The double discharge valve mainly uses the switching of the upper and lower valves at different times so that there is always a layer of valve plates in the middle of the equipment in the closed state to prevent the air from flowing. If it is under positive pressure delivery, the pneumatic double-layer air lock valve can also play a role in balancing and boosting the flow of the booster valve, so that the device can continuously pulsate the feed and also have the function of air lock to meet the pneumatic force Requirements for conveying powder and granular materials.
