description	The utility model belongs to the technical field of blowback devices, and discloses a disassembly-free maintenance blowback device of a Ba differential pressure flow instrument sampling system, which comprises a first air pipe, a first limiting groove is arranged at the lower end of the first air pipe, and a first limiting column is movably connected with an inner cavity of the first limiting groove. The rear end of the first limiting column is fixedly connected with a first spring, and the rear end of the first spring is fixedly connected with a connecting plate. According to the utility model, the valves of the blow-off pipe group and the pressure drawing pipe group which are connected with the second air pipe are opened, then the blower is started to blow air into the inner cavity of the blow-off pipe group through the first air pipe, the connecting pipe and the second air pipe, and then the air takes away stains in the inner cavity of the blow-off pipe group and flows to the inner cavity of the pressure d
