Analysis of valve sealing mechanisms and leakage prevention techniques

In a pipeline, valves are mechanical devices that control the flow of fluids. The key to their effectiveness is their capacity to provide a tight seal when closed, limiting the unintentional escape of fluids. Valves use a variety of sealing methods, each of which is tailored to a particular operating need. Ball valves: To control flow, these valves use a spherical ball with a hole in it in the middle. To permit or prevent fluid flow, the ball is spun while it is within a chamber. The ball forms a tight seal against the valve seat when it is closed.
