The utility model relates to a sealing packing injection gun of a heating pipeline compensator, which comprises an ultra-high pressure oil cylinder, a gun barrel, a handwheel, an injection nozzle and an on-off valve. The injection nozzle which is provided with screw threads can be connected with the compensator. An oil supply system comprises a hand-operated oil pump and a reversing valve without using power supply. The oil cylinder is provided with great supercharging ratio. Operating pressure can be rapidly reached. The gun barrel can be rapidly assembled and disassembled through the handwheel, which is convenient for feeding fillers. After injection, pressure maintenance can be realized through the on-off valve. The whole device has the advantages of simple structure, easy use, assembly and disassembly, flexibility, rapidness, reliability, small volume, light weight, and convenient carrying. The utility model is in particular suitable for the operation requirements of emergency rescue and leakage protection in the installation and the use of the telescopic heating pipeline compensator.
