The spherical surface is introduced to form the front of disc and cone contact for the seating couple; these structures will extremely the shock force of medium and decrease the resistance coefficient of flow.  Thin shell structures is employed when design the diversion component to ensure the laminar flow and greatly drop the weight.  The reasonable open height and cavity space enable the obtaining of maximum area of flow section.  It can avoid occurring of the air chamber; the valve parameter Cv is improved.
