NEUTRAL SURFACES FOR BUTTERFLY VALVE BIPLAN DISK
Due to the eccentricities of the biplane disc of the butterfly valve, the
analysis of the directional stresses can be done by using the numerical
methods. The paper presents the neutral surfaces of butterfly valve biplane disc
obtained by numerical methods. The neutral surfaces are defined as surfaces
with directional stress of zero value or, those surfaces which delimit the passing
of the directional stresses from negative values to positive values.
