Anti-Stuck Rotary Valve With Bayonet Type

In industrial production, dust characteristics vary vastly—from lightweight, adhesive food powders to high-temperature, highly corrosive chemical materials—posing significant challenges to the adaptability of dust collection systems and their components. Recently, ZZ Precision Engineering, specializing in specialty component manufacturing, emphasized that deeply customized rotary valves can effectively address these complex and diverse conditions.

Recently, a domestic manufacturer of dust collection equipment components announced the successful development of a new-generation rotary valve equipped with high-performance wear-resistant ceramic liners. This product addresses the industry challenge of traditional metal rotary valves experiencing rapid wear and short service life when handling highly abrasive dust, such as mineral powder and fly ash.

Rotary valves are specialized equipment used in powder conveying systems for unloading, metering, dust removal, quantitative conveying, mixing, and packaging. They are widely applied in various industries such as chemical, environmental protection, petroleum, metallurgy, refractory materials, power, cement, plastics, food, and pharmaceuticals. A common defect of conventional rotary sealing valves is that when a large amount of material enters the valve body, it can become blocked in the material chamber of the rotor, leading to the blockage of the entire rotary sealing valve and damaging a significant amount of material. Therefore, an anti-jamming structure is generally installed at the inlet of the rotary sealing valve. In the existing "anti-interference mechanism for rotary valve material conveying", two pairs of upper and lower feeding baffles are installed, which restrict and guide the material through them. However, when the rotor rotates, the material falls from the lower feeding baffle. If the baffle in the rotor chamber is just below the material at this time, the material will collide with the baffle, causing damage to the material. Additionally, for particles with high elasticity, the material may be ejected in various directions due to the collision. Therefore, it is necessary to design an anti-interference and anti-jamming rotary valve to solve the above technical problems.
