Example Embodiment

[0021] Such as figure 1 A liquid full display device for satellite propellant filling is shown, which is placed upstream of the gas filling and exhaust valve of the satellite storage tank during the filling process. When the storage tank is filled with propellant, the propellant will be removed from the storage tank. The gas port overflows and flows into the liquid full display device through the gas filling and exhaust valve and filling pipe. Under the action of buoyancy, the float will be floated. During the floatation process, the non-magnetic stainless steel tube will be caused by the magnetic force. The orpiment switch in the middle is closed, and outputs a closed signal to the control system, so that the control system judges that the storage tank is full. The device includes the following components: device inlet 1, floating ball 2, device cavity 3, non-magnetic stainless steel pipe 4, flange 5, device outlet 6, bolt 7, connecting piece 8, sealing gasket 9, floating ball ...

Abstract

The invention provides a full-liquid displaying device for filling a propellant for a satellite. The full-liquid displaying device for filling the propellant for the satellite comprises an inlet, a floating ball, a cavity, a non-magnetic-conductivity stainless steel pipe, a flange, an outlet, a bolt, a connecting part, a sealing gasket and a floating ball limiting device. In light of that the traditional single-component propelling system is to be fully filled with the propellant and soaked in the propellant, the propellant flows back until reaching a specified filling volume after a liquid film is formed at a propellant management device for a storage box, the way to display whether a storage box is full of the propellant is the key of filling the propellant into the single-component propelling system, and to determine the state of filling the propellant into a single-component satellite, the full-liquid displaying device is provided to display whether the storage box is full of the propellant, and thus the full filling state of the storage box can be tested and displayed. The full-liquid displaying device for filling the propellant for the satellite has the advantages that the structure is simple, the damage is difficultly caused, the reliability is improved, the service life is prolonged, the difficulty at processing is small, the processing cost is decreased, the stainless steel materials selected for all parts are compatible with the propellant I, and meanwhile, the expansibility is improved.

Description

technical field [0001] The invention relates to a liquid full display device for satellite propellant filling, which is an important device used in the process of satellite propellant filling, and is suitable for propellant filling tests of all fully managed surface tension storage tanks. Background technique [0002] At present, the chemical propulsion system for in-orbit flight is mainly divided into single-component satellite propulsion system and dual-component satellite propulsion system, which can be used for geostationary orbit satellite platforms to perform north-south position maintenance, attitude control (momentum wheel unloading) and orbit control, as well as synchronization. tasks such as track transfer. In addition, the chemical propulsion system can also complete tasks such as precise attitude control of satellites and micro-satellites, and satellite constellation network control. [0003] The single-component satellite propulsion system generally adopts a fu...
