Abstract
A flange assembly adapted to be used in a gasket having an opening with an inner peripheral boundary including two flanges. Formed using a generally non-malleable metal, the flanges generally correspond to the shape of the boundary of the gasket body opening. Each of the flanges include a radially outer edge and a radially inner edge, an inner surface of each of the flanges adapted to be secured to the gasket body. The flanges may be mechanically or chemically secured to the gasket body. In one embodiment, the flange assembly includes a separate sealing element such as a wire ring. The inner edges of the flanges extend inwardly of the boundary of the gasket body to define a channel adapted to receive the sealing element.
Claims21
A gasket used in high temperature operation comprising:
- a gasket body with an upper surface and a lower surface having at least one opening, said opening having an inner peripheral boundary;
- and
- a flange assembly with two flanges generally shaped to correspond to said boundary disposed adjacent said boundary, said flange assembly including an upper flange with a radially outer edge and a radially inner edge, an inner surface of said upper flange engaging said upper surface of said gasket body, and a lower flange with a radially outer edge and a radially inner edge, an inner surface of said lower flange engaging said lower surface of said gasket body, each of said upper and lower flanges being secured to said gasket body, wherein a plurality of tabs extend radially outwardly from said outer edge of at least one of said flanges, a mechanical fastener being used in conjunction with a number of said tabs to secure said at least one of said flanges to said gasket body.
A gasket used in high temperature operation comprising:
- a gasket body with an upper surface and a lower surface having at least one opening, said opening having an inner peripheral boundary;
- and
- a flange assembly with two flanges generally shaped to correspond to said boundary disposed adjacent said boundary, said flange assembly including an upper flange with a radially outer edge and a radially inner edge, an inner surface of said upper flange engaging said upper surface of said gasket body, and a lower flange with a radially outer edge and a radially inner edge, an inner surface of said lower flange engaging said lower surface of said gasket body, each of said upper and lower flanges being secured to said gasket body, wherein a plurality of circumferentially spaced tabs extend radially outwardly from said outer edge of said flanges, a mechanical fastener being used in conjunction with a number of said tabs to secure said flanges to said gasket body, and said number of said tabs of said flanges aligned on opposite sides of said gasket body so that said mechanical fastener engages a corresponding aligned tab of said each of said flanges.
A flange assembly adapted to be used in a gasket with a gasket body having an opening with an inner peripheral boundary, said flange assembly comprising:
- an upper flange generally corresponding to the shape of the boundary of the gasket body, said upper flange having an outer edge and an inner edge, and wherein an inner surface of said upper flange is adapted to be secured to the gasket body;
- and
- a lower flange generally corresponding to the shape of the boundary of the gasket body, said lower flange having an outer edge and an inner edge, and wherein an inner surface of said lower flange is adapted to be secured to the gasket body, a plurality of circumferentially spaced tabs extending radially outwardly from said outer edge of said flanges.
A gasket used in high temperature operation comprising:
- a gasket body with an upper surface and a lower surface having at least one opening, said opening having an inner peripheral boundary;
- and
- a flange assembly with two flanges generally shaped to correspond to said boundary disposed adjacent said boundary, said flange assembly including an upper flange with a radially outer edge and a radially inner edge, an inner surface of said upper flange engaging said upper surface of said gasket body, and a lower flange with a radially outer edge and a radially inner edge, an inner surface of said lower flange engaging said lower surface of said gasket body, each of said upper and lower flanges being secured to said gasket body, said inner edges of each of said flanges extending inwardly of said boundary to define a channel, a sealing element extending about and being received in said channel, said flanges engaging said sealing element to retain said sealing element in position, wherein said sealing element is a wire ring.
A gasket used in high temperature operation comprising:
- a gasket body with an upper surface and a lower surface having at least one opening, said opening having an inner peripheral boundary;
- and
- a flange assembly with two flanges generally shaped to correspond to said boundary disposed adjacent said boundary, said flange assembly including an upper flange with a radially outer edge and a radially inner edge, an inner surface of said upper flange engaging said upper surface of said gasket body, and a lower flange with a radially outer edge and a radially inner edge, an inner surface of said lower flange engaging said lower surface of said gasket body, each of said upper and lower flanges being secured to said gasket body, wherein a plurality of tabs extend radially outwardly from said outer edge of at least one of said flanges.
