The valve plate of the flap valve is automatically opened under the gravity of the material. After the material falls, the counterweight lever system automatically resets the valve plate to prevent the wind from blowing in, thus completing the material transportation. There are mainly single and double door flap valves. The double flap valves mainly use the switches of the upper and lower valves at different times to keep a layer of valve plates in the middle of the device in a closed state to prevent air turbulence. If it is under positive pressure delivery, the pneumatic double-lock valve can also play the role of balance and booster valve to achieve the function of continuous pulsating feeding and locking gas to meet the pneumatic force. Requirements for conveying powder and granule materials.
The double-layer heavy hammer flap valve adopts mechanical transmission, the transmission is stable, no impact, no fault, less replacement parts and reliable use. The valve is divided into upper and lower layers. When working, the upper valve is first opened by mechanical transmission. The upper valve is closed by the balance weight. Then the lower valve is opened by the mechanical transmission, and the lower valve is closed by the balance weight, thus completing the first ash discharge cycle. The double-layer ash discharge valve is an ideal ash discharge valve in metallurgical, non-ferrous and environmentally-friendly dust removal equipment. Heavy hammer flap valves are widely used in building materials, metallurgy, chemical, electric power and other industries. The heavy hammer flap valve is used as a hopper discharge device for various types of equipment and a feeding and discharging device for various mills, dryers, silos, etc. to prevent wild wind from blowing in.
