Title:
MIXED MEDIA ORBITAL VALVE
Document Type and Number:
WIPO Patent Application WO/2014/151319
Kind Code:
A3
Abstract:
A mixed media orbital valve comprises a valve housing (1) with an inlet (3) and an outlet (4), a flush plate (2) housed within the valve housing and interposed between the inlet and the outlet, and one or more valve seals (8) positioned at an interface between the valve housing and the flush plate. The flush plate has a media bore hole (14) that, when actuated, either moves into an alignment position with the inlet and the outlet in order to allow passage of media through the valve, or moves to a nonalignment position with the inlet and the outlet in order to block the valve. The inlet (3) comprises shaped walls (9) such that the inward flow of media avoids a gap that is created between the one or more valve seals and the flush plate during actuation of the flush plate which helps in preventing ingestion of waste into the interior of the valve. Furthermore, vents (10, 11) are provided to prevent a pressure differential that could encourage media ingestion between the valve seals and the flush plate during actuatino of the flush plate.
