Device for interrupting the flow in a fluid conveying pipe

摘要

The interruption obturator is installed on a pipe (1) with two unions (3). The first of these unions at least has an appropriate joint (4) and one or both of the unions are equipped with a pierced flange. The axis of the pierced flange (6) has an axle (7) which is the point around which a cutting blade (2) can turn. This cutting blade (2) follows a circular movement determined by the interruption positions and circulation of the flow.
