Product Description

Rotary valves are also called shut-off fans, unloaders, and air lock valves. They are divided into three categories: ordinary, pressure-resistant, and high-temperature resistant. Equipment for uniform and continuous batching, conveying and unloading. Pneumatic conveying engineering and bulk material handling systems in various fields such as powder engineering, grain processing, ports, chemicals, food, building materials, mining and other industries.

The rotary valve adopts an elastic impeller to enhance the flexible seal and eliminate the jamming of the impeller. The bearing seat is shifted to the outside of the valve body to isolate the direct source of dust particles, prolong the service life of the bearing and facilitate maintenance. According to the characteristics of the materials, uses and conditions of use, the rotary valve has a variety of structural types. The selection should be based on the characteristics of the conveyed materials, adhesion, temperature, humidity, etc.

According to the shape of the discharge device is divided into: round port discharge device, square port discharge device

The unloader is divided into ordinary type, pressure resistant type and temperature resistant type.The ordinary type is used for the material at room temperature below 80 degrees. It can feed the material to the feeding pipe continuously and evenly.The pressure resistant type adopts the closed rotor, which is widely used in the suction and delivery type, pressure delivery type airflow conveying system and negative pressure conveying equipment, so that the airflow pressure in the conveying pipe does not leak, and the material can be transported and settled safely.Temperature resistant type according to the material conveying and feeding mouth temperature rise is different because the temperature quality has an impact on the expansion of the body, adverse to the bearing and oil seal system.
