Knife gate valve, also known as knife gate valve, knife gate valve, slurry valve, slurry valve, its opening and closing member is the gate, gate movement direction is perpendicular to the direction of the fluid, relying on the knife-edge shaped gate that can cut fiber materials to cut off the medium. Knife gate valve generally does not exist in the chamber, the gate in the side guide groove lift, and by the bottom of the lugs pressed on the valve seat. Knife gate valve has a small installation space, low working pressure, not easy to accumulate debris, high economy.
1, knife gate valve drive: manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electronically controlled hydraulic and pneumatic-hydraulic drive.
2、Knife gate valve seal: hard seal, soft seal, single-sided seal, double-sided seal and other materials seal:
3, knife gate valve has a small installation space, low working pressure, not easy to accumulate debris, high economy.
4, the sealing surface can be surfaced with cobalt-based cemented carbide, wear-resistant, corrosion-resistant, anti-scratch performance is good. Soft seal can have good sealing performance, can reach zero leakage.
The use range of knife gate valve is:
1. Mining, coal washing, iron and steel industry - for coal washing pipeline, filter slurry pipeline, etc., ash discharge pipeline;
2. Purification devices - for wastewater, slurry, dirt and clarified water with suspended matter;
3. Paper industry - for any concentration of pulp, material-water mixture;
4. Power station ash removal - for ash slurry .
