The accumulator air inlet valve QXF-5 has become an indispensable key component in the EH oil system of the steam turbine of a power plant due to its excellent performance, simple operation and reliable safety. It can not only accurately control the charging process of the accumulator to ensure the safety and efficient operation of the accumulator, but also effectively extend the service life of the accumulator and reduce the maintenance cost of the system. In practical applications, the correct installation, use and maintenance of the QXF-5 intake valve is of great significance to ensure the stable operation of the EH oil system of the steam turbine of a power plant.
Technical features and advantages
1. Excellent performance
The accumulator air inlet valve QXF-5 has the characteristics of small size, high pressure resistance and good self-sealing performance. Its nominal diameter is 5mm and the charging pressure range is 4~40MPa. It can adapt to various accumulator models and meet the inflation requirements under different working conditions. At the same time, the valve has strong compatibility and is suitable for various accumulator models such as NXQ-0.6~100/-H, with good versatility.
2. Easy operation
The intake valve is easy to operate. The valve opening and closing can be easily controlled by rotating the handwheel. It opens by rotating clockwise and closes by counterclockwise, which is convenient for on-site operation and maintenance. In addition, the valve will automatically close after the inflation is completed to form a seal to ensure that the gas does not leak and improve the safety of the system.
3. Safe and reliable
The accumulator air inlet valve QXF-5 is equipped with a pressure regulating device, which can set and adjust the working pressure of the accumulator to ensure that the accumulator operates within the safe pressure range. When the internal pressure of the accumulator exceeds the preset value, the valve can automatically close to prevent the accumulator from being subjected to excessive pressure, effectively protecting the accumulator bladder and other components from damage.
Application scenarios and importance
1. Key role in EH oil system
In the EH oil system of the power plant turbine, the accumulator is responsible for storing energy, absorbing shocks and stabilizing pressure, and the accumulator air inlet valve QXF-5 plays a vital role in it. It can ensure that the accumulator responds quickly when the system pressure fluctuates and maintains the stability of the system pressure, thereby ensuring the normal operation of the turbine.
2. Maintenance and care
In order to ensure the long-term stable operation of the accumulator air inlet valve QXF-5, it is necessary to inspect and maintain it regularly. It mainly includes checking the sealing status and working conditions of the valve to ensure that the valve is leak-free and flexible; avoid external force impact or damage to the inflation valve and its connecting pipes; if the sealing performance is found to be reduced or leaking, it should be repaired or replaced in time to ensure the safe operation of the system.
