Abstract

The invention discloses a rotating disc type sanding valve which comprises an upper valve body. A cleaning hole is formed in the side face of a sand inlet of the upper valve body, a blockage removinghole cover is arranged at an opening of the cleaning hole, the blockage removing hole cover and the upper valve body are fixed through a hand screw, a lower valve body is connected to the lower face of the upper valve body, a tai ji plate is arranged between the upper valve body and the lower valve body, a rotating shaft is arranged inside the center of the lower valve body, the inner end of the rotating shaft is connected with the tai ji plate, a handle is fixedly connected to the outer end of the rotating shaft, a positioning ruler is installed on the lower face of the handle, and the positioning ruler, the upper valve body and the lower valve body are fixed relatively. According to the rotating disc type sanding valve, the shape of a sand outlet hole is changed, the problem that the rotating disc type sanding valve is low in adjusting accuracy is solved, the advantage that the rotating disc type sanding valve is convenient to adjust and save labor is retained, and the adjusting accuracy is improved.
