Gate Cut The Role And Advantages In The Industry

Ningbo Fenfa Valve Co.,Ltd | Updated: May 15, 2017

Knife gate valve has a good shear effect and the advantages of the industry you understand?

Pneumatic knife type gate valve is the opening and closing parts of the gate, the direction of movement of the gate and the fluid direction perpendicular to the manual knife gate valve can only be fully open and fully closed, can not be adjusted and throttling. There are two sealing surfaces on the gate. The two sealing surfaces of the most commonly used gate valve are wedge-shaped, and the wedge angle varies with the valve parameters. Typically, the wedge-type gate valve can be made as a whole Rigid gate.

The knife gate is widely used in papermaking, petrochemical, mining, drainage, food and other industries. It is suitable for pulp, powder, fiber and other difficult to control fluid. With a variety of seat to choose from, and can be based on site control needs, equipped with electric or pneumatic actuators, to achieve the valve automation.

Knife gate valve in the industry advantage

Knife gate valve in the industry have a certain price advantage and technological advantages. There are two sealing surfaces on the gate. The two sealing surfaces of the most commonly used gate valve are wedge-shaped, and the wedge angle varies with the valve parameters. Typically, the wedge-type gate valve can be made as a whole Rigid gate; can also be made to produce trace deformation of the gate, in order to improve its craft, to make up the sealing surface angle in the processing process of the deviation.

Typically, the wedge-type gate valve can be made as a whole Rigid gate; can also be made to produce trace deformation of the gate to improve its craft to make up the sealing surface angle in the processing of the deviation generated, this gate is called the elastic gate knife gate valve closed, the sealing surface Can only rely on the media pressure to seal, that is, relying on the media pressure to the gate of the sealing surface pressure to the other side of the valve seat to ensure that the sealing surface of the seal, which is self-sealing. Most of the ceramic knife gate valve is forced to seal, that is, when the valve is closed, it is necessary to rely on external force forced to the valve seat to ensure that the sealing surface sealing.
