Title: Cleaning device for sewer pipe and drain pipe
Inventor: NAGATA HIDEYUKI
IPC: E03C1/304
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to remove washingly away filth deposited or precipitated on the inner surface of a pipe with water pressure of a cleaning solution by blowing out the cleaning solution supplied to a water supply pipeline from a blow-out opening and providing this blow-out opening in the inner surface of a sewer pipe and a drain pipe or in the peripheral wall extendingly in the longitudinal direction. SOLUTION: When a threaded stem 12 is screwed in and pushed down until and internal butterfly check valve 8 shuts down a communication opening 6 on the upstream side so as to shut down a water supply pipeline with a switch 4 and the threaded stem 12 is removed from a screw hole and the screw hole 11 is opened, this screw hole 11 will serve as an intermediate water supply opening. When is cleaning solution is fed from here, the butterfly check valve 8 shuts down the communication opening on the upstream side without receiving the depressed pressure from the threaded stem and shuts down the water supply pipe 3.  A drop in the water pressure can be prevented by feeding the cleaning solution 14 to the water supply pipeline segmented with the switch 4 so that the cleaning solution 14 may spout out vigorously from a blow-out opening 3a provided on the water supply pipeline and blown to the inside bottom of a sewer pipe 2.
