MIXED MEDIA ORBITAL VALVE

摘要

Embodiments of the invention described herein thus provide improved flush valves that are designed with improved venting features and improved inlet designs. The described venting features and inlet designs, either alone or in combination, can help prevent ingestion of waste into the interior of the valve.

主权项

1. A mixed media orbital valve, comprising:
(a) a valve housing comprising an inlet and an outlet; (b) a flush plate housed within the valve housing and interposed between the inlet and the outlet, the flush plate having a media bore hole that, when actuated, either rotates (i) into an alignment position with the inlet and the outlet in order to allow passage of media through the media bore hole or (ii) to a nonalignment position with the inlet and the outlet in order to block the media bore hole; (c) one or more valve seals positioned at a seal interface between the valve housing and the flush plate; (d) a venting system comprising a first vent positioned such that it remains unimpeded by any actuation of the flush plate, and a second vent positioned adjacent the seal interface of the flush plate and the one or more valve seals.
