Check valves are mainly used in the water supply system of pumps to prevent the impact of high-pressure water backflow on the impeller of pumps. When the water pump in the water supply system suddenly stops running, the pressure in the pump immediately disappears, and the high-pressure water connected to the pump outlet will flow back to the pump.
