Double-leaf O-type gate, Mining sector gate, Coal bin electro-hydraulic push rod O-type gate

2 Structural Features

Pleated gate[1] Composed of components such as the main body, sector gate plate, shaft, gears, seals, and actuator. Made from carbon steel welded construction, it features a unique structure, flexible operation, and reliable performance without jamming. Different transmission devices can meet various operational requirements. Electric gate valves are equipped with electric actuators featuring overload protection to prevent motor burnout, allowing for remote operation or programmable control; the reciprocating stroke can be adjusted and locked in position. Electro-hydraulic gate valves use electro-hydraulic actuators with full hydraulic transmission, enabling stepless speed adjustment for both pushing and pulling forces. Pneumatic gate valves utilize pneumatic actuators, which can be remotely controlled or locally operated through component assembly.

3 Working Principle

The bucket gate utilizes an electro-hydraulic actuator with full hydraulic transmission, allowing for infinite speed adjustment of both thrust and pull. The gate is operated manually or by an actuating mechanism that moves the lever, causing the gears to rotate the bucket plate around the axis, opening the two bucket plates to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuating mechanism drives the lever again to reset the bucket plate, closing the cutoff of the falling material.

4 Usage Instructions

Pleated gate[2] Please note the medium flow direction marked on the gate body during installation. When connecting the flanges, you must add sealing washers and then evenly tighten the bolts. Secondly, during operation, be clear about the opening and closing direction of the wing gate. Ensure the actuator is properly wired. It is crucial to regularly lubricate all传动 parts while in operation to extend the service life of the plate gate. Improper operation can increase the wear on the plate gate.

5 Uses

Bib GateSuitable for various bulk materials such as ores, coal, coke, slag, and chemical products with a bulk density of ≤2.5t/m³, widely used for bottom unloading in storage for industries such as construction materials, metallurgy, chemicals, and glass.
