摘要
Waste liquid is discharged into a pneumatic sewage disposal system from a drain conduit into which such liquid flows from a place in a kitchen or laundry or a fixture in a bathroom like a bathtub or wash basin, for example. A main valve of valve structure, which is operatively associated with the drain conduit for controlling flow of waste liquid into the sewage system, moves from its closed position toward its open position and back to its closed position with increase and decrease, respectively, in the hydrostatic pressure of waste liquid in the drain conduit.
