Problems solved by technology
Due to the rapid switching action of fast-acting valves, conventional detection methods (such as stopwatch timing, etc.) cannot meet the requirements of accurate testing, resulting in the system operation and maintenance personnel unable to accurately understand the valve response time, and thus unable to arrange necessary maintenance and adjustment work in advance. Hidden dangers left by the safe operation of the system

The invention belongs to the technical field of nuclear power maintenance, and particularly relates to a method and a device for testing response time of a valve. The method comprises the steps of in a first preset time period, acquiring vibration signal values of a to-be-detected valve moving part at all detection moments in the first preset time period; taking the vibration signal value greater than the vibration signal threshold value in the first preset time period as an effective vibration signal value; and determining the response time of the to-be-detected valve according to the moments corresponding to the multiple effective vibration signal values. Through the non-intrusive measurement method, the valve switch response time is tested during the shutdown or operation period of the unit, the switch response performance state of the valve can be accurately mastered through the change of the vibration signal value of the valve moving part, the potential safety hazard of the system is eliminated, and the safe and economic operation indexes of industrial enterprises including nuclear power plants are improved. In addition, interference data can be effectively filtered, a data processing amount is reduced, and therefore the data processing efficiency and accuracy are improved.
Description
technical field [0001] The invention belongs to the technical field of nuclear power maintenance, and in particular relates to a method and a device for testing the response time of a valve. Background technique [0002] Valves are executive elements in process control systems in the industrial field. They are widely used in the system loops of nuclear power plants and conventional power plants. Their performance is directly related to the economic operation indicators of the power plant. The failure of some safety system valves will Lead to serious safety accidents and major economic losses. [0003] There are many types of valves and their uses are extremely wide. According to their uses, they usually include regulating valves, globe valves, and one-way valves, etc.; according to their types, they generally fall into two categories: automatic valves and actuated valves. Fast-acting valves do not specifically refer to a certain type or a certain purpose of valves. It is a ...
