Abstract

The shut-off consists of an inflatable balloon (4) which is equipped with an asymmetrical element (6) opposite its opening to deploy it inside the pipe. The element can be connected to the end of a flexible rod (10) which passes through the middle of the balloon. The balloon can be inserted through a branch (2) fixed to the pipe at right angles, designed to receive a movable tube (15) with a hollow bar (9) inside it for inflating the balloon. The tube has an outer diameter which is slightly smaller than the inner diameter of the branch, and there is a seal (14) between the tube and the hollow bar. During operation the asymmetrical element interacts with the inner surface of the pipe when inserted, and takes the balloon to one side of the insertion point, where it can be inflated. <IMAGE>
