Three-way pieces with non-return or interchangeable flaps, including those with armored inserts the various building materials of ceramic and metallic nature to reduce the Pipeline wear, in particular in the case of flushing offset processes, is known per se. In the case of the embodiments similar to the invention, it has not been possible to prevent that near the edges of the built

ο Armored inserts as a result of the sealant being washed out by the formation of eddies severe scouring and erosion of the pipe walls occurred.

The invention relates to a novel embodiment of the attachment of the such three-way pieces are often necessary in the area of the interchangeable or non-return valve Armored inserts. The attachment of these deposits has so far been carried out by at most specially sealed screws or ao rivets. The progress of the invention lies in that the armored inserts built into a two-part housing in one Grooves recessed in the housing part are designed to be insertable and can be positioned without any wan partially mutually support through opening and overall through the second Housing part are held together.

The drawing illustrates an embodiment of an armored three-way

Stückes.mit interchangeable flap according to the conception with horizontal subdivision of the three-way piece at the level of the axis of the interchangeable flap, namely

ίο Fig. i,

Fig. 3 is a horizontal section according to bb of Fig. I,

Fig. 4 is a horizontal section according to cc of Fig. I.

On the lower housing part 1 sits - connected by means of flanges - the upper part 2. The horizontal division between the housing parts 1 and 2 is such that the interchangeable flap axis 5 with its associated

Stuffing boxes and the interchangeable flap 6 when removing one or the other component of the three-way piece becomes free.

Covering the swivel range of the interchangeable flap 6, parallel to its longitudinal

s5 sides the armor inlays 3 in the grooves Walls inserted that they are also in grooves in the walls of the pipe part 2 hold the flap stop strips 4 in place. The inserts 3 are through the

Pipe section 1 secured in position after screwing together with the housing part 2. The interchangeable flap 6 is mounted by means of its axis 5 with stuffing boxes inserted between the flanges of the housing parts ι and 2 so that the gap at d between the pipe wall and the cylindrical flap back at its respective entrance is designed so that it seals itself by fine material carried along without but thereby to hinder the movement of the flap. The flap can be moved using a hand lever, hand wheel, worm wheel and worm or the like.

When using the three-way piece as a non-return valve in unifying pump lines the flap must be provided with appropriate seals.
