高压管路快速连接件设计与应用

Design and application of a quick connector for high pressure pipe

管路连接操作在液体火箭发动机组件液流试验中非常频繁,为了提高试验效率、降低试验过程中密封件的损耗,需要将现用的连接方式进行改进,而高压快速连接接头在国内市场并没有成品。因此,结合实际操作对液流试验用的连接接头进行了重新设计,并经过不断改进和验证,达到了快速、可靠的连接目的。

Pipe connection operations are frequently conducted during fluid tests for liquid rocket engine components tests. For higher test efficiency and less consumption of seals improved method for pipe connection is needed. Proper products are not available in domestic market for high pressure pipe quick connection. Thus a new type of quick connector for liquid rocket engine components fluid tests is developed. Tests results show that the new design meets the requirement of quick and reliable pipe connection.
