A kind of synchronous valve for balanced discharge of satellite bicomponent propellant parallel storage tanks and its application

Abstract

The invention discloses a synchronous valve for balanced discharge of satellite dual-component propellant parallel storage tanks and its application. The synchronous valve includes a valve body. The left and right ends of the valve body are respectively connected to an inlet joint A and an inlet joint B. A main valve is arranged inside the valve body. The left and right ends of the main spool are respectively provided with the main spool spring A and the main spool spring B, the constant pressure difference valve assembly is provided under the main spool, and the constant pressure difference valve assembly is provided at one end of the constant pressure difference valve assembly. Spring, the lower end of the valve body is connected to the outlet joint; the application is to use the synchronous valve in the dual-component propellant parallel storage tank equalization discharge system of the liquid attitude and orbit control power system. The invention not only can adapt to various flow conditions, but also has the advantages of simplifying the power system and no matching and debugging of the system, and is especially suitable for a balanced discharge system of propellant parallel storage tanks.

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
