[0006] After the first pipeline is connected to the pressure-guiding pipe through the adapter, a clearing rod is inserted into the pressure-guiding pipe and rotated to drill through the pressure-guiding pipe. At the same time, the pressure of the medium in the pressure-guiding pipe is used to discharge the blockage in the pressure-guiding pipe, and the blockage is discharged to the outside through the second pipeline through the first pipeline, thereby quickly and effectively clearing the blockage in the pressure-guiding pipe.

[0007] According to a preferred implementation aspect of the utility model, the first pipeline is fixedly connected to the second pipeline, and the first pipeline is perpendicular to the second pipeline.

[0013] According to a preferred implementation aspect of the utility model, an insertion tip is provided at one end of the first rod portion away from the second rod portion, and the insertion tip is used to insert the first rod portion into the pressure-inducing tube.

[0014] According to a preferred implementation aspect of the utility model, the central axis of the ferrule joint and the central axis of the first pipe are located in the same horizontal direction, and the inner wall of the ferrule joint fits the outer wall of the first rod portion, thereby ensuring that the ferrule joint effectively seals the end of the first pipe away from the pressure-inducing pipe, thereby preventing the blockage from leaking directly out of the first pipe.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] Reference Figure 1 The present embodiment is a clearing device for a pressure gauge pressure pipe, comprising a clearing rod 1, a flow diversion interface 2 and an adapter 3. The clearing device in the present embodiment is made of stainless steel as a whole.

[0022] Further, the flow diversion interface 2 of this embodiment includes a ferrule joint 21 and a first pipe 22 and a second pipe 23 that are interconnected. The first pipe 22 is fixedly connected to the second pipe 23 and the first pipe 22 is perpendicular to the second pipe 23. One end of the first pipe 22 is connected to one end of the adapter 3, and the other end of the adapter 3 is connected to the pressure-inducing pipe to connect the first pipe 22 and the pressure-inducing pipe. Specifically, in this embodiment, the inner wall of the first pipe 22 is provided with an internal thread (not shown), and the outer wall of the adapter 3 is provided with an external thread (not shown), and the first pipe 22 is threadedly connected to the adapter 3 and the pressure-inducing pipe.

[0023] The other end of the first pipe 22 is fixedly connected to the ferrule joint 21, the central axis of the ferrule joint 21 and the central axis of the first pipe 22 are located in the same horizontal direction, and the inner wall of the ferrule joint 21 fits the outer wall of the first rod 11, ensuring that the ferrule joint 21 effectively seals the end of the first pipe 22 away from the pressure-inducing pipe, and preventing the blockage from leaking directly outward from the first pipe 22. The second pipe 23 is used to discharge the blockage flowing from the pressure-inducing pipe to the first pipe 22, and the volume of the cavity in the second pipe 23 is set to be greater than or equal to the volume of the cavity in the first pipe 22, ensuring that the blockage entering the first pipe 22 from the pressure-inducing pipe can enter the second pipe 23 in a timely and rapid manner and be discharged outward from the second pipe 23, avoiding the accumulation of blockage inside the first pipe 22.

[0024] Furthermore, the dredging rod 1 includes a first rod portion 11 and a second rod portion 12 that are fixedly connected, the first rod portion 11 is perpendicular to the second rod portion 12, and the first rod portion 11 is parallel to the first pipe 22. The first rod portion 11 passes through the end of the ferrule joint 21 away from the adapter 3 and the end of the first pipe 22 away from the ferrule joint 21, and the end of the first rod portion 11 away from the second rod portion 12 is also provided with an insertion tip 111, which is convenient for the first rod portion 11 to be inserted into the pressure-inducing pipe. The length of the first rod portion 11 is greater than the length of the second rod portion 12, and the second rod portion 12 serves as a rotating handle to drive the first rod portion 11 to rotate in the pressure-inducing pipe. In addition, the length of the first rod portion 11 is greater than the sum of the lengths of the ferrule joint 21, the first pipe 22 and the adapter 3, so as to ensure that the end of the first rod portion 11 away from the second rod portion 12 can extend outside the adapter 3, thereby ensuring that the first rod portion 11 can enter the pressure-inducing pipe when the second rod portion 12 is rotated.

[0025] The inner diameter of the first pipe 22 is larger than the outer diameter of the first rod 11, and the ratio of the outer diameter of the first rod 11 to the inner diameter of the first pipe 22 is 1:2.9-3.8. In this embodiment, the outer diameter of the first rod 11 is 6 mm, and the inner diameter of the first pipe 22 is 19 mm, so as to avoid the inner wall of the first pipe 22 from fitting with the outer wall of the first rod 11, and ensure that there is enough space between the inner wall of the first pipe 22 and the outer wall of the first rod 11, so that the blockage flowing out of the pressure-inducing pipe can flow smoothly into the first pipe 22, and then enter the second pipe 23 from the first pipe 22, and be discharged outward from the second pipe 23.

[0026] The working process of the blockage clearing device of this embodiment is as follows:

[0027] Close the ball valve of the pressure gauge's pressure pipe and disassemble the pressure gauge. Thread the first pipe 22 of the clearing device to the adapter 3, and then connect the other end of the adapter 3 to one end of the pressure gauge's pressure pipe. Insert the insertion tip 111 of the first rod 11 into one end of the pressure pipe, and rotate the second rod 12 so that the second rod 12 gradually enters and penetrates the pressure pipe. At the same time, use the medium (water) pressure in the pressure pipe to make the blockage in the pressure pipe enter the first pipe 22 and the second pipe 23, and then be discharged outward. Finally, rotate the second rod 12 to slowly pull out a part of the first rod 11 outward, close the ball valve of the pressure pipe, and after there is no leakage in the second pipe 23, completely remove the clearing device from the pressure pipe, reinstall the pressure gauge, open the ball valve, and restore the measurement state.

[0028] The blockage clearing device of the utility model can realize rapid and effective clearing of blockage in the pressure-inducing pipe, and can also prevent dirt in the pressure-inducing pipe from splashing onto workers and causing harm to the workers.

[0029] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
