A Flanged Rotary Airlock Valve is a precision industrial component designed for airtight isolation and continuous quantitative feeding/discharging of bulk solid materials,characterized by its flanged connection design that enables quick,secure installation with pipelines,silos,or dust collectors.It is widely used in pneumatic conveying systems,dust removal equipment,and material storage systems,serving as a critical barrier to maintain pressure balance and prevent air backflow or dust leakage.

The key structure of the flanged rotary airlock valve includes a sealed casing,a star-shaped rotor with 6–12 blades,a drive unit(motor+reducer),high-performance sealing components,and standard flanges(ANSI,DIN,or GB standard)at the inlet and outlet.The flanges are made of high-quality carbon steel or stainless steel,ensuring strong connection tightness and compatibility with various industrial pipelines.The casing and rotor are also available in carbon steel or stainless steel 304/316 to meet different working environment requirements.

Its working principle is efficient and reliable:materials from the upper hopper or silo fall into the rotor blade cavities by gravity.The drive unit drives the rotor to rotate at a constant speed,and the blades carry the materials downward to the bottom outlet for discharge.The minimal clearance between the rotor and casing forms a tight air seal,isolating positive/negative pressure zones.The flanged connection ensures no air leakage at the joint,further enhancing the airtight performance of the entire system.

Core features include:standardized flanged design,enabling quick installation and disassembly,reducing on-site construction time;superior airtightness,with multi-layer sealing structure and leak-proof flanged joints;precise quantitative control,adjustable feeding/discharging rate via variable speed drive;durability,with wear-resistant blades and corrosion-resistant flanges extending service life;wide adaptability,suitable for dry powders,granules,and small lumps such as cement,grain,chemical powder,and coal.

It is widely applied in environmental protection,chemical,cement,metallurgy,food,and pharmaceutical industries.Typical applications include ash discharge of bag dust collectors,material feeding in pneumatic conveying pipelines,and silo unloading.The flanged design makes it easy to integrate with existing equipment,making it a versatile choice for industrial production lines.

In summary,the flanged rotary airlock valve combines airtight isolation,quantitative feeding,and convenient installation.Its standardized flanged connection and reliable performance make it an indispensable component in bulk material handling systems,ensuring stable production and efficient material conveying.
