Corrosion-resistant fluorine-lined regulating valve

The utility model relates to the technical field of regulating valves, in particular to a corrosion-resistant fluorine-lined regulating valve which comprises a base and a valve body, a sealing cover is installed at the bottom of the valve body, a supporting rod is installed at the top end of the sealing cover, an annular scraping piece is installed at the top end of the supporting rod, and six reinforcing ribs are installed on the outer side of the top end of the supporting rod at equal intervals. And one end of the reinforcing rib is connected with one side of the annular scraping piece, a mounting frame is mounted at the top end of the valve body, a sealing box is mounted at the top end of the mounting frame, and a pump machine is mounted on one side of the mounting frame. After the sealing cover is dismantled from the bottom of the valve body, impurities accumulated in the valve body can flow out through the bottom end of the valve body, and in the process that the sealing cover is taken out of the valve b
