[0002] With the rapid development of urbanization and the improvement of residents' living standards, heating systems have become an indispensable infrastructure in modern life. As the main channel for heat energy transmission, the safety and stability of the heating network are of vital importance. However, in actual operation, due to material aging, improper installation, external force damage and other reasons, the heating network often has leakage problems, such as the background technology problems raised by the utility model patent with application number 202221552532.2, which not only affects the heating effect, but also may cause waste of resources and environmental pollution.

[0003] In order to solve the leakage problem of the heating pipe network, various sealing devices and anti-leakage measures are used in the prior art. For example, some sealing devices use elastic materials or sealants for sealing, which are prone to aging or failure under high temperature, high pressure or long-term operation, resulting in reduced sealing effect. In addition, some anti-leakage measures require regular inspection and maintenance of the pipe network, which not only increases maintenance costs, but may also cause leakage accidents due to untimely maintenance.

[0004] Therefore, it is necessary to develop a new type of heating pipe network leakage prevention device for heating and heating. Utility Model Content
