Solid ceramic knife gate valve

Solid ceramic knife gate valveDesigned with a chambered valve body as the core, the gate adopts a blade shaped structure, which vertically lifts and lowers in the side guide groove, and achieves sealing by pressing the valve seat tightly with the bottom protruding ear. Its key components, such as gate plates, valve seats, and channel liners, are covered with toughened engineering ceramic materials to form a fully lined hard sealing surface. This valve supports multiple driving modes such as manual, pneumatic, and electric, and is suitable for scenarios that require remote automation control. The solid valve body structure can avoid perforation of the valve body caused by high-speed flushing of the medium, and the knife shaped gate can cut fiber or granular media to prevent scaling and blockage.

Solid ceramic knife gate valveApplication field

Mining and steel industry: Processing high wear media such as coal, slurry, and filter residue slurry to resist particle erosion and chemical corrosion.

Electric power industry: used for conveying ash slurry and power plant ash removal systems, capable of withstanding high-temperature particle wear and erosion.

In the field of chemical and petrochemical engineering: control acidic and alkaline solutions, corrosive gases and other media to prevent leaks caused by chemical corrosion.

Environmental engineering: Treatment of wastewater, mud, pollutants, and clarified water with suspended solids in purification devices to ensure stable system operation.

Paper and textile industry: Convey any concentration of pulp, material water mixture, cut fiber media, and avoid clogging.

Municipal sewage treatment: Treating complex media such as sewage and sludge to reduce maintenance frequency and costs.

Precautions for use

Pre installation inspection: Ensure that there is no dirt in the valve chamber and the sealing surface is clean and undamaged; Check the valve model, connection size, and medium flow direction to avoid sealing failure caused by backflow.

Operating standards: Avoid frequent and rapid opening and closing, reduce wear on the gate and sealing surface; Observe the valve status during opening and closing, and immediately stop the machine for inspection if any abnormalities are found.

Environmental protection: Keep the environment around the valve clean to prevent corrosion from corrosive media; Avoid thermal shock and prevent ceramic materials from cracking.

Regular maintenance: Regularly check the wear of sealing components and replace aging parts in a timely manner; Regularly lubricate moving parts such as valve stems and guide grooves to reduce friction.

Safety protection: Install warning signs near the valve to remind personnel to pay attention to high temperature or high pressure risks; Wear protective equipment during operation to prevent medium splashing.

Avoid collision: prevent the valve from colliding with hard objects, and avoid damage to the blade or valve surface.
