 Pleated gates, also known as pleated valves, jaw valves, discharge gates, electro-hydraulic pleated gates, electric pleated gates, arc valves, and pleated ash discharge gates, etc.

Pleated gate consists of components such as the main body, sector gate plate, shaft, gears, seals, and actuator. It is made by welding carbon steel and features a structural design. Operation is flexible and reliable with no jamming. Different drive units can meet various working conditions. Electric gate valves are equipped with electric actuators featuring overload protection to prevent motor burnout. They can be remotely operated or programmed, and the reciprocating stroke can be adjusted for position locking. Electro-hydraulic gate valves use electro-hydraulic actuators with full hydraulic transmission, allowing for infinite speed adjustment of both pushing and pulling forces. Pneumatic gate valves utilize pneumatic actuators, which can be remotely operated or locally controlled through component assembly.

Working Principle

 The palate gate utilizes an electro-hydraulic push rod, featuring full hydraulic transmission with variable speed adjustment for both pushing and pulling forces. The gate is manually or mechanically operated by a lever, which drives the gear to rotate the sector gate around the axis, allowing the two sector gates to open to the sides, causing the material to fall. Once the receiving device is fully loaded, the mechanism drives the lever again to reset the sector gate, closing off the falling material.

Usage Instructions

Pulley gate: First, upon installation, please note the medium flow direction marked on the gate body. When connecting the flanges, add a sealing gasket and then evenly tighten the bolts. Secondly, during operation, identify the opening and closing direction of the sector gate plate, and properly wire the actuator. This applies even during operation.  Regularly apply lubricant to all transmission parts to extend the lifespan of the labial valve. Improper operation will increase the wear on the labial valve.

Application

 Lip gates are suitable for bulk density≤2.5t/m³ various ores, coal, coke, slag, chemical products, and other loose materials, widely used for bottom unloading in storage for construction materials, metallurgy, chemicals, glass, and other industries.
