[0005] Furthermore, the fixing plate is a steel plate.

[0006] Furthermore, the fixing nut is fixed to the front edge of the fixing plate by welding, and the connecting nut is fixed to the back center of the fixing plate by welding.

[0007] Furthermore, the fixed plate is a square structure.

[0008] Furthermore, there are four fixing nuts, which are respectively arranged in the middle positions of the four sides of the fixing plate of the square structure.

[0009] The utility model provides a regulating valve grinding device, which cooperates with the power output of an electric drill to increase the relative grinding speed of the workpiece and improve the problems of slow grinding speed and low efficiency. At the same time, the electric drill can be used to easily correct the center during the process of driving the valve seat to rotate, thereby alleviating the problems of large shaking and eccentricity in manual grinding.
