Product Details
Description:

A, product introduction:
PZ73H series Stainless steel knife type valve Due to the use of knife type gate has a good shearing, the most suitable fluid in the slurry, powder granules, fibers and other difficult to control, widely used in papermaking, petrochemical, mining, drainage, food and other industries. 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.
Second, working principle:
PZ73H series Stainless steel knife type valve As a kind of gate valve, gate valve working principle with some similar, are on the gate of the lift to complete the opening and closing of the valve. Ram direction of motion perpendicular to the direction of the fluid, by the blade shaped gate can cutting fiber material to cut off the media. The PZ73H series stainless steel knife type gate valve does not actually exist in the chamber, the gate side of the guide groove and the lifting lug bottom pressed on the seat, to achieve high medium sealing, can choose O shaped sealing seat bi-directional seal.
Three, structural characteristics:
1, PZ73H series Stainless steel knife type 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.
2, 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; gate can be made to produce micro deformation, to improve in the process, make up the sealing surface angle deviations arising during processing, the gate is called the flexible gate.
3, 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.
