Adding pneumatic butterfly valve is a common safety method
The pneumatic butterfly valve itself will be damaged due to the limit of service life and the impact of the environment during use. Therefore, it is necessary to find problems in time to reduce the possibility of injury. The current operation is only used in the nuclear island, not in the main steam system, but the main steam pilot pneumatic butterfly valve has a good use record in foreign operations.
Reasonably evaluate the online detection of pneumatic butterfly valves Reasonably evaluate the online detection of pneumatic butterfly valves Online detection of pneumatic butterfly valves is to solve the problem of continuous extension of the operation cycle of large-scale production equipment, including safety leakage.
The basic theory of modern design is used for research. By creating a morphological matrix, many original understandings of functionality are established, and a set of feasible schemes are obtained. After evaluation, a feasible research scheme was selected. So far, the core of almost all commercial pneumatic butterfly valve detection is like this, that is, the valve core of the pneumatic butterfly valve is opened by external force, and when using the computer data acquisition system, the open state is judged for detection, and on-site verification (set pressure) can be achieved without disassembly.
