Knife type valve with a variety of seat options, and can be controlled according to site requirements, equipped with electric or pneumatic actuators, valve automation.
Two, structural characteristics:
PZ73H series Plum blossom type manual knife gate valve Is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.
There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge, the wedge angle varies with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of the deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.
Knife gate valve is closed, the sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the knife gate valve is sealed by force, that the valve is closed, to rely on external pressure to force the gate to the seat to ensure the sealing surface of the seal.
