The invention belongs to the technical field of analysis and detection, and relates to a water vapor sample temperature and flow control system and control method. The system includes a primary cooler, a pressure reducing valve, a secondary cooler, a pressure gauge, a second thermometer and an adjustable flowmeter; the The primary cooler, the pressure reducing valve, the secondary cooler and the adjustable flowmeter are communicated in sequence; the pressure gauge and the second thermometer are respectively communicated with the pipeline between the secondary cooler and the adjustable flowmeter. The invention can accurately control the temperature, pressure and flow of the water vapor sample through two-stage temperature and flow control, meet the sampling requirements, analyze and test the result data is stable and accurate, provide accurate data support for water vapor supervision, and ensure the safety of large-scale power plants. normal operation. |
