[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] like Figure 1-Figure 5As shown, a high-pressure ball valve flange includes a ball valve body 1, which is provided with a plurality of first mounting holes 11 and second mounting holes 12. The first mounting holes 11 and the second mounting holes 12 are both through-mounted mounting holes. A first accommodating groove 22 is provided on one side of each of the first mounting holes 11 and the second mounting holes 12. A second accommodating groove 22 and a third accommodating groove 23 that cooperate with the limit pin 3 are provided in the first accommodating groove 21.

[0027] Specifically, the first mounting hole 11 and the second mounting hole 12 are placed on a wall of the ball valve body 1 , which is circular in shape. The first mounting hole 11 is placed above the second mounting hole 12 and arranged in a vertical row.

[0028] In this embodiment, the first accommodating groove 21 is placed on the right side of the first mounting hole 11 and the second mounting hole 12, and the second accommodating groove 22 in the first accommodating groove 21 is placed above the third accommodating groove 23, also arranged in a vertical row, and the center hole position of the second accommodating groove 22 is parallel to the center hole position of the first mounting hole 11, and the center hole position of the third accommodating groove 23 is aligned with the center hole position of the second mounting hole 12.

[0029] Furthermore, the shape of the first accommodating groove 21 is a rectangle. Different from the rectangle of the first accommodating groove 21, the shapes of the second accommodating groove 22 and the third accommodating groove 23 are set to be the same square, and the depth of the second accommodating groove 22 and the depth of the third accommodating groove 23 are greater than the depth of the first accommodating groove 21, so as to facilitate the connection between the limit pin 3 and the second accommodating groove 22 or the third accommodating groove 23 to prevent the limit pin 3 from loosening and falling due to its too shallow depth.

[0030] The shape of the limiting pin 3 is set to be a square that is adapted to the second accommodating groove 22 or the third accommodating groove 23 , but the length of the limiting pin 3 is greater than the total depth of the second accommodating groove 22 or the third accommodating groove 23 .

[0031] Furthermore, in the present invention, there are at least four first mounting holes 11 and second mounting holes 12 , which are evenly arranged around the wall of the ball valve body 1 , and the first accommodating grooves 21 are provided with the same number as the first mounting holes 11 and the second mounting holes 12 .

[0032] In this embodiment, the first mounting hole 11 opened in the ball valve body 1 is adapted to be connected to a larger flange of our company, and the second mounting hole 12 is adapted to be connected to a smaller flange of our company, wherein the diameter of the first mounting hole 11 is equal to the diameter of the second mounting hole 12.

[0033] When the ball valve body 1 is installed with a flange of a larger size, the limit pin 3 is installed in the second receiving groove 22 of the first receiving groove 21 at any location, and based on the depth of the second receiving groove 22, the limit pin 3 will not loosen or fall off easily, but will be stably installed in the second receiving groove 22, and at least one end of the limit pin 3 is exposed to the outside of the ball valve body 1.

[0034] During the installation process, the larger flange is guided by the limit pin 3, and the mounting hole of the flange itself is aligned with the first mounting hole 11 of the ball valve body 1. The flange used in the present invention is provided with a square hole that is adapted to be connected with the limit pin 3. When the limit pin 3 is placed in any second accommodating groove 22 or third accommodating groove 23, the flange can be connected to the limit pin 3 through the square hole provided by itself, and the mounting holes between the flange and the ball valve body 1 can be aligned.

[0035] After the installation is completed, the limit pin 3 can be pulled out. The square hole provided in the flange is set to a square that is compatible with the limit pin 3 and is placed on one side of each installation hole provided in the flange itself.

[0036] Similarly, when the ball valve body 1 is installed with a smaller flange, the limit pin 3 is installed in the third receiving groove 23 of any first receiving groove 21. Under the guidance of the limit pin 3, the smaller flange is fixed with screws after the mounting hole of the flange itself is aligned with the second mounting hole 12 of the ball valve body 1.

[0037] Furthermore, a sealing ring 13 is provided on the outer wall of the ball valve body 1 , and the sealing ring 13 is mainly used to ensure good sealing and leak-proof performance after the ball valve body 1 and the flange are installed.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
