3kw Explosion-proof Motor Electric-Hydraulic Jaw Gate for Coal Storage Discharge and Loading Valve

Structural Features and Applications:Pleated gate series features simple structure, easy operation, and convenient discharging.  Long service life, flexible operation, utilizes   Welded from steel plate, driven by an electric (hydraulic) push rod for smooth operation and low failure rate, capable of quickly cutting off the material flow. Widely used in industries such as construction materials, metallurgy, mining, power, chemicals, light industry, and grain, it serves as the unloading control device for various drop-off systems.

（2) Temperature Range: ≤300°C

（3) Medium Flow Rate: ≤28 m/s

（4) Power Voltage: 380V 50Hz

（5) Adjustment Characteristics: Dual-position switch

（6) Electro-hydraulic Push Rod Models: DG Series Electric Push Rod or DYT Series Electro-hydraulic Push Rod

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

The gate is composed of the main body, a sector gate plate, shaft, gears, seals, and actuator, etc. It is made by welding carbon steel and features a structural design. Operation is flexible and reliable with no jamming issues. Different drive systems can meet various operational requirements. Electric sliding gates utilize electric actuators with overload protection to prevent motor burnout, allowing for remote operation or programmable control, with reciprocating travel that can be adjusted for position locking. Electro-hydraulic sliding gates use electro-hydraulic actuators with full hydraulic drive, enabling stepless speed adjustment for both pushing and pulling forces. Pneumatic sliding gates employ pneumatic actuators, which can be remotely operated or controlled on-site through component assembly.

Operating Principle

 The palate gate utilizes an electro-hydraulic push rod, featuring full hydraulic transmission with variable speed adjustment for both thrust and pull forces. The gate is operated manually or by an actuator, which moves the lever, causing the gears to rotate the sector gate around the axis. This opens the two sector gates to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuator drives the lever again to reset the sector gate, closing off the falling material.

Instructions for Use

Pleated gate valves: Firstly, when installing, please note the medium flow direction indicated on the valve body. When connecting the flanges, add sealing washers and then tighten the bolts evenly. Secondly, during operation, identify the switch direction of the butterfly plate and properly wire the actuator. Even during operation, that is.  Regularly apply lubricant to all transmission parts to extend the lifespan of the labial valve. Improper operation will increase the degree of wear on the labial valve.

Usage

 Lip gate valves 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.
