Abstract

The invention relates to a push type space low-temperature gas generation device. The push type space low-temperature gas generation device comprises a solid module and a liquid module; the solid module and the liquid module can slide oppositely; the solid module comprises a medicine column shell; a weak spot is arranged on a shell of the liquid module; the liquid module is filled with a reactionsolution; and by pressing the liquid module, the medicine column shell penetrates through the weak spot on the liquid module to enter the liquid module. Meanwhile, the invention also relates to a usemethod of the push type space low-temperature gas generation device. The push type space low-temperature gas generation device and the use method thereof have the following advantages: the push type space low-temperature gas generation device is simple in structure, lightweight and convenient to move and use; meanwhile, an electric signal is not needed, and gas can be produced only by mechanical pressing; furthermore, the device is safe in component, generates low-temperature gas, avoids pollution to the reaction product and is suitable for space engineering.

Description

technical field [0001] The invention relates to the technical field of low-temperature gas generation in space, in particular to a press-type low-temperature gas generation device in space and a method for using the same. Background technique [0002] In space activities, gas is an important material. In recent years, a large number of applications of various inflatable structures in space engineering have greatly increased the amount of gas used. [0003] The high-pressure gas cylinder inflation device widely used in space engineering has the disadvantages of large mass, complex structure, and large volume. Compared with small / miniature inflation structures, its economy is poor. However, the currently used ground gas production device uses pyrotechnics to generate high-temperature gas, which is dangerous and not suitable for space engineering. [0004] Therefore, it is of great significance to develop a low-temperature gas-generating device suitable for space engineering....
