<p>PURPOSE:To eliminate the reduction in the pressure of a sealed gas, improve hygiene, and enable long period of safe use by disposing a sealed container nearly coaxially in an airtight rigid tank which container is made of a corrugated tube of thin sheet metal with its both ends capped. CONSTITUTION:The inner space of a sealed container 3 is filled with a specified pressure of gas. Liquid of a fluid supply system or the like is supplied to and discharged from a tank 1 through openings 21 and 22. When the liquid supply system becomes abnormal and a sudden water hammer pressure is produced, non-compressive fluid is supplied to the tank 1. Then the impact wave is absorbed directly with a sealed container 3. The sealed container 3 while contracting its outer corrugated tube 5 receives the pressure fluid. When the fluid pressure of the fluid supply system lowers, the sealed container 3 expands and thus prevents the water hammer of the fluid supply system. The restoration force of the sealed container 3 is obtained in proportion to the deflection of the corrugated tube itself as well as from the compressed gas in the sealed container.</p> |
