Description

Technical Field

[0001] The utility model relates to the technical field of boiler equipment safety, in particular to a boiler pipeline leakage detection device. Background Art

[0002] With the development of industrial production, the safe operation of boiler pipelines is of vital importance. However, boiler pipelines may leak during long-term operation. If they are not discovered and handled in time, they will pose a serious threat to production safety. Pipeline leakage detection can be divided into direct leak detection methods and indirect methods. The direct method is to use the detection elements preset outside the pipeline to directly measure the leaking medium, so as to repair the pipeline according to the leaking part. The pressure detection method is used to detect the pipeline, and the pressure change in the pipeline is used to analyze whether there is a leak in the pipeline.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing pressure is used to detect the pipeline, the pipe body is often detected. However, since the pipeline joints are often connected by flanges, the flanges are sealed with sealing rings installed at the interfaces when connected. The sealing rings are easily damaged after long-term use, affecting the sealing of the flange joints, thereby causing pipeline leakage. The existing monitoring methods are not convenient for detection at flange joints, and the structural settings of some pipeline leakage detection devices are unreasonable. When the package is installed on the pipeline, it is inconvenient to operate and requires the collaboration of multiple people, which is difficult to operate.

[0004] Therefore, the utility model provides a boiler pipeline leakage detection device. Utility Model Content

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 5As shown, a boiler pipeline leakage detection device comprises a semicircular upper shell 1, a pressure gauge 5 is fixedly installed in the middle of the upper shell 1, and the left and right ends of the upper shell 1 are rotatably connected with a first lower shell 2 and a second lower shell 3 of a quarter circle, respectively, and the lower ends of the first lower shell 2 and the second lower shell 3 are connected by a locking mechanism 4, and the upper shell 1, the first lower shell 2 and the second lower shell 3 form a circular ring with a cavity inside; the docking position of the upper shell 1 and the first lower shell 2, the docking position of the upper shell 1 and the second lower shell 3, the docking position of the first lower shell 2 and the second lower shell 3, the front and rear end head inner wall positions of the upper shell 1, the front and rear end head inner wall positions of the first lower shell 2 and the front and rear end head inner wall positions of the second lower shell 3 are all provided with a sealing layer of rubber material; the upper shell 1 and the first lower shell 2, and the upper shell 1 and the second lower shell 3 are all rotatably connected by hinges; when in use, the upper shell 1 is first placed on the detection position, and then the first lower shell 2 and the second lower shell 3 are buckled together, so that one person can operate it, which is more convenient to use.

[0028] The locking mechanism 4 includes a hook 41 fixedly mounted on the first lower shell 2 and a rotating block 42 fixedly mounted on the second lower shell 3, a rotating plate 43 is rotatably connected to the rotating block 42, a hanging frame 44 is rotatably connected in the middle of the rotating plate 43, and the other end of the hanging frame 44 is hung on the hook 41; the rotating plate 43 is set to an arc shape opposite to the arc of the outer surface of the second lower shell 3, so as to facilitate the buckling and grabbing when the rotating plate 43 is rotated to be close to the surface of the second lower shell 3.

[0029] The sealing layers of the front and rear end heads of the upper shell 1, the front and rear end heads of the first lower shell 2, and the front and rear end heads of the second lower shell 3 are all provided with end head inner wall sealing patterns 6 to ensure sealing performance in contact with the outer wall of the pipeline; the sealing layers of the two end faces of the upper shell 1, the two end faces of the first lower shell 2, and the two end faces of the second lower shell 3 are all provided with docking surface sealing patterns 7 in the middle position, and the front and rear sides of the docking surface sealing patterns 7 are provided with docking surface end head sealing patterns 8 to ensure the sealing performance of the docking surface.
