Liquid collector for surface tension storage tank

Abstract

The invention relates to a liquid collector for a surface tension storage tank. The liquid collector can be used for collecting the liquid in the storage tank and preventing the pressurized gas from entering a pipeline channel and is applied to the technical field of the propellant under the space microgravity environment. The liquid collector comprises more than two small supporting cylinders, a collector mesh piece, two collector pressure bearing plates, a collector chamber support and connecting pipes; the collector mesh piece is placed between the two collector pressure bearing plates; the lower collector pressure bearing plate is located on the collector chamber support; a space which is defined by the lower collector pressure bearing plate and the collector chamber support serves as a collection chamber; one ends of the small supporting cylinders and the upper collector pressure bearing plate are fixedly welded together; the storage tank is placed at the other ends of the small supporting cylinders; the collector mesh piece is in welding connection with the two collector pressure bearing plates; the lower collector pressure bearing plate is in welding connection with the collector chamber support; the two connecting pipes are welded on the side walls of the collector chamber support respectively and communicated with the collection chamber.

Description

technical field [0001] The invention relates to a surface tension storage tank liquid collector, which can collect the liquid in the storage tank and prevent pressurized gas from entering the pipeline channel, and is used in the technical field of propellants in the space microgravity environment. 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 existing surface tension storage tanks in our country are all mesh type, which use the surface tension of the liquid to collect propellant through the screen, and at the same time preven...

AI Technical Summary

Problems solved by technology

Although some articles have been published in public contributions abroad, these documents are all about the principles and functions of the overall structure and devices of the storage tank. There is no description of the detailed structural design of the actual storage tank, and they cannot be used as the basis for the design of storage tanks in my country. , so it is necessary to carry out the detailed structural design of the small cavity collector suitable for the surface tension tank according to the actual needs of our satellites
