Title:
CONTROL METHOD AND DEVICE OF FILLED WATER VOLUME IN FLUID SPACE
Document Type and Number:
WIPO Patent Application WO/2009/050826
Kind Code:
A1
Abstract:
There are provided a control method and a device of a filled water volume in a fluid
space through which the fluid space can be filled with water while preventing
a pipe in the fluid space from making contact with the filling water by controlling
the filled water volume. The control method of a filled water volume in a fluid
space requiring a water filling test 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 inside or outside the enclosure; and controlling,
based on the detected pressure, the volumes of filling fluid and water to a water
filling portion in the fluid space inside and outside the enclosure, such that
the pressure in the enclosure becomes higher than the pressure at the water filling
part in the fluid space outside the enclosure.
