[0002] Sulfur hexafluoride (SF6) is a non-toxic, non-flammable insulating gas with excellent insulation properties. Its dielectric strength is significantly higher than that of traditional insulating gases, and it exhibits excellent arc-extinguishing properties. Therefore, it is widely used in equipment requiring sealed insulation. The AMAT 1500H high-energy implanter features an accelerator module capable of providing a maximum DC voltage of 750 kV. To ensure insulation performance, the sealed chamber of the high-energy implanter is filled with SF6, an arc-extinguishing medium, at a certain pressure.

[0003] In the related art, the SF6 filling pipeline joints are two threaded joints, which are connected by internal and external threads. This threaded connection method can withstand the higher pressure output by the SF6 cylinder.

[0004] However, after the SF6-filled pipe joints have been disassembled and assembled many times, the threads at the joints will be worn to a certain extent, causing the pipe joints to slip, resulting in SF6 gas leakage and affecting the air tightness of the pipeline. Utility Model Content

[0005] Based on this, it is necessary to provide a high-pressure filling pipeline joint and equipment to address the problem that the existing high-pressure filling pipeline joint is prone to slipping and affects the air tightness of the pipeline.

[0009] When the first quick-release connector and the second quick-release connector are in a connected state, the first connection surface and the second connection surface are tightly fitted.

[0010] In one embodiment, the other end of the first quick connector is connected to a sulfur hexafluoride (SF6) cylinder via a high-pressure filling pipeline, and the sulfur hexafluoride (SF6) cylinder is used to fill SF6 gas into the high-pressure filling pipeline.

[0011] In one embodiment, the other end of the second quick connector is connected to a sealed cabin of a high-energy injection machine via a high-pressure filling pipeline for injecting SF6 gas into the sealed cabin.

[0012] In one embodiment, the high-pressure filling pipeline connector further includes a purge valve, which is located on the high-pressure filling pipeline between the second quick-connect connector and the sealed cabin of the high-energy injection machine, or on the other end of the second quick-connect connector, wherein:

[0013] When the Purge valve is in an open state, it is used to evacuate the gas remaining in the high-pressure filling pipeline.

[0014] In one embodiment, the Purge valve is a manual valve.

[0015] In one embodiment, the sealing mechanism is a detachable O-ring.

[0016] In one embodiment, at least one buckle is further provided on one end of the first quick-release connector and / or one end of the second quick-release connector, wherein:

One end of the first quick-release connector and one end of the second quick-release connector constitute the two connecting ends of the high-pressure filling pipeline connector. The other end of the first quick-release connector and the other end of the second quick-release connector are respectively connected to the high-pressure filling pipeline. This makes the high-pressure filling pipeline connector easy to disassemble and assemble, and will not cause wear to the connector part after multiple disassembly and assembly, thereby ensuring the airtightness of the connection.

[0033] For example, Figure 1 This is a schematic diagram of an application scenario of a high-pressure filling pipe joint provided in an embodiment of the present application. Figure 1 The internal structure of the high-energy injection machine is shown in FIG. A filling inlet is provided in a sealed compartment (i.e., the sealed space within the machine) of the high-energy injection machine. This filling inlet is connected to a sulfur hexafluoride (SF6) cylinder 20 via a pipeline. The pipeline is provided with at least one connector, which is a high-pressure filling pipeline connector 10.

[0034] For example, the AMAT 1500H high energy injection machine has an accelerator module that can provide a maximum DC voltage of 750KV. In order to ensure the insulation performance, it is necessary to fill the sealed cabin of the high energy injection machine with a certain pressure of arc extinguishing medium SF6. Therefore, you can refer to Figure 1 As shown, the gas in the SF6 cylinder is filled into the sealed cabin of the high-energy injection machine through the pipeline connected by the high-pressure filling pipeline connector 10, thereby achieving the arc extinguishing effect.

[0035] It should be noted that this embodiment only illustrates one application scenario of a high-pressure filling pipe connector and does not limit its use in other scenarios. For example, the high-pressure filling pipe connector in this embodiment can also be used in equipment requiring high-pressure sealed transmission or other products equipped with high-pressure pipelines.

[0036] For example, Figure 2 This is a schematic diagram of the structure of the high-pressure filling pipe joint provided in the embodiment of the present application, as shown in FIG. Figure 2 As shown, the high-pressure filling pipeline connector 10 includes: a first quick-release connector 11, a second quick-release connector 12, and a sealing mechanism. One end of the first quick-release connector 11 and one end of the second quick-release connector 12 constitute the two connecting ends of the high-pressure filling pipeline connector 10, and the other end of the first quick-release connector 11 and the other end of the second quick-release connector 12 are respectively connected to the high-pressure filling pipeline. The sealing mechanism is located outside the connection area of ​​the two connecting ends, wherein: the sealing mechanism is used to fix the relative position of the two connecting ends and seal the connection gap between the two connecting ends.

[0037] In this embodiment, the connection ends of the first quick-release connector and the second quick-release connector do not adopt the form of internal and external threads, so that the threads will not wear out or slip after multiple disassembly and assembly, effectively extending the service life of the high-pressure filling pipeline connector, and is suitable for pipelines that need frequent replacement.

[0038] It should be noted that ordinary quick-release connectors cannot withstand higher gas pressures (cylinder pressure of SF6 cylinders), while the high-pressure filling pipe connector in the embodiment of the present application can withstand a pressure of 10 bar. While having the function of quick disassembly and assembly, it can also ensure the air tightness of the pipeline.

[0039] This embodiment includes a first quick-release connector, a second quick-release connector, and a sealing mechanism. One end of the first quick-release connector and one end of the second quick-release connector constitute the two connecting ends of the high-pressure filling pipeline connector. The other ends of the first quick-release connector and the other ends of the second quick-release connector are respectively connected to the high-pressure filling pipeline. This makes the high-pressure filling pipeline connector easy to assemble and disassemble, and does not cause wear to the connector parts after repeated assembling and disassembling, thereby ensuring the airtightness of the connection. By locating the sealing mechanism outside the connection area of ​​the two connecting ends, wherein: the sealing mechanism is used to fix the relative position of the two connecting ends and seal the connection gap between the two connecting ends, the modified high-pressure filling pipeline connector can thus have good airtightness and withstand the high output pressure of the SF6 cylinder.

[0040] For example, Figure 4 Schematic diagram of the sealing mechanism in the embodiment of the present application. Figure 4 As shown, the sealing mechanism includes two semicircular rings that can be spliced ​​together. When the two semicircular rings are combined together, they can tighten the connecting ends of the first quick-release connector and the second quick-release connector.

[0041] For example, except Figure 4 In addition to the sealing mechanism, the sealing mechanism can also be a detachable O-ring. Providing a sealing ring in the connection area between the first and second quick-connect connectors not only increases the connection strength between the first and second quick-connect connectors, but also significantly improves the sealing of the connectors, preventing the high-pressure gas in the high-pressure filling line from leaking.

[0042] For example, Figure 3 A cross-sectional schematic diagram of a high-pressure filling pipe joint provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the end surface of one end of the first quick connector 11 constitutes a first connecting surface, and the end surface of one end of the second quick connector 12 constitutes a second connecting surface, wherein: when the first quick connector and the second quick connector are in a connected state, the first connecting surface and the second connecting surface are tightly fitted.

[0043] For example, combined Figure 1 and Figure 3 As can be seen, the other end of the first quick-connect connector 11 is connected to a sulfur hexafluoride (SF6) cylinder 20 via a high-pressure filling line. The sulfur hexafluoride (SF6) cylinder 20 is used to fill the high-pressure filling line with SF6 gas. The other end of the second quick-connect connector 12 is connected to the sealed chamber of the high-energy implantation equipment via a high-pressure filling line, used to inject SF6 gas into the sealed chamber.

[0044] In an optional embodiment, the high-pressure filling pipeline connector includes: a first quick-release connector 11, a second quick-release connector 12, a sealing mechanism, and a purge valve, wherein one end of the first quick-release connector 11 and one end of the second quick-release connector 12 constitute the two connecting ends of the high-pressure filling pipeline connector 10, and the other end of the first quick-release connector 11 and the other end of the second quick-release connector 12 are respectively connected to the high-pressure filling pipeline, and the sealing mechanism is located outside the connection area of ​​the two connecting ends, wherein: the sealing mechanism is used to fix the relative position of the two connecting ends and seal the connection gap between the two connecting ends. The purge valve is located on the high-pressure filling pipeline between the second quick-release connector and the sealed cabin of the high-energy injection machine, or on the other end of the second quick-release connector, wherein: when the purge valve is in the open state, it is used to evacuate the residual gas in the high-pressure filling pipeline.

[0045] Exemplarily, the purge valve is a manual valve. When the purge valve is opened, the air in the pipeline is evacuated. After the air is completely evacuated, the purge valve is tightened to fill the pipeline with SF6 gas.

[0046] In this embodiment, by using a purge valve, exhaust and cleaning functions can be achieved to ensure the purity of the gas in the pipeline. In some special cases, the gas pressure in the pipeline can also be adjusted (for example, when the pressure is too high, the pressure can be reduced).

[0047] In another optional embodiment, combined with Figure 3As shown, the high-pressure filling pipeline connector includes: a first quick-release connector 11, a second quick-release connector 12, and a sealing mechanism. One end of the first quick-release connector 11 and one end of the second quick-release connector 12 constitute the two connecting ends of the high-pressure filling pipeline connector 10. The other ends of the first quick-release connector 11 and the other ends of the second quick-release connector 12 are respectively connected to the high-pressure filling pipeline. The sealing mechanism is located outside the connection area of ​​the two connecting ends, wherein: the sealing mechanism is used to fix the relative position of the two connecting ends and seal the connection gap between the two connecting ends. In addition, at least one clip is provided on one end of the first quick-release connector and / or one end of the second quick-release connector, wherein: the clip has at least two states: when the clip is in the first state, the two connecting ends of the high-pressure filling pipeline connector are tightly connected; when the clip is in the second state, the two connecting ends of the high-pressure filling pipeline connector are separated.

[0048] In this embodiment, at least one buckle is provided on one end of the first quick-release connector and / or one end of the second quick-release connector to fasten the flanges of the two connectors, thereby ensuring that the connectors can be well docked.

[0049] It should be noted that, in addition to the snap-fit ​​form, other auxiliary fixing and positioning mechanisms may also be provided, such as positioning columns and positioning holes.

[0050] It should be noted that this embodiment can also be equipped with a purge valve. Specifically, at least one purge valve can be installed in the high-pressure filling line between the second quick-connect connector and the sealed chamber of the high-energy implantation system, or at the other end of the second quick-connect connector. The purge valve can perform venting and purging functions to ensure the purity of the gas in the line. In some special cases, it can also regulate the air pressure in the line (for example, to reduce the pressure when it is too high).

[0051] Exemplarily, the first quick-release connector and the second quick-release connector are made of stainless steel.

[0052] In this embodiment, the first quick-release connector and the second quick-release connector made of stainless steel can have better strength, avoid rust and corrosion, and extend the service life of the connector.

[0053] In addition, an embodiment of the present application further provides a high-pressure filling device, comprising: Figures 1 to 4 The high-pressure filling pipeline connector according to any one of the above is used to connect a high-pressure filling pipeline.

[0054] In this embodiment, gas filling is performed using a pipeline including a high-pressure filling pipe connector. This makes the connector easy to assemble and disassemble, and prevents wear to the connector even after repeated assembly and disassembly, ensuring airtightness at the connection. By providing sealing mechanisms around the connection area at both ends, the modified high-pressure filling pipe connector achieves excellent airtightness, capable of withstanding the higher output pressure of SF6 cylinders.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
