In addition, all embodiments can be used in combination with each other.

[0024] See also Figure 1 The utility model provides a flange joint leakage detection device in a noisy environment, comprising a circumferentially foldable wrapping portion 10, the wrapping portion 10 is used to wrap the flange joint, at least two noise sensors 20 are arranged on the wrapping portion 10, the noise sensors 20 are electrically connected to a display panel 30 respectively, the display panel 30 is connected to the wrapping portion 10, and the display panel 30 is used to receive the signal of the noise sensor 20 and display the detection result.

[0025] The above embodiment adopts a foldable design, which is easy to carry and store, and is suitable for various complex environments, especially for applications in noisy environments such as factories, and has important practical significance and application value. In addition, it is simple and convenient to use. The operator only needs to wrap the sound insulation cylinder around the flange joint and other pipe connection parts, and can view the test results through the display panel without professional skills.

[0026] In the above embodiment, the wrapping portion 10 includes a circumferential wrapping surface 11, both ends of the circumferential wrapping surface 11 are connected to a wrapping end surface 12, and the circumferential wrapping surface 11 and the wrapping end surface 12 are both made of Z-shaped folding material, so that the circumferential wrapping surface 11 and the wrapping end surface 12 can be folded in the same direction.

[0027] At the same time, a hole 13 is provided on the wrapping end surface 12. The hole 13 is formed when the wrapping end surface 12 wraps the flange joint. The hole 13 is used for allowing a pipe connected to the flange joint to pass through.

[0028] In some preferred embodiments, Figure 2As shown, the inner edge of the wrapped end surface 12 is connected to a rope loop 14, and a drawstring 15 is arranged in the rope loop 14. When in use, by tightening the drawstring 15, the wrapped end surface 12 of the wrapped portion 10 can be further made to fit closely to the pipeline to ensure sealing.

[0029] In some preferred embodiments, the rope loop 14 is made of rubber or leather material. The rope loop 14 is made of rubber or leather material, which has better tightness after wrapping, and can further make the wrapping end surface 12 of the wrapping part 10 close to the pipe to ensure sealing.

At the same time, the rope loop 14 is made of rubber or leather material, and has good tightness after wrapping. By tightening the pull rope 15, the wrapping end face 12 of the wrapping part 10 can be further made to fit tightly against the pipeline to ensure sealing and isolate external noise. Two noise sensors 20 are inserted into the wrapping part 10 to detect the leaking flange joint. By comparing the signal difference of the two noise sensors 20, it is possible to accurately determine whether there is a leak in the wrapping part. The display panel 30 is used to display the detection results. When a leak is detected, the display panel will give different levels of prompts according to the sensor detection results, which is convenient for the operator to find and deal with it in time.
