What valve to use for mud?
What valve for mud?
When the over medium is slurry, wesdom focus on recommending the use of knife gate valve.
But some of our previous customers basically use butterfly valves, and if you need to replace them, it is recommended to replace the butterfly valves with flat gate valves or knife gate valves.
So why don't we recommend butterfly valve for over mud pipeline?
In principle, butterfly valves are not recommended for pipelines with mud. Whether soft-sealed or hard-sealed, the sealing cover of the valve will be damaged by the mud medium over time, leading to a decrease in the service life of the valve.
This problem can be avoided by using knife gate valves, which have a knife-like mud cutting effect on the edge of the disc. Material can choose carbon steel, ductile iron, gray cast iron, sealing surface available PTFE or carbide seal.
Introduction of knife gate valve:
Knife gate valve, also known as knife gate valve, knife gate valve, slurry valve, mud valve, its opening and closing member is the gate, the direction of movement of the gate is perpendicular to the direction of the fluid, by the knife edge-shaped gate that can cut fiber material to cut off the medium, the gate has two sealing surfaces, the most commonly used mode gate valve of the two sealing surfaces form a wedge, wedge angle varies with the parameters of the valve, usually 5 °, wedge-type knife gate valve gate can be made into a The gate of wedge-type knife gate can be made into a whole, called rigid gate; can also be made into a gate that can produce a small amount of deformation to improve its process, to make up for the deviation of the sealing surface angle in the process, this gate is called a resilient gate.
The valve body actually does not exist in the chamber, the gate in the side guide groove to lift, and by the bottom of the lug pressed on the seat, if you need to achieve a high media sealing, O-seal seat can be used to achieve a two-way seal.
Knife gate valve has a smaller installation space, low working pressure, not easy to accumulate debris, and lower price.
Knife gate valve principle:
Knife gate valve closed, the sealing surface can only rely on media pressure to seal, that is, rely on media pressure will be the sealing surface of the gate to the other side of the seat to ensure the sealing surface of the seal, which is self-sealing, most of the gate valve is used to force sealing, that is, when the valve is closed, to rely on external force to force the gate to the seat, to ensure the sealing surface of the seal. Knife gate valve in the pipeline should generally be installed vertically.
Knife gate valve drive mode:
Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electric-hydraulic and pneumatic-hydraulic drive mode.
Knife gate valve shape:
Open stem, concealed stem two kinds. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine lining, etc.
Knife gate valve sealing:
Hard seal, soft seal, single-sided seal, double-sided seal and other materials seal.
Knife gate valve features:
Ultra-thin knife gate valve with its small size, small resistance, light weight, easy to install, easy to disassemble and other advantages completely solve the common gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve and other types of valves with large resistance, weight, difficult to install, large footprint and other difficult problems.
Knife gate valve appeared, a large number of general cut-off class valves and regulating valves have been replaced.
Knife gate valves are used in the following areas:
1. mining, washing coal, steel industry - for washing coal 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 .
