Product Overview The flap valve is used as an ash hopper unloading device for various types of equipment, as well as a feeding and unloading device for various mills, dryers, silos, and other equipment, to prevent wild wind from blowing in. It is mainly driven by a heavy hammer, electric drive, and push rod. Operational principle The valve plate of the flap valve automatically opens under the gravity of the material. After the material falls, the counterweight lever system automatically resets the valve plate to prevent wild wind from blowing in, thus completing the transportation of the material. There are mainly single and double door flap valves, and double door flap valves mainly use the opening and closing of the upper and lower valves at different times to keep a layer of valve plates in the middle of the equipment in a closed and isolated state to prevent air flow. If it is under positive pressure transportation, the pneumatic double layer air lock valve can also serve as a balance and boost valve to assist flow, in order to achieve the equipment's ability to continuously pulse feed while also having the function of air lock, in order to meet the requirements of pneumatic transportation of powder and particle materials. Double layer heavy hammer The double-layer heavy hammer flap valve adopts mechanical transmission, with stable transmission, no impact, no faults, fewer replacement parts, and reliable use. The valve is divided into two layers: upper and lower. When working, the upper valve is first opened by mechanical transmission, and the upper valve is closed by balancing the counterweight. Then, the lower valve is opened by mechanical transmission, and the lower valve is closed by balancing the counterweight. This completes one ash unloading cycle. Double layer ash discharge valve is an ideal ash discharge valve in metallurgical, non-ferrous, and environmental dust removal equipment. The heavy hammer flap valve is widely used in industries such as building materials, metallurgy, chemical engineering, and power. The heavy hammer flap valve serves as an ash hopper unloading device for various types of equipment, as well as a feeding and unloading device for various mills, dryers, silos, and other equipment, to prevent wild winds from blowing in.
