Hidden stem knife gate valve

Hidden stem knife gate valve (also known as knife gate valve), the opening and closing component of knife gate valve is the gate plate, and the movement direction of the gate plate is perpendicular to the fluid direction. Manual knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled

Knife gate valve, also known as knife gate valve, knife gate valve or knife slurry valve. Its opening and closing component is a gate, whose movement direction is perpendicular to the fluid direction. 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 commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge blade gate valve can be made into a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation, with practical effects as the main focus. Its processability compensates 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 chamber, and the gate plate rises and falls in the side guide groove, and is tightly pressed against the valve seat by the bottom protrusion. If high medium sealing performance is required, an O-shaped sealing valve seat can be used to achieve bidirectional sealing. Knife gate valve has a small installation space, low working pressure, and is not easy to accumulate debris. It is suitable for medium pipelines such as slurry, sewage, coal slurry, ash residue, and slag water mixture, and can be used for medium cutting and throttling
