Introduction and characteristics of the pneumatic transmission type knife gate valve:
The pneumatic transmission type knife gate valve is also called the flashboard valve, it is a kind of valve disc always closely contact with the valve seat. Its principle: Opening a round mouth on the flashboard. The pneumatic transmission type knife gate valve through the gate opening and closing the circular disc are completely out of the mouth with sizes do and consistent action. The advantages of this valve is that the body path has no grooves, and the medium won't be jammed and all-pass runoff flux characteristics, suitable for the pipe which is used in powder particles. The sealing structure can be divided into soft seal and hard seal structure. Penetration type knife gate valve has a sophisticated structure, good in usability and compact structure such characteristics.The sealing seat is designed for the structure with anti-wear and automatic compensation function, so it has longer life. In the process of closing and opening, the seat with ram has been close to the movement, the valve opening and closing force is stable, and has the characteristics of cutting medium.
