[0017] In this embodiment: it includes an outer shell 1, and by arranging a plurality of outer shells 1 on the outside of the pipeline, the outer shell 1 is fixed on the outside of the pipeline, so that various positions of the pipeline can be detected, and the connection between the outer shell 1 and the pipeline can be achieved by welding or the like. The outer shell 1 includes an outer cylinder 11, an annular side plate 12 and an inner cylinder 13. The diameter of the inner cylinder 13 is smaller than the diameter of the outer cylinder 11. The outer diameter of the annular side plate 12 is the same as the inner diameter of the outer cylinder 11. The two annular side plates 12 are fixedly connected to the two ends of the outer cylinder 11. The two annular side plates 12 are parallel to each other, and the distance between the two annular side plates 12 matches the length of the inner cylinder 13. The two ends of the inner cylinder 13 are respectively fixedly connected to the two annular side plates 12, and the inner cylinder 13 and The outer cylinders 11 are not in contact with each other, and the central axes of the inner cylinder 13 and the outer cylinder 11 are located on the same straight line. The inner cylinder 13 is located on the inner side of the outer cylinder 11. The outer cylinder 11, the annular side plate 12 are connected to form a closed space between the outer cylinder 11 and the inner cylinder 13. The outer cylinder 11, the annular side plate 12 and the inner cylinder 13 are an integrated structure. A cavity 14 is provided between the outer cylinder 11 and the inner cylinder 13. The cavity 14 is annular. A cavity 2 15 is provided between the inner cylinder 13 and the pipeline. When the outer cylinder 1 is fixed to the outside of the pipeline, the gap between the inner cylinder 13 and the pipeline forms the cavity 2 15. A ventilation groove 131 is provided on the top of the inner cylinder 13. When the pipeline inside the inner cylinder 13 leaks, the leaked gas will enter the cavity 2 15. The outer cylinder 11 is provided with a transparent water storage tank 2 on one side, and the transparent water storage tank 2 is fixed on one side of the outer cylinder 11. The transparent water storage tank 2 and the cavity 14 are both provided with clean water 141. The clean water 141 in the cavity 14 is located in the lower half of the cavity 14, and the clean water 141 inside the transparent water storage tank 2 is also located in the lower half of the transparent water storage tank 2. Since the transparent water storage tank 2 and the cavity 14 are both in a closed state, although the clean water 141 inside the cavity 14 and the transparent water storage tank 2 will vaporize and then liquefy with the change of temperature, the total amount of the clean water 141 will not be significantly reduced. The cavity 14 and the transparent water storage tank 2 are connected by a triangular guide pipe 3. The flow guide pipe 3 includes a connecting pipe 1 31 and a connecting pipe 2 32. The connecting pipe 1 31 is connected to the connecting pipe 2 32. The connecting points of the connecting pipe 1 31 and the connecting pipe 2 32 are both their highest points. Therefore, the other ends of the connecting pipe 1 31 and the connecting pipe 2 32 are connected to the clean water 141. When the leaked gas enters the cavity 14, if the gas is insoluble in water, the gas will increase the air pressure inside the cavity 14 after entering the cavity 14. As the air pressure continues to increase, the clean water 141 in the cavity 14 will enter the interior of the transparent water storage tank 2 through the triangular flow guide pipe 3, thereby significantly increasing the liquid level of the clean water 141 inside the transparent water storage tank 2. If the gas is soluble in water, the gas will decrease the air pressure inside the cavity 14 after entering the cavity 14.As the air pressure continues to decrease, the clean water 141 inside the transparent water tank 2 will be sucked into the cavity 14 through the triangular guide tube 3, and the liquid level of the clean water 141 inside the transparent water tank 2 will be significantly reduced, so that the presence of a leak in the pipeline can be detected directly through the change in the liquid level of the clean water 141 inside the transparent water tank 2, which is convenient for intuitively discovering gas leaks and facilitating timely determination of the location of gas leaks. At the same time, the leaked gas can be intercepted by the outer shell 1 and the transparent water tank 2 to prevent the leaked gas from directly entering the air and causing adverse effects on the external environment and the health of the staff.
[0018] The side of the annular side plate 12 away from the outer cylinder 11 is fixedly connected to the outer side of the pipeline, and the diameter of the inner cylinder 13 is larger than the inner diameter of the annular side plate 12; during installation, the annular side plate 12 can be fixed to the outer side of the pipeline by welding or the like, and when the central axis of the inner cylinder 13 and the annular side plate 12 are located on the same straight line, the inner cylinder 13 does not contact the pipeline.
[0019] One side of the outer cylinder 11 is provided with a plurality of connection blocks 111, and one side of the transparent water storage tank 2 is fixedly connected to the plurality of connection blocks 111; through the connection of the connection blocks 111, the position between the transparent water storage tank 2 and the outer cylinder 11 is fixed.
[0020] The connecting pipe 1 31 is fixedly connected to the connecting pipe 2 32 , and the connecting pipe 1 31 is symmetrical to the connecting pipe 2 32 ; the connecting pipe 1 31 and the connecting pipe 2 32 have the same structure, and the clean water 141 can flow between the connecting pipe 1 31 and the connecting pipe 2 32 .
[0021] The lower end of the connecting pipe 1 31 is located inside the cavity 14, and the lower end of the connecting pipe 2 32 is located inside the transparent water tank 2; the connecting pipe 1 31 passes through the side wall of the outer cylinder 11, and the connecting pipe 2 32 passes through the side wall of the transparent water tank 2, and there is no gap at the connection between the triangular guide pipe 3 and the transparent water tanks 2 of the outer cylinder 11.
[0022] The working principle and use process of the utility model are as follows: during use, when the pipeline on the inner side of the inner cylinder 13 leaks, the leaked gas will enter the cavity 2 15, and then enter the cavity 14 through the ventilation groove 131 above. If the gas is insoluble in water, the gas will increase the air pressure inside the cavity 14 after entering the cavity 14. As the air pressure continues to increase, the clean water 141 in the cavity 14 will enter the interior of the transparent water storage tank 2 through the triangular guide tube 3, thereby significantly increasing the liquid level of the clean water 141 inside the transparent water storage tank 2. If the gas is soluble in water, the gas will reduce the air pressure inside the cavity 14 after entering the cavity 14. As the air pressure continues to decrease, the clean water 141 inside the transparent water storage tank 2 will be sucked into the cavity 14 through the triangular guide tube 3, and the liquid level of the clean water 141 inside the transparent water storage tank 2 will be significantly reduced.
