Unitary Diaphragm

摘要

Disclosed are systems and methods for a unitary diaphragm assembly is for use in flush valves. The diaphragm assembly may have a flexible diaphragm which includes a seating portion and a mounting portion at the outer peripheral edge. A flow ring may be positioned adjacent to the seating portion of the diaphragm. An elongated barrel member may extend from the diaphragm in a longitudinal direction and may include a plurality of radial supports positioned circumferentially around the outer surface of the barrel member and along a portion of the length of the barrel member.

1. A one-piece unitary diaphragm assembly for use in a flush valve, the assembly comprising:
an elongated barrel member having a body defining a passageway; an annular flexible diaphragm disposed about the elongated barrel member, and a mounting portion at the peripheral edge of the annular flexible diaphragm for mounting said diaphragm assembly within the flush valve; a radial support positioned circumferentially around the outer surface of said barrel member and extending along at least a portion of the longitudinal length of said barrel member; a relief valve seat at the upper end of said elongated barrel member, said relief valve seat adapted for receiving a relief valve; wherein the elongated barrel member is constructed of a first predetermined material; and wherein the annular flexible diaphragm is constructed of a second predetermined material different from the first predetermined material.
