Abstract:

A performance evaluation technology was studied for the performance evaluation of high temperature forging steel gate valve based on the American Society of Mechanical Engineers (ASME) code and finite element analysis method.In order to ensure the safe and reliable operation of the gate valve under high temperature conditions, a method of evaluating the temperature field and stress field for the high temperature forging steel gate valve by finite element software Ansys was introduced. The temperature field and total stress field of the valve was calculated, so as to perform the stress evaluation and estimate the structural performance.The results show that the height of the bonnet cylinder is sufficient, the design area of the heat sink is reasonable, and the pressure-bearing boundary components can meet the strength requirements, which would have good prospects in engineering apparitions.

Key words: gate valve, temperature field, thermo-solid coupling evaluation, finite element analysis method, stress field
