Description

Technical Field

[0001] The utility model relates to the technical field of heating pipes, in particular to a leakage prevention device for a heating pipe network. Background Art

[0002] A heating network, also known as a heat pipe, is a network of heating pipes that connects the heat source to the building's heat inlet, starting from the boiler room, direct-fired engine room, and heating center. Multiple heating pipes form a network.

[0003] The flow meter installed on the pipeline will continuously monitor the flow of hot water flowing through the pipeline and compare it with the data under normal working conditions. The collected flow and pressure data will be input into the background control system for processing and analysis. Once the data analysis results show a possible leak, such as a sudden decrease or abnormal increase in flow accompanied by pressure fluctuations, the system will immediately trigger an alarm.

[0004] During use, the existing heating pipe network leakage prevention device is unable to perform leakage prevention detection on the corner connections of the pipes at both ends. The pipe corners are high-risk areas for leakage. Once leakage occurs in these places, a large amount of heat energy or transmission medium will be lost because it cannot flow through normal channels. In addition, the pipe corners are often located in some small spaces, resulting in leakage at the corner connections. It is impossible to discover and maintain them in time, resulting in interruption of heating or water supply, affecting the quality of life of users. Utility Model Content

[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0015] 1. The leaked gas or liquid will be sealed in the bellows by the sealing ring, causing the bellows to expand and pull the magnet block 1 at one end to disconnect from the magnet block 2. The alarm will sound to remind the people around. The buffer spring set between the magnet block 2 and the magnet block 1 will buffer the airway at one end of the bellows, providing additional volume space, which can temporarily accommodate more leaked gas, reduce the amount directly discharged to the outside, and prevent the leaked gas or liquid from bursting the bellows.

[0016] 2. Place the clamping ring onto the mounting ring 1 so that the protrusion on one side of the mounting ring 1 is clamped into the groove on the heating pipe. Press the button to drive the slide bar downward to push the clamp to squeeze the reset spring piece. Align the clamp with the slot and rotate the mounting ring 2 to merge with the mounting ring 1. The compressed reset spring piece will push the clamp to clamp and fix it in the slot.
