使用建议
建议定期检查波纹管组件表面状态，发现异常变形应及时停机检测。安装时需确保管道内无焊渣等硬质颗粒残留，首次投用前应进行全行程动作测试。介质温度超过200℃时建议配套散热支架使用。
【Stainless Steel Welded Bellows Globe Valve Product Introduction】
Product Overview
The medium-welded bellows stainless steel globe valve is an industrial valve featuring advanced sealing technology, specifically engineered for precise fluid control in demanding operating conditions. With its core component integrating welded bellows and stem technology, it effectively isolates media from external environments, making it suitable for pipeline systems handling water, steam, petroleum products, and mildly corrosive substances. Manufactured with premium stainless steel for body and critical components, this valve combines corrosion resistance with stable performance under high-temperature and high-pressure conditions, ideal for long-term service in petrochemical plants, thermal energy systems, and specialized chemical processing applications.
Structural Advantages
- Dual Sealing System: The innovative combination of bellows assembly and packing seals creates redundant protection against leakage. Multi-layer precision-welded bellows undergo rigorous pressure cycle testing to maintain exceptional sealing performance even after prolonged operation.
- Maintenance-Friendly Design: Full-bore flow passage minimizes pressure drop, while specially engineered seat configuration reduces erosive wear. The self-lubricating stem guide system ensures consistent operating torque and extended service intervals.
- Safety Enhancement: Integrated anti-rotation mechanism prevents bellows torsion deformation, with upper stroke limiter protecting against overtravel damage. Monolithic forged bonnet-body construction improves structural integrity and vibration resistance.
Typical Applications
This product is widely implemented in:
• Steam distribution networks for thermal power plants
• Process pipelines in refining installations
• Sanitary fluid control systems for pharmaceutical equipment
• Industrial boiler feedwater circuits
• Marine propulsion system pipelines
Operation Guidance
Regular visual inspection of bellows surface condition is recommended, with immediate shutdown required if abnormal deformation is detected. Ensure complete removal of pipeline debris before installation. Conduct full-stroke operation test prior to initial commissioning. Auxiliary cooling brackets are suggested for applications exceeding 200℃ medium temperature.
