The application discloses a hot oil abrasion test equipment for a rolling friction sleeve of an electronic disconnector, which comprises a tool seat, a tool frame and a main shaft shafting, the friction sleeve is detachably connected to the main shaft shafting, an oil bath heating box for placing the friction sleeve is arranged on the tool seat, a driving piece for driving the main shaft shafting to rotate is arranged on the tool frame, a secondary friction assembly for cooperating with the friction sleeve is arranged on the oil bath heating box, a loading structure for providing a controllable loading force to the secondary friction assembly and accurately detecting the micro-abrasion displacement of the secondary friction assembly is arranged on the tool frame, and an eccentric posture adjusting structure for adjusting the relative position and angle of the secondary friction assembly is arranged on the oil bath heating box. The application solves the problem that the prior art lacks a special test equipment for the rolling friction sleeve of the electronic disconnector of a new energy vehicle, so that the high-temperature hot oil lubrication, rotating operation, controllable load and eccentric posture multi-parameter coupling working conditions of the real work cannot be reproduced synchronously.

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. A single-sided expansion nozzle has its inlet end connected to the outlet end of the two-phase flow gas generator to receive the high-pressure, high-temperature gas containing condensed phases output by the two-phase flow gas generator. An optical measurement system is provided, with transparent windows on both the two-phase flow gas generator and the single-sided expansion nozzle. The optical measurement system performs non-contact measurement of the condensed phase particles inside the two-phase flow gas generator and the single-sided expansion nozzle through these transparent windows. This invention achieves visualized, non-contact measurement of the condensed phase particle distribution and particle size within the single-sided expansion nozzle, providing experimental data support for engine design and optimization.

The utility model relates to the field of medical nursing appliances, and specifically discloses a multifunctional restraint glove. The wrist part has a buffer layer, the palm part has a transparent curtain piece, and the finger part is provided with an adjustable restraint bandage. The transparent curtain piece is connected with the palm part through a sub-mother zipper and a connecting groove, and can be conveniently opened and closed. The sponge gasket is used to disperse pressure, and the cylindrical cotton cloth structure of the elastic finger sleeve ensures peripheral circulation. The utility model realizes the unification of restraint and observation functions, and the wire inlet channel can guide one or multiple pipelines simultaneously. Compared with the traditional restraint glove, the utility model reduces the risk of skin damage while maintaining effective restraint, and is particularly suitable for critically ill patients who need long-term infusion or monitoring.

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.
