In water supply system, when pimp suddenly starts or stops and valve sudden opens and closes, all three will result in sudden change of flow velocity and pressure in pipeline. The high pressure shock out harsh noise, or even mare serious, cracking of pipeline. And then pipeline will lose effect, this is just water hammer. The main cause of this is the incompressibility and motion inertia of fluid and the elasticity shrinkage of pipeline materials.
SS water hammer valve is to only allow the medium to flow in one direction and prevent the direction from flowing. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat to cut off the flow.
The valve flap of the silent check valve is disc-shaped and rotates around the shaft of the valve seat passage. The flow passage is streamlined and the flow resistance is smaller than that of the butterfly check valve. It is suitable for low flow rate and flow. Frequently changing large diameter applications, but not suitable for pulsating flow, the sealing performance is not as good as lifting. The butterfly check valve is divided into three types: single-valve, double-valve and multi-half. These three forms are mainly divided according to the valve diameter. The purpose is to prevent the hydraulic shock from being weakened when the medium stops flowing or reverses.
