Gas outlet assembly suitable for high-purity nitrous oxide purifier

The utility model provides a gas outlet assembly suitable for a high-purity nitrous oxide purifier, which comprises a main outer pipe, an auxiliary outer pipe, a limiter, a first connecting column, a second connecting column, a connecting plate, a fixing bolt, a first one-way valve, a second one-way valve and an external thread, and the limiter is nested between one end of the main outer pipe and one end of the auxiliary outer pipe; a first connecting column and a second connecting column are welded to the middle of the surface of one end of the main outer pipe and the middle of the surface of one end of the auxiliary outer pipe respectively, and a connecting plate is connected between the first connecting column and the second connecting column through fixing bolts. When the gas outlet assembly is connected with an external pipeline, the problem of leakage can be effectively avoided, and meanwhile, the problem that external gas easily enters from the gas outlet assembly can be effectively avoided, so that th
