High-pressure oxygen stamping pipeline

The high-pressure oxygen stamping pipeline comprises a machine body and a connecting block, a plurality of sets of sealing air pipes are evenly installed on the surface of the top of the machine body, and adjusting screw rods are fixedly installed on the surfaces of the tops of the sealing air pipes. By adopting the flow limiting plate and the fastening piece, in the actual use process, the connecting pipe can be rapidly fixed to the surface of equipment needing to be filled through the fastening piece, gas filling is facilitated, the fastening piece can be locked through the fastening handle after fixing is completed, gas leakage is prevented, and the connecting pipe is convenient to use. The stability and the air tightness of the device are improved, in the filling process, the flowing speed of gas can be effectively slowed down through the flow limiting plate, due to the fact that the surface of the flow limiting plate is bent, when the gas flow passes through, a small part of the gas flow can be reserved,
