Knife gate valve related knowledge

Knife-type gate valve due to the use of knife gate, has a good shear effect, the most suitable slurry, powder, fiber and other difficult to control the fluid, are widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of valve seat to choose from, and can be based on site control needs, equipped with electric or pneumatic actuators to achieve the valve automation. Material: cast iron, carbon steel, stainless steel Size range: DN50 ~ DN600 Maximum pressure: 1.0MPa. Knife gate valve products in use matters needing attention and its characteristics: Knife gate valve opening and closing pieces is the gate, the gate direction of movement and fluid direction perpendicular to the knife gate valve can only be fully open and fully closed, can not be adjusted and Throttle. The gate has two sealing surfaces. The two most commonly used gate valves are wedge-shaped. The wedge angle varies with the valve parameters, typically 50, and the gate of the wedge gate valve can be made in one piece and called Rigid gate; can also be made to produce a small amount of deformation of the gate, to improve its technology to make up for sealing surface angle in the process of deviation, this gate is called elastic gate knife gate valve closed, the sealing surface Can rely only on the media pressure to seal, that is, rely on the media pressure to the pressure on the other side of the valve seat seal to ensure that the sealing surface sealing, which is self-sealing. Most knife gate valve in the pipeline should be generally horizontal installation. Is the use of mandatory seal, that is, when the valve is closed, it must rely on external force to force the gate to the valve seat to ensure the sealing surface of the seal.
