How to classify pneumatic joints according to their structure

Date:19-11-15

When the ferrule of the parent body moves to the other end, the stainless steel ball of the pneumatic joint 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.

Pneumatic joints can be divided into:
1. Open close type at both ends:
When the pneumatic joint is 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 disconnected due to the operation of the valve spring force of the parent body and the sub body, and the valves of the sub body and the parent body are closed respectively, blocking the flow of fluid instantly.

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 type at both ends
No connection - when the ferrule of the parent body is pushed to the other end, the ball of the pneumatic joint automatically rolls outward, so the sub body is removed; because there is no valve between the sub body and the parent body, 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 opening and closing
When not connected - when the ferrule of the parent body moves to the other end, the stainless steel ball of the pneumatic joint 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.
