Description

TECHNICAL FIELD

[0001] The utility model relates to hot melt joint leakproofness monitoring technical field, concretely is a kind of hot melt joint leakproofness monitoring device. BACKGROUND

[0002] The connection of PE pipe is the most important process in the whole PE pipe installation process, and the advantages and disadvantages of the connection technology are directly related to the service life of the pipeline. Hot melt connection is usually used. Ultrasonic phased array detection technology is a non-destructive testing method using ultrasonic waves. It realizes the detection of target objects through a plurality of independently controlled ultrasonic transducer arrays. The wedge in ultrasonic phased array detection is used to help the sound beam emitted by the ultrasonic probe enter the detected material. Among them, Chinese patent number: CN201920064322.0 discloses a water bag wedge phased array probe for detecting PE pipe hot melt joint. The water bag wedge solves the problem that ultrasonic waves cannot be refracted into the weld, increases the refraction angle, and thus solves the problem that PE pipe cannot be detected well, improving the quality of PE pipe hot melt joint detection.

[0003] Based on the above, the present inventors found that the water bag wedge can increase the refraction angle, but cannot detect the sealing condition of the hot melt joint in real time, and cannot take protective measures for the leaking hot melt joint in time. UTILITY MODEL CONTENT

[0007] Further, the upper end of the air bag is provided with a pressing disc corresponding to the position of the push plate.

[0008] Further, the cross-sectional diameter of the plugging member is greater than that of the movable hole.

[0009] Further, the color-developing transparent tube is threadedly connected with the through hole, and a sealing strip is arranged between the color-developing transparent tube and the through hole.

[0010] Further, the lower sleeve adapter is connected with the upper sleeve adapter through bolts.

[0011] Compared with the prior art, the hot melt connector sealing monitoring device has the following advantages:

[0012] (1) When the hot melt connector on the hot melt pipeline leaks, the air bag expands, drives the plugging member to move towards the glue box, opens the opening of the glue box, and the leak repair glue in the glue box flows into the operation groove, so that the air bag and the hot melt connector are wrapped with the leak repair glue, and after the leak repair glue hardens in the operation groove, a complete sealing member is formed, thereby further sealing and protecting the hot melt connector in time, providing a buffer time for the subsequent maintenance work of the operator; the expansion will squeeze the color-developing gas in the operation groove, which will be released through the cross-shaped seal designed by the system and flow to the color-developing transparent tube; once the color-developing gas enters the color-developing transparent tube through the cross-shaped seal, the active ingredients in the gas will react with the color-developing indicator strip in the tube; the inspector can observe the color change of the color-developing indicator strip in real time through the color-developing transparent tube. This observation is not only intuitive and simple, but also can quickly provide important information to help the inspector judge whether the current environment meets the safety standard and whether there are potential hazards. Therefore, the change of the color-developing indicator strip can be regarded as a warning mechanism to remind the worker to pay attention to safety; the design of this system not only improves the safety of the working environment, but also enhances the warning ability of the operator to potential problems, so that appropriate responses can be taken when working to ensure the smooth progress of the working process.
