Abstract: A slide gate has a frame made up of parallel channel guides extending vertically from and cooperating with a horizontal bottom to define a gate opening. The channel guides each have mutually spaced first and second guide flanges protruding laterally into the gate opening. A gate disc is supported by the frame for vertical movement between a lowered position resting on the frame bottom and closing off the gate opening, and an open position spaced thereabove. The gate disc has side portions received between the first and second guide flanges of the channel guides, and these side portions carry seal assemblies. A plurality of vertically spaced pivotal pressure pads are mounted on each of the channel guides between their respective first and second guide flanges.

Abstract: A sluice gate assembly has a metal frame surrounding an opening and a metal gate disc mounted for movement between open and closed positions along guides on the frame. The gate disc carries a resilient deformable seal which cooperates in sealing engagement with a plastic seat face on the frame when the gate disc is in the closed position. The sealing interface between the resilient deformable seal and the plastic seat face is arranged at an angle relative to the line of travel of the gate disc along the guides, and the guides are mounted for adjustable movement towards and away from the frame seat face.

Abstract: A sluice gate assembly has a resilient seal member mounted on the gate disc for movement therewith relative to a stationary frame. The frame has seat facings against which seat facings on the gate disc are urged when the gate disc is seated in the closed position. The resilient seal member is normally spaced from the frame and its seat facings when the gate disc is in other than the seated closed position. As the gate disc is seated in the closed position, a wedge-actuated seal retainer exerts a force on the resilient seal member to deform it against the frame seat facings.

Abstract: A sluice gate assembly is disclosed which includes a single-flange cast frame, a pair of elongated grooved gate disc guides mounted on the frame, a gate disc slidably supported by the grooved gate disc guides for vertical movement between a raised open position and a lowered closed position, and a wedge system for wedging the gate disc into sealing engagement against the frame when the gate disc is in its lowered closed position.
