Abstract
To reveal the stress distribution characteristics of throttling flowmeter used in power station boiler under different working conditions, two methods are used to calculate and analyze this kind of flowmeter. The welding seam of throttling flowmeter was calculated by finite element method based on Ansys software, and the stress distribution characteristics under different working conditions were obtained. The results show that there is a large peak stress between the root of the welding seam and the circumferential short joint of the throttle. Based on ASME “Load and Resistance Factor Design" limit analysis method, the results show that throttle flowmeter is easy to crack and fatigue failure when pressure load and temperature load change. The analysis results of the two methods are consistent with the problems in practical application.
