Anti-leakage fire-fighting equipment against pressure relief force internally and externally

The invention discloses anti-leakage fire-fighting equipment against pressure relief force internally and externally. The anti-leakage fire-fighting equipment structurally includes an upper column head, branch pipes, connecting port covers, a vertical column and a base. The upper column head and the branch pipes are welded together and internally communicate with each other. The lower ends of thebranch pipes relative to the upper column head are welded to the vertical column, and the base is fixed to the bottom of the vertical column. The branch pipes are mechanically sealed with the connecting port covers, and the branch pipes are internally provided with pipe interlayers, extrusion surface assemblies, water flow channels, connecting textures, connecting pipes and adjusting mechanisms. The extrusion surface assemblies and the adjusting mechanisms are arranged in the pipe interlayers in a matched mode, and the connecting textures are arranged at the ends, close to the extrusion surface assemblies, of the wate
