By providing the auxiliary device 5, first, manually rotate the turntable 3, so that the turntable 3 drives the circular shaft 2 to rotate, and the circular shaft 2 drives the valve inside the valve body 1 to rotate. When the valve rotates to the designated position, the inner wall of the turntable 3 coincides with the inner wall of any circular hole 53. At this time, under the reaction force of the spring in the spring rod 51, the spring rod 51 moves towards the circular ring 52. When the spring rod 51 moves to the position where it is inserted into the circular hole 53, the position of the turntable 3 is fixed, and then the positions of the circular shaft 2 and the valve inside the valve body 1 are fixed, so that the valve inside the valve body 1 can be rotated to any position for fixation, facilitating personnel to control the flow rate of the fluid inside the valve body 1 and improving the use efficiency and flexibility of the valve body 1.

At this time, manually move the circular hole rod 46 so that the circular hole rod 46 drives the bolt to move. When the screw rod 45 moves to the position where it inserts into and penetrates the interiors of the two circular hole plates 44, use a tool to rotate the nut 47 so that the nut 47 moves left and right along the surface of the screw rod 45. When the nut 47 moves to the position where it presses against the surface of the circular hole plate 44, the nut 47 cooperates with the circular hole rod 46 to squeeze and fix the two circular hole plates 44, so that the first protective cover 41 and the second protective cover 43 are fixed on the surface of the valve body 1 and cool the surface of the valve body 1 through the coolant inside it, while blocking the heat in the external environment, thus completing the auxiliary cooling and high-temperature resistance treatment of the valve body 1.

When the valve rotates to the designated position, make the inner wall of the turntable 3 coincide with the inner wall of any circular hole 53. At this time, under the reaction force of the spring in the spring rod 51, the spring rod 51 moves towards the direction close to the ring 52. When the spring rod 51 moves to the position where it inserts into the circular hole 53, the position of the turntable 3 is fixed, and further the positions of the circular shaft 2 and the valve inside the valve body 1 are fixed, so that the valve inside the valve body 1 can rotate to any position for fixation, thus completing the control of the flow rate inside the valve body 1.
