AI Technical Summary

Technical Problem

In existing technologies, the weight of gas-liquid connectors increases when docking with launch vehicles, leading to docking difficulties and interface tension. Furthermore, they have poor adaptability and cannot effectively balance the weight of connectors of different specifications and weights.

Method used

The launch vehicle gas-liquid connector is used to balance the gas path, including a gas source input end, a balanced gas supply output end, a balanced cylinder, a direct gas supply path, and a balanced gas supply path. The weight of the gas-liquid connector and pipeline is balanced by the cooperation of a pneumatic pressure reducing valve and a pressure stabilizing gas cylinder. The filling and discharging of the cylinder is controlled by a solenoid valve and an adjustable flow valve to maintain a constant output pressure.

Benefits of technology

It achieves stability of the weight of the gas-liquid connector and pipeline under the condition of rocket body swaying or sinking, avoids interface pulling force, adapts to connectors of different weights, and improves interface reliability and adaptability.

Abstract

本发明提供了一种运载火箭气液连接器平衡气路,包括气源输入端、平衡供气输出端、平衡气缸、直接供气气路、平衡气缸放气气路和平衡供气气路;直接供气气路和平衡气缸放气气路分别用于直接对平衡气缸进行充气和放气;平衡供气气路通过气控减压阀根据稳压气瓶中气体的压力对气源输入端输入的气体进行减压后输出,使输出气体的压力等于稳压气瓶中气体的压力,稳压气瓶中气体的压力值设置为能够平衡气液连接器及气液管路重量的压力。本发明还提供了该平衡气路的控制方法。本发明始终保持对气液连接器及气液管路重量的平衡,从而消除对箭上接口的牵扯力,稳定性强,可靠性高,并且能够适应不同重量的气液连接器;同时能够控制气液连接器的上升和下降。
