I produced the double hammer flap cinder valve steel plate welded structure leaves just wear good blade and shaft-type connector is compact and lightweight reliable energy conservation principle. Also known as electric double flap valve air lock feeder, driven by the drive rod through the crank gear, the cam and connecting rod respectively, driven by the upper and lower drive shaft rotates, the interaction is turned on, with the lever by the system to ensure reliable valve reset. Double electric lock flap valve to prevent the Wind, blowing wind, according to the frequency determined by the completion of the opening and closing system to discharge. Double flap valve, also known as double air lock valve is widely used in chemical, food, building materials, metallurgy, electric power and other industries. The equipment is mainly as a cyclone separator and dust as well as a variety of dryers, silos and other equipment for unloading device to prevent outside air to enter. The main advantage of the double air lock valve valve switch up and down at different times of the intermediate layer of the device is always cut off valve is in the closed state board to prevent air channeling. If you are under positive pressure conveying, pneumatic double lock valve can also play a role to help balance the flow and pressure valve, in order to reach the device that is able to continuously fluctuating feedstock but also has the function of locking gas to meet the Air Force delivery requirements of powder material. Rugged and compact design of the overall structure, stable and reliable, sophisticated appearance; valve plate and seat alternately switch, no sliding structure, strong sealing performance; exasperating of powder material conveying system, there can also be used for general discharge pressure pulsation materials occasions; flange shape can be round or square; simple structure, easy maintenance; good wear resistance, suitable for high temperature sealing; difficult to produce the card blocking phenomenon; polishing accuracy up to 300 #, suitable for conveying food grade materials; Users can choose according to the actual needs of a variety of body material: stainless steel, carbon steel, etc.; There are many ways to choose the drive: pneumatic, electric; the product characteristics and uses: a compact, smooth and reliable. Commonly used in building materials, metallurgy, chemical industry, electric power industry, as all kinds of dust removal equipment hopper unloading equipment and a variety of mills, dryers, silos and other equipment for unloading device.
