[0019] The technology of the present invention will now be described with reference to the accompanying drawings of the embodiments thereof.

[0020] The solution is described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-3 As shown, an embodiment of this utility model proposes a gate valve mating flange pipeline installation tool, including a fixed turntable 1;

[0022] A rotating rod 7 is fixedly installed in the middle of one side of the fixed turntable 1. Multiple evenly distributed strip-shaped openings 2 are opened on the surface of one side of the fixed turntable 1. A square moving block 3 is installed in each strip-shaped opening 2. A positioning pin 4 is fixedly installed in the connecting hole at one end of each square moving block 3. Multiple evenly distributed adjusting screw holes 12 are opened on the outer wall of the fixed turntable 1. An adjusting stud 13 is threadedly connected in each adjusting screw hole 12. One end of each adjusting stud 13 is rotatably connected to the surface of the corresponding square moving block 3, and a knob 14 is fixedly installed at the other end of each adjusting stud 13.

[0023] Each positioning pin 4 has an external thread 5 engraved on one side of its outer wall, which is threaded to the corresponding limit nut 6. Each knob 14 has anti-slip texture engraved on its outer wall. A hexagonal disassembly block 8 is fixed in the middle of the outer wall of the rotating rod 7, and a connecting ring 9 is fixed on one side of the outer wall of the rotating rod 7. Multiple evenly distributed connecting posts 10 are fixed on the outer wall of the connecting ring 9. A rotating ring 11 is fixed on the outside of the multiple connecting posts 10. Limiting grooves 15 are opened on both sides of the outer wall of the strip opening 2. A limiting slider 16 is slidably connected in each limiting groove 15. Limiting sliders 16 are fixed on both sides of each square moving block 3. An installation slot 17 is opened on one side of each strip opening 2. A scale 18 is fixed in each installation slot 17. An indicator block 19 is fixed on the other side of the outer wall of each positioning pin 4.

[0024] Working principle: When using this installation tool, the operator can adjust the tool according to the new model of the threaded flange. Turning the knob 14 will drive the adjusting stud 13 in the adjusting screw hole 12, which will move the square moving block 3. The limit slider 16 connected to the square moving block 3 can slide in the limit slide groove 15. The positioning pin 4 connected to the square moving block 3 is connected to the marking block 19. By calibrating the marking block 19 with the scale 18, the adjustment distance can be determined. After adjusting the position of the positioning pin 4 and aligning it with the threaded flange, the operator loosens the limit nut 6 and inserts the positioning pin 4 into the flange hole. Then, the threaded interface of the threaded flange and the threaded oil pipe can be connected. The rotating ring 11 will drive the rotating rod 7, which will drive the fixed turntable 1 to rotate, and thus drive the threaded flange to rotate. At the same time, the installation tool can be used to rotate the rod 7 to ensure that the threaded flange and the threaded oil pipe are tightly connected.
