Light mesh-type surface tension storage tank

Abstract

The invention discloses a light mesh-type surface tension storage tank comprising a gas port, an upper half spherical head, a cylindrical section, an anti-sloshing cone, an exhaust cup, a middle bottom partition plate, a middle bottom collector, a collector connecting pipe, a middle connector, an air bubble trap, a liquid port and a lower half spherical head; the upper half spherical head is in argon arc welding with the cylindrical section, the gas port is in argon arc welding with the upper half spherical head, and the liquid port is in argon arc welding with the lower half spherical head; the middle bottom partition plate is welded together with the cylindrical section and the lower half spherical head and used for dividing the storage tank into an upper cabin and a lower cabin; the middle bottom collector is located on the middle bottom partition plate; the anti-sloshing cone and the middle bottom partition plate are welded and fixed together and located in the upper cabin of the storage tank; and the collector connecting pipe, the middle collector and the air bubble trap are connected to form a propellant management device and arranged in the lower cabin of the storage tank. The light mesh-type surface tension storage tank can be applied to various satellites and has the advantages of light weight, liquid sloshing inhibition, strong mechanical environment resistance capability and the like. After the height of the cylindrical section of the storage tank is modified, the volume of the storage tank can be expanded on the basis of not changing the installation way, so that serialization products can be formed.

Description

technical field [0001] The invention relates to a light-weight net-type surface tension storage tank, which is especially suitable for high-orbit satellites and deep-space detectors, and greatly improves their payload capacity. Background technique [0002] The propellant tank is one of the most important parts of the spacecraft. Its function is to store and manage the propellant. Under the specified flow and acceleration conditions, it provides the engine or thruster with air-free propellant. Its core component is the propellant management device (PMD). The surface tension storage tank is the most widely used propellant storage tank in the world at present, and it is divided into two types: mesh type and plate type. The first surface tension storage tanks are all mesh structures, which use the surface tension of the liquid to pass through the screen to collect the propellant while preventing the gas from entering the pipeline. The development of surface tension tanks bega...

These articles are all about the principles and functions of some overall structures and devices of the storage tanks. There is no description of the detailed structural design of the actual storage tanks, and they cannot be used as the basis for the design of storage tanks in my country. Therefore, storage must be carried out according to the actual needs of satellites in my country. Detailed structural design work for tanks
