Abstract：Link butterfly valve has been applied in many occasions. Through the analysis of the motion trajectory of the link butterfly valve， the relationship between the parameters of the link butterfly valve and the motion trajectory of the valve plate are obtained， so as to better understand the motion characteristics of the valve， analyze the flow channel， and then adjust the parameters. Through the trial calculation of the obtained relationship， the most ideal motion characteristics are obtained， and the design is optimized to meet the requirements of various applications.
