PMD adopts the trap-deflector-accumulator structure, which is the most popular form at present, but the plate accumulator in the trap cannot meet the propellant management needs of my country's large storage tanks at that time
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 detailed structural design work suitable for large tank PMD bubble filters according to the actual needs of my country's satellites
[0006] A surface tension tank bubble trap bubble filter is the first large-scale surface tension tank propellant management device bubble trap bubble filter in China. Its working method and structure are brand new. For reference, the development of the entire component was completed on the basis of DFH-3 storage tanks and very few foreign public documents.

Embodiment Construction
[0022] Such as figure 1 The Surface Tension Tank Bubble Trap Bubble Filter shown is used to manage propellant within the satellite propellant tank PMD Bubble Trap. The device includes the following components: box filter 1 , plate filter 2 and straight pipe 3 . The straight pipe 3 of the hollow structure between the box filter 1 and the plate filter 2 is welded by a pipe welding machine. By rationally designing the overall layout of the bubble filter in the bubble trap, the propellant inside the box filter is discharged from the bubble filter through a straight pipe, while the bubbles at the bottom of the plate filter are blocked from the bubble filter, so that the propellant in the bubble trap can be realized The propellant is managed to ensure that the gas stored in the bubble trap cannot be discharged from the storage tank, and it plays the role of managing and transporting the propellant.

Disclosed is a bubble filter for a bubble trap of a surface tension storage tank. The bubble filter is mounted in the bubble trap of a PMD (propellant management device) to filter a propellant in the bubble trap and prevent pressurized gas from flowing out of the storage tank. The bubble filter for the bubble trap comprises a box-type filter, a plate-type filter and a straight pipe, the box-type filter is located on the upper portion of the bubble filter so as to collect the propellant located at the top of the bubble filter, the plate-type filter is located on the lower portion of the bubble filter so as to collect the propellant at the bottom of the bubble filter, and the box-type filter and the plate-type filter are connected through the straight pipe which is of a hollow structure. The box-type filter and the plate-type filter work together to enable liquid inside the box-type filter to be discharged from the bubble filter through the straight pipe, so that the gas stored in the bubble trap is ensured not to be discharged outside the storage tank, and a function of propellant transmission is achieved.
Description
technical field [0001] The invention relates to a surface tension tank bubble trap bubble filter, which can filter the propellant in the bubble trap, prevent pressurized gas from flowing out of the storage tank, and is used for propellant management in 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). [0003] 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 prevent the...
