This invention belongs to the field of rocket-based combined cycle engine testing technology. It discloses an experimental device for measuring the condensed phase distribution within a single-sided expansion nozzle under rocket mode. The device includes a two-phase flow gas generator connected to an ignition system. The two-phase flow gas generator simulates the rocket operating mode of a rocket-based combined cycle engine and generates high-pressure, high-temperature gas containing condensed phases.

This utility model belongs to the technical field of chromatographic analysis. It discloses a liquefied gas sampling device for chromatographic analysis, including a sample inlet, a liquid injection valve, a transparent quantitative loop, a vaporization valve, a sample vaporization bottle, a sample outlet valve, and a sample outlet. It adopts a four-valve group pipeline collaborative structure. The layout of the liquid injection valve, purge valve, vaporization valve, and outlet valve forms a complete cleaning and sampling closed loop. During cleaning, by reasonably switching the valve state, residual impurities in the pipeline can be quickly discharged. This avoids the cumbersome operation and contamination risk caused by the separation of the cleaning loop and sampling loop in traditional devices. At the same time, the clear division of the valves makes the process of "cleaning-sampling-vaporization-detection" smoother, reduces manual operation steps, and lowers the probability of sample distortion due to operational errors.
