[0032] like Figure 1-3As shown, the present application provides an atmosphere regulating device for manned space scientific experiments, including a mounting bracket 1, a main gas source cylinder 2, a regulating gas source cylinder 3, a first control module and a second control module, wherein: the mounting bracket 1 is a semi-closed box structure, and the front end of the side wall of the mounting bracket 1 is provided with a main gas source output connector 4 and a regulating gas source output connector 5; the main gas source cylinder 2 is arranged on one side of the top of the mounting bracket 1 through a cylinder holder, and the regulating gas source cylinder 3 is arranged on the other side of the top of the mounting bracket 1 through a cylinder holder; a main gas source pipeline and a regulating gas source pipeline are arranged inside the lower part of the mounting bracket 1; one end of the main gas source pipeline is connected to the bottle mouth valve 9 of the main gas source cylinder 2, and the other end is connected to the main gas source output connector 4; one end of the regulating gas source pipeline is connected to the bottle mouth valve 9 of the regulating gas source cylinder 3, and the other end is connected to the regulating gas source output connector 5; the first control module is arranged on the main gas source pipeline, and the second control module is arranged on the regulating gas source pipeline.
[0033] Specifically, the atmosphere conditioning device for manned space science experiments provided in the embodiments of the present application is primarily used to precisely supply multiple test gases to a test vessel. A main gas source cylinder 2 and a regulating gas source cylinder 3 are used to store and output two high-pressure gases, with a maximum operating pressure of 30 MPa. The mounting bracket 1 is a semi-enclosed box structure, with the top used to securely mount the two gas cylinders. The interior of the mounting bracket is used to arrange gas source output pipelines, including two sets of output pipelines: a main gas source pipeline and a regulating gas source pipeline. The main gas source pipeline is connected to the main gas source cylinder 2 and outputs the gas inside the main gas source cylinder 2 to the rear-end test vessel via a main gas source output connector 4. The regulating gas source pipeline is connected to the regulating gas source cylinder 3 and outputs the gas inside the regulating gas source cylinder 3 to the rear-end test vessel via a regulating gas source output connector 5. A first control module and a second control module are respectively disposed on the main gas source pipeline and the regulating gas source pipeline, and are used to reduce the pressure of the high-pressure gas output from the gas cylinders to the required accuracy and ensure the safety of upstream and downstream gas storage and supply. Furthermore, the control module can control the output gas flow rate to achieve precise gas supply to the rear-end test vessel.
[0034] Furthermore, the first control module includes a first high-pressure hose 71, a first pressure reducing valve 72, a first pressure sensor 73, a first safety valve 74, and a first flow controller 75, which are arranged on the main gas source pipeline. The first high-pressure hose 71 is connected to the bottle mouth valve 9 of the main gas source cylinder 2, the first pressure reducing valve 72, and the first pressure sensor 73 via a three-way connector; the first safety valve 74 is integrated downstream of the first pressure reducing valve 72 and connected to the first flow controller 75; and the first flow controller 75 is arranged between the first pressure reducing valve 72 and the main gas source output connector 4. The first high-pressure hose 71 is arranged between the main gas source pipeline and the main gas source cylinder 2 and is used to output the gas in the main gas source cylinder 2. The high-pressure hose is easy to install and remove; the first pressure reducing valve 72 is used to reduce the pressure of the gas output from the main gas source cylinder 2; the first pressure sensor 73 is used to monitor the pressure inside the main gas source pipeline; the first safety valve 74 is used to protect the main gas source pipeline; and the first flow controller 75 is used to control the flow rate of gas output from the main gas source output connector 4.
[0035] Furthermore, the second control module includes a second high-pressure hose 81, a second pressure reducing valve 82, a second pressure sensor 83, a second safety valve 84, and a second flow controller 85, which are arranged on the regulating gas source pipeline. The second high-pressure hose 81 is respectively connected to the bottle mouth valve 9 of the regulating gas source cylinder 3, the second pressure reducing valve 82, and the second pressure sensor 83 via a three-way connector; the second safety valve 84 is integrated downstream of the second pressure reducing valve 82 and connected to the second flow controller 85; and the second flow controller 85 is arranged between the second pressure reducing valve 82 and the regulating gas source output connector 5. The second high-pressure hose 81 is arranged between the regulating gas source pipeline and the regulating gas source cylinder 3 to regulate the output of gas from the gas source cylinder 3. The high-pressure hose facilitates installation and removal; the second pressure reducing valve 82 is used to reduce the pressure of the gas output from the regulating gas source cylinder 3; the second pressure sensor 83 is used to monitor the pressure inside the regulating gas source pipeline; the second safety valve 84 is used to protect the regulating gas source pipeline; and the second flow controller 85 is used to control the flow rate of gas output from the regulating gas source output connector 5.
[0036] Further, such as Figure 4-5 As shown, the gas cylinder holder includes a left holder 61 and a right holder 62. The left holder 61 and the right holder 62 are multi-segment belt-like structures when opened, and a ring-shaped buckle structure when closed. The gas cylinder holder adopts a principle similar to a belt. When opened, it is a multi-segment belt-like structure, and when closed, it is a ring-shaped buckle structure. It includes a left holder 61 and a right holder 62, which are respectively arranged on the left and right sides of the gas cylinder to fix the gas cylinder on the mounting bracket 1. Before transportation and launch, the operator can close it manually by clamping the limit plates on both sides of the gas source cylinder body into the left holder 61 and the right holder 62; in microgravity, the astronaut can open it manually to replace the high-pressure gas cylinder.
[0037] Furthermore, both the main gas source cylinder 2 and the regulating gas source cylinder 3 are composite gas cylinders with short necks, and multiple sets of spacers are evenly wrapped around each side of the cylinder body. Both the main gas source cylinder 2 and the regulating gas source cylinder 3 are composite gas cylinders with an aluminum alloy lining and wrapped around a carbon fiber-wrapped structure. A portion of the neck seal extends into the cylinder, shortening the neck structure. Three sets of aluminum alloy spacers are preferably evenly wrapped around each side of the cylinder body, cooperating with the cylinder holder to limit axial movement of the cylinders and secure them in place.
[0038] Further, such as Figure 6 As shown, the bottle-mouth valve 9 of the main gas source cylinder 2 and the bottle-mouth valve 9 of the regulating gas source cylinder 3 are both equipped with a manual switch, a pointer pressure gauge, and a quick disconnect fixed end. When the main gas source cylinder 2 or the regulating gas source cylinder 3 needs to be replaced, the astronaut manually closes the valve, observes the pointer pressure gauge until the pressure in the chamber of the quick disconnect fixed end drops to a certain level, and then manually disconnects the first high-pressure hose 71 or the second high-pressure hose 81.
[0039] Furthermore, a plurality of fixing lugs are evenly distributed around the bottom of the mounting bracket 1. Preferably, 12 fixing lugs are arranged around the bottom of the mounting bracket 1 for assembly and docking with other test devices.
[0040] Furthermore, the main gas source output connector 4 and the regulating gas source output connector 5 are connected to the rear test container via a quick-disconnect low-pressure hose. The output connector uses a quick-disconnect low-pressure hose to connect to the rear test container, allowing for direct disassembly and removal of the entire unit after the test is completed.
[0041] Furthermore, the output pressure of the first pressure reducing valve 72 and the second pressure reducing valve 82 is 0.3±0.02 MPa. Observing the first pressure sensor 73 and the second pressure sensor 83, the first pressure reducing valve 72 and the second pressure reducing valve 82 respectively control the pressure inside the main gas source pipeline and the regulating gas source pipeline.
[0042] Furthermore, the output flow rate of the main gas source output connector 4 is 0-2 SLPM, and the output flow rate of the regulating gas source output connector 5 is 0-5 SLPM. According to the actual output conditions, the gas output flow rates of the main gas source output connector 4 and the regulating gas source output connector 5 are controlled by the first flow controller 75 and the second flow controller 85 respectively.
[0043] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
