Title: Device for cleaning inside surface of pipeline - has elements to detect its position when it is blocked in pipe-line
Inventor: GOERLITZ FRANK-OTTO DIPL ING
IPC: B08B9/055
Filed: 1991-04-09
Abstract: A device for cleaning the inside surface of a pipe-line, has a cylindrical body (7) with a circular plate (3) attached to each end. The circular plates (3) have circumferential grooves to receive sealing rings (6). The cylindrical body houses a piston (9) which is pressed by a spring (11) against the rear end plate (3) so that an inlet hole (14) is closed by a projection on the end face of the piston. The device is driven along the pipe-line by compressed air. If the device strikes an obstacle the pressure on the rear face increases and presses the piston against the spring so that it is clear of the hole (14) and permits the free passage of air when the piston has been pushed beyond the radial holes (16) in the cylinder wall. The pressure then falls until the hole (14) is closed, and the cycle repeated, so that a vibration is generated which serves to detect the position of the device when a blockage occurs. USE/ADVANTAGE - Pipe-line cleaning device with means to detect its position.
