摘要
A valve for controlling fluid flow comprises a body having an inlet and an outlet, the body having an opening at one end; a controlling stem disposed axially of the body with one end portion extending through the body opening, the stem being pivotable about the body opening between a normal position when the valve is closed and a pivoted position when the valve is open; and a first elastic ring disposed within the body in sealing contact with the stem and disposed between with the inlet and the outlet, thereby to prevent fluid flow from the inlet to the outlet. The stem when in the pivoted position being adapted to deform the first elastic ring to create an opening between the stem and the first elastic ring, thereby to permit fluid to flow from the inlet through the opening to the outlet.
