Ceramic knife gate valves, also known as ceramic knife-shaped gate valves, ceramic abrasion-resistant knife gate valves, thin ceramic slag discharge valves, and thin ceramic slurry valves. The closure element is a gate plate, whose movement direction is perpendicular to the fluid direction, cutting the medium with a knife-shaped gate plate capable of slicing fibrous materials. The valve body of the ceramic knife gate valve actually has no chamber; the gate plate rises and falls in the lateral guide groove and is tightly pressed against the valve seat by the bottom lugs. For higher medium sealing, an O-shaped ceramic sealing valve seat can be chosen to achieve double-sealing. The ultra-short structural length saves materials and reduces the overall weight of the piping system; it occupies minimal effective space, effectively supporting the pipeline's strength, reducing pipeline vibration, and is suitable for installation at any angle on pipelines with different layouts. Specifically designed for solid-liquid two-phase flow medium pipelines, it features a structural form aimed at anti-throttling erosion, to satisfy the dual function of shutdown or shutdown + throttling for such medium pipelines.
