Response Surface Optimization of Hard Sealing Structure for a Tri-eccentric Butterfly Valve
摘要
Abstract
The sealing performance and service life of metal hard sealed tri-eccentric butterfly valve are determined by the sealing specific pressure in a closed state,and optimizing the structure parameter of the metal hard sealing components is very important.The DN600 tri-eccentric butterfly valve is taken as the research object.Using the finite element analysis method,the distribution law of the sealing specific pressure on the sealing surface is analyzed.The circumferential clearance index of the sealing mating surface is proposed to estimate the sealing performance of the butterfly valve.The Box-Behnken response surface optimization method is used to optimize the structure of the sealing component.The influence of the cutting thickness of the major,minor diameter ends of the composite valve plate seat,the diameter of the composite valve plate seat and their interaction on the maximum sealing specific pressure of the sealing surface is discussed,and a optimal design solution is obtained.The research results show that the maximum sealing specific pressure of the sealing surface is dropped from 202.96 MPa to 128.44 MPa after optimizing the composite valve plate seat parameters,and the sealing performance of the valve is still good.The reliability of the sealing performance of the optimized butterfly valve is verified through a closed pressure sealing test.关键词
