Satellite dual-component propellant parallel storage tank equalization discharge synchronous valve and application thereof

Abstract

The invention discloses a satellite dual-component propellant parallel storage tank equalization discharge synchronous valve and application thereof. The synchronous valve comprises a valve body; theleft end and the right end of the valve body are connected with an inlet joint A and an inlet joint B correspondingly; a main valve element is arranged in the valve body; the left end and the right end of the main valve element are provided with a main valve element spring A and a main valve element spring B correspondingly; a constant pressure difference valve assembly is arranged under the mainvalve element; a constant pressure difference valve element spring is arranged at one end of the constant pressure difference valve assembly; and the lower end of the valve body is connected with an outlet joint. According to the application, the synchronous valve is applied to a liquid attitude rail control power system dual-component propellant parallel storage tank equalization discharge system. The synchronous valve can adapt to various flow conditions, has the advantages that a power system can be simplified and system matching debugging is not needed, and is especially applicable to propellant parallel storage tank equalization discharge systems.

Description

technical field [0001] The invention relates to the field of attitude and orbit control of satellite liquid propulsion, in particular to a synchronous valve for balanced discharge of dual-component propellant parallel tanks of satellites and its application. Background technique [0002] The liquid attitude and orbit control power system is one of the key technologies of rockets, satellites, missiles, and kinetic energy weapons. It mainly includes high-pressure gas sources, decompression systems, propellant storage tanks, propellant control solenoid valves, and engines. As far as the propellant management technology is concerned, the two parallel storage tanks in the same group in the bicomponent propulsion system have different pressures on the propellant and fuel due to the differences in pipeline flow resistance and the structure of the tank isolation membrane. It will cause the unbalanced storage output of the two storage tanks of the same component, causing the center o...

Problems solved by technology

[0005] Although the electronic control method has been used to manage the propellant, it needs to realize the functions of accurately measuring the remaining propellant, actively controlling the balanced discharge of parallel storage tanks, and actively controlling the mixing ratio of the system. There are too many components used, and the electronic control method is currently in the It is still in the research and development stage in China. At present, only ground test research has been done, and it has not been actually used in models.

[0006] To sum up: the prior art has the problem that many components are used, which leads to complicated pipelines of the power system
