PZ73TC ceramic knife gate valve

Product Overview:

New ceramics have much higher bonding strength than metals. In general, the crystal ion radius that makes up ceramic materials is small, and the ion valence is high, with a large coordination number. These properties determine that the tensile strength, compressive strength, elastic modulus, hardness, and other properties of ceramic materials are very high. However, the brittleness and difficulty in processing of ceramics themselves limit their application scope. In the past decade, due to the development and progress of martensitic transformation toughening technology, composite material science technology, and the concept of nano ceramics, the brittleness of ceramics has been greatly improved, and their toughness and strength have been greatly enhanced, expanding their application scope. Wear resistant ceramic knife type gate valves are suitable for use in pipelines with high hardness particles and other media, as well as soft particles but corrosive media for opening and closing purposes.

The sealing surface materials of the gate and valve seat are made of structural ceramics, which are wear-resistant, corrosion-resistant, and high-temperature resistant. The sealing surface uses hard sealing and the parts in contact with the medium are all made of structural ceramic materials, with extremely high chemical stability and hardness. Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and low thermal expansion.

Performance characteristics:

The sealing components and vulnerable overcurrent components of the engineering ceramic knife gate valve are made of toughened engineering ceramic materials; Capable of withstanding wear and erosion of particulate media in high-speed fluids, with a long service life for valves; The cost-effectiveness is 10 times higher than that of ordinary valves.

Main performance specifications:

1. Sealing surface material: two types of structural ceramics or superhard surface alloy materials.

2. Gas solid mixed media such as coal slag and ash are used, and structural ceramic materials are used to manufacture the gate, valve seat, and flow channel parts, which are wear-resistant and have a long service life.

3. Excellent sealing performance and can be repaired with sealing cotton.

4. The imported valve seat can be used as a scraper plate, which can close freely even in the event of dust falling.

5. The valve body cavity structure completely avoids the problems of jamming and dust accumulation.

6. Drive modes: manual, pneumatic, electric, etc.
