摘要： Butterfly valve plate sealing assemblies are provided that include a sealing ring and a retention spacer disposed at least partially within a sealing ring groove formed about a periphery of a butterfly valve plate. The sealing ring includes a first portion, a second portion configured substantially perpendicular to the first portion, and a substantially L-shaped cross-section. The sealing ring is positioned at least partially within a groove opening and a groove body defining the sealing ring groove. The retention spacer is positioned at least partially within the groove opening and adjacent the first portion of the sealing ring. The retention spacer is configured to limit expansion of the sealing ring when under the influence of a pressurized fluid flow. The second portion of the sealing ring may be configured to optimize stiffness for a desired sealing ring tension.
摘要翻译：提供了蝶阀板密封组件，其包括密封环和至少部分地设置在围绕蝶阀板的周边形成的密封环槽内的保持间隔件。密封环包括第一部分，基本上垂直于第一部分构造的第二部分和大致L形的横截面。密封环至少部分地位于沟槽开口和限定密封环槽的槽体内。保持间隔件至少部分地位于槽开口内并且邻近密封环的第一部分。保持间隔件构造成在加压流体流动的影响下限制密封环的膨胀。密封环的第二部分可以构造成优化用于期望的密封环张力的刚度。
