Rotary Valve
Rotary feeding valve is a special equipment used in powder (powder, granular material, powder-granule mixture) conveying system for unloading, metering, dust removal, quantitative conveying, mixing and packaging. It is widely used in chemical, environmental protection, petroleum, metallurgy, refractory materials, electricity, cement, plastics, food and medicine industries.
Product Overview
| Outlet size | DN100-DN400 |
| Discharge capacity | 1m3-5m3/h |
| Application fields | It is used in special equipment for unloading, measuring, dust removal, quantitative conveying, mixing, packaging and other industries in chemical industry, environmental protection, petroleum, metallurgy, refractory materials, electricity, cement, plastics, food and medicine. |
| Applicable materials | It is particularly suitable for conveying dry powder and small particle materials, such as cement, fly ash, grain, sand, titanium dioxide, aluminum powder, gypsum powder, rubber granules, wood chips, etc. |
Working principle:
The rotary feeding valve rotates an impeller with an equally divided structure in the housing through the transmission of the motor and reducer. The material from the upper silo or feeding device of the housing is filled into the cavity of the impeller, and the material rotates with the impeller. Remove from the lower part of the casing. The material can be discharged to the downstream evenly and continuously according to the requirements of the conveying system.
Based on the rotation of rotating parts such as rotating baffles, the valve changes from open position to closed position. This valve realizes the opening and closing action by the rotation of rotating parts, in which the plug body rotates with the valve stem to realize the switching function.
Product Advantages
-
Uniform and stable feeding, avoiding jamming.
The rotary feeder valve can discharge the material to the downstream evenly and continuously according to the requirements of the conveying system, ensuring the stability of the feeding. Because its design can avoid dust from squeezing into the bearing and jamming of large particles, the rotary feeder valve can operate stably under various working conditions.
-
Compact structure and easy installation.
The rotary feeder valve has a compact structure, which makes installation and maintenance relatively simple, and also facilitates the overall maintenance and maintenance of the equipment.
-
Wide range of applications.
With a pressure balancing device, it can be used in positive and negative pressure conveying systems and is widely used in environmental protection, metallurgy, chemical industry, grain, food and other industrial sectors.
-
High processing precision and good wear resistance.
The wear-resistant high-feed valve has a lining inside, which improves the wear resistance of the equipment and makes the equipment more durable. It can be made of cast iron, cast steel, stainless steel, titanium steel and other materials, and the flange mouth can be in various structural forms such as square or round to meet the different needs of users.
