Scenario:
A water treatment plant uses a Swing-Flex check valve to protect its main pump from water hammer and reverse flow. The valve is installed on the discharge line of the pump.
Task:
1. **Protection from water hammer and reverse flow:** * **Water hammer:** When the pump stops suddenly, the water in the discharge line can continue to move forward due to inertia. This creates a pressure wave that travels back towards the pump, potentially damaging it. The Swing-Flex check valve closes quickly when the flow reverses, preventing this pressure wave from reaching the pump. * **Reverse flow:** If pressure in the distribution system drops below the pressure in the discharge line, water can flow back into the pump. This can cause damage to the pump's impellers and seals. The Swing-Flex check valve prevents this by blocking the flow in the reverse direction. 2. **Potential problems due to malfunction:** * **Valve failure to close properly:** This would allow water hammer to reach the pump, potentially causing damage. * **Valve failure to open properly:** This would prevent water from reaching the distribution system, interrupting service and possibly causing downstream pressure issues.
