[0016] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0017] As Figure 1 shown, an auxiliary device for installing a deflector plate is used to install the deflector plate in the valve body of a single crystal furnace.

[0018] The auxiliary device includes

[0019] an auxiliary positioning plate 1, which is a hollow cylindrical plate with openings on both the upper and lower sides. A positioning groove for the deflector plate to be embedded is formed on the circumferential outer wall of the auxiliary positioning plate 1, and a gap for the deflector plate to pass through is left between the outer wall of the auxiliary positioning plate 1 and the inner wall of the valve body.

[0020] There are two types of positioning grooves, which are respectively defined as the first positioning groove 2 and the second positioning groove 3. Among them, the first positioning groove 2 is a horizontal groove, and the second positioning groove 3 is an inclined groove. Moreover, the length of the first positioning groove 2 is longer than that of the second positioning groove 3, and the width of the first positioning groove 2 is consistent with the width of the second positioning groove 3.

[0021] There are several first positioning grooves 2, which form an array of positioning groove groups. Each group of positioning groove groups is distributed side by side along the circumferential direction of the auxiliary positioning plate 1. The first positioning grooves 2 in the same group of positioning groove groups are distributed vertically, and the adjacent two first positioning grooves 2 in the same group of positioning groove groups are staggered.

[0022] Positioning holes are also provided on the auxiliary positioning plate 1. There are two positioning holes in total, which are respectively located on both sides of the auxiliary positioning plate 1. At the same time, positioning protrusions corresponding to the positioning holes are also provided on the inner wall of the valve body. By designing the positioning holes on both sides of the auxiliary positioning plate 1, it is convenient to fix the relative position between the auxiliary positioning plate 1 and the valve body, providing a basis for the subsequent positioning and installation of the deflector.

[0023] The outer contour line of the positioning hole is formed by connecting the first arc segment 4, the second oblique line segment 5, the third arc segment 6, the fourth arc segment 7, and the fifth oblique line segment 8 in sequence. The second oblique line segment 5, the third arc segment 6 and the fourth arc segment 7, the fifth oblique line segment 8 are symmetrically distributed on both sides of the bottom end of the first arc segment 4, and the second oblique line segment 5, the third arc segment 6, the fourth arc segment 7 and the fifth oblique line segment 8 are distributed in a V shape. For the design of the shape of the positioning hole, a positioning hole formed by connecting the first arc segment 4, the second oblique line segment 5, the third arc segment 6, the fourth arc segment 7, and the fifth oblique line segment 8 in sequence is adopted, and the second oblique line segment 5, the third arc segment 6 and the fourth arc segment 7, the fifth oblique line segment 8 distributed in a V shape are matched. When positioning with a positioning hole designed in this shape, the positioning and fixing between the positioning plate and the valve body can be better realized, avoiding loosening and affecting the accuracy of the installation positions of the deflectors.

[0024] When installing each deflector, first, align the positioning holes on the auxiliary positioning plate 1 with the positioning protrusions on the valve body to realize the relative fixation of the position between the auxiliary positioning plate 1 and the valve body. Then, according to the position of the deflector to be installed, select the corresponding deflector to cooperate with the corresponding first positioning groove 2 or second positioning groove 3. After passing the deflector through the first positioning groove 2 or the second positioning groove 3, the position of the deflector is positioned, and then the deflector is welded and fixed to the inner wall of the valve body to complete the positioning and installation of the deflector.
