Please refer to fig. 1 in detail.

When the material delivery valve is actually used, materials entering the box body 1 are blown away in time and cannot be accumulated at the position of the feeding pipe 2 due to the existence of the first air inlet pipe 4; the presence of the second inlet pipe 5 allows the material to be blown off in time and to be discharged from the outlet pipe 3, and allows space for the material to flow in the inlet pipe 2. Compared with the traditional feed valve, the feed valve omits a gear and a blade, and the inner arrangement of the valve body is simpler; and the first air inlet pipe 4 and the second air inlet pipe 5 are adopted to blow away and drive the materials in the valve body, so that the fluidization characteristic of the valve body is improved, and the blockage of the valve body is avoided.
