Quick-Connect External Thread Joint Bolts For Pneumatic Pipelines

Product introduction

Quick-plug external thread joint bolts for pneumatic pipelines are the core components for fast and reliable connection in pneumatic systems. One end is an external thread, which can be firmly screwed into the interface of the cylinder or valve body; the other end is an advanced quick-plug structure. Just insert the air pipe and it will automatically lock, sealing and preventing leakage. This design eliminates traditional pipe hoops or cumbersome tools, greatly simplifies the installation and maintenance process, and significantly improves work efficiency. The interior is usually equipped with an O-ring seal to ensure airtightness under high pressure. It is widely used in pneumatic circuits such as automation equipment and production lines that require frequent piping and changes. It is an ideal connection solution to achieve efficient and flexible production.

 

Product Features

1. Quick installation, one-button operation: Using advanced quick-plug design, no tools are needed. Just insert the air pipe directly into the connector and it will automatically lock and fix, achieving one-button connection. When disassembling, you only need to press the locking ring to easily pull out the air pipe, which greatly simplifies the installation and maintenance process and saves time and labor costs.

 

2. Reliable sealing, anti-leakage and anti-off: Equipped with high-quality O-rings (usually nitrile rubber, etc.) inside, which can form a tight sealing ring immediately after the trachea is inserted, effectively preventing leakage of compressed air in high-pressure environments. Its built-in pawl structure can firmly grasp the air pipe to prevent accidental falling off due to vibration or pulling, ensuring long-term stable operation of the system.

 

3. Sturdy and durable, with strong compatibility: The main body of the joint is often made of brass, stainless steel or high-strength engineering plastics, which is corrosion-resistant, vibration-resistant and has a long service life. One end has a standard external thread (such as M5, R1/8, etc.), which can be directly screwed into the equipment air port; the other end is compatible with a variety of specifications of nylon or polyurethane hoses. It has wide adaptability and is an ideal choice for modular design of pneumatic circuits.

 

4. Smooth flow and extremely low pressure drop: The internal flow channel is optimized and smooth, which can minimize air flow resistance and pressure loss, ensure efficient transmission of compressed air, and maintain the best working performance of pneumatic components (such as cylinders and vacuum generators).

 

Product application

1. Automation equipment and production lines: widely used in pneumatic circuit connections on various types of automated machinery, robot arms and assembly production lines. Its quick plug-in feature greatly facilitates the initial installation, position adjustment and daily maintenance of pneumatic actuators (such as cylinders and vacuum suction cups), effectively shortening equipment downtime and improving production efficiency.

 

2. Working conditions with frequent changes and maintenance: In situations where tools need to be frequently changed and pipeline layouts adjusted, such as equipment debugging, maintenance or process changes, quick-connect connectors can quickly disconnect and reconnect air pipes without tools, providing unparalleled flexibility and very suitable for flexible manufacturing systems and laboratory testing environments.

 

3. Compact equipment with limited space: Due to its compact structure and high integration, it is very suitable for use inside control cabinets or equipment with small space and dense wiring. The external thread end can be directly screwed into the interface of the solenoid valve, pressure regulating valve or cylinder, saving space and simplifying the overall structural design.

 

4. Vibration-sensitive application scenarios: On equipment with continuous vibration or pulse operation (such as stamping machines, vibrating feeders), the locking mechanism inside the joint can effectively prevent the air pipe from loosening due to vibration, and its reliable sealing performance can also avoid the resulting leakage, ensuring the stability of the system under harsh working conditions.

 

5. Modular and standardized pneumatic system: It is the core connector of the modern modular pneumatic concept. By pre-installing this kind of joint, the plug-and-play of pneumatic components (such as sensors, small cylinders) can be realized, which facilitates rapid assembly and replacement, and promotes the standardized design and manufacturing of equipment.

 

FAQ

Q: What should I pay attention to when installing the external thread end of the joint?

A: Wrap raw material tape: If you need to enhance the seal, you can wrap 1.5-2 turns of polytetrafluoroethylene raw material tape clockwise on the thread, being careful not to block the air port. Moderate tightening: Use a suitable wrench to screw the connector into the port. The tightening torque should not be too large, otherwise it may cause the threads to slip or the connector shell to crack. Align the threads: Avoid forcing screwing in at an angle to avoid damaging the threads.

 

Q: Are there any requirements for the use environment of quick-plug connectors?

A: Yes. Try to avoid using it in the following environments: high temperature and strong ultraviolet radiation: it will cause aging of plastic parts and failure of sealing rings. Places where chemical solvents splash: Certain chemicals can corrode joint materials and sealing rings. Environment with excessive dust and chips: Impurities may invade the locking mechanism, causing jamming or loose sealing. Under such harsh working conditions, it is recommended to use metal-protected joints.
