Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The utility model provides a flow dividing device for a xenon gas cylinder as Figures 1-4 shown, which includes a xenon gas cylinder body 1. A main pipeline 2 is installed at the upper end position of the xenon gas cylinder body 1. A connection cover 3 is installed at the lower end of the main pipeline 2 at the left side position. The connection cover 3 increases the sealing performance when installed with the main pipeline 2 through a sealing gasket 4 at the upper end position. A filter element 11 for filtering xenon gas is installed at the upper end position of the connection cover 3. The internal structure of the filter element 11 is composed of a pre-filter layer 12, a microporous layer 13, an activated carbon layer 14, and a terminal filter layer 15. A pressure gauge 5 for monitoring the pressure is installed at the upper end position of the main pipeline 2. A main pipe valve 9 for controlling the flow of xenon gas is provided at the upper right end of the main pipeline 2 at the upper position. A flow dividing valve body 7 is installed at the upper end position of the main pipeline 2. Branch pipelines 6 for dividing the gas source are installed at the four end face positions of the flow dividing valve body 7. The branch pipelines 6 discharge the divided gas source through a flow dividing gas source interface 10 at the upper end position. A branch valve 8 for controlling the flow of xenon gas is installed at the outer side position of the branch pipelines 6.

[0024] Connect the xenon gas cylinder body 1 to the main pipeline 2. A pressure gauge 5 is installed on the main pipeline 2 to monitor the pressure of the xenon gas. Open the main pipeline valve 9 on the main pipeline 2 to ensure that the xenon gas can flow smoothly into the shunt valve body 7. The shunt valve body 7 shunts the xenon gas into the branch pipeline 6. The branch valve 8 can be adjusted as needed to allow the xenon gas to flow out through the shunt gas source interface 10. Through such a workflow, the shunt device for xenon gas cylinders can achieve the shunting and control of xenon gas, meet the requirements for the flow rate and pressure of xenon gas in different scenarios, and ensure the stability and safety of the xenon gas system.

[0025] As Figure 3 and Figure 4 shown, when the xenon gas cylinder body 1 is installed with the main pipeline 2, the internal xenon gas flows into the internal position of the main pipeline 2. The filter element 11 filters the impurities in the xenon gas. When the connection cover 3 is disassembled, the filter element 11 can be cleaned or replaced. When the connection cover 3 is installed, the sealing gasket 4 is used to increase the sealing performance. The pre-filter layer 12 is located on the outermost layer of the filter element 11 to capture large particle impurities. After the pre-filter layer 12 completes filtration, it enters the microporous layer 13. The microporous layer 13 uses fiberglass material to capture smaller particle impurities. After the microporous layer 13 completes filtration, the xenon gas passes through the activated carbon layer 14. The activated carbon layer 14 adsorbs the odors in the xenon gas. The terminal filter layer 15 is the innermost layer of the filter element 11, and the terminal filter layer 15 filters fine particles. After the main pipeline valve 9 is opened, the xenon gas can flow into the internal position of the shunt valve body 7. The shunt valve body 7 shunts the xenon gas through four branch pipelines 6. After the branch valve 8 is opened, the shunted xenon gas is discharged through the shunt gas source interface 10.

[0026] The pre-filter layer 12 is located on the outer layer of the filter element 11 and is mainly used to capture large particle impurities and particulate matters to prevent them from entering the finer filter layers and protect the normal operation of the subsequent filter layers. The microporous layer 13 follows the pre-filter layer 12 and has a smaller pore diameter, which is used to capture medium-sized particles and impurities, improving the filtration efficiency and capture ability. The activated carbon layer 14 is located below the microporous layer 13 and is used to adsorb the odors, strange smells, and harmful gases in the xenon gas, improving the purity and cleanliness of the xenon gas. The terminal filter layer 15, as the innermost layer of the filter element 11, has extremely high filtration accuracy and capture efficiency and is used for filtering the finest particles and impurities to ensure the final purity of the xenon gas.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
