Description

Technical Field

[0001] The invention relates to the technical field of gas recovery, and in particular to a SF6 gas bottle pressing device. Background Art

[0002] At present, when performing gas recovery operations on GIS equipment, the traditional bottle pressing method can only compress gas on a single gas cylinder to recover the SF6 gas in the gas chamber. Every time a gas cylinder is filled, the operator must interrupt the current operation and replace it with a new gas cylinder to continue compressing gas, and repeat this process until the recovery is completed. However, this traditional method has several significant disadvantages:

[0003] 1. Significant reduction in operating efficiency: Since operations need to be frequently interrupted to replace gas cylinders, this not only interrupts the continuity of work, but also directly leads to a reduction in the overall gas recovery efficiency.

[0004] 2. Increased risk of environmental pollution: In the process of replacing gas cylinders, a small amount of gas leakage is inevitable. As the number of replacements accumulates, the total amount of leakage also increases. As a greenhouse gas, the environmental impact of SF6 gas cannot be ignored, and it may lead to increased pollution of the local environment.

[0005] Therefore, it has become a top priority to innovate and optimize existing technologies in order to seek more efficient and environmentally friendly gas recovery solutions.

[0006] The above information is presented as background information only to assist with understanding the present disclosure and no determination or admission is made as to whether any of the above may be used as prior art with respect to the present disclosure. Summary of the invention

[0043] Embodiment 1

[0044] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0045] Please refer to Figure 1-3 The embodiment of the present invention provides a SF6 gas cylinder pressing device, comprising at least two gas cylinders 1 and a gas filling pipeline 2; wherein,

[0046] The inflation pipeline 2 includes at least two pipeline connectors 21 and at least two connecting pipelines 22;

[0047] One connecting pipe 22 is connected between each two adjacent pipe connectors 21;

[0048] A connecting pipe 22 is connected between a pipe connector 21 connected to the air chamber 3 and the air chamber 3;

[0049] Each of the pipe connectors 21 is connected to a gas cylinder 1 .

[0050] It should be noted that the embodiment of the present invention has achieved a major breakthrough in SF6 gas recovery operations by ingeniously designing a gas charging pipeline 2 including at least two pipe connectors 21 and corresponding connecting pipes 22. Specifically, the design allows for the simultaneous compression of at least two gas cylinders 1. This improvement not only significantly reduces the frequency of gas cylinder 1 replacement, thereby greatly improving the overall efficiency of the operation, but also effectively reduces the potential risk of SF6 gas leakage by eliminating or reducing the number of gas cylinder replacements. This environmentally friendly design is highly consistent with the current urgent needs of green power grid development and has made positive contributions to reducing environmental pollution and promoting sustainable development.

[0051] Please refer again Figure 1In one implementation of this embodiment, the at least two pipe connectors 21 include a three-way pipe and a two-way pipe;

[0052] The two-way pipe is respectively connected to one of the gas cylinders 1 and the adjacent three-way pipe;

[0053] The three-way pipe is connected to one of the gas cylinders 1 , the adjacent two-way pipe and the gas chamber 3 respectively.

[0054] Specifically, the design of the two-way pipe is simple and efficient. One end of the two-way pipe is tightly connected to a gas cylinder 1, ensuring the stable transmission of gas; the other end is seamlessly connected to the adjacent three-way pipe, thus building a bridge for gas circulation.

[0055] The three-way pipe exhibits a more complex connection function. One end of it is also connected to a gas cylinder 1, ensuring that the gas cylinder can be smoothly connected to the entire gas recovery system; the other end is connected to the adjacent two-way pipe, further strengthening the connectivity of the system. More importantly, the third port of the three-way pipe is directly connected to the gas chamber 3. This design allows the SF6 gas recovered from the gas chamber 3 to flow smoothly into the connecting pipe, and then be compressed and stored in the gas cylinder.

[0056] In summary, by cleverly using the three-way pipe and the two-way pipe, this embodiment not only achieves efficient connection of the gas recovery system, but also ensures the stability and continuity of gas transmission. This design not only improves operating efficiency, but also effectively reduces the risk of gas leakage, providing a strong guarantee for the safe and environmentally friendly recovery of SF6 gas.

[0057] Please refer again Figure 2-3 In one implementation of this embodiment, the at least two pipe connectors 21 include at least two tees and one two-way pipe; wherein, Figure 2 The diagram shows two three-way pipes and one two-way pipe. Figure 3 The diagram shows three tees and one two-way pipe;

[0058] The two-way pipe is respectively connected to one of the gas cylinders 1 and an adjacent three-way pipe;

[0059] One of the three-way pipes is respectively connected to one of the gas cylinders 1, the adjacent two-way pipe and an adjacent three-way pipe;

[0060] One of the three-way pipes is respectively connected to one of the gas cylinders 1, an adjacent three-way pipe and the gas chamber 3;

[0061] The remaining three-way pipes are respectively connected to one of the gas cylinders 1 and two adjacent three-way pipes.

[0062] It should be noted that this design not only improves the connectivity and flexibility of the gas recovery system, but also enables the system to process more gas cylinders at the same time, further improving operational efficiency.

[0063] In one implementation of this embodiment, the connecting pipe 22 is a copper pipe.

[0064] It should be noted that copper tubes are widely used in gas transmission systems due to their excellent electrical conductivity, corrosion resistance and good mechanical strength. The copper tube is selected as the material of the connecting pipe 22 mainly based on the following considerations:

[0065] First, copper tubes have good sealing properties and can effectively prevent gas leakage during transmission, which is especially important for gases such as SF6 that require strict leakage control. Secondly, copper tubes have good corrosion resistance and can maintain the stability of their performance even in humid or corrosive environments, thereby extending the service life of the entire gas recovery system. In addition, copper tubes also have high mechanical strength and can withstand certain pressure and impact, ensuring safety during gas compression and transmission.

[0066] In summary, the selection of copper pipe as the material of the connecting pipe 22 not only improves the overall performance of the gas recovery system, but also ensures its reliability and stability in various complex environments. This design choice reflects the rigorous material selection and pursuit of system performance of the present invention.

[0067] In one implementation of this embodiment, the structural design of the bottle pressing device is further optimized, and the importance of sealing and pressure bearing capacity is particularly emphasized. Specifically, in order to ensure that the connection between the pipeline connector 21 and the gas cylinder 1 is both tight and reliable, prevent gas leakage and improve operating efficiency, a metal seal is added between the two.

[0068] The use of metal seals is based on a deep understanding and strict control of the sealing performance of the bottle pressing device. During the bottle pressing process, the gas needs to be compressed and converted into liquid under a higher pressure. If the matching degree between the pipe connector 21 and the gas cylinder 1 is not high or the sealing is not tight, it will cause gas leakage, which will affect the efficiency of the entire operation process. Therefore, the metal sealing form is adopted, through precise processing and assembly, to ensure that the pipe connector 21 can fully match the gas cylinder 1 and form a good sealing effect, thereby effectively avoiding the problem of gas leakage.

[0069] In addition, in view of the high pressure environment required for gas to be converted into liquid during the bottle pressing process, pipes of special thickness are specially used. These pipes not only have sufficient pressure bearing capacity to maintain structural stability and safety under high pressure, but are also carefully designed and selected to ensure that they will not break or deform due to excessive pressure during use.

[0070] In summary, by adding metal seals and using pipes of specially made thickness, this embodiment has achieved remarkable results in improving the sealing and pressure bearing capacity of the bottle pressing device. This design optimization not only enhances the overall reliability and safety of the device, but also provides a more solid guarantee for the efficient and environmentally friendly recovery of SF6 gas.

[0071] Although the terms such as gas cylinder and gas charging pipeline are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0072] An SF6 gas cylinder pressing device provided in an embodiment of the present invention is designed to include a charging pipeline including at least two pipe connectors and at least two connecting pipes, so that when performing SF6 gas recovery operations, at least two gas cylinders can be pressed at the same time, thereby reducing the number of gas cylinder replacements, improving operating efficiency, and reducing SF6 gas leakage, reducing environmental pollution risks, and meeting the development needs of green power grids.

[0073] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
