摘要
Abstract
Based on API 6D pipeline valve needs enough structural strength,stiffness and effective sealing.The stiffness and effective sealing performance of DN2800 buried large-diameter butterfly body was analyzed by using the finit element method in this paper;established a flexural model of butterfly,the maximum bending load of DN2800 butterfly and series products were studied.The results showed:(1)the sealing failure of DN2800 butterfly prior to the stiffness failure under long-term additional load,maximum bending load equal to the effective critical bending load;(2)it shows quadratic function relationship among thicknesst,nominal diameterd,flexural stiffnessK,effective critical bending stiffnessM1,effective critical sealing bending load M2 in DN>1000 mm large-diameter butterfly.Research methods and results provide an effective evidence to maximum bending load of the buried large-diameter butterfly study.关键词
