WATER LEAKAGE COUNTERMEASURE DEVICE
Document Type and Number:
Japanese Patent JP2020176681
Kind Code:
A
Abstract:
To reduce workload of a worker for water leakage countermeasures.SOLUTION: A water leakage countermeasure device 200 is configured such that in a state where an annular water stop tool 206 composed of a plurality of water stop parts that form an opening having an inner diameter dimension equivalent to an outer diameter dimension of a piston shaft 201 when combined, is overlapped with an additional packing 205 arranged annularly along the outer peripheral surface of the piston shaft 201, a position of the water stop tool 206 with respect to an isolation member 202 is fixed by a water stop tool fixing member 207. Consequently, it is possible to prevent water leakage in a bottom drain valve chamber without replacing an existing UF packing 204, and to reduce workload of a worker for water leakage countermeasures.SELECTED DRAWING: Figure 3
