[0002] The system of mechanical pump driven fluid circuit includes mechanical pump, liquid reservoir, heat exchanger, preheater, evaporator, condenser and connecting pipes, etc. The liquid reservoir plays the role of controlling the system temperature, adjusting the fluid distribution between the main circuit and the liquid reservoir, and managing gas-liquid fluid under microgravity conditions in the mechanical pump driven two-phase fluid circuit system. The working fluid is saturated in the liquid reservoir and evaporator, and the saturated temperature and pressure inside these two components are basically equal.

[0057] When the refrigerant flows downward along the liquid inlet hopper 4, the impact force of the refrigerant pushes the fan blade 51 to rotate, and the fan blade 51 drives the polygonal rod 5 to rotate, and the polygonal rod 5 drives the scraper 52 to rotate along the inner wall of the filter cylinder 44, so as to clean the impurities on the inner wall of the filter cylinder 44, prevent the filter holes on the side of the filter cylinder 44 from being blocked, and enable the filter cylinder 44 to continuously filter the refrigerant;

[0058] The polygonal rod 5 rotates while driving the rotating seat 6 to rotate, the rotating seat 6 drives the circular shaft 61 to rotate, the circular shaft 61 rotates while driving the circular plate 63 to rotate, the circular plate 63 drives the multiple lower extrusion hemispheres 64 to rotate, when the lower extrusion hemisphere 64 moves close to the upper extrusion hemisphere 71, the lower extrusion hemisphere 64 abuts against the upper extrusion hemisphere 71, and at the same time pushes the upper extrusion hemisphere 71 to move upward, the upper extrusion hemisphere 71 drives the annular frame 74 to move upward through the lifting ring 7 and the L-shaped frame 73, the lifting ring 7 squeezes the reset spring 72, and the annular frame 74 drives the filter screen 75 to move upward;

[0059] When the lower extrusion hemisphere 64 is separated from the upper extrusion hemisphere 71, the return spring 72 applies elastic force to the lifting ring 7, so that the lifting ring 7 moves downward, thereby moving the filter screen 75 downward, and so on and so forth, so that the filter screen 75 can shake up and down, preventing impurities filtered out of the filter screen 75 from causing clogging of the filter screen 75, so that the filter screen 75 can continue to filter the refrigerant.

[0060] When it is necessary to process the impurities in a filter assembly, by turning the adjusting knob 38, the adjusting knob 38 drives the driving bevel gear 36 to rotate through the rotating shaft 37, so that the driven bevel gear 31 drives the first adjusting ball 32 and the second adjusting ball 34 to rotate 180 degrees through the connecting shaft 3, so that one end of the first L-shaped connecting groove 33 is connected with another circular groove 21, and the second L-shaped connecting groove 35 is connected with another circular filter cavity 23, so that the refrigerant flows into the other circular filter cavity 23 along the first L-shaped connecting groove 33, and the refrigerant is filtered through another filter assembly;

[0061] At this time, the two-way transmission screw 81 is rotated by rotating the adjusting sleeve 82, so that the two push plates 83 on the two-way transmission screw 81 are close to each other, and the push plates 83 drive the positioning rod 84 to come out from the slot of the positioning plate 27. At this time, the concave limit cover 8 can be moved upward, so that the concave limit cover 8 releases the limit lock on the filter assembly;

[0062] At this time, the two concave ear plates 43 are pulled upward, and the concave ear plates 43 drive the coarse filtering mechanism, the fine filtering mechanism and the auxiliary cleaning mechanism to move out of the filter valve body 2, so as to facilitate the cleaning of impurities filtered out by the coarse filtering mechanism and the fine filtering mechanism, and the equipment does not need to be stopped during the cleaning process;

[0063] The two circular filter chambers 23 in the filter valve body 2 are used alternately, and the filter assembly in the circular filter chamber 23 is easy and convenient to disassemble, which greatly improves the work efficiency;

[0064] During installation, first install the filter assembly in the circular filter cavity 23, and then clamp the concave limiting cover 8 in the rectangular groove, so that the concave limiting cover 8 abuts against the two concave ear plates 43 at the upper end of the filter assembly, and at the same time, the circular rod at the upper end of the polygonal rod 5 is plugged into the concave limiting cover 8, and then by rotating the adjusting sleeve 82 in the opposite direction, the two push plates 83 on the two-way transmission screw 81 are moved away from each other, and the push plate 83 drives the positioning plug 84 to be inserted into the slot of the positioning plate 27, so that the concave limiting cover 8 limits and locks the filter assembly, which makes the disassembly and installation of the filter assembly simple and convenient, and greatly improves the work efficiency.
