<p>PROBLEM TO BE SOLVED: To provide a water hammer phenomenon preventing structure capable of being installed in a narrow space in a simple structure and at a low cost. SOLUTION: This water hammer phenomenon preventing structure 10 comprises a pressure regulating pipeline 11 for communicating a predetermined negative pressure occurring place of a water duct 3 with a predetermined water supply place having a pressure allowing water supply for this negative pressure occurring place, and a check valve 12 that is disposed in the pressure regulating pipeline 11 and prevents backflow of the water from the negative pressure occurring place to the water supply place. In this water hammer phenomenon preventing structure 10, the water is supplied through the pressure regulating pipeline 11 at a negative pressure occurring time, and occurrence of the water hammer phenomenon can be prevented in a simple and inexpensive structure.</p> |
