrule is pushed to the previous position by the force of its spring, which causes the ball to lock, and the fluid flows. The O-ring in the ferrule prevents fluid leakage
3. Single way open close type
When not connected – when the ferrule of the parent body moves to the other end, the stainless steel bead automatically rolls outward, the sub 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 sub body is inserted into the side of the parent body with a 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 bead is locked to ensure the sub / parent connection, and the gasket inside can completely block fluid leakage.
Purpose and features
The quick connector is suitable for the connection of air pressure pipeline, compressed air and nitrogen. The pipeline can be loaded and unloaded frequently, such as the operation of pneumatic tools in the assembly line. It can also be used in hydraulic machinery, chemistry, ship piping, etc.
Quick connector for air pipe, air compressor, grinder, air drill, impact wrench, pneumatic screwdriver and other pneumatic tools.
1. Please do not use it for purposes other than quick fluid connection.
2. Please do not use for fluids other than applicable fluids.
3. Please do not connect with the quick fluid connector made by other companies.
4. Do not exceed the maximum use pressure.
5. Do not use outside the use temperature range to prevent the sealing material from wearing or leaking.
6. Do not hit, bend, stretch artificially to prevent damage.
7. Do not use it in the place mixed with metal powder or sand dust to prevent poor work or leakage.
8. If there are sundries attached, it will cause poor work or leakage.
9. Do not remove the quick connect fitting.
