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
(i) moves into an alignment position with the inlet and the outlet in order to allow passage of media through the valve or (ii) moves to a nonalignment position with the inlet and the outlet in order to block the valve; (c) one or more valve seals positioned at an interface between the valve housing and the flush plate; wherein the inlet comprises inwardly angled side walls that comprise a leading edge farthest from the flush plate in use, wherein the leading edge provides a narrowed channel for incoming flow of media 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.
