The Importance of Maintenance for Bellows Stop Valve WJ25F1.6P
The bellows stop valve WJ25F1.6P is a manual valve in the hydrogen cooling system of the generator, and its maintenance importance is reflected in the following aspects:
1. Ensure the sealing and safety of the system
The sealing performance of bellows globe valves directly affects the safety of hydrogen cooling systems. Hydrogen is a flammable and explosive gas, and any small leak can lead to serious safety accidents. Regular maintenance can ensure the sealing of valves, reduce the risk of leakage, and protect the safety of personnel and equipment.
2. Maintain stable system operation
The bellows globe valve WJ25F1.6P is used in hydrogen cooling systems to control the flow of hydrogen gas. Regular maintenance can ensure the flexibility and reliability of the valve, avoid hydrogen supply interruption or pressure abnormality caused by valve failure, and thus ensure the stable operation of the generator.
3. Extend the service life of equipment
Regular maintenance can promptly detect and repair valve wear, corrosion, and other issues, avoiding small problems from escalating into major failures, thereby extending the service life of valves and reducing equipment replacement costs.
4. Comply with industry standards and regulations
According to the standards of the power industry, such as DL/T 1766.1-2017 "Guidelines for Maintenance of Water Hydrogen Hydrogen Cooled Steam Turbine Generators Part 1: General Principles", the maintenance of generators and their ancillary systems should be based on preventive testing and operational data to ensure the reliability and safety of the equipment. As a key component, the maintenance of the bellows globe valve is an important step in compliance with industry standards.
5. Support overall system maintenance
The normal operation of the generator hydrogen cooling system depends on the good condition of each component. The maintenance of the bellows globe valve is part of the overall system maintenance. By ensuring the normal operation of the valve, it can support the efficient operation of other equipment such as hydrogen coolers and hydrogen dryers.
6. Reduce the risk of hydrogen leakage
Maintenance can identify and repair potential leakage points, ensuring the sealing of the hydrogen system. This is crucial for reducing the hydrogen leakage of the generator and meeting the hydrogen leakage standards under rated operating conditions (such as 12Nm ?/24h).
