Abstract
The invention relates to a ball valve which controls fluid motion in a fluid system. The ball valve comprises a valve body mechanism and a ball. The valve body mechanism comprises a channel, an inlet seal ball seat and a ball pushing device. The ball valve is characterized in that the valve body mechanism is provided with a push rod cavity ball seal seat which is provided with a push rod cavity; the ball valve comprises a ball core cavity formed by the push rod cavity ball seal seat, the inlet seal ball seat, the ball pushing device and the channel; and the inlet seal ball seat is provided with a channel for fluids to enter the ball core cavity, and the ball is assembled in the ball core cavity. The ball is tightly pressed on the inlet seal ball seat through the ball pushing device to achieve closing of the channel. After pressure on the ball is released through the ball pushing device, the ball is pressed on the push rod cavity ball seal seat under the pressure effect of working media, the channel on the inlet seal ball seat is opened, and thus the working media are prevented from being leaked from the ball core cavity to the push rod cavity.
