    摘要: A degassing valve in a flexible container is disclosed. The valve includes a generally flat valve seat on a truncated generally dome shaped structure, and the valve seat is raised a height above the valve chamber base surface. A resilient, non-perforated, non-spring-biased diaphragm is inter-engaged upon the valve seat and overlaps the valve seat outer periphery. The valve seat engages a central area of the diaphragm that is not proximate the perimeter of the diaphragm, and the dome shaped structure has a sectional radius greater than the diaphragm radius. A well is recessed into the valve seat in a direction away from the diaphragm by a depth less than the height of the valve seat above the valve chamber base surface.

    摘要: A pressure relief valve for use with flexible containers is disclosed. The valve comprises a valve chamber, a valve chamber seat with an inlet gas port or ports to the interior of the container and a resilient diaphragm floating within the chamber. The valve seat is shaped with a generally flat diaphragm-engaging surface in a central area of the diaphragm where the inlet gas port(s) are located, and at least one surface that does not generally engage the outer portion of the diaphragm, such that a diaphragm floating in the valve chamber engages a central portion of the valve seat surface stopping the passage of gases in or out of the container before a certain pressure is reached, but permitting the passage of gases from within the flexible container as pressure builds, while preventing the flow of atmospheric gases into the container.
