Problems solved by technology

[0003] At present, aerospace product systems generally have high-pressure working conditions. At present, the connection of ground system pipelines still adopts threaded or flange connection. When the system changes, it is necessary to disconnect or connect the pipeline joints through tools. When there is time requirement and the system changes frequently Under working conditions, the existing pipeline connection methods are inefficient and cumbersome to operate. At the same time, under various changing working conditions, there are certain requirements for pressure tolerance. In the case of ensuring no dripping, a plugging efficiency is required. Taller, more reliable quick-connect couplings

Abstract

An ultrahigh-pressure zero-dripping-leakage quick connector comprises a first connector assembly (1), a second connector assembly (2), a connector clamping ring (3), a position-clamping steel ball (4), a connector baffle ring (5) and a sealing ring (6). Full sealing of the connector is achieved through butting of the first connector assembly (1) and the second connector assembly (2) and the sealing ring (6); automatic locking of the connector after the butting process is achieved through the connector clamping ring (3), the position-clamping steel ball (4) and the connector baffle ring (5); during releasing of butting, the connector clamping ring (3) is rotated, so that the connector automatically quits a locking state; and in the situation of ensuring zero-dripping-leakage, a shell and internal devices of the connector assemblies are made of high pressure resistant materials, liquid transportation under the high pressure and airtight conditions is ensured, stability is high, and the structure is simple.

Description

technical field [0001] The invention relates to an ultra-high pressure zero-drip quick joint, which belongs to the field of launch vehicle pipeline connection. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. When the frequency of plugging and unplugging of connectors in the system is high, quick connectors are needed to ensure installation efficiency. The quick connector is divided into two butt joints, each of which is guaranteed to be sealed in the disconnected state. After the connection, the internal medium is connected, and the external is guaranteed to be sealed. [0003] At present, aerospace product systems generally have high-pressure working conditions. At present, the connection of ground system pipelines still adopts threaded or flange connection. When the system changes, it is necessary to disconnect or connect the pipeline joints through tools. When there is time requirement and the system cha...
