Abstract

The invention discloses a valve sound wave monitoring system and method. The system comprises valves installed in a fluid pipeline, sound wave sensors installed at the corresponding valves and used for collecting sound wave signals at the corresponding valves and transmitting the sound wave signals to a signal transmission device, the signal transmission device used for receiving sound wave signals collected by the sound wave sensors and sending the sound wave signals to a sound wave data analysis platform, and the sound wave data analysis platform used for receiving and analyzing the sound wave signals uploaded by the signal transmission device. The analysis specifically comprises one or more of analyzing the working state of the valves, analyzing whether the valves leak or leak inwards,correcting the opening degree of the valves, monitoring the flow of the valves and analyzing whether the valves vibrate or not. According to the valve sound wave monitoring system and method, real-time continuous online monitoring of a pipe network and the valves is achieved through the relatively cheap sound wave sensors, so that the cost is low, and the precision and the accuracy are high.

Description

technical field [0001] The invention relates to the technical field of valve monitoring, in particular to a valve acoustic wave monitoring system and method. Background technique [0002] As a general mechanical component, valves have the functions of cut-off, diversion, and adjustment; their requirements involve petrochemical, electric power, transportation, food and other basic fields; valves can be used to control air, water, steam, various corrosive media, mud, oil products , liquid metal and radioactive medium and other types of fluid flow. However, due to various reasons such as corrosion and aging, the valve often fails and causes leakage. If it cannot be dealt with in time, it will easily lead to safety accidents; especially, most of the urban fluid pipelines are buried under the ground, so it is difficult to monitor, and it is often difficult to find the fault of the valve. Fault. [0003] Therefore, timely and effective monitoring of valve status, timely detectio...
