Abstract
PURPOSE: To discharge the fluid enclosed in the space between the outside of a valve ball and the inside of a valve chamber effectively during the operation of a ball valve by providing grooves on the outer periphery of the valve ball.
CONSTITUTION: Grooves 12 are provided on the outer periphery of a valve ball 6 to connect a space shaped between the outside of the valve ball 6 and the inside of a valve chamber 5 when the valve ball 6 is at a position to open a valve to an outlet port 4. When the valve ball 6 is at a position to close the valve, it is held between valve seats 7 and 8 in a sealed-up state, and grooves 12 are not connected to inlet and outlet ports 3 and 4. When at the position to open the valve, grooves 12 are brought to cross the valve seat 8, and connect the space between the valve chamber 5 and the valve ball 6 to the outlet port 4. Consequently, fluid is permitted to pass through a passage 9 of the valve ball 6, and also, the fluid accumulated in the space between the valve seat 5 and the valve ball 6 is discharged to the outlet port 4.
