Knife gate valve is also called knife gate valve, knife gate valve, slurry valve and mud valve. Its opening and closing parts are rams. The moving direction of the rams is perpendicular to the fluid direction, and the media is cut off by blade-shaped rams that can cut fiber materials. The rams have two sealing surfaces. The wedge-shaped angle of the two sealing surfaces of the most commonly used mode gate valve varies with valve parameters, usually 50. The rams of wedge-shaped knife gate valves can be made into a whole, called rigid rams. It can also be made into a gate which can produce slight deformation, so as to improve its manufacturability and make up for the deviation of sealing surface angle in the processing process. This kind of gate is called elastic gate. In fact, there is no chamber in the valve body, and the gate moves up and down in the side guide groove, and is pressed against the valve seat by the lug at the bottom. If it is necessary to achieve higher medium tightness, the O-shaped sealing valve seat can be used to realize bidirectional sealing. Knife-gate valve has small installation space, low working pressure, difficult accumulation of sundries and low price.
Driving modes of knife gate valve
manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electric control hydraulic and pneumatic. Shape of knife gate valve: open stem and concealed stem. Material of knife gate valve: cast iron, cast steel, carbon steel, stainless steel, fluorine lining, etc. Seal of knife gate valve: hard seal, soft seal, single-side seal and double-side seal.
Installation and use instructions
1. Before the installation of knife gate valve, check the valve cavity and sealing surface, and there is no dirt or sand attached;
2. Bolts at all connecting parts shall be tightened evenly;
3. Check the packing parts for compaction, so as to ensure the tightness of the packing and the flexible opening of the shutter;
4. Before installing the valve, the user must proofread the valve model, connection size and pay attention to the flow direction of the medium to ensure consistency with the valve requirements;
5. When installing the valve, the user must reserve the necessary space for valve driving;
6. The wiring of the driving device shall be carried out according to the circuit diagram;
7. The knife gate valve must be maintained regularly, and it is not allowed to collide and squeeze at will, so as not to affect the seal
