Title:
PIPE-BRUSHING DEVICE
Document Type and Number:
Japanese Patent JPS6051586
Kind Code:
A
Abstract:
The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure. The rear Inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion. The valve has a cage bearing a rear plate closure, and open sides and front. The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate. The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state. However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving resrwardly in the groove to cause a mechanical vibration in the tubular member and water pipe. Waterthen by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog. Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe. The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vib ate the pipe to unclog the pipe.
