stainless steel wafer knife gate valve
Description
Stainless steel knife gate valve adopts knife gate, with good shearing effect, most suitable for slurry, powder, fiber and other difficult to control the fluid, widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of seats to choose from, and can be equipped with electric or pneumatic actuators according to field control requirements, to achieve automatic valve operation.
Precautions in use and its characteristics: the opening and closing part of the imported stainless steel knife-shaped gate valve is the gate plate, the direction of motion of the gate plate is perpendicular to the direction of the fluid, the imported knife-shaped gate valve can only be fully opened and fully closed, can not be adjusted and throttled.
The gate has two sealing faces, the most commonly used mode of the gate valve two sealing faces form a wedge, the wedge Angle varies with the valve parameters, usually 50, the wedge knife gate valve can be made into a whole, called rigid gate; It can also be made to produce a micro deformation of the gate, in order to improve its processability, make up for the sealing surface Angle in the processing of the deviation, this gate is called elastic gate.
When the stainless steel knife gate valve is closed, the sealing surface can be sealed only according to the medium pressure, that is, according to the medium pressure, the sealing surface of the gate is pressed to the seat on the other side to ensure the sealing of the sealing surface, which is self-sealing.
Most knife gate valves are forced to seal, that is, when the valve is closed, it is necessary to forcibly press the gate to the seat according to the external force to ensure the tightness of the sealing surface.
Features of stainless steel knife gate valve:
1, the sealing effect is good, U-shaped gasket has good elasticity.
2, full path design, strong passing ability.
3, the brake breaking effect is good, can effectively solve the leakage phenomenon containing block, particle and fiber media after the brake breaking.
4, easy maintenance, no need to remove the valve can replace the valve seal.
