HEAVY DUTY, CAST IRONSERIES 5000AND 7000SLUICE GATESGENERAL DESCRIPTION (continued)FRAMESThe cast iron frames are square or rectangular in shape, ofone piece construction and may have square, rectangular,or circular openings. Standard Flangeback, RectangularExtended Flangeback and Circular Extended Flangebacktypes are available.GUIDE RAILS AND WEDGESCast iron guide rails of a length sufficient to support at leastone-half of the slide when fully opened are cast integrallywith the frame on small and medium size gates and aremounted on fully machined surfaces with dowels andcorrosion resistant fasteners on the larger sizes. Wedgeblock pads are cast as a part of the guide rails and reinforcedwith heavy ribs. The wedge seal faces or adjustablewedge blocks are attached to these. A fully machinedgroove to receive the slide tongue extends the full lengthof each guide. Guides are extra heavy and reinforced fortheir full length to assure maximum rigidity against wedgingpressure and unseating heads when the slide is partiallyopen.SLIDEThe cast iron Slide (Cover) has vertical and horizontalreinforcing ribs, a heavy square nut pocket cast integrallywith the slide, and a machined guide tongue extending thefull length of each side. Minimum tolerances are maintainedbetween the slide tongue and guide grooves toprovide maximum stability of the slide in partially openpositions, thus minimizing chatter. Gates with Non-RisingStems are furnished with a special slide having a heavythrust nut pocket cast integrally with the slide. This pocketis located above the opening of the gate so that at no timewill the stem protrude into the waterway. The thrust nut inthe slide pocket is not secured to the stem and acts as a liftnut as the stem is rotated.SEATSSeating faces are of a corrosion resistant material and aresecured in full width dovetail grooves machined in the castiron frame and slide (see material schedule for alloysavailable). Seat facings are of a work hardening malleabletype and are deformed and locked into place in the grooveswithout the use of fasteners. An accurate and positiveattachment is obtained with the grooves completely filled.The full width dovetail design eliminates the possibility ofleakage between the corrosion resistant seat material andthe castings. The full width dovetail design of the seatingfaces prevents damage to these faces which may occur indovetail designs having overhangs which may work looseduring normal operation of the gate. (See detail drawing)S-7000JOBSITE HANDLING AND INSTALLATIONTo assure proper operation of our gates, care must betaken in the receiving, handling, and storage of all gatesand appurtenances. Installation must be accuratelyperformed. See the Waterman Heavy Duty Sluice GateInstallation Manual for complete detailed instructions.Waterman Heavy Duty Sluice Gates are completelyassembled in the plant and are given an AWWA C-501inspection by qualified inspectors before shipment.This includes operational, visual and feeler gaugetests. Seat clearance must not pass a .004 gauge.When required, a hydrostatic test can be performedbefore shipment at an extra charge. Waterman gates,properly handled, stored and installed should meetthese same standards in operation.Cross SectionSluice Gate Frame and CoverIndustries4
