Introduction of Fan Gates

The fan gate is composed of a body, sector gate, shaft, seal, actuator， and other components; Push the rocker manually or by the actuator to make the fan-shaped ram rotate and open along the axis, and the material will fall immediately; After the receiving device is fully loaded, push the rocker to reset the sector ram and close and cut off the falling material. The structure of the fan gate is simple and welded by a high-quality steel plate, which has the characteristics of flexible opening and no jamming.

Brief introduction of fan gates

The fan gate is a common gate type in the headwater conveyance system. A sector door is a triangular door with an arc-shaped panel with two pages rotating vertically in the horizontal plane. The two-door leaves contact on the longitudinal axis of the lock to block the water flow, and each door turns into the gate warehouse in its own locker room to ensure access to the lock.

The sector gate is widely used in building materials, metallurgy, mining, laboratory, electric power, and other industries and is the discharge control device of various blanking systems.

Definition of gates

The gate refers to the equipment set on the water outlet of hydraulic structures to control the water flow. It has the function of opening and closing operations and regulating flow in moving water or still water, and provides maintenance conditions for its upstream or downstream. The gate is mainly composed of movable parts, embedded parts, and hoisting machinery. The movable part is generally composed of a panel and beam system, which is called a gate leaf structure. The embedded part is the component embedded around the gate orifice. Among them, the lintel, bottom sill, water stop seat plate, and other components form a water stop surface around the orifice that matches with the water stop device on the gate leaf structure. With the help of water pressure, the gate leaf structure is pressed on this water stop surface to achieve the purpose of water stop of the gate. The water stop device of the gate is an important part to ensure the reliable operation of the gate, especially for the high-head gate.

The water stop device set on the upstream face of the gate leaf is called the upstream water stop, and the water stop set on the downstream face is called the downstream water stop. The embedded supporting track and other components transmit the load borne by the gate leaf structure to the hydraulic structure.

According to the shape and structural characteristics of the gate retaining surface, there are plane gates, radial gates, sector gates, cylindrical gates, and miter gates.

Introduction of folding fan gates

The up-opening fan gate skip has the characteristics of a simple structure, large effective volume, tight gate locking, not exceeding the skip section when opening, and short unloading time. It has gradually occupied a leading position in the main shaft lifting container of China's coal mines.

The structure of the fan gate is simple and welded by a high-quality steel plate, which has the characteristics of flexible opening and no jamming.
