Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] Such as figure 1 The working principle and filling process of the liquid hydrogen filling system are shown. It can be seen from the figure that it includes a pressurization module, a liquid hydrogen storage module, a valve module, a filling system, an exhaust system and an external receiving system;

[0028] Boosting module: pressurize and vaporize liquid hydrogen to generate low-temperature hydrogen, and transmit the low-temperature hydrogen to the liquid hydrogen storage module and liquid hydrogen discharge system;

[0029] Liquid hydrogen storage module: receives the hydrogen from the pressurization module, and transmits the liquid hydrogen to the filling system through the valve module through the extrusion of hydrogen, and outputs the hydrogen vaporized into the filling system during the transmission of the liquid hydrogen to the fil...

Abstract

The invention discloses a liquid hydrogen loading system and relates to the field of low-temperature medium loading and transferring systems. The liquid hydrogen loading system comprises a pressurizing module, a liquid hydrogen storage module, a valve module, a loading system, a liquid hydrogen discharge system and an external receiving system. According to the liquid hydrogen loading system, through adoption of the liquid hydrogen extruding loading technology, the liquid hydrogen loading key equipment redundancy design, the loading flow distributing and adjusting technology, the pipeline flexible design, the liquid hydrogen propellant quality assurance technology and the like, purposes that the maximum pipeline drift diameter is DN150, the liquid hydrogen loading volume is 430 m<3>, the maximum loading flow is about 8,000 L / min and two storage tanks of a rocket can be loaded simultaneously are achieved, the safety and the reliability of a ground loading system are guaranteed, and the reliability of the liquid hydrogen loading system and the overall capability of a low-temperature loading system are improved.

Description

technical field [0001] The invention relates to a cryogenic medium filling and transmission system, in particular to a liquid hydrogen filling system. Background technique [0002] The traditional liquid hydrogen filling system is an important part of the low-temperature filling system of liquid launch vehicles. Its main function is to complete the first-stage and second-stage liquid hydrogen storage tanks of the rocket on time, quantitatively, and with guaranteed quality during the prescribed launch procedures. Pre-cooling, filling, refilling, and refilling before injection can realize safe and reasonable discharge of liquid hydrogen and hydrogen gas, and release liquid hydrogen back when necessary. At present, the liquid hydrogen filling system of a satellite launch center in my country uses two 100m 3 The liquid hydrogen vehicle refuels the rocket, the pipeline diameter is DN75, and the refilling volume is about 45m 3 , The maximum filling flow rate is 1000L / min. The f...
