Many typical features of knife gate valve

Knife gate valve has the advantages of simple and compact structure, reasonable design, light-weight material, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, easy installation and easy disassembly, etc., completely solving the ordinary gate

Valves, flat gate valves, globe valves, regulating valves, butterfly valves, ball valves and other valves have heavy weight, large flow resistance, large area, and difficult installation. They can replace general cut-off valves and regulating valves, and can work at 1.0MPa-2.5 MPa

, Working normally under the temperature of -29-550 ℃. The gate of the knife gate valve has a shearing function, which can scrape off the adhesion on the sealing surface and automatically remove debris. The stainless steel gate can prevent seal leakage caused by corrosion.

Knife gate valve is suitable for oil, water and steam pipelines of coal preparation, slag discharge, urban sewage treatment, food, papermaking, medicine, petroleum, chemical industry, etc. of mine power plants, to connect or cut off cement slurry and gold mine in pipelines Powder, mineral sand,

Slag, coal slime, pulp, wood pulp, tailings, fiber, dust, chemical treatment sewage, sedimentation tank, asphalt, silo export, fruit, grain, slaughterhouse wastewater and other media.

1. The liftable sealing surface of the gate can scrape off the adhesion on the sealing surface and automatically remove debris.
2. The stainless steel gate can prevent seal leakage caused by corrosion, and fine grinding and polishing treatment can obtain better sealing effect. The bottom end of the blade is processed into a blade shape, which has the function of cutting off soft materials such as fiber, paper pulp and wood pulp, and has good opening and closing functions.
3. The stainless steel valve body is durable, the design of the valve body ribs improves the strength of the valve body, and the double-headed screw is used to open and close more quickly.
4. The overall stainless steel material can prevent corrosion damage. The valve body and packing culvert are all precision casting. The valve body is made of flange-type integral casting. The material can be selected according to user needs. Wear-resistant and non-sticky.
5. The all-round DC channel design is free of slag and jamming.
6. Scientific upper seal packing design makes the upper seal safe and effective and durable.
7. Short structure length, can save raw materials, installation space, and also effectively support the strength of the pipeline.
8. The guide block on the body of the knife gate valve allows the gate to move correctly. The extrusion block ensures the effective sealing of the gate.
9. Knife gate valve can also choose any drive mechanism.
10. V-shaped gate can be used as a regulating valve.
11. Compact design, small space occupation, light weight, cheap price, easy installation, perfect anti-wear and anti-blocking measures, easy maintenance, convenient use and long life, and optional drive device.
12. The valve plate has multiple support points, making the valve plate self-centering. When the valve is closed and back pressure is applied, the valve plate does not shift.
