More Information
Summary:Provided in the present invention are a valve disk for a valve installed on a duct for blocking and controlling the flow of fluid, adjusting the pressure of fluid, and preventing a countercurrent, and a butterfly valve using the same. According to the valve disk (10) and butterfly valve (10′) using the same of the present invention, when an action force is generated by a fluid controlled by the valve disk (10) having a dual structure of an internal disk (12) and an external disk (14), the action of the internal disk (12) can minimize the deformation applied to a rotation shaft (18), thus effectively offsetting the deformation applied to the rotation shaft of the valve disk installed on a duct for blocking and controlling the flow of fluid, adjusting the pressure of fluid, and preventing a countercurrent.
