一种液体流动指示器
摘要：
本发明公开了一种液体流动指示器，主要用于观察液体火箭推进剂的流动状态，检查是否存在夹气现象。液体流动指示器主要由接管嘴、螺母、壳体、玻璃管、插管、管头、垫片等部分组成，液体推进剂由插管流入指示器内部并累计一定液位，通过玻璃管观察液体推进剂流动过程中是否有气泡。本发明结构简单、工作可靠，可以有效检测出液体推进剂流动状态。
摘要（英）：

The present invention discloses a liquid flowing indicator, which is mainly used for observing the flowing state of a liquid rocket propellant and checking whether the gas entrapment phenomenon exists. The liquid flowing indicator mainly comprises pipe connection mouths, a nut, a housing, a glass pipe, an inserting pipe, a pipe head, a gasket and other components, wherein a liquid propellant flows into the liquid flowing indicator through the inserting pipe and is accumulated to achieve a certain liquid level, and whether bubbles exist during the liquid propellant flowing process is observed through the glass pipe. The liquid flowing indicator of the present invention has characteristics of simple structure, reliable work, and effective liquid propellant flowing state detection.
