Abstract

A ball valve which is, principally, installed a ball having through holes and closed components contacted separately with two opening sides of ball in between inlet path and outlet path. Use the valve rod to connect operating part and the ball, and form the opening at flowing-out side of through holes inside the sector-shaped ball valve. Its has the following features. When the valve is closed, set keen-part of sector-shaped opening within the 1st closed component area that is composed by closed component at flowing-out side nearing outlet path. Simultaneously, when it is open, set the keen part of sector-shaped opening to across the outlet path and intrude into the 2nd closed area that is composed by flow-out side component. The opening at flow-in side of through hole has main and auxiliary openings. The auxiliary opening will guide inlet path to through hole during the keen part of sector-shaped is through 1st closed area to begin opening the valve. And the main opening will guide inlet path to through-hole after open the valve.
