ABSTRACT:
A device for closing a pipe branch, especially for closing either orifice of a Y-shaped distributor connection, which is to close the inflow of the unoccupied flow-off in a gastight and watertight manner, is proposed. At the same time, there will be the possibility of mixing the medium for all the connections. To achieve this object, for this purpose either branching-off junction connection is made closeable by means of a common rotary plug, the rotary plug being designed as an oblique cylinder section (see the drawing for this).
