发明名称 Plug for Setting in a Pipe
摘要 A pipe plug comprising a shaft, a force transmission body disposed in a rotatable and axially movable manner about the shaft via a thread connection, and a stop body. Between the force transmission body and the stop body there is a first compression body disposed in an axially movable manner about the shaft in proximity of the force transmission body; a conical support body disposed in an axially movable manner about the shaft; at least one movable anchoring body on the outside of the support body; a second compression body disposed in an axially movable manner about the shaft; and at least one elastic sealing body disposed about the shaft. The shaft and the first compression body are in direct contact with each other and are connected in a non-rotational manner via complementary connection elements to prevent the compression body from rotating.
