Flange ball valve is a valve that opens and closes by rotating the ball around the center line of the valve body. It is mainly used in pipelines to cut off, distribute and change the flow direction of media. The ball of the flange ball valve can be rotated through the valve stem to achieve the flow or cutoff of the medium.
Working principle
The working principle of the flange ball valve is to realize the flow or cutoff of the medium by rotating the ball. When the ball rotates to align with the inner diameter of the pipe, the medium can flow freely; when the ball rotates 90 degrees and presses tightly against the valve seat sealing ring, the medium is cut off, thereby achieving complete sealing.
Structure and features
The flange ball valve has a compact structure and is simple to operate. It only needs to be rotated 90 degrees to open and close. The inner cavity of the valve body provides a straight flow path with low resistance for the medium, and is suitable for various media such as water and natural gas. Flange ball valves are also resistant to high temperatures and corrosion, making them suitable for harsh working environments.
