• Long idle stable sealing property avoids frequent maintenance even after long-term storage for seasonal intermittent river regulation project

Step-by-step Installation & Operation Guide

1. Step1 Finish river channel foundation construction, pre-embed fixed steel plate on channel wall for welding stainless steel gate groove frame per river engineering drawing
2. Step2 Install channel-shaped stainless steel gate groove, ensure vertical flatness of the whole mounting base for slat sliding fit
3. Step3 Assemble stop log panel piece by piece from bottom to top via convex-concave rabbet interlock, embed rubber sealing strip inside each rabbet slot beforehand
4. Step4 Select handle or automatic grab hook lifting tool matching Stainless steel water regulating gate pull ring structure on each slat
5. Step5 Complete 0.1MPa forward hydraulic tightness test; add/remove slats to adjust gate height and verify cutoff & circulation function of Flow regulating penstock gate

Application Scenarios

• Small branch river seasonal water diversion regulation: Standard spliced Water flow control sluice gate stop log for farmland irrigation water interception adjustment
• Sewage-containing polluted river channel: Full 304 stainless steel Stainless steel water regulating gate variant for anti-corrosion long-term river cutoff
• Cost-controlled rural clean water river project: Economical cast iron frame option equivalent to Cast iron flow control sluice
• Large main river flood control auxiliary channel: Oversize customized Hydraulic operated flow control sluice gate stop log for emergency flood blocking adjustment
• Landscape river intermittent water storage control: Compact Flow regulating penstock gate spliced stop log for daily landscape water level fine-tuning

Benefits for Global Purchasers

• Lower construction cost: Split spliced structure eliminates large-scale integral gate hoisting foundation work, saving river channel civil engineering expense
• Flexible budget allocation: Aluminum/all stainless steel/cast iron frame three options match varied river regulation project investment grade
• Maintenance saving: Interchangeable single slat only needs partial replacement when damaged, no whole gate scrap loss of Stainless steel water regulating gate
• Storage space optimization: Disassembled slats can be stacked compactly to cut off-season spare parts warehouse occupation cost
• Unified core slat specification across full 500~4000mm size reduces spare parts stocking pressure for global river conservancy distributors

Certifications and Compliance

The spliced stop log gate series passes ISO9001 international quality management certification; all aluminum alloy and stainless steel raw material comply with international water conservancy equipment metal inspection specification, matching CE mechanical standard for cross-border export clearance.

Customization Options

• Size Customization: Non-standard special width between 500~4000mm customizable per buyer’s river channel construction drawing
• Material Customization: Swap gate leaf between aluminum alloy /304 stainless steel; replace standard stainless steel frame with anti-corrosion cast iron matching Cast iron flow control sluice cost standard
• Structure Customization: Adjust single slat height and rabbet dimension for special river silt-adhesion working condition
• Lifting Customization: Free switch between manual handle and automatic grab hook lifting mode
• Drive Customization: Add hydraulic lifting rack to convert manual stop log into full Hydraulic operated flow control sluice gate

Production Process & Quality Control

1. Step1 Raw material incoming inspection: Test mechanical property and anti-corrosion performance of aluminum alloy and 304 stainless steel before blanking cutting
2. Step2 Precision forming & rabbet processing: Complete single slat stamping, convex-concave rabbet CNC machining and pull ring welding; stainless steel channel frame bending forming
3. Step3 Accessory assembly: Embed rubber water stop strip into each slat rabbet slot, install compression spring inside gate groove for auxiliary sealing
4. Step4 Finished product tightness test: Each assembled stop log undergoes 0.1MPa forward hydraulic leakage test and repeated assemble/disassemble fatigue inspection
