The stainless steel knife-shaped gate valve adopts a knife-type shutter and has good shearing effect. It is most suitable for fluids such as pulp, powder, fiber and other difficult to control, and is widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of valve seats to choose from, and with electric or pneumatic actuators for on-site control needs, the valve can be automated.
Precautions and features in use: Imported stainless steel "target=_blank> stainless steel knife-shaped gate valve is the shutter, the movement direction of the gate is perpendicular to the fluid direction, and the imported knife-shaped gate valve can only be fully open and fully closed. Can not be adjusted and throttled.
The gate has two sealing faces. The two sealing faces of the most commonly used mode gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife gate valve can be made into a whole, called The rigid ram can also be made into a ram that can produce a small amount of deformation to improve its processability and compensate for the deviation of the sealing surface angle during the machining process. This ram is called a resilient brake.
When the stainless steel "target=_blank> stainless steel knife gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is Self-sealing.
Most knife-type gate valves use forced sealing, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface.
Features of stainless steel "target=_blank> stainless steel knife gate valve:
1. The sealing effect is good, and the U-shaped gasket has good elasticity.
2, full-channel design, strong ability to pass.
3, the brake break effect is good, can effectively solve the leakage phenomenon after the blockage of the block, particle and fiber medium.
4, easy to maintain, you can replace the valve seal without removing the valve.
