초록 ▼

A coupling apparatus includes first and second coupling members each having the form of a hollow conduit having a radially extending flange at a first end, an axially extending sleeve defining a second end adapted to connect with a fluid transport fitting, and a fluid transport passageway running axially therethrough. Each flange has a generally planar axially facing frontside surface. In one embodiment, the frontside surface of the first coupling member flange has at least one integral tongue extending axially outwardly therefrom, and the frontside surface of the second coupling member flange has at least one groove disposed axially therein. Each tongue is placed within a respective tongue to form a liquid-tight seal when frontside surfaces of the first and second coupling member flanges are joined together. In another embodiment, the frontside surfaces of each first and second coupling flange include at least one groove disposed axially therein. At least one seal ring independent from the flanges is interposed between adjoining frontside surfaces so that axially facing edges of the seal ring placed within respective grooves to form a liquid-tight seal when the frontside surfaces of the first and second coupling member flanges are joined together. The frontside surfaces are held together by a nut installed over the first and second coupling member flanges.

A coupling apparatus comprising: first and second coupling members each in the form of a hollow conduit and each comprising: a radially extending flange having an axially facing frontside surface at a first end of each coupling member; a sleeve extending axially away from the flange to a second end of each coupling member that is adapted to accommodate attachment with a fluid handling member; and a fluid flow passageway extending through the coupling member from the first to the second end; wherein the frontside surface of the first coupling member flange includes at least one tongue that projects axially a distance outwardly away from the frontside surface and is positioned concentrically around the passageway, the tongue having non-tapered radially directed surfaces; and wherein the frontside surface of the second coupling member flange includes at least one groove disposed therein that is positioned to accommodate placement of a respective first coupling member tongue therein, the groove having non-tapered radially directed surfaces and a radial width between non-tapered radially directed surfaces that is less than a radial width of the tongue, and the tongue having an axial length that is greater than an axial length of the groove, the differences in radial width and axial length of the tongue and groove providing an interference fit therebetween that forms a liquid-tight seal between the first and second coupling members when the frontside surfaces of the first and second coupling member flanges are brought together; and means for maintaining frontside surfaces of the first and second coupling member flanges joined together.
