Multi-channel switching valve

The utility model relates to the technical field of multi-channel material conveying, in particular to a multi-channel switching valve which comprises a valve body and opening and closing mechanisms, the valve body is provided with a valve cavity and two pairs of valve ports communicated with the valve cavity, the valve body is an integral box body, and each pair of valve ports is provided with one opening and closing mechanism. The opening and closing mechanism comprises a valve rod, a valve element and a driving assembly, the valve rod is arranged on the valve body, the valve element is arranged on the valve rod, and the driving assembly is configured to drive the valve rod to drive the valve element to move between the corresponding pair of valve ports relative to the valve body so that the valve element can open or close one of the valve ports. When the multi-channel switching valve is used in application scenes such as aluminum oxide production, the flow direction switching requirement of a plane pipelin
