Spiral gate is the main control equipment of a powder, crystal and grain material and small volume of material throughput, widely used in metallurgy, mining, building materials, food, chemical and other industries to control the rapid flow changes or cut off.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
Screw gate valve application
For adjusting the cement material intermediate positions within the flow, to close the middle bin outlet in the equipment maintenance, stop feeding.
Screw gate valve installation method
Inlet with fasteners and intermediate bin outlet flange is connected with the discharge port is connected with the inlet feeder fastening piece.

1, opening and closing fast: opening and closing time is only the traditional product of 1/6.
2, fast operation: screw, nut work in the powder material isolated from the sealed cylinder, to achieve a clean lubrication transmission, from dust. Influence of corrosion on the drive, to ensure that the valve operation is time-saving and labor-saving and lasting unabated.
3, closed strict: screw and cylinder tube at the junction of the use of a double layer of dust ring, so tight seal, do not fly dust, long life.
