Knife gate valve opening and closing member is a gate, the direction of movement of the fluid in the direction perpendicular to the gate, knife gate valve can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the sealing surface two most common mode of gate valve forming wedge, the wedge angle with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called rigid gate; when to be made to produce small quantities of deformation gate in order to improve its process, make up the sealing surface angle deviations arising during processing, this gate is called the flexible gate knife gate valve is closed, the sealing surface We can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the sealing surface of the seal, which is self-sealing. Most knife gate valve is sealed by force, that the valve is closed, the shutter will be forced to rely on external pressure to the seat, to ensure the sealing surface of the seal.
