Reinforced elastomeric diaphragm
A diaphragm is provided that includes a plurality of zonal portions that define reinforced and non-reinforced areas of the diaphragm. A first zonal portion extends from a marginal edge portion toward a central portion and is formed of a fabric material. A second zonal portion extends from the first...

| Zusammenfassung: | A diaphragm is provided that includes a plurality of zonal portions that define reinforced and non-reinforced areas of the diaphragm. A first zonal portion extends from a marginal edge portion toward a central portion and is formed of a fabric material. A second zonal portion extends from the first zonal portion toward the central portion and is formed of an elastomer. A third zonal portion defines the central portion and is formed of a fabric material. The combination of reinforced and non-reinforced portions provides for a decrease in the radial tension (spring rate) of the diaphragm and helps prevent undesired changes to the flow control valve flow setpoint. |
