Adding A Pneumatic Butterfly Valve Is A Common Safety Method
Sanitary Butterfly Valve itself will be damaged due to the limitation of service life and the influence of the environment during use. Therefore, it is necessary to find problems in time to reduce the possibility of causing harm. 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 record of use in foreign operations.
Reasonable evaluation of pneumatic butterfly valve online detection Reasonable evaluation of pneumatic butterfly valve online detection Pneumatic butterfly valve online detection is to solve the problem of continuous extension of the operation cycle of large-scale production equipment, including safety leakage.
Using the basic theory of modern design for research, by creating a morphological matrix, many functional original understandings were established, and a set of feasible schemes were 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 with the help of external force, and the opening state is judged when using a computer data acquisition system for detection, and field verification (set pressure) can be achieved without disassembly.
Basic performance of pneumatic butterfly valve and the basic performance of pneumatic butterfly valve and the basic performance of time terminology of pneumatic butterfly valve Basic performance of pneumatic butterfly valve Pneumatic butterfly valve is used in pressure equipment, containers or pipelines as an overpressure protection device.
When the pressure in the equipment, container or pipeline rises above the allowable value, the valve automatically opens and then discharges all of it to prevent the pressure in the equipment, container or pipeline from continuing to rise; when the pressure drops to the specified value, the valve should automatically close in time to protect the safe operation of the equipment, container or pipeline. The pneumatic butterfly valve can be directly driven by the system pressure at the valve inlet. In this case, the mechanical load provided by a spring or a heavy hammer overcomes the moderate pressure acting under the valve disc.
