The utility model provides a portable modularized
nitrogen making
machine. The portable modularized
nitrogen making
machine comprises a gas inlet seat and a gas outlet seat, wherein the gas inlet seat and the gas outlet seat are respectively provided with a gas
inlet channel and a gas outlet channel; the air inlet end and the air outlet end of the adsorption module are respectively communicated with the air outlet end of the air
inlet channel and the air inlet end of the air outlet channel; the first connecting piece is detachably arranged at the air inlet end of the air
inlet channel in a sealing manner; the second connecting piece is detachably arranged at the air outlet end of the air outlet channel in a sealed mode. Pipeline connection among a
compressed air pipeline, an air inlet channel and an air inlet control valve is achieved through a first input channel, a first output channel and a first control cavity which are integrally integrated in a first connecting piece. And the second input channel, the second output channel and the second control cavity which are integrally integrated in the second connecting piece realize pipeline connection among the
nitrogen pipeline, the gas outlet channel and the gas outlet control valve, so that the number of
pipe fittings required by the nitrogen making
machine is greatly reduced, rapid installation of the
gas pipeline of the nitrogen making machine is realized, the production efficiency is improved, and the production cost is reduced. And connection points of gas pipelines can be reduced, and the gas leakage risk is reduced.
