The invention relates to a liquid path expansion standard device facilitating extravehicular operation of astronauts. The liquid path expansion standard device comprises an expansion adapter and an expansion case. The expansion adapter is a passive end, is mounted on a spacecraft cabin and is launched along with the cabin; the expansion machine case is an active end and is installed on the expansion adapter through an astronaut going out of a cabin. The expansion adapter and the expansion case are connected through a machine, a circuit and a liquid path, the interfaces are standard interfaces, and the connection mode is irrelevant to the type of liquid path equipment installed in the expansion case, such as a pump assembly, a valve assembly, a working medium supplementing assembly and the like. The liquid path expansion standard device has the advantages that the connector is designed in a standardized mode, the device is suitable for an astronaut to operate on an extravehicular spacesuit, auxiliary tools are not needed, operation is easy, consumed time is short and the like, and extravehicular liquid path pressure leakage-free operation can be met.

    本发明涉及一种便于航天员舱外操作的液路扩展标准装置,包括扩展适配器和扩展机箱两部分;扩展适配器为被动端,安装在航天器舱体上,随舱发射;扩展机箱为主动端,由航天员出舱安装至扩展适配器上。扩展适配器和扩展机箱通过机械、电路和液路连接,这些接口均为标准接口,连接形式与扩展机箱内安装的液路设备类型无关,如泵组件、阀组件、工质补加组件等。本发明的液路扩展标准装置具有接口标准化设计、适应航天员身着舱外航天服操作、不需要辅助工具、操作简单、耗时短等特点,可以满足舱外液路带压无泄漏操作。
