Its main functions are: • Control material flow; • Achieve air lock (prevent gas backflow); • Play a role in unloading (especially for dust removal systems, pneumatic conveying systems, etc.). ⸻ 🔧 Working principle of flap valve Flap valve is usually composed of **upper flap, lower flap, valve body, transmission mechanism (cylinder or electric), etc., and its working process is as follows: ✅ Basic structure: +----------------+ | Upper flap | | | | | | Lower flap | +----------------+ ⸻ 🌀 Working process (taking double-layer flap valve as an example): 1. Initial state: upper flap is closed and lower flap is open; 2. Feeding stage: • The upper flap is opened, and the material falls from the silo or conveying equipment into the middle cavity; • The lower flap is closed at this time to lock the air; 3. Discharging stage: • The upper flap is closed to prevent more material from falling; • The lower flap is opened, and the material that has fallen into the cavity is discharged; 4. Repeat cycle: • The upper and lower flaps act alternately to achieve continuous unloading and maintain air tightness. ⸻ ⚙️ Driving mode: • Pneumatic drive (commonly used, fast response); • Electric drive (for precise control); • Heavy hammer/manual type (simple structure, suitable for infrequent operation); ⸻ ✅ Advantages of flap valve • Realize intermittent unloading but continuous air lock; • Simple structure, easy maintenance; • Suitable for high temperature, dusty and other working conditions; • Effectively prevent gas backflow or pressure fluctuation in pneumatic conveying system. ⸻ 🏭 Typical applications • Bag filter unloading; • Pneumatic conveying system; • Coal powder, dust, powder conveying system; • Powder/granular material unloading in grain, coffee beans, building materials and other industries. ⸻ If you are designing or selecting a flap valve, I can recommend suitable structural forms and parameters according to your working conditions (material type, temperature, pressure, etc.).
