  9. The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
