Technical Field

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

[0002] Pressure piping refers to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Pressure piping is a part of a pipeline that is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluids. It is an assembly consisting of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports.

[0003] When the existing device is in use, it is usually carried out to detect the connection point of the pressure pipeline or to detect whether the pipeline is damaged or leaking by means of inflation at one end of the pipeline. However, under these detection methods, it is difficult to locate the location of the damage or leakage during actual use of the pipeline due to its excessive length. This results in the pipeline having to be replaced as a whole if it is damaged, and thus it is difficult to avoid the problem of high cost. The present device uses an inflation device to inflate air on one side of the pipeline and uses a gas flow meter to detect the location of the leakage to solve the problem of detection difficulty. Therefore, a pressure pipeline detection device that solves the above problem is needed. Utility Model Content

When there is a leak in the wall of the flow pipe 1, the leaked airflow flows into the inner cavity of the vent 5, and the airflow value is measured when passing through the gas flow meter 6.

[0022] In a preferred embodiment, the rubber layers 4 are arranged on both sides of the casing 2, and the inner wall sizes of the two rubber layers 4 are adapted to the outer wall size of the flow pipe 1. By arranging the rubber layers 4 on both sides of the casing 2 on the device, the casing 2 on the device is in contact with the outer wall of the flow pipe 1 by the rubber layer 4, and the inner wall of the rubber layer 4 is matched with the outer wall size of the flow pipe 1, so that the casing 2 on the device is just covered with the flow pipe 1 by the rubber layer 4.

[0023] In a preferred embodiment, a sealed environment is formed between the flow pipe 1, the casing 2, and the rubber layer 4, and the vent 5 is the only outlet of the sealed environment. A sealed environment is formed between the flow pipe 1, the casing 2, and the rubber layer 4 on the device, so that when airflow occurs in the sealed environment on the device, the vent 5 is needed to transport it outward, thereby making the vent 5 on the device the only air outlet.

By providing a measuring head on the outer wall of the gas flow meter 6 on the device, the gas flow meter 6 on the device uses the measuring head to measure the airflow flowing through the inner cavity of the vent 5, so that the device uses the gas flow meter 6 to obtain leakage data of the pipeline.

When there is a leak in the pipe wall of the flow pipe 1, the leaked airflow flows into the inner cavity of the vent 5, and then the airflow value is measured when passing through the gas flow meter 6, so that the staff can conveniently detect the leakage of the pipeline. Then, the gas flow meter 6, the central control device 13 and the camera 12 on the device are used in coordination with each other. When the gas flow meter 6 on the device detects the airflow value, the electrical connection relationship between the gas flow meter 6, the camera 12 and the central control device 13 is used to automatically start the shooting function of the camera 12, so that the camera 12 on the device can shoot and record the location of the cracks in the pipe wall, so as to facilitate the detection of the pressure pipeline.
