Abstract

The invention provides a steam turbine high-pressure regulating valve state monitoring system. The monitoring system comprises a laser sensor module, a communication module and a computer system; the laser sensor module is installed on a peripheral flange opposite to a valve rod of a target regulating valve; the valve rod is provided with a target detection section; the target detection section is processed into same contours with precise equal angles or equal intervals along the circumference of the periphery; the communication module is connected with the laser sensor module and is used for transmitting test data of the laser sensor module to the computer system in real time; and the computer system is used for analyzing the data of the laser sensor module and controlling the laser sensor module to adjust working parameters. By analyzing reflected light signals of a laser sensor, a manager can be early warned when abnormal conditions such as inclination, rotation angle differences and deformation of the valve rod occur.

Description

technical field [0001] The invention relates to the technical field of steam turbine monitoring. Specifically, it relates to a state monitoring system for a high-pressure regulating valve of a steam turbine. Background technique [0002] The steam turbine is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle through the regulating valve to become an accelerated air flow and then sprays on the blades, so that the rotor equipped with blade rows rotates and works externally. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant; also because of the importance and complexity of steam turbines in the field of energy and power industries, every country has invested a lot of resources. Research on the development of steam turbine manufacturing technology; the technical level of steam turbines can also roughly reflect the level ...
