Dry ash gate valve is utilized for entering pipelines and discharging pipelines. A flashboard exists inside the body, connecting with lift structure. Chamber closing to the flashboard connects with chamber of flashboard. There is a ribbed slab between the flashboard and the discharging channel. Discharging port on ribbed slab avoids occlusion. Dry ash gate valve has the advantages of convenient operation, reliable sealing and long service life, mainly used for transporting system in thermal to deliver dry ash, fly ash, cement, etc.
