[0002] Pipeline valves are devices used to control the direction, pressure, and flow of fluids in fluid systems. They are control components in pipeline fluid delivery systems, used to control the cross-section of pipeline passages and the direction of medium flow. They perform functions such as diverting flow, preventing backflow, stabilizing pressure, shutting off, regulating, throttling, checking, diverting flow, or providing overflow and pressure relief. Valves can become damaged over time, so they require regular maintenance or replacement.

[0003] At present, the two ends of the pipeline valve are usually fixed on the flange between the two pipes by bolts, and the flange between the two pipes is tightly clamped at the two ends of the valve. After the valve is removed, the staff needs to spend a lot of energy to place the two ends of the valve on the flange between the two pipes for docking operation. The labor intensity is high, which affects the replacement efficiency and needs to be improved. Utility Model Content

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The pipeline valve replacement auxiliary tool involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Example 1:

[0021] like Figure 1-4 As shown, a pipeline valve replacement auxiliary tool includes a base plate 1, and limit mechanisms 3 are provided on both sides of the top of the base plate 1. The limit mechanisms 3 include two positioning covers 31, and the two positioning covers 31 are located above both sides of the support plate 21. The tops of the two positioning covers 31 are each provided with an arc-shaped connecting ring 32, and one end of the bottom of the arc-shaped connecting ring 32 is hinged to one side of the top of the positioning cover 31, and the other end of the bottom of the arc-shaped connecting ring 32 is threadedly connected to a bolt 33, and one end of the bolt 33 is threadedly connected to the inside of the other side of the top of the positioning cover 31. Support frames 34 are fixedly connected to the two sides of the top of the base plate 1, and the top of the support frame 34 is fixedly connected to the bottom of the positioning cover 31. Pipes 7 and flanges 8 are provided on both sides above the support plate 21, and the number of pipes 7 and flanges 8 is two. One side of the two flanges 8 is fixedly connected to one end of the two pipes 7, and the other side of the two flanges 8 overlaps one side of the two expansion plates 26. The outer wall of the pipe 7 is arranged inside between the positioning cover 31 and the arc-shaped connecting ring 32.

[0022] In this embodiment, through the provision of the support frame 34, it is convenient to fix the positioning cover 31 and the base plate 1 together, and through the cooperation of the two positioning covers 31 and the arc-shaped connecting ring 32, it is convenient to be sleeved on the outer walls of the two pipes 7, and through the provision of the bolts 33, it is convenient to fix the positioning cover 31 and the arc-shaped connecting ring 32 together, thereby facilitating the installation of this tool on the outer walls of the two pipes 7, and facilitating the subsequent expansion and installation of the pipeline valve between the two pipes 7.

[0023] Example 2:

[0024] like Figure 1-4 As shown, a pipeline expansion mechanism 2 is provided above the base plate 1, and the pipeline expansion mechanism 2 includes a support plate 21, the support plate 21 is located above the base plate 1, and a guide groove 22 is provided on the top of the support plate 21. Two positioning blocks 25 are symmetrically slidably connected inside the guide groove 22, and two expansion plates 26 are provided above the support plate 21. The bottom of the two expansion plates 26 is fixedly connected to the top of the two positioning blocks 25. A reduction motor 23 is fixedly installed on the right side of the support plate 21, and the output end of the reduction motor 23 extends to the inside of the guide groove 22 and is fixedly connected to a bidirectional screw rod 24. The left end of the bidirectional screw rod 24 is rotatably connected to the left end of the inner wall of the guide groove 22, and the internal symmetrical threads of the two positioning blocks 25 are sleeved on the outer wall of the bidirectional screw rod 24. An electric telescopic rod 4 is fixedly installed in the middle of the bottom of the base plate 1, and the telescopic end of the electric telescopic rod 4 extends to the top of the base plate 1 and is fixedly connected to the middle of the bottom of the support plate 21. Guide rods 5 are fixedly connected on both sides of the bottom of the support plate 21, and the lower part of the outer wall of the guide rod 5 is slidably sleeved on the inside of the base plate 1.

[0025] In this embodiment, through the cooperation of the reduction motor 23 and the bidirectional screw rod 24, it is convenient to drive the two positioning blocks 25 to slide symmetrically inside the guide groove 22. The positioning blocks 25 also drive the two expansion plates 26 to move relative to each other to squeeze the flanges 8 at one end of the two pipes 7, so that the two flanges 8 expand outward. At this time, the staff places the two ends of the replaced pipeline valve above the two flanges 8, and then drives the support plate 21 and the two expansion plates 26 to move downward through the telescopic end of the electric telescopic rod 4. At the same time, the support plate 21 drives the guide rod 5 to move downward inside the base plate 1. The setting of the guide rod 5 facilitates vertical guidance of the support plate 21 and the two expansion plates 26, so that the two expansion plates 26 are moved downward to separate from one side between the two flanges 8, thereby facilitating the two ends of the pipeline valve to be placed between the two flanges 8 for docking operation.

[0026] Example 3:

[0027] like Figure 1-4 As shown, a power supply box 6 is fixedly installed at the bottom of the base plate 1, and a battery is provided inside the power supply box 6. The reduction motor 23 and the electric telescopic rod 4 are both electrically connected to the battery.

[0028] In this embodiment, the battery is provided to facilitate powering the reduction motor 23 and the electric telescopic rod 4, so that the tool does not need an external power supply when in use, making it convenient to use the tool outdoors or in places without power supply.

[0029] In summary, if Figure 1-4As shown, this is a pipeline valve replacement auxiliary tool. When replacing a new valve after the pipeline valve is disassembled, first move the two expansion plates 26 between the two flanges 8, and at the same time move the two positioning covers 31 to the bottom of the outer walls of the two pipes 7, and cover the arc-shaped connecting ring 32 above the pipe 7. At this time, use bolts 33 to connect one end of the arc-shaped connecting ring 32 to the positioning cover 31, and then the tool can be installed on the two pipes 7. Then, the output end of the reduction motor 23 drives the bidirectional screw rod 24 to rotate, so that the bidirectional screw rod 24 drives the two positioning blocks 25 to slide inside the guide groove 22, and the positioning blocks 25 drive the two expansion plates 26 to move relative to each other. Squeeze the flanges 8 at one end of the two pipes 7 so that the two flanges 8 expand outward. At this time, the staff will place the two ends of the replaced pipe valve above the two flanges 8. At the same time, the telescopic end of the electric telescopic rod 4 drives the pipe expansion mechanism 2 to move downward, and moves the two expansion plates 26 of the pipe expansion mechanism 2 downward and away from one side of the two flanges 8. At this time, the staff will synchronously move the pipe valve downward and place the two ends of the pipe valve between the two flanges 8 for docking operation, thereby facilitating the installation of the pipe valve. Then remove the bolts 33 between the two positioning covers 31 and the arc-shaped connecting ring 32, and the tool can be removed from the two pipes 7.
