VALVE ELEMENT REMOVAL DEVICE AND VALVE ELEMENT REMOVAL METHOD
To provide a valve element removal device which is applicable to various valve devices, eliminates the need to enclose the entire valve device, and is capable of tightly enclosing a duct part body and valve body part with a working case only through work closer to the valve body part than a fluid duct, and a valve element removal method.SOLUTION: A valve element removal device comprises: a work case 30 which encloses only the side of a valve body part 11 in a valve device 2 in a tight state; an operation valve 26 which partitions an internal space of the work case 30; valve movement means 91 which is provided in the work case 30 and makes the valve body part 11 movable inside of the work case 30; and coupling members 23 and 25 which couple a first flange 6 provided in a duct part body 3 and a second flange 13 provided in the valve body part 11. The work case 30 is constituted of a first split body 31 and a second split body 61 which encloses the valve body part 11. The first split body 31 is divided into two parts at least in a circumferential direction of the first flange 6, and a jack supporting weights of the work case 30 and water in the work case 30 and achieving the level is interposed between the work case 30 and a dug ground surface.SELECTED DRAWING: Figure 9
【課題】種々の弁装置に適用可能であるとともに、弁装置全体を囲う必要がなく、流体管路よりも弁本体部側での作業のみで管路部本体及び弁本体部を作業用ケースで密封状に囲うことのできる弁体撤去装置及び弁体撤去方法を提供すること。【解決手段】弁体撤去装置は、弁装置２のうち弁本体部１１側のみを密封状態に囲う作業用ケース３０と、作業用ケース３０の内部空間を仕切る作業弁２６と、作業用ケース３０に設けられ弁本体部１１を作業用ケース３０内で移動を可能とする弁移動手段９１と、管路部本体３に設けられた第１フランジ６及び弁本体部１１に設けられた第２フランジ１３を締結する締結部材２３，２５と、を備え、作業用ケース３０は、第１分割体３１と、弁本体部１１を囲う第２分割体６１から構成され、第１分割体３１は、第１フランジ６の周方向に少なくとも２分割されており、作業用ケース３０及び作業用ケース３０内の水の重量を支持するとともに水平を出すジャッキが、作業用ケース３０と掘削地面の間に介設されている。【選択図】図９
