[0002] The downward-spreading discharge valve is mainly used for bottom discharge, discharge, sampling and dead-zone-free shut-off operations of reactors, storage tanks and other containers. The bottom flange of the valve is welded to the bottom of the storage tank and other containers, thereby eliminating the phenomenon that the process medium usually remains at the container outlet. The discharge valve is designed with a flat bottom structure according to the actual needs, and provides two working modes: lifting and lowering.

When the discharge valve is in use, the length of the internal rolling structure cannot be adjusted, which causes the raw materials to accumulate inside the valve body.

[0004] For this reason, we propose a discharge valve which is convenient for discharge of materials. Utility Model Content
