Solids-handling equipment

摘要

A closure component (10) for solids-handling equipment includes a closure body (12) configured to close a solids flow path by displacement of the closure body (12) along a stroke axis (20) and a removable metallic sealing element (14) attached to the closure body (12). The metallic sealing element (14) is configured sealingly to engage an endless metallic seat spaced radially outwardly from the stroke axis (20) when the closure body (12) closes the solids flow path. The closure body (12) includes or defines at least one locating formation (34) to engage and locate the metallic sealing element (14). The least one locating formation (34) is positioned radially outwardly from the stroke axis (20) and more radially outwardly from the stroke axis (20) than at least a portion of the metallic sealing element (14) so that at least a portion of the metallic sealing element (14) is positioned between the locating formation (34) and the stroke axis (20), thereby correctly to locate the metallic sealing element (14) in position relative to the closure body (12) or relative to the stroke axis (20) during fitting of the metallic sealing element (14) to the closure body (12).
