First, by driving one of the rotating rods 17 close to the second retaining ring 14 to rotate, the rotating rod 17 drives the gear 18 to rotate, and the gear 18 drives the second gear ring 16 to rotate. The second gear ring 16 pushes the first gear ring 15 to rotate it. At this time, the other gears 18 are rotated by the rotation of the first gear ring 15 and the second gear ring 16, driving the double-headed screw 19 to rotate, so that the two fixing plates 191 threaded on the double-headed screw 19 move toward each other, thereby fixing the flange 12 on the opposite sides of the valve body 1 and the pipe 11, avoiding shaking when installing the valve body 1 and the pipe 11, and improving the subsequent installation efficiency.

[0020] The first snap ring 13 and the second snap ring 14 are fitted together at a common connecting shaft 2. The first snap ring 13 and the second snap ring 14 are rotatably mounted on the connecting shaft 2. A connecting plate 21 is fixedly mounted at the fitting part on the other side of the first snap ring 13 and the second snap ring 14. A fixing hole 22 is provided in the middle of the two connecting plates 21.

[0021] By adopting the above technical solution, by setting the connecting shaft 2, the connecting plate 21 and the fixing hole 22, the staff fixes the fixing holes 22 on the first clamping ring 13 and the second clamping ring 14 with screws, thereby facilitating their installation on the valve body 1.

[0025] By adopting the above technical solution and setting the limit rod 4, the fixing plate 191 is prevented from deflecting during movement, thereby improving its stability and better fixing the flange 12 on the opposite side of the valve body 1 and the pipeline 11.

[0026] The double-headed screw 19 and the limiting rod 4 are both fixedly mounted with a limiting block 5 at one end away from the gear 18 .

[0027] By adopting the above technical solution and providing the limit block 5 , the fixing plate 191 is prevented from falling off the double-headed screw 19 .

[0030] There are six rotating rods 17 and six limiting rods 4 .

[0031] By adopting the above technical solution and setting the number of rotating rods 17 and limiting rods 4 to six, the flanges 12 on the opposite sides of the valve body 1 and the pipeline 11 can be fully fixed, thereby improving the fixing effect and reducing shaking during installation.

[0032] The flange 12 on the opposite side of the valve body 1 and the pipeline 11 is located between the two fixing plates 191.

[0033] By adopting the above technical solution, it is convenient for the fixing plate 191 to fix the flange 12.

[0034] Working principle: First, by driving one of the rotating rods 17 close to the second clamping ring 14 to rotate, the rotating rod 17 drives the gear 18 to rotate, the gear 18 drives the second gear ring 16 to rotate, and the second gear ring 16 pushes the first gear ring 15 to rotate. At this time, the other gears 18 rotate through the rotation of the first gear ring 15 and the second gear ring 16, driving the double-headed screw 19 to rotate, so that the two fixing plates 191 threaded on the double-headed screw 19 move toward each other, thereby fixing the flanges 12 on the opposite sides of the valve body 1 and the pipeline 11, avoiding shaking when installing the valve body 1 and the pipeline 11, and lifting Subsequent installation efficiency; by setting the connecting shaft 2, the connecting plate 21 and the fixing hole 22, the staff fixes the fixing holes 22 on the first clamping ring 13 and the second clamping ring 14 with screws, so as to facilitate its installation on the valve body 1. After the valve body 1 and the pipeline 11 are installed, they can also be disassembled to facilitate the next use; by setting the stabilizing ring 3 and the stabilizing groove 31, when the stabilizing ring 3 in the second clamping ring 14 starts to rotate, the stabilizing ring 3 enters the stabilizing groove 31 in the first clamping ring 13, thereby pushing the stabilizing ring 3 in the first clamping ring 13 to rotate, so that the first gear ring 15 can be rotated, and the multiple gears 18 can be rotated.
