FLUID PIPE OPEN HOLE CUTOFF WORK METHOD AND FLUID PIPE CUTOFF DEVICE
PROBLEM TO BE SOLVED: To expand a range of application while making compact formation of stopper means and promoting simplification of a structure of the stopper means.SOLUTION: This invention relates to a fluid pipe cutoff work method for executing a cutoff work step in which an operation shaft 11 of a fluid pipe cutoff device A is installed at a fluid apparatus C arranged at a fluid pipe 1 while being passed therethrough, a stopper member 12 for the operation shaft 11 is inserted from a communication flowing-in part 8 in the fluid apparatus C into the fluid pipe 1 while passing through an open hole 2 under an insertion/extraction attitude, the stopper member 12 is changed over to an engaging attitude of being engaged with an opening peripheral edge of the open hole 2, and either the open hole 2 or the communication flowing-in part 8 is cut off by cutoff means D of the operation shaft 11; and a cutoff releasing work step in which the cutoff by the cutoff means D is released and the stopper member 12 is passed through the open hole 2 and drawn out to the communication flowing-in part 8 under a state in which the stopper member is changed over to the insertion/extraction attitude. The changing-over work to at least one of the engaging attitude or the insertion/extraction attitude of the stopper member is executed through an abutment with the fluid pipe 1.SELECTED DRAWING: Figure 1
【課題】抜止め手段のコンパクト化と構造の簡素化を促進しながら適用対象範囲の拡大を図る。【解決手段】流体管１に付設された流体機材Ｃに、流体管用遮断装置Ａの操作軸１１を貫通状態で装着し、この操作軸１１の抜止め部材１２を流体機材Ｃ内の連通流入部８から貫通孔２を挿抜姿勢で通過して流体管１内に挿入し、抜止め部材１２を貫通孔２の開口周縁に係合する係合姿勢に切替作動し、操作軸１１の遮断手段Ｄにより貫通孔２又は連通流入部８を遮断する遮断作業工程と、遮断手段Ｄを遮断解除し、抜止め部材１２を挿抜姿勢に切替作動させた状態で貫通孔２を通過して連通流入部８に引き出す遮断解除作業工程とを実行する流体管の遮断作業方法であって、抜止め部材の係合姿勢又は挿抜姿勢への切替作動のうち、少なくとも一方への切替作動を流体管１との当接によって実行する。【選択図】図１
