Many people still don't know the stainless steel knife gate valve, and don't know what this gate valve is used for. Today, the editor will take you to understand the performance characteristics of the stainless steel knife gate valve. The stainless steel knife gate valve adopts a knife-shaped gate. It has a good shearing effect, and is especially suitable for the use of difficult-to-control fluids such as pulp, powder, and fiber. It is widely used in papermaking, petrochemical, mining, drainage, food and other industries.

Stainless Steel Knife Gate Valve

Matters needing attention and its characteristics in use: the opening and closing part of the imported stainless steel knife gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The imported knife gate valve can only be fully opened and fully closed, and cannot be adjusted or adjusted. flow.
The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge type knife gate valve can be made into a whole, called Rigid gate; it can also be made into a gate that can produce slight deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic gate.
When the stainless steel knife gate valve is closed, the sealing surface can only be sealed according to the medium pressure, that is, according to the medium pressure, the sealing surface of the gate is pressed to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing.
Most knife gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
Features of stainless steel knife gate valve:
1. Good sealing effect, U-shaped gasket has good elasticity.
2. Full diameter design, strong passing ability.
3. The gate breaking effect is good, and it can effectively solve the leakage phenomenon after gate breaking of media containing lumps, particles and fibers.
4. The maintenance is convenient, and the valve seal can be replaced without removing the valve.
The above is an introduction to the characteristics of stainless steel knife gate valve, do you understand!
