ーズボールバルブ。 On the upstream side of a ball valve device that opens and closes by rotating a ball having a through hole approximately 90 degrees, when fluid overflows, a disc moves against the force of a spring due to the fluid flow and comes into contact with a disc seat. An overflow prevention valve device is installed to stop the flow of fluid, and when the ball valve device is closed, the ball contacts the disc, releases the disc from the disc seat, and releases the disc by the force of the spring. In a fuse ball valve designed to be reset, a spherical part is provided at the tip of the disc, and when the ball valve device is closed, the ball contacts the disc seat until the ball valve device is almost closed. A fuse ball valve that has a groove in the contact area with the spherical part of the ball to prevent contact with the ball.
