SEWAGE STIRRING VALVE AND PUMP UNIT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sewage stirring valve avoiding environmental pollution caused by oil. SOLUTION: The sewage stirring valve is formed with an inflow port into which sewage flows, an outlet port from which the sewage is discharged and a conduit guiding the sewage from the inlet port to the outlet port. The sewage stirring valve is formed with a first elastic film disposed on a position opposite to the inflow port, a hollow section disposed to the elastic film on the side opposite to the inlet port and a ball valve disposed downstream of the elastic film and upstream of the hollow section and capable of moving back and forth in the conduit. A damper capable of extending and shrinking according to the deformation of the film, a link mechanism disposed above the damper and vertically moving in conjunction with the extension and shrinkage of the damper and a second elastic film disposed to shut off the conduit and the hollow section from each other above the link mechanism and making displacement in conjunction with the vertical movement of the link mechanism are provided in the interior of the hollow section. The ball valve is moved vertically through the second elastic film. COPYRIGHT: (C)2007,JPO&INPIT
