Understand the connection method of Quick Couplings

Many people don't understand the connection method of Quick Couplings, let's take a look at it together.

Quick Couplings

1. Single-circuit open-close type. When not connected, when the ferrule of the mother body is moved to the other side, the bead of the stainless steel Quick Couplings can roll outward on its own, and the child body is bounced by the reaction effect of the spring, and it can be closed and blocked by itself. Its flow.

When connecting, when the child body is inserted on the side of the mother body where the ferrule exists, it is opened to make it flow, the washer is pushed back to the starting place by the effect of the spring, and its beads will be locked to ensure the connection of the child/parent body , The gasket inside can completely block its leakage.

2. Open at both ends. When it is not connected, when the mother body’s ferrule is pushed to the other side, it will roll outward on its own, so the child body is moved out; because the child body and the mother body do not exist, it will move towards Outflow.

Connection, when the child body is inserted into the mother body, it will be pushed to the original place by the effect of the spring to lock the steel ball and flow, and the O-ring is used to prevent liquid leakage.

When the Quick Couplings is used for a period of time, it is easy to malfunction, such as falling off, leakage and other problems. Before using the quick connector, check the leakage. If it exists, stop using it and replace it with a new one. At the same time, confirm that the gas welding gun valve is closed before connecting. When using, insert the hose firmly into the bottom of the interface and fix it with a hose belt or nut. Avoid using cracked hoses to prevent leakage and falling off. If vibration or impact occurs during use, stop working immediately. Forced work will reduce the durability of the machine.

Quick couplings must not be used for purposes other than couplings, such as mixing with metal powder or sand dust, etc., which may cause failure to work or leakage. It should also be noted that when using this type of stainless steel joint, the maximum pressure limit should not be exceeded. The fluid used must be a clean fluid filtered by a filter without other impurities. When working, the temperature should be controlled within the use range of the quick coupling to prevent wear or leakage of the sealing material. Never hit, bend, or stretch the joint artificially to prevent damage to the joint.
