Abstract
The utility model provides a sluice valve which comprises a valve body, a valve plate and a drive structure. The drive structure drives the valve plate to move. A valve cavity is formed in the valve body. Two installation plates, arranged oppositely, of the valve body are provided with two corresponding valve ports. The valve plate is arranged in the valve cavity and used for closing one valve port. The first end of the drive structure is arranged outside the valve body, and the second end of the drive structure extends into the valve cavity and is connected with the valve plate. According to the sluice valve, the valve plate is arranged in the valve cavity and used for closing one valve port, and the size of a motion channel of the valve plate of the sluice valve is increased in comparison with the mode of closing the two valve ports. When the valve plate is closed, powder can flow out from the other valve port, and therefore the phenomenon that the valve plate is difficult to open or close can be avoided.
