Title: Inflatable isolation tool with enhanced monitoring unit
Inventor: BERUBE GUY
IPC: G01M3/28
Filed: 2018-04-02
Abstract: The present invention relates to an inflatable isolation tool having an improved monitoring unit. The isolation tool is to be installed in a pipe bore to separate a section of a bore while a pipe section is being replaced. Also, the isolation tool is to provide a sealing barrier extended in a horizontal direction across the pipe bore. The isolation tool includes a pair of inflatable sealing units installed in a middle tool section by a ring-shaped lower assembly preventing the sealing unit from being separated from a cavity of an inner tool by fixing the sealing unit at a predetermined position. The inflatable sealing unit permits flexibility as the inflatable isolation tool can be used within a range of the wider diameter in a pipe. When gas is pumped at same time in the both sealing units by a single gas inlet of a share type pipe assembly, the tool is self-centered at a proper position in the pipe. So, the inflatable isolation tool can be rapidly installed and removed. An operable holding unit insert is clamped on the surface of the inner pipe and maintains stop of the tool. A support leg unit assembly helps installation and removal of the tool. A rear plate forms multiple port connection units. The tool is electronically monitored by the additional improved monitoring unit.
