Abstract
A control method of a filled water volume in a fluid space requiring a water filling test is disclosed. The method includes disposing a pipe in the fluid space and enclosing the pipe with an enclosure, detecting pressure of a water filled portion in the fluid space or outside of the enclosure, and controlling the volumes of filling fluid and water to a water filling portion in the fluid space inside and outside the enclosure based on the detected pressure such that the pressure in the enclosure becomes higher than the pressure at the water filling part in the fluid space outside the enclosure.
Claims8
A control method for a filled water volume in a storage fluid space having at least one piping system, comprising:
- providing an enclosure;
- enclosing the at least one piping system inside the storage fluid space with said enclosure;
- detecting a pressure of a first body of water inside the enclosure and a pressure of a second body water outside the enclosure within the storage fluid space;
- controlling the volume of the first body of water inside the enclosure and the volume of the second body of water outside the enclosure based on the detected pressures so that the pressure of the first body of water charged inside the enclosure is higher than the pressure of the second body water charged outside the enclosure.
A control device for a filled water volume in a storage fluid space having at least one piping system, comprising:
- an enclosure that encloses each piping system inside the fluid storage space;
- a pressure detecting means that detects a pressure of a first body of water inside of the enclosure and a pressure of a second body of water outside the enclosure within the storage fluid space;
- a control means that controls the volume of the first body of water inside the enclosure and the volume of the second body of water outside the enclosure based on the detected pressures so that the pressure of the first body of water charged inside of the enclosure is higher than the pressure of the second body of water charged outside of the enclosure.
