Product Description
Stainless steel knife gate valve
Knife gate valve, also known as knife gate valve, knife gate valve, slurry valve, and mud valve, has a gate as its opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate that can cut fiber materials. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 5 °. The gate of the wedge type knife gate valve can be formed as a whole, It is called a rigid ram; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. The valve body actually does not have a cavity, and the gate rises and falls in the side guide groove, and is tightly pressed onto the valve seat by the bottom lug. If high medium sealing is required, an O-ring sealing valve seat can be selected to achieve bidirectional sealing. Knife gate valves have smaller installation space, low working pressure, and are less likely to accumulate debris, resulting in lower prices.
When a knife type gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, the sealing surface of the gate plate is pressed towards the other side of the valve seat by medium pressure to ensure the sealing of the sealing surface, which is self sealing. Most gate valves use forced sealing, that is, when the valve is closed, external force must be used to force the gate plate towards the valve seat to ensure the sealing of the sealing surface. This type of valve should generally be installed vertically in pipelines.
Knife gate valve driving methods: manual, chain wheel, electric, pneumatic, hydraulic, bevel gear, electric hydraulic, and pneumatic driving methods. Knife gate valve appearance: two types: open stem and non rising stem. Knife gate valve materials: cast iron, cast steel, carbon steel, stainless steel, fluorine lined, etc. Knife gate valve sealing: hard sealing, soft sealing, single sided sealing, double sided sealing, and other materials for sealing.
