How to prevent the water hammer effect of a silencing check valve: At the moment when the silencing check valve stops pumping, the check valve core needs to return to the closed position in advance due to the balance of force on both ends under the action of springs or other auxiliary devices, which can greatly reduce the amount of initial water return and the height of water head drop. The water hammer force is calculated by adding gravity acceleration and other factors, and the reduced return water amount is equivalent to reducing gravity, The short fall height reduces the time for inertia formation and also reduces the speed, which can prevent the formation of water hammer or reduce the destructive force of water hammer.

How to Prevent Water Hammer Effect by Silencing Check Valves

Quick closing silencing check valve, also known as energy-saving silencing check valve, refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself to prevent medium backflow. It is also known as a check valve, one-way valve, silencing check valve backflow valve, and backpressure valve. A check valve is an automatic valve that primarily functions to prevent media backflow, prevent pump and drive motor reversal, and discharge container media. Check valves can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
