GOLDEN GATES MODEL GH-37 TIDE REGULATED FLAP GATE

DESCRIPTION OF OPERATION GOLDEN HARVEST, INC. GH-37 TIDE REGULATED FLAP GATE (patent pending)THE GH-37 OPERATES UTILIZING THE BASIC CONFIGURATION OF A NORMAL FLAP GATE AND MODIFYING IT TO PERFORM THE MORE DETAILED DUTIES OF TIDE BACK FLOW REGULATION. THE TASK OF BACK FLOW REGULATION IS CONTROLLED BY THE PRECISION PLACEMENT IN ELEVATION AND THE SIZING OF A SECONDARY FLAP ON THE PRIMARY FLAP GATE. THE OPENING AND CLOSING RATES OF THE SECONDARY FLAP ARE CONTROLLED BY A SERIES OF FLOAT DEVICES THAT ARE ADJUSTABLE TO CONTROL THE EVENT TIMING. THE SERIES OF CYCLES THAT THE REGULATING GATE OPERATES THRU ARE: (WITHOUT AUTOMATIC LOCKING OPTION) 1. PRIMARY FLAP IN THE NORMAL POSITION OF ALLOWING THE WATER FROM THE AREA BEHIND THE FLAP GATE TO OUTFLOW. 2. AS THE TIDE RISES IT WILL REACH THE ELEVATION OF THE BOTTOM OF THE SECONDARY FLAP. AT THIS TIME THE FLAP WILL OPEN AS THE TIDE RISES UNTIL IT ACHIEVES ITS PREDETERMINED ELEVATION. 3. AFTER THE SECONDARY FLAP IS FULL OPEN THE TIDE CONTINUES TO RISE AND WILL COME INTO CONTACT WITH THE CLOSURE FLOATS AT A PREDETERMINED ELEVATION. 4. AS THE TIDE CONTINUES TO RISE IT WILL LIFT THE CLOSURE FLOATS AND THEY IN TURN WILL CLOSE THE SECONDARY FLAP, THERE BY STOPPING TIDAL IN FLOW. 5. THE TIDE MAY NOW RISE TO A GREATER ELEVATION AND THERE WILL BE NO INFLOW AS BOTH FLAP GATES ARE CLOSED. 6. AFTER THE HIGH TIDE EVENT HAS BEEN REACHED THE TIDE BEGINS TO FALL. AS THE TIDE FALLS IT WILL RELEASE THE CLOSURE FLOATS AND THE SECONDARY FLAP WILL BEGIN TO OPEN. THE SECONDARY FLAP WILL REMAIN OPEN AS LONG AS THE TIDE ELEVATION IS BETWEEN THE BOTTOM OF IT AND THE MAXIMUM OPEN SETTINGS. 7. WHEN THE TIDE FALLS TO AN ELEVATION LOWER THAN THE BOTTOM OF THE SECONDARY FLAP AND THE WATER LEVEL BEHIND THE PRIMARY FLAP ARE EQUAL THERE WILL BE NO FLOW. 8. AT A POINT IN TIME THE WATER LEVEL BEHIND THE PRIMARY FLAP WILL RISE TO A LEVEL GREATER THAN THE TIDAL ELEVATION AND OUTFLOW WILL OCCUR AGAIN. THE COMPLETE CYCLE OR A PORTION OF IT MAY NOW REPEAT AGAIN. 9. MANUAL LOCK OPTION ON THE SECONDARY FLAP ALLOWS THE GATE TO FUNCTION AS A TRADITIONAL TIDE GATE WHEN FISH PASSAGE AND OR TIDE FLUSHING IS NOT REQUIRED.

AS THE TIDE CONTINUES TO RISE IT WILL LIFT THE CLOSURE FLOATS AND THEY WILL CLOSE AND LOCK THE SECONDARY FLAP, THEREBY STOPPING TIDAL INFLOW AND PROTECTING AGAINST STORM SURGES. 5. THE TIDE MAY NOW RISE TO A GREATER ELEVATION AND THERE WILL BE NO INFLOW AS BOTH FLAP GATES ARE CLOSED. 6. AS THE TIDE FALLS THE LATCH FLOATS CAN BE SET TO UNLOCK THE SECONDARY FLAP AT A PREDETERMINED ELEVATION, THEREBY CONTROLLING THE AMOUNT OF TIDAL INFLOW ALLOWED. ONCE THE LATCHING FLOATS UNLATCH THE SECONDARY FLAP IS ALLOWED TO OPEN AND WILL REMAIN OPEN AS LONG AS THE TIDE ELEVATION IS BETWEEN THE BOTTOM OF THE DOOR AND THE MAXIMUM OPEN SETTINGS. 7. WHEN THE TIDE FALLS TO AN ELEVATION LOWER THAN THE BOTTOM OF THE SECONDARY FLAP AND THE WATER LEVEL BEHIND THE PRIMARY FLAP ARE EQUAL THERE WILL BE NO FLOW. 8. AT A POINT IN TIME THE WATER LEVEL BEHIND THE PRIMARY FLAP WILL RISE TO A LEVEL GREATER THAN THE TIDAL ELEVATION AND OUTFLOW WILL OCCUR AGAIN. THE COMPLETE CYCLE OR A PORTION OF IT MAY NOW REPEAT AGAIN. 9. MANUAL LOCK OPTION ON THE SECONDARY DOOR ALLOWS THE GATE TO FUNCTION AS A TRADITIONAL TIDE GATE WHEN FISH PASSAGE AND OR TIDE FLUSHING IS NOT REQUIRED. THE CONSTRUCTION OF THE PRIMARY AND SECONDARY FLAPS AND MAIN HINGE ARMS ARE FABRICATED FROM ALUMINUM, WITH STAINLESS STEEL PINS RUNNING IN UHMWPE BUSHINGS. THE SECONDARY FLAP HAS AN INTEGRAL FLOAT CHAMBER THAT IS BOTH SIZE AND LOCATION ADJUSTABLE WHICH ALLOWS IT TO MAINTAIN A SLIGHTLY POSITIVE BUOYANCY. THE FULLY ADJUSTABLE CLOSURE FLOATS ARE ATTACHED WITH STAINLESS STEEL RODS AND HARDWARE. THE CLOSURE FLOATS ARE ADJUSTABLE IN SIZE AND LOCATION ALLOWING FINE TUNING OF THE OPENING / CLOSING EVENT OF THE SECONDARY FLAP. THE MOUNTING FRAME OR SPIGOT MAY BE EITHER ROUND OR SQUARE TO ACCOMMODATE A VARIETY OF MOUNTING CONFIGURATIONS. THE SECONDARY FLAP OR FLAPS MAY BE LOCATED ALMOST ANYWHERE ON THE PRIMARY FLAP TO ALLOW FOR THE CONTROL OF TIDAL WATER TO AN ESTUARY OR FISH PASSAGE. THE OPENING AND CLOSING EVENTS OF THE SECONDARY FLAP OR FLAPS CAN BE CUSTOMIZED TO ACCOMMODATE A VARIETY OF MOUNTING CONDITIONS.

SUMMARYTHE MODEL GH-37 TIDE REGULATED FLAP GATE OFFERS MANY ADVANTAGES OVER SIMILAR PRODUCTS IN USE TODAY: DRAINAGE CAPACITY IS NEVER RESTRICTED. MANUAL LOCK OF SECONDARY DOOR ALLOWS SEASONAL USE OF TIDE REGULATED FEATURE WITHOUT RESTRICTING DRAINAGE THRU THE MAIN FLAP GATE. CUSTOM SIZING OF THE SECONDARY DOOR ALLOWS CONTROL OF VOLUME OF UPSTREAM FLOW WITHOUT RESTRICTING DOWN STREAM FLOW. THE SECONDARY DOOR MAY BE OPENED ON BOTH RISING AND FALLING TIDES.

GOLDEN GATES MODEL GH-100, GH-105, STAINLESS STEEL SLUICE GATE, STAINLESS STEEL WEIR SLUICE GATE, AVAILABLE IN WALL, TIMBLE, IN CHANNEL MOUNTED.

GH-100OUR PREMIER IS THE GH-100 FULLY WEDGED STAINLESS STEEL SLUICE GATE. THIS GATE HAS BEEN IN THE FIELD SINCE 1988. THE MODEL GH-100 OFFERS SOME UNIQUE DESIGN FEATURES THAT HAVE PROVEN IT TO BE A RELIABLE AND COST EFFECTIVE ALTERNATIVE TO THE TRADITIONAL CAST IRON SLUICE GATE. WHILE THIS GATE IS FABRICATED AND NOT CAST IRON, IT SHOULD NOT BE CONFUSED WITH A FABRICATED SLIDE GATE. THE GH-100 SLUICE GATE APPURTENANCES MEET THE LATEST REQUIREMENTS OF AWWA C-501. DEPENDING ON THE WATER CONDITIONS THE SLUICE GATE FRAME AND DISC ARE FABRICATED FROM EITHER TYPE 304 OR TYPE 316 STAINLESS STEEL. ALTHOUGH THEY DO NOT MEET THE MATERIAL REQUIREMENTS FOR AWWA C-501, WHICH SPECIFIES CAST IRON, THE STRUCTURAL DESIGN IS IN CONFORMANCE WITH THE AMERICAN WATER WORKS ASSOCIATION FOR CAST IRON SLUICE GATES {ANSI/ AWWA C-501-92, AMERICAN INSTITUTE OF STEEL CONSTRUCTION SPECIFICATIONS ASD-NINTH EDITION UNIFORM BUILDING CODE U.B.C. 97}. THE MODEL GH-100 IS PROVIDED WITH ADJUSTABLE WEDGE BARS ON THE SIDES AND TOP OF THE GATE. AROUND THE U.S., OWNERS ARE TURNING AWAY FROM CAST IRON SLUICE GATES. TO KEEP FROM SEIZING, A CAST IRON SLUICE GATE HAS TO BE EXERCISED REGULARLY AND THIS CAN BE A NUISANCE TO OWNERS AND PLANT OPERATORS. THE GH-100 SLUICE GATE DOES NOT HAVE METAL-TO-METAL CONTACT, ELIMINATING THE NEED TO OPERATE THE GATE ON A REGULAR CYCLE. STAINLESS STEEL IS A SUPERIOR METAL AND CAN BE APPROXIMATELY 25% TO 35% LESS EXPENSIVE THAN CAST IRON. LIKE THE CAST IRON SLUICE GATE, OUR GH-100 UTILIZES A WEDGING SYSTEM TO MINIMIZE LEAKAGE. THREADED STEMS ARE SIZED IN ACCORDANCE WITH CALCULATED TENSILE AND COMPRESSIVE LOADS WHICH WILL BE ENCOUNTERED WHILE OPENING AND CLOSING THE GATE, AND STEM GUIDES ARE SPACED SO THAT BUCKLING OF THE STEM UNDER COMPRESSION DOES NOT OCCUR. COLD ROLLED THREADS ARE PROVIDED FOR LESS FRICTION AND LONGER SERVICE LIFE, ESPECIALLY IMPORTANT IN MODULATING APPLICATIONS.

GOLDEN GATES MODEL GH-40, GH-60 ALUMINUM SLIDE GATE & ALUMINUM WEIR GATE

SLIDE GATESGOLDEN HARVEST FABRICATED SLIDE GATES ARE THE INDUSTRY STANDARD FOR PRICE AND PERFORMANCE. UHMW BUSHINGS IN GUIDE GROOVES AND NEOPRENE FACE SEALS ON SOME MODELS, PROVIDE FOR LOW LEAKAGE SOLUTIONS AT MODEST HEAD LEVELS. THE COMPRESSION J- BULB DESIGN PROVIDES FOR A LOW LEAKAGE CLOSURE. GOLDEN HARVEST SLIDE GATES CAN BE PROVIDED IN ALUMINUM, STAINLESS STEEL, MILD STEEL, AND FRP DEPENDING UPON APPLICATION REQUIREMENTS. RISING OR NON-RISING STEMS; STANDARD OR FLUSH-BOTTOM SEATING; SPECIAL WEIR MODELS AVAILABLE. NOTCHED SLIDES ARE AVAILABLE FOR WEIR APPLICATIONS. MOUNTING OPTIONS INCLUDE: FLAT-BACK FOR FLUSH MOUNTING TO A WALL FACE, SPIGOT-BACK FOR USE IN NEW WALL CONSTRUCTION, AND FLANGE-BACK FOR MOUNTING TO EXISTING STRUCTURES. STANDARD LIFTS ARE HANDWHEEL OR ENCLOSED GEAR TYPES, AND CAN BE SUPPLEMENTED WITH ELECTRIC OR HYDRAULIC ACTUATORS. GOLDEN HARVEST STRONGLY RECOMMENDS USING RISING SPINDLES WHEREVER POSSIBLE, SINCE THE THREADED SECTION, AS WELL AS THE THRUST ARRANGEMENT, ARE AT THE TOP, OUT OF THE POTENTIALLY CLOGGING FLUID. UNLESS THEIR USE IS ESSENTIAL, NON-RISING STEMS SHOULD BE AVOIDED, TO PREVENT POSSIBLE CLOGGING OF THE THREADS. WHERE STEM COVERS ARE NECESSARY, CLEAR COVERS CAN BE PROVIDED FOR VISUAL POSITION INDICATION. THREADED STEMS ARE SIZED IN ACCORDANCE WITH CALCULATED TENSILE AND COMPRESSIVE LOADS WHICH WILL BE ENCOUNTERED WHILE OPENING AND CLOSING THE GATE, AND STEM GUIDES ARE SPACED SO THAT BUCKLING OF THE STEM UNDER COMPRESSION DOES NOT OCCUR. COLD ROLLED THREADS ARE PROVIDED FOR LESS FRICTION AND LONGER SERVICE LIFE, ESPECIALLY IMPORTANT IN MODULATING APPLICATIONS. FOR MANUAL OPERATION, HANDWHEEL DIAMETERS AND GEARBOX RATIOS ARE MATCHED TO STEM SIZES AND THREAD PITCHES, SO THAT THE TIME REQUIRED TO CYCLE THE GATE IS KEPT TO A MINIMUM, AT THE SAME TIME LIMITING HANDWHEEL RIM EFFORT TO NORMAL ACCEPTABLE LEVELS. CHANNEL GATES CAN HAVE A SEPARATE BOLT-ON HEADFRAME, ENABLING THE EMBEDDED FRAME TO BE INSTALLED IN THE SLOTS WITHOUT THE GATE, HEADFRAME, AND OPERATING GEAR, WHICH CAN BE FITTED LATER, AFTER CONSTRUCTION WORK HAS BEEN COMPLETED, REDUCING THE POSSIBILITY OF DAMAGE TO THE FULL ASSEMBLY.

WEIR GATESGOLDEN HARVEST GOLDEN GATES WEIR GATES ARE DESIGNED TO CONTROL UPSTREAM WATER ELEVATION AND CAN PROVIDE A ROUGH ESTIMATE OF FLOW USING NOTCHED GATES VIA THE DOWNWARD-OPENING DESIGN. WEIR GATES FUNCTION LIKE SLIDE GATES, EXCEPT THAT THE OUTFLOW TRAVELS OVER THE TOP OF THE GATE, AND THEY ARE USUALLY DOWNWARD OPENING. GOLDEN HARVEST PROVIDES NEOPRENE SEALS IN ADDITION TO UHMW BUSHINGS WHEN A LOW LEAKAGE INTERFACE IS REQUIRED. LIKE OTHER GOLDEN GATES, OUR WEIR DESIGNS CAN BE FABRICATED FROM STAINLESS STEEL, ALUMINUM, MILD STEEL, AND FRP.

COMBINATION GATESTHE COMBINATION GATE IS LIKE A NORMAL SLIDE OR SLUICE GATE WITH THE ADDITION OF A FLAP GATE MOUNTED ON THE SLIDE OR SLUICE GATE. IN THE SLIDE-CLOSED POSITION, IT ACTS AS AN AUTOMATIC FLAP OR TIDE GATE. IN THE SLIDE-OPEN POSITION, WATER CAN FLOW IN EITHER DIRECTION. THIS ALLOWS FOR ONE-WAY OVER-RIDE AND CAN BE USED TO PASS LARGER THAN NORMAL FLOWS AS WELL AS MANUAL FLUSHING OF TIDAL MARSHES TO PRESERVE NATURAL ECOSYSTEMS, SALINITY AND FISH PASSAGE.. WHEN USED WITH ELECTRIC ACTUATORS, LEVEL SENSORS, AND A CONTROL SYSTEM, THE COMBINATION GATE BECOMES THE BEST OF BOTH FOR FISH PASSAGE AND RESTORATION APPLICATIONS. WITH SIMPLE PROGRAMMING, THE SYSTEM CAN PROVIDE THE BEST PRESERVATION OF A RELATIVELY LARGE VOLUME OF POTENTIAL WATER STORAGE CAPACITY BEHIND THE DIKE SHOULD IT BE NEEDED FOR DETENTION OF UPLAND RUNOFF ASSOCIATED WITH A COASTAL STORM. IN THIS WAY THE COMBINATION GATE SIMULTANEOUSLY MAINTAINS FLOOD PROTECTION TO THE UPLAND AREA WHILE ALLOWING TIDAL FLUSHING OF THE LOW-LYING WETLANDS UNDER A USER-PROGRAMMABLE PLC. THE GOLDEN HARVEST FISH AND ENVIRONMENT-FRIENDLY GATES CAN ALSO BE FLAP GATES WITH ADDITIONAL FLOAT-CONTROLLED FLAPS, OR MOVEABLE SLIDES.
