Problems solved by technology

[0004] The fiber cloth material used in the water tank of the existing space station is difficult to meet the requirements of antibacterial, mildew and flame retardant, which poses a threat to the health and safety of astronauts
The existing space station water tank is difficult to withstand high operating pressure, and it is difficult to ensure reliability under the extreme conditions (vacuum) of the space station
The water tank of the space station mostly uses metal parts that are in direct contact with water. Metal parts will chemically react with drinking water, resulting in changes in water quality, making it difficult to ensure long-term compatibility.

Abstract

The invention discloses a space station drinking water soft storage tank. The space station drinking water soft storage tank comprises an inner bag, an outer bag, a zipper, an elastic cord, a quick disconnecting device, reinforcing lines, a joint pipe, an outlet base, an inner bag water outlet, liquid level indicating strips, circumferential reinforcing strips and axial reinforcing strips. Axial surfaces of the outer bag and the inner bag are cylindrical, the outer bag is made of chitosan fiber cloth which belongs to non-metallic materials, the outlet base is made of nonmetal, and the inner bag is made of a nine-layer composite membrane material. The space station drinking water soft storage tank is simple in structure, detachable, good in compatibility with water, extremely high in gas barrier property and capable of being repeatedly used, and the outer bag and the inner bag of the water tank can be folded so that the storing space can be reduced.

Description

technical field [0001] The invention relates to a soft storage tank for drinking water in a space station, which is used as a container for astronauts in the space station. Background technique [0002] The space station drinking water soft tank is a container for the space station to store astronauts' drinking water added with silver ions. Therefore, in addition to meeting the leakage rate index and discharge efficiency index of general storage tanks, in addition to the specific functional requirements for space station soft storage tanks, it is also necessary to meet the compatibility test requirements with the above media, pressure resistance requirements and on-orbit use. Wait for other requirements. In order to reduce the storage space of the water storage container after evacuation, it is necessary to design a storage tank that can be folded for easy storage. Therefore, a storage tank that uses fiber cloth to make the outer bag and film material to make the inner bag ...
