Abstract:
A flexible-seal sluice gate comprising:a sluice-gate wall that encompasses a sluice-gate aperture;the sluice-gate aperture having an aperture axis to which the sluice-gate wall is orthogonal;a sluice-gate plate having a closure surface that is sized, shaped and structured to be juxtaposed to an arcuate sealing surface of a domed seal ring that is positioned removably intermediate the sluice-gate wall and the sluice-gate plate;the domed seal ring having at least one dome flange that is disposed oppositely from a domed sealing surface on the domed sealing ring;the at least one dome flange bracket having at least one bracket plate that overlays the dome flange to fasten the at least one domed seal ring removably intermediate the sluice-gate wall and the sluice-gate plate;a plate locator that is structured to set the sluice-gate plate in predetermined sealing-contact for predetermined structure of the flexible-seal sluice gate; anda valve vice having structure for forcing the sluice-gate plate in a direction towards the sluice-gate wall for a closed mode and for moving the sluice-gate plate in a direction away from the sluice-gate wall for an open mode of the predetermined structure of the flexible-seal sluice gate and wherein the plate locator is lateral to the aperture axis with a plurality of bevel hooks;the bevel hooks have wall bevels on the sluice-gate wall and plate bevels on the sluice-gate plate;the wall bevels are beveled in a direction away from the sluice-gate plate and downward from wall-bevel edges on the sluice-gate wall;the plate bevels are beveled in a direction away from the sluice-gate wall and upward from gate-bevel edges on the sluice-gate plate;the valve vice is a lateral forcer having lateral-force anchorage that is common to anchorage of the sluice-gate wall, andthe lateral-force anchorage of the lateral forcer is orthogonal to the axis of the sluice-gate aperture.
