[0032] Please see Figure 2 and Figure 6 The ultra-high pressure gas filling assembly 5 also includes a cooling pump 51 for cooling the gas. The cooling pump 51 is mounted on the lower part of the inner frame 3. One end of the cooling pump 51 is connected to the housing 471 through a pipe, and the other end is connected to gas cylinders A56, B57 and C58 through a pipe. Solenoid valves are installed on the pipes. This scheme forms a gas recovery system.

By gradually increasing the pressure of the gas chamber, the pressure is increased to the standard value, which is convenient for subsequent experiments.

[0034] The working principle of this utility model patent for a visual online pressure calibration ultra-high pressure gas filling device for a diamond anvil chamber is as follows: First, the diamond chamber is opened by a servo motor 41, allowing 250MPa high-pressure gas to enter the sample chamber inside the housing 471. Then, the diamond chamber is closed, and pressure is applied to seal the high-pressure gas within it. The gas in the gas cylinder is pressurized and delivered to the sample chamber by a primary booster pump 53 and a secondary booster pump 54. While pressurizing the diamond sample chamber, a ruby ​​pressure calibration system 48, in conjunction with the sapphire window sealing area 474 of the flange, reads and calibrates the pressure inside the diamond chamber to determine the pressure of the diamond chamber. After successful sealing, the 250MPa high-pressure gas is depressurized, and the sample is removed from the diamond pressure chamber. This reduces the probability of sealing failure within the diamond pressure chamber and improves experimental efficiency. During depressurization, the gas is cooled by the cooling pump 51 and then flows back to the corresponding gas cylinder for storage. The recovered gas can be reused. The three-way gas switching and recovery scheme provides more options for gas pressure transmission media, facilitates the switching of commonly used gases, and has a cleaning function. There is no need to worry about the impact of multiple gas residues on experimental data. The gas recovery system greatly improves gas economy and can reduce experimental costs.
