초록 ▼

An apparatus for sealing a movable closure member about an access aperture located within a rigid structure. The movable closure member is sized to cover the access aperture and to provide access through the access aperture when open. A resilient elastomeric gasket is secured to one of the rigid structure or the movable structure to suit design and manufacturing preference. The resilient elastomeric gasket has a hollow cavity disposed within the elastomeric gasket, and the hollow cavity is sealed at each end to form a pressure-equalizing chamber therein. A convex protrusion is positioned on the elastomeric gasket to confront a flat stop positioned upon the other of the rigid structure or the movable structure when the movable structure is closed. A closure means is provided to bias the convex protrusion against the flat stop face with sufficient pressure to partially deform the resilient, elastomeric gasket. The elastomeric gasket and the flat stop may be retrofited onto existing water tight doors by securing the flat stop onto the knife edge; and by replacing the existing seal with the elastomeric gasket of the present invention. This invention is adapted for use on bulkhead type fluid tight doors, and upon fluid tight double opening doors, and hatch covers.

An apparatus for sealing a movable closure member about an access aperture in a rigid structure, which comprises: a) a movable closure member sized to cover the access aperture when closed, and to provide access through the access aperture when open; b) a resilient, elastomeric gasket secured to the movable closure member about the access aperture, with a convex gasket protrusion extending about the access aperture in confronting relation to the rigid structure surrounding the access aperture; c) a flat stop face positioned on the rigid structure to abut the convex gasket protrusion as the movable closure member is closed; d) a closure means for biasing the convex gasket protrusion against the flat stop face with sufficient pressure to at least partially deform the convex gasket protrusion by means of a precompression force exerted by the closure means as the convex gasket protrusion is biased against the flat stop face; and e) a hollow cavity disposed within the elastomeric gasket beneath the convex gasket protrusion, the hollow cavity sealed at the ends to provide an internal equalizing fluid pressure substantially about the access aperture to provide a uniform force distribution between the flat stop face and the convex gasket protrusion.
