Working Principle
The rotary valve (air lock valve) is driven by a motor to rotate its rotor, and the blades on the rotor form multiple independent sealed chambers with the housing. When materials enter the chambers from the upper hopper, they are carried to the lower outlet by the rotating rotor and discharged. During the conveying process, the precise fit between the rotor and the housing can effectively isolate the air pressure between the upper and lower parts. This not only ensures the continuous falling of materials but also prevents the reverse flow of air, thus realizing the dual functions of air sealing and material feeding. Its working process does not require additional seals, and a dynamic seal is formed by the mechanical structure itself, making it suitable for the conveying of powder and granular materials under positive or negative pressure conditions.
Product Features
The rotary valve has a compact structure, which is easy to install and maintain, and can adapt to different pipe diameters and working condition requirements. The blade design can be optimized according to the material characteristics: for example, wear-resistant materials are used for hard particles, and flexible blades are suitable for viscous materials to avoid blockage or wear. It operates stably with low noise and can be seamlessly connected with equipment such as conveying pipelines and silos, widely used in grain processing, chemical industry, environmental protection and other fields. With the dual functions of conveying and sealing, it is a key equipment for connecting high and low pressure environments, which can effectively improve the efficiency and safety of the pneumatic conveying system.

Frequently Asked Questions (FAQ)
What are the main capacity differences between the XZF-5 and XZF-11 models?
The XZF-5 model has a volume capacity of 5 liters per revolution with a power range of 0.5/0.75 kw. The larger XZF-11 model offers a capacity of 11 liters per revolution with a power range of 0.75/1.1 kw. Both models run at rotate speeds of 24/35 rpm.
How does the rotary valve prevent air leakage during material feeding?
The valve achieves air sealing through the precise mechanical fit between its rotating rotor blades and the outer housing. This design forms multiple independent sealed chambers that allow materials to pass through while preventing air from flowing in the reverse direction.
What material options are available for these rotary valves?
The rotary valves are manufactured using high-quality stainless steel or carbon steel, making them suitable for various industrial applications and material handling conditions.
Can the rotor blades be customized for specific types of materials?
Yes, the blade design can be optimized based on material characteristics. Wear-resistant materials are used for handling hard particles, while flexible blades can be integrated for viscous materials to prevent build-up and blockage.
