With the overall structure, bevel gear knife gate valve includes body, disc and U-seal, groove and flexible U-seal at the bottom of the cavity. Disc is moved down when valve is closed, the bottom edge of disc meets with the seal and then compresses into the groove to achieve sealing. Disc is moved up when knife gate valve is opened, the bottom edge of disc breaks from seal. Seal bounces up with groove formation to prevent media accumulated in the body cavity, not blocked easily and residue, pipe is cleaned easily, and to prevent leakage when knife gate valve is closed .That improves knife gate valve's sealing effect effectively. With longer service life, simply maintenance ,flange O-ring sealing , without changing flange gasket, simply installation and small  friction coefficient ,flexibly opening and closing, the series knife gate valve can be equipped with manual ,electric, pneumatic, electric , bevel gear, etc. Actuator meets different industrial and mining using.
