Detailed Description
As shown in fig. 1, a shutoff valve for a discharge port of a storage bin for powder filling isostatic compaction molds comprises a storage bin 1 and a shutoff valve, wherein the shutoff valve comprises a valve body 2.1, a locking switch 2.2, a valve core 2.3 and a driving part, the valve body 2.1 is connected to the discharge port of the storage bin 1 through the locking switch 2.2, the valve core 2.3 is rotatably arranged in the valve body 2.1 through the driving part, a discharge baffle of the valve body 2.1 and a discharge port of the valve body 2.1 are arranged at the bottom of the valve body 2.1, a cavity communicated with the discharge port of the storage bin 1 is arranged in the valve core 2.3, a discharge baffle of the valve core 2.3 and a discharge port of the valve core 2.3 are arranged at the bottom of the cavity, and the valve core 2.3 is driven by the driving part, and the discharge baffle of the valve core 2.3 can close or open the discharge port of the valve body 2.1.
The shutoff valve is used for real-time compensation of powder closure after blanking is finished during isostatic pressing vibration charging operation, and can realize no overflow and throwing of materials and no dust pollution in the charging process, so that the charging operation is more reliable, safer and more efficient. When in use, the valve body 2.1 is extended into the isostatic compaction mould, in the embodiment, the outer diameter of the valve body 2.1 is round, so that the valve body is convenient to form a tight fit with the feed inlet of the isostatic compaction mould.
