Abstract

A slide gate has a frame assembly with a pair of side guides, a bottom member and a top member that define an opening through which fluid flows. A movable slide plate is mounted to the frame assembly and constrained for movement between unblocking and blocking positions for regulating fluid flow through the opening. A side seal, which is seated within each side guide of the frame assembly, has a lip seal portion and bulbous portion, the side margins of the slide plate being received in sealing engagement between the lip seal portion and the bulbous portion. A bottom seal, which is seated in the bottom member, has a flat sealing surface which is in sealing contact with the bottom of the slide plate when the gate is closed. An adjustable lip seal, which is seated in the top member, is in sealing contact with the slide plate.

Dependent claims

A slide gate mechanism for controlling fluid flow through an opening in a wall, said slide gate mechanism comprising:

(a) a frame assembly having first and second gate guide members for disposition along the sides of said opening and at least a third gate guide member extending between said first and second gate guide members for disposition along the bottom of said opening, said third gate guide member interconnecting said first and second gate guide members;
(b) a slide plate locked between said first and second gate guide members and constrained for limited movement relative to said first and second gate guide members;
(c) operating means carried by said frame assembly and connected to said slide plate, said operating means being operable to selectively move said slide plate in one direction or an opposite direction relative to said first, second and third gate guide members so that said slide plate may be disposed in blocking or unblocking relation with said opening;
(d) first seal means associated with said first and second gate guide members, each of said first seal means including first lip seal means and resilient seal means, said first lip seal means engaging and pressing against the margin of one face of said slide plate, said resilient seal means engaging and pressing against the margin of an opposite face of said slide plate, the margins of said slide plate being received between said lip seal means and said resilient seal means;
(e) first adjustable retainer means received in each said first and second gate guide members, said first adjustable retainer means configured to be moved within each said first and second gate guide member for controlling the force exerted by said first seal means and said resilient seal means on said faces of said slide plate;
and
(f) second seal means seated in said third gate guide member for engaging the bottom of said slide plate when said slide plate is in its full blocking position, said second seal means in sealing relationship with said first seal means.

(d) first seal means seated in said first gate guide member, said first seal means including first lip seal means and first bulb means, said first lip seal means engaging and pressing against the margin of one face of said slide plate, said first bulb means for engaging and pressing against the margin of an opposite face of said slide plate, the margins of said slide plate being received between said first lip seal means and said first bulb means;
(e) second seal means seated in said second gate guide member, said second seal means including second lip seal means and second bulb means, said second lip seal means engaging and pressing against the margins of said one face of said slide plate and said second bulb means engaging and pressing against the margin of said opposite face of said slide plate, the margins of said slide plate being received between said second lip seal means and said second bulb means;
(f) third seal means seated in said third gate guide member for engaging the bottom of said slide plate when said slide plate is in its full blocking position, said third seal means in sealing relationship with said first and second seal means;
(g) fourth seal means seated in said fourth gate guide member for sealingly engaging said slide plate, said fourth seal means in sealing relationship with said first and second seal means;
(h) first adjustable retainer means adjustably mounted to said first gate guide member and received in said first seal means, said first adjustable retainer means configured to retain said first seal means in said first gate guide member and to bear against said first seal means for controlling the force exerted by said first lip seal means and said first bulb means against said slide plate;
and
(i) second adjustable retainer means adjustably mounted to said second gate guide member and received in said second seal means, said second adjustable retainer means configured to retain said second seal means in said second gate guide member and to bear against said second seal means for controlling the force exerted by said second lip seal means and said second bulb means against said slide plate.
