Coal unloader, Coal storage electro-hydraulic jaw gate, Jaw-type sludge material hopper valve

Section 1: Houshou Valve Operating Principle:

The鄂式valve is manually or mechanically actuated to move the lever, which drives the gears to rotate the sector gate around the axis, causing the two sector gates to open to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuator moves the lever to reset the sector gates, closing off the falling material. The jaw type gate valve is suitable for dry bulk materials with a specific gravity of 2.5t/m³, such as various ores, coal, coke, slag, and chemical products, and is widely used in industries like building materials, metallurgy, chemicals, and glass for bottom unloading of storage.

Usage

Electromagnetic hydraulic flap gate with power failure reset is widely used in construction materials, metallurgy, mining, power, chemical industry, etc., and serves as the unloading control device for various discharge systems.

Structural Features

Easy installation directly below the material storage. Powered by electro-hydraulic actuators, compact design for easier mounting. Smooth operation with low failure rate. Can quickly cut off the material flow. During power outages, the electro-hydraulic actuator can automatically reset and close the gate to prevent material spillage.

Operating Principle

With power failure resetElectro-hydraulic butterfly valveComposed of the main body, power-off and reset electro-hydraulic push rod, sector gate, shaft, gears, seals, actuator, and other components. The electro-hydraulic push rod operates to drive the sector gate to rotate around the shaft center, causing the two sector gates to open to the sides, allowing the material to fall. After the receiving device is fully loaded, the electro-hydraulic push rod then resets the sector gate, closing off the falling material.
