Zusammenfassung:The utility model discloses an overpressure multi-protection mechanism for a gas heat distribution pipeline, which relates to the technical field of heat supply and comprises a connecting pipe, two sides of the connecting pipe are fixedly connected with connecting cylinders, the outside of the connecting pipe is communicated with a fixed cylinder, the outside of the fixed cylinder is communicated with a pressure relief pipe, and a gas leakage component is arranged in the fixed cylinder. When the device is used, the middle of the heat distribution pipeline needs to be installed firstly, the connecting cylinder is inserted into the heat distribution pipeline after installation, then the elastic air bag is inflated through the inflation pipe, the elastic air bag is inflated and expands at the moment, the sealing gasket can be driven to be attached to the inner wall of the heat distribution pipeline, and the gap between the connecting cylinder and the inner wall of the heat distribution pipeline is filled; due to
