摘要

PROBLEM TO BE SOLVED: To provide a flow control body installation device and a flow control body installation method for an existing pipe, which can achieve reduction in size of the whole flow control body installation device by suppressing the amount of stroke into a first case from an inside of a second case for the flow control body.;SOLUTION: A seal case includes: a first case 3 that is fixed to the existing pipe 1 and that is provided with an on-off valve 7; and a second case 13 that is composed of a base body 15 connected to the first case 3 and a movable body 16 provided with the flow control body 11 movable with respect to the base body 15 and an advance/retreat driving part 14 capable of making the flow control body 11 advance to/retreat from a predetermined cut location. The first case 3 and the base body 15 are connected together, and the movable body 16 is moved toward the predetermined cut location to move the flow control body 11 to a position adjacent to the predetermined cut location. Subsequently, the flow control body 11 arranged in the position adjacent to the predetermined cut location is advanced toward the predetermined cut location by the advance/retreat driving part 14.;COPYRIGHT: (C)2013,JPO&INPIT
