3. Sikkerhedsoplysninger
Always adhere to the following safety guidelines to prevent injury or damage to equipment:
- Ensure the system pressure does not exceed the maximum rated pressure for both coupled and uncoupled states.
- Verify material compatibility with the system fluid to prevent corrosion or degradation.
- Always depressurize the system before attempting to connect or disconnect the quick connect, unless the valved design specifically permits otherwise under controlled conditions.
- Wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves, during installation and maintenance.
- Do not use damaged or worn components. Inspect the quick connect regularly for signs of wear, cracks, or corrosion.
- Avoid overtightening threaded connections, which can cause damage. Refer to industry standard torque specifications for NPT connections.
4. Opsætning og installation
Proper installation is crucial for the performance and longevity of the quick connect.
4.1. Forberedelse
- Inspect all components for any damage or debris. Ensure the threads are clean and free of burrs.
- Apply a suitable thread sealant (e.g., PTFE tape or liquid sealant) to the male NPT threads of the system piping before connecting to the 1/4" Female NPT end of the quick connect.
4.2. Connecting the Quick Connect to System Piping
- Thread the quick connect body onto the male NPT fitting of your system piping.
- Hand-tighten, then use a wrench to tighten to the recommended torque for 1/4" NPT connections, typically 1/2 to 1 turn past hand-tight, or as specified by your thread sealant manufacturer. Do not overtighten.
4.3. Connecting the Stem to the Body
- Ensure both the stem and body are clean.
- Align the stem with the quick connect body.
- Push the stem firmly into the body until a positive click is heard or felt, indicating that the locking mechanism has engaged.
- Gently pull on the stem to confirm it is securely locked in place.
5. Betjeningsvejledning
The Swagelok QTM Series Quick Connect is designed for ease of use.
5.1. Tilslutning
To connect, simply push the stem into the body until it locks. The DESO-Valved design minimizes fluid loss during this process.
5.2. Frakobling
To disconnect, pull back the knurled sleeve on the quick connect body. This will release the locking mechanism, allowing the stem to be pulled free. The DESO-Valved stem will close upon disconnection, limiting fluid release.
6. Vedligeholdelse
Regular maintenance ensures optimal performance and extends the life of your quick connect.
- Rensning: Keep the quick connect clean and free of dirt, dust, and debris. Use a clean cloth and a mild solvent if necessary.
- Inspektion: Periodically inspect the quick connect for signs of wear, especially on the O-rings and sealing surfaces. Look for scratches, nicks, or deformation.
- Udskiftning: If any part of the quick connect appears damaged or worn, replace the entire unit or the specific worn component if a repair kit is available from Swagelok. Do not attempt to repair damaged parts that are not designed for field repair.
- Opbevaring: When not in use, store the quick connect in a clean, dry environment to prevent contamination and corrosion.
