Detailed Product Overview

The BHF Ash Rotary Valve is a standardized professional discharge valve widely adopted in thermal power boiler ash handling fields. Different from general rotary valves, it features a reinforced heavy-duty housing, thickened wear-resistant rotor vanes and precision sealing clearance, specially customized for boiler fly ash, bottom ash and high-temperature flue dust. The multi-pocket rotor structure realizes volumetric quantitative feeding, achieving continuous and uniform material discharge without surge flow or material blockage.

With excellent pressure isolation performance, the BHF rotary valve stably isolates the negative-pressure dust collecting system and positive-pressure conveying pipeline, eliminating pressure loss and dust back suction that affect boiler dust removal efficiency. The whole machine adopts fully enclosed dust-proof and heat-resistant structure, protecting internal bearings and transmission parts from fine ash erosion and high-temperature aging. Equipped with reliable electric drive system, it supports long-term 24-hour continuous operation and automatic system linkage, greatly reducing manual maintenance and system failure rate.

Core Product Advantages

Professional BHF Standard Design: Compliant with power plant boiler ash handling standards, dedicated for boiler flue ash discharging with highly matched structural parameters and working performance.
Excellent Airlock & Pressure Isolation: Precision machining clearance and multi-vane sealing structure maintain stable system pressure, effectively stop air backflow and flue gas leakage in negative pressure systems.
High Temperature & Abrasion Resistance: Heavy-duty wear-resistant rotor and heat-resistant structural design adapt to long-term scouring of high-temperature boiler ash, resisting deformation and abrasion.
Continuous & Uniform Discharging: Volumetric rotary feeding ensures stable and quantitative ash output, avoiding material accumulation, bridging and pipeline blockage.
Dust-proof & Long Service Life: Fully enclosed protective structure prevents fine ash from entering transmission components, reducing wear and extending equipment service life.
Low Failure & Easy Maintenance: Mature and optimized structural design with stable operation performance, fewer vulnerable parts and convenient daily inspection and replacement.

Application Scope

Mainly used for thermal power plant boiler ash handling, boiler flue dust discharge, dust collector hopper discharging, ash silo feeding and pneumatic conveying systems. It is the standard matching equipment for continuous discharging and air-lock isolation of boiler fly ash, bottom ash and fine industrial dust.
