Leakproof Design |
Yes, with double shut-off valves to prevent leakage during disconnection |
● High-strength metal: Stainless steel, brass, steel and other high-strength metals are usually used as the main materials. These metals have excellent mechanical properties and fatigue resistance, ensuring the stability and safety of the joint.
● Corrosion resistance: Some double-enclosed quick connectors use special plastics or specially treated metal materials to improve their corrosion resistance, so that they can be used for a long time in corrosive fluids without being affected.
● Sealing materials: The seals inside the joints are usually made of oil-resistant and wear-resistant synthetic rubber or polytetrafluoroethylene and other materials, which have excellent sealing properties and chemical corrosion resistance.
● Lightweight design: On the premise of meeting the strength and sealing performance, some double-enclosed quick connectors use lightweight materials such as aluminum alloy to reduce the overall weight and facilitate carrying and installation.
● Surface treatment technology: In order to improve the durability and aesthetics of the joints, some joint surfaces will be treated with galvanizing, chrome plating, plastic spraying, etc. to enhance their corrosion resistance and visual effects.
Prevent leakage |
When connecting and disconnecting, the double stop valve design ensures that the flow path of liquid or gas at both ends is automatically closed to prevent leakage. |
Easy and fast connection and disconnection |
The quick connection and disconnection function does not require tools to operate, improves work efficiency, and is suitable for application scenarios where connections are frequently changed. |
Improve safety |
The double stop design can prevent operators from being exposed to dangerous fluids or gases, ensuring the safety of operation. |
Prevent cross contamination |
When the connection is disconnected, the double valve design prevents the media in the fluid system from mixing with each other to avoid cross contamination. |
Adapt to a variety of applications |
It is widely used in hydraulics, pneumatics, automobiles, agricultural machinery and other fields, and is suitable for the connection needs of different media and working environments. |
