swing check valve function
The main function of the swing check valve is to prevent the backflow of the medium, the specific functions include:
Prevent media backflow: through automatic opening and closing, to ensure that the medium can only flow in one direction, thus preventing accidents.
Prevent the pump and drive motor reversal: when the pump stops running, the check valve can prevent the pump and motor reversal due to media backflow.
Eliminate water hammer phenomenon: Through its structural design, it helps to reduce the water hammer effect and protect the piping system.
In addition, the swing check valve is suitable for large-diameter occasions and should not be used for pulsating flow, and its sealing performance is not as good as the lift check valve.
