Maintenance of Power Station Valves

In order to ensure the normal and effective operation of the power station valve, relevant staff are required to study and analyze its possible problems, and find corresponding maintenance countermeasures to ensure the reliability of the power station valve. The specific maintenance strategy is as follows：
 
Regular maintenance and inspection
Regular inspection and maintenance of power station valves is an important means to ensure the reliable and safe operation of power station valves. Therefore, the inspection and maintenance of power station valves should be done well. At the same time, it is also necessary to summarize the methods of safe operation and simplified maintenance of valves on time. By effectively ensuring the above two standards, the effective operation of valves is ensured, thereby promoting the development of power stations and the sustainable and stable development of the power industry.
 
Taking different measures for different problems
In the actual application process of power station valves, their main problems are vibration, control, strength and other aspects. Through the analysis of the above problems, it is found that the problems of power station valves have the characteristics of complexity and diversity, but the reasons for these problems are similar. In order to solve these problems effectively, it is necessary for the relevant staff to comprehensively and systematically analyze the influencing factors of the power station valve, fully understand and grasp the essence of the problems related to valves so as to find the cause of the problem and propose relevant measures to ensure the effective operation of the valve. Among these problems, factors such as strength, dynamic, static force and stability are the main factors, and the research and control of these factors should be strengthened.
 
Doing a good job in inspection and monitoring of valves
In the process of selecting the valve, the quality inspection of the valve should be done well, that is, the various quality characteristics of the valve should be observed, measured, and tested so as to ensure that the quality of the valve meets the needs of use and give full play to the important performance of the valve. In addition, in order to effectively solve the problem of the valve, the valve's control system should be improved, and the system failure should be diagnosed in real time so as to ensure the production quality of the valve and then promote the development of the power industry. In the context of the continuous development of information technology, online monitoring technology has been developed and utilized, which can monitor the status of equipment in real time and dynamically. Therefore, this technology can be applied to monitoring valves to effectively obtain operating data of valves and make effective judgments and problems solved. At the same time, the application of this technology also improves the operability of the valve, reduces the maintenance frequency of the valve to a certain extent and the maintenance cost and increases economic benefit.
 
Process analyses of power station valves
The purpose of closing the power station valve can be achieved by moving the valve disc, and there are many ways of moving it. The appropriate moving method should be selected according to the actual situation of the power station valve. The efficiency and reliability of the cutting off can be guaranteed to a certain extent due to the short opening and closing stroke of the valve stem. For globe valves, the valve disc is usually made of cast steel or forged steel. When the valve disc is opened, the valve seat and the valve disc sealing surface will be effectively separated, thereby reducing the mechanical wear degree of the sealing surface and making it have good sealing performance. However, the sealing surface also has certain shortcomings, that is, some particles will adhere to the sealing surface. In order to effectively avoid this problem, the valve disc should be made into steel balls or ceramic balls as much as possible. In addition, the maintenance and replacement of the valve disc and valve seat in the general globe valve are relatively easy, and the overall disassembly and assembly of the valve are not required. The connection between the valve and the pipeline can be realized by an integrated welding method.
 
Conclusion
To sum up, the valve of the power station is an important device for its effective operation. When it fails, the cause of the valve problem should be found and corresponding measures should be formulated to solve it. At the same time, strengthen regular maintenance and real-time monitoring to reduce the occurrence of failure rates and increase the economic benefits of the power station.
