Device for checking the internal geometry of pipes

摘要

The invention relates to a device for checking the internal geometry of pipes, having a measurement gauge (6) which is blown through by blowing an air current through the pipe (1) to be checked. In this case, a device (11) is provided for reversing the pressing air current into a sucking air current, and an adapter piece (5) which can be connected in a leakproof fashion to one end of the pipe (1) accommodates the measurement gauge (6), the adapter piece (5) being connected to a line (7) for the air current. Furthermore, a buffer and stop device (13) is arranged in front of the other end of the pipe (1) to be tested, on which a switchover contact (12) is provided via which the device (11) is operated to reverse the air current. <IMAGE>
