    • Embodiments of the present disclosure are directed toward a pressure vacuum relief valve and a seal assembly of the pressure vacuum relief valve. The seal assembly includes a ribbed substrate disposed against a flanged seat of the pressure vacuum relief valve. The ribbed substrate includes ribs extending from a base of the ribbed substrate. The seal assembly also includes a pallet coupled to and disposed below the ribbed substrate. The pallet includes a top ring, a bottom ring, and a flexible diaphragm captured between the top ring and the bottom ring. The flexible diaphragm of the pallet is configured to seal against the ribbed substrate in a sealed position. The pallet and ribbed substrate are configured to move together away from the flanged seat when a pressure on a sealed side of the pressure vacuum relief valve exceeds a maximum pressure threshold. The pallet is also configured to pivot open at an angle relative to the sealed position of the pallet when the pressure on the sealed side of the pressure vacuum relief valve falls below a minimum pressure threshold.
    • 本公开的实施例涉及压力真空释放阀和压力真空释放阀的密封组件。 密封组件包括设置在压力真空释放阀的法兰座上的肋状衬底。 肋状基板包括从肋状基板的基部延伸的肋。 密封组件还包括联接到并布置在肋状基板下方的托盘。 托盘包括顶环,底环和捕获在顶环和底环之间的柔性隔膜。 托盘的柔性隔膜构造成在密封位置密封肋状基板。 当压力真空溢流阀的密封侧的压力超过最大压力阈值时,托板和肋状基板被构造成一起移离法兰座。 当压力真空溢流阀的密封侧的压力低于最小压力阈值时,该托盘也构造成相对于托盘的密封位置以一定角度枢转打开。
