Heat-activated expandable seal and method for producing same

A seal ( 10 ) includes a hot-melt polymer ( 12 ) with a foaming agent, and a heating agent ( 18 ) for providing heat to at least partially melt the hot-melt polymer ( 12 ) and to activate the foaming agent. A heat conductive barrier ( 16 ) is disposed between the hot-melt polymer ( 12 ) and the heating agent ( 18 ) to inhibit mixing of the heating agent ( 18 ) with the hot-melt polymer ( 12 ). This reduces the likelihood that the hot-melt polymer ( 12 ) will burn if the heating agent ( 18 ) produces a large quantity of heat, and also helps to ensure that the hot-melt polymer ( 12 ) will be uncontaminated by the heating agent ( 18 ) and will therefore form an effective seal. When the foaming agent is activated by the heat, it produces gas to expand the partially melted hot-melt polymer ( 12 ) to fill gaps and form an effective seal.

The preferred composition is 5 to 70% by weight of unexpanded graphite and 30 to 95% expanded graphite, wherein the percentage of unexpanded graphite is controlled to provide the desired gasket expansion. A more preferred composition includes at least 10% by weight unexfoliated graphite or more preferably 15 to 50% by weight. The gasket is placed between the surfaces to be sealed and clamped in place. When the joint is heated, the unexpanded graphite exfoliates, causing the gasket to swell or expand, tightly sealing the joint. The expandable gasket of this invention is particularly suitable for automotive application, including head and exhaust gaskets which are subject to temperatures exceeding about 400° C.

Bumps are positioned in axial alignment with the seals but in opposition to each seal so that the exterior seal has a bump axially aligned but on the inside of the ring and the inner seal has a bump axially aligned and on the outside surface of said ring. The bumps have end transitions to the base dimension to create a volume for the seal material to travel axially when radially expanded from a mandrel extending within for effective seal containment. Seal rings can be stacked to adjust to dimensional irregularities in the surrounding tubular or the mandrel and to back each other up in the event of seal failure in any one seal ring.

Sealing device for an annular space between a pin and housing wall - consisting of sealing ring and inner expandable O=ring for the exclusion of water or fluid, allowing pin to move freely

A device for the sealing of an annular space between a duct (42) in a wall (40) and a pin or bolt (50) that extends through the duct. The sealing device consists of a ring seal (46) whose surface (62) adjoins the bolt (58). In the ring seal (46) is a circular groove (50) in which an O-ring (56) is held. The O-ring (56) is made of absorbing material, which on contact with water expands outwards in the radial direction. As a result, the ring seal (46) is deformed so that its surface (62) pushes against the bolt (58) and seals it. USE/ADVANTAGE - Used in military assemblies, such as mines, where the safety and detonation pins extend outwards from the mine housing and in the course of use are moved inwards and outwards. Prevents the entry of water or other fluids while same permitting easy movement of the pin or bolt.

Profile, for sealing joints in concrete structures, is a tube filled with a material which expands with water to fill the joints and seal them

The profile, to seal joints in concrete structures, is a hollow tube filled with a material which swells in water. The tube, of a modified collagen, is permeable to water and is expanded by inner pressure and it can burst. The filling is a sheet silicate containing sodium or calcium bentonite with a slow swelling action when the tube is immersed in water.

Large-gap-seal ("lgs") assembly

A large-gap-seal ("LGS") assembly (30) and methods for its assembly and use are described. The LGS assembly (30) has an elastomer core (50) surrounded by adjoining structural segments (70). Non-adjoining gap segments (60) are located on the sidewall surfaces (55) of the elastomer core (50), with each gap segment (60) approximately centered beneath the edges of two adjoining structural segments (70). The gap segments (60) are exposed by the spaces that form between the structural segments (70) when the LGS assembly (30) is activated. Exposing the gap segments (60) rather than the elastomer core (50) protects the elastomer core (50) from damage and preserves the integrity of the seal between the isolation tool (20) and the inner wall of the pipeline.

Fluid-activated shaft seal

Systems and methods associated with a fluid-activated shaft seal are provided. The system (100) includes a housing (104) and a seal disposed relative to the housing. The method reduces flow of a fluid between the shaft (102) and the housing. The method involves installing the housing in an opening relative to the shaft and locating the seal relative to the housing. The seal includes a gel material that expands when exposed to a fluid. The seal (102a, 102b) reduces flow of the fluid through a gap between the housing and the shaft. Advantages of the system and method include reduced wear to the seal due to friction because the seal does not engage the shaft in the absence of a fluid. The seal engages the shaft in the presence of a fluid. Sealing quality is improved by increasing the pressure differential acting on the gel material. In some embodiment, the seal includes a lip portion (126a, 126b).
