Sealing device for flanges
Gaskets for sealing two mating surfaces have an inner ring positioned between two inner sealing deformable layers and an outer ring positioned exterior and concentric to the inner ring, the outer ring positioned between two outer sealing deformable layers. The two inner sealing deformable layers are configured to compress a greater amount than the two outer sealing deformable layers when a compressive force is applied. In a compressed configuration, the two inner sealing deformable layers fill in the crevices of the mating surfaces of a corroded flange connection thereby avoiding immediate maintenance for the damaged flanges. The inner and outer rings have grooves and ridges on upper and lower surfaces to retain and receive portions of the inner and outer sealing deformable layers in a sealed flange connection. |

Zero restriction ball valve insert, one-piece cage and assembly
An improved one-piece cage and an improved insert and their assembly create a zero-restriction fluid flow ball check valve. The improved insert for ball and seat valve comprises external screw threads on the base of the insert and have circumferentially spaced ribs extending upwards and converging towards the longitudinal axis of the insert, forming a hemi-spherical ball stop and arched side openings. The inside diameter of the insert bore is substantially equal to the ball valve diameter preventing the ball from rattling when positioned in the improved insert's passageway during the fluid flow. The outside diameter of the ribs is less than the inside diameter of the improved one-piece cage cavity producing a zero-restriction fluid flow ball check valve in comparison to the volumetric fluid flow through the annular seat. The improved cage that receives the improved insert is a one piece in construction and has internal threads that correspond to the external threads on the improved insert. The insert is assembled inside the cage using a screw thread connection and simultaneously forming a fluid seal between the insert and the cage. |
