Roller Gate is a type of gate used to control the flow of water in large waterway openings, with a design focus on economy and ease of operation. Here are some key information about Roller Gate:
Design features: The Roller Gate is composed of cast steel sliders, cast iron rollers, and rubber seals. The gate blades are box shaped with welded construction. This type of gate can be customized with different widths and heights according to the size of the waterway opening.
Type: Roller Gate is divided into two types: Overflow Type and Breastwall Type. Overflow type is usually designed with a water depth of 1 foot at the top of the gate, while breast wall type is suitable for situations where the water depth is deeper than the gate height.
Application areas: Roller Gate is widely used in power plant cooling water systems, municipal water management, flood control engineering, municipal sewage treatment plants, industrial water control projects, irrigation systems, and dam tops to increase reservoir capacity.
Operation method: Roller Gate is usually operated through threaded rods and manual or electric lifting devices. For gates with a width not exceeding twice the height, use a single rod for operation; For gates with a width much greater than their height, series rods are used.
Materials and Corrosion Protection: Although Roller Gates are typically made of carbon steel coated with epoxy paint, they can also be partially or entirely made of stainless steel to resist corrosive environments.
Size range: Due to the fact that Roller Gates are made of steel and have rubber seals in contact with the embedded concrete at an angle, they are very flexible in size range and can be manufactured into almost any size and configuration as needed.
Sealing and Contact Surface: The top and side seals are hollow J-shaped, while the bottom (threshold) seal is a heavy-duty flat seal that contacts the edge of the threshold.
