Swing type check valve is a check valve that the disc rotates around the rocker shaft in the body cavity. Swing check valve consist of body, cover, disc and rocker. The inner passage of the valve is streamlined, and the flow resistance is smaller than that of the straight type lifting check valve, which is suitable for large-diameter pipelines. At the same time, in order to improve the sealing performance can be used with auxiliary spring or heavy hammer structure auxiliary seal.Swing type check valve is relatively resistant to flow when opened. In addition, because the disc is suspended in a fluid, turbulent flow can occur. When the direction of flow suddenly changes, the disc will slam against the seat, causing great wear on the seat and water hammer along the pipe. To overcome this problem, the disc of the swing type check valve can be damped and the metal seat reduced seat wear.
