[0008] As a further technical solution, the first connector includes a first pipeline fixedly connected to the gas storage tank. The first pipeline is provided with a first abutting rod located on the first pipeline and at the center of the first pipeline. The first abutting rod has a first sealing end and also includes a first sliding sleeve that is slidably disposed in the first pipeline. After the first sliding sleeve slides in the first pipeline, the first sealing end and the inner wall of the first sliding sleeve may abut or not abut. After the first sealing end abuts with the inner wall of the first sliding sleeve, it is used to seal the first sliding sleeve.
[0009] As a further technical solution, the first abutting rod has a first abutting end, and the second connector includes a second pipe that communicates with the first flow channel. The second pipe is located on the first end, and the second abutting rod is slidably disposed inside the second pipe. The second abutting rod has a second abutting end and a second sealing end.

[0018] This invention mainly includes a gas storage tank, a gas outlet pipe, a first connector, a second connector, and a gas outlet nozzle. The gas storage tank is a sealed container with an internal storage cavity specifically designed for storing sulfuryl fluoride gas. It effectively withstands gas pressure while preventing gas leakage, ensuring the safety and durability of the device. One end of the gas outlet pipe is connected to the first connector on the gas storage tank via the second connector. The first and second connectors are respectively designed with a first flow channel and a second flow channel. When connected, the channels align and connect, allowing the sulfuryl fluoride gas to smoothly pass from the storage cavity through the first and second flow channels into the gas outlet pipe. A gas outlet nozzle is installed at the end of the gas outlet pipe furthest from the second connector. The nozzle's nozzle orifice is designed with small spray holes, enabling the sulfuryl fluoride gas to be sprayed out in a mist form, thereby achieving uniform gas distribution and precise metering control. In actual use, by connecting the second connector to the first connector, the gas outlet pipe can be quickly and securely installed on the gas storage tank. At this time, the first and second flow channels are connected, and the gas can be smoothly output from the storage cavity. After use or when maintenance is required, the second connector can be quickly separated from the first connector, greatly reducing the space occupied by the device and facilitating its storage. This detachable design not only improves the flexibility and practicality of the device but also reduces maintenance costs, effectively solving many inconveniences caused by the non-detachable nature of traditional devices. It provides a more efficient and convenient solution for the metering and use of sulfuryl fluoride gas. Attached Figure Description

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] Example
[0026] like Figures 1-3 As shown, the sulfuryl fluoride gas metering and control device includes a gas storage tank 1, which has a storage cavity 2 for storing sulfuryl fluoride gas. It also includes an outlet pipe 3 installed on the gas storage tank 1, with a second connector 4 on the outlet pipe 3. The gas storage tank 1 has a first connector 5. The first connector 5 and the second connector 4 each have a first flow channel 6 and a second flow channel 7, respectively, and both the first flow channel 6 and the second flow channel 7 are connected to the storage cavity 2. After the first connector 5 and the second connector 4 are connected, they are used to open the first flow channel 6 and the second flow channel 7. An outlet nozzle 8 is located on the side of the outlet pipe 3 away from the second connector 4, and the outlet nozzle 8 is connected to the second flow channel 7.
[0027] This embodiment mainly includes a gas storage tank 1, an outlet pipe 3, a first connector 5, a second connector 4, and an outlet nozzle 8. The gas storage tank 1 is a sealed container with an internal storage cavity 2 specifically designed for storing sulfuryl fluoride gas. It effectively withstands gas pressure while preventing gas leakage, ensuring the safety and durability of the device. The outlet pipe 3 is made of corrosion-resistant polytetrafluoroethylene (PTFE), and one end is connected to the first connector 5 on the gas storage tank 1 via the second connector 4. The first connector 5 and the second connector 4 are respectively designed with a first flow channel 6 and a second flow channel 7. When connected, the channels are aligned and interconnected, allowing the sulfuryl fluoride gas to smoothly enter the outlet pipe 3 from the storage cavity 2 through the first flow channel 6 and the second flow channel 7. An outlet nozzle 8 is installed at the end of the outlet pipe 3 furthest from the second connector 4. The nozzle's nozzle orifice is designed with small spray holes, enabling the sulfuryl fluoride gas to be sprayed out in a mist form, thereby achieving uniform gas distribution and precise metering control. In practical use, by connecting the second connector 4 to the first connector 5, the outlet pipe 3 can be quickly and securely installed on the gas storage tank 1. At this time, the first flow channel 6 and the second flow channel 7 are connected, and the gas can be smoothly output from the storage cavity 2. After use or when maintenance is required, the second connector 4 and the first connector 5 can be quickly separated, greatly reducing the space occupied by the device and facilitating its storage. This detachable design not only improves the flexibility and practicality of the device but also reduces maintenance costs, effectively solving many inconveniences caused by the non-detachable nature of traditional devices, and providing a more efficient and convenient solution for the metering and use of sulfuryl fluoride gas.
[0028] Furthermore, the air outlet pipe 3 is L-shaped, and the air outlet pipe 3 has a first end 9, with the second connector 4 located on the first end 9.
[0029] Furthermore, the air outlet pipe 3 has a second end 10, on which a gooseneck pipe is provided, and the air outlet nozzle 8 is connected to the second end 10 through the gooseneck pipe.
[0030] In this embodiment, the exhaust pipe 3 is L-shaped and has a first end 9 and a second end 10. The first end 9 is provided with a second connector 4 for connecting to the first connector 5 on the gas storage tank 1. The second end 10 is provided with a gooseneck tube, and the exhaust nozzle 8 is connected to the second end 10 through the gooseneck tube. The flexibility of the gooseneck tube allows the exhaust nozzle 8 to flexibly adjust its direction to adapt to different spraying needs and working scenarios.
[0031] Furthermore, the first connector 5 includes a first pipeline 11 fixedly connected to the gas storage tank 1. The first pipeline 11 is provided with a first abutting rod 12 located on the first pipeline 11 and at the center of the first pipeline 11. The first abutting rod 12 has a first sealing end 13 and also includes a first sliding sleeve 14 that is slidably disposed in the first pipeline 11. After the first sliding sleeve 14 slides in the first pipeline 11, the first sealing end 13 and the inner wall of the first sliding sleeve 14 may abut or not abut. After the first sealing end 13 and the inner wall of the first sliding sleeve 14 abut, it is used to seal the first sliding sleeve 14.
[0032] In this embodiment, the first connector 5 includes a first pipeline 11 fixedly connected to the gas storage tank 1. A first abutment rod 12 is provided at the center of the first pipeline 11, which extends axially along the pipeline and forms a first sealing end 13 at its end. The shape of the first sealing end 13 matches the inner wall of the first sliding sleeve 14, allowing for a tight fit.
[0033] The first pipe 11 is also equipped with a first sliding sleeve 14, which can slide freely along the axial direction of the first pipe 11. When the first sliding sleeve 14 slides to the position where it contacts the first sealing end 13, the first sealing end 13 will tightly abut against the inner wall of the first sliding sleeve 14, thereby achieving a seal and preventing gas from passing through. When the first sliding sleeve 14 slides to the position where it separates from the first sealing end 13, the first sealing end 13 is no longer in contact with the inner wall of the sliding sleeve, and gas can flow through the first pipe 11. This design allows the first connector 5 to achieve rapid on / off control through the sliding action of the first sliding sleeve 14 during connection. When it is necessary to open the gas flow, the first sliding sleeve 14 is slid to the position where it separates from the first sealing end 13; when it is necessary to close the gas flow, the first sliding sleeve 14 is slid to the position where it abuts against the first sealing end 13, thereby achieving a seal. This structure is not only simple to operate, but also has reliable sealing performance, which can effectively prevent gas leakage and ensure the safety and accuracy of the sulfuryl fluoride gas metering and control device.
[0034] Furthermore, the first abutting rod 12 has a first abutting end 15, and the second connector 4 includes a second pipe 16 communicating with the first flow channel 6. The second pipe 16 is located on the first end 9, and a second abutting rod 17 is slidably disposed inside the second pipe 16. The second abutting rod 17 has a second abutting end 18 and a second sealing end 19. After the second abutting rod 17 slides inside the second pipe 16, the second sealing end 19 abuts or does not abut against the inner wall of the second pipe 16. After the second sealing end 19 abuts against the inner wall of the second pipe 16, it is used to seal the second pipe 16.
[0035] The second pipe 16 has a plug end 20, which is used to slide into the first pipe 11. After the plug end 20 slides in the first pipe 11, the first abutting end 15 and the second abutting end 18 abut against and push the first sliding sleeve 14 and the second abutting rod 17 to move in opposite directions.
[0036] It also includes a sliding member 21 that is slidably disposed on the outer wall of the first pipe 11. The side wall of the first pipe 11 has a through hole 22, and the side wall of the second pipe 16 has a locking groove 23. An abutment ball 24 is movably disposed in the through hole 22. After the sliding member 21 slides on the first pipe 11, it is used to push or not push the abutment ball 24 into the locking groove 23. After the abutment ball 24 slides into the locking groove 23, it is used to fix the first pipe 11 and the second pipe 16.
[0037] In this embodiment, the first abutting rod 12 has a first abutting end 15, and the second connector 4 includes a second pipe 16 communicating with the first flow channel 6, which is located on the first end 9 of the gas outlet pipe 3. A second abutting rod 17 is slidably disposed inside the second pipe 16, having a second abutting end 18 and a second sealing end 19. When the second abutting rod 17 slides within the second pipe 16, the second sealing end 19 can selectively abut against or separate from the inner wall of the second pipe 16. When the second sealing end 19 abuts against the inner wall of the second pipe 16, it can seal the second pipe 16, preventing gas leakage. The end of the second pipe 16 is designed as a plug-in end 20, which is used for sliding insertion into the first pipe 11. When the plug-in end 20 is inserted into the first pipe 11, the first abutting end 15 and the second abutting end 18 abut against each other, pushing the first sliding sleeve 14 and the second abutting rod 17 to move in opposite directions. This design allows the two connectors to automatically achieve sealing and on / off control during the connection process. In addition, the device includes a sliding member 21 slidably disposed on the outer wall of the first pipe 11. The side wall of the first pipe 11 has a through hole 22, and the side wall of the second pipe 16 has a locking groove 23. A movable abutment ball 24 is disposed within the through hole 22. By sliding the sliding member 21, the abutment ball 24 can be controlled to slide into the locking groove 23. When the abutment ball 24 slides into the locking groove 23, it can firmly fix the first pipe 11 and the second pipe 16 together, preventing them from loosening or separating during use. This design not only improves the reliability of the connection but also ensures the safety and stability of the device through mechanical locking.
[0038] Furthermore, it also includes a first elastic member 25 located inside the first pipe 11 with one end disposed on the first pipe 11 and the other end disposed on the first sliding sleeve 14. The first elastic member 25 is used to provide a force for the first sliding sleeve 14 to approach the second pipe 16.
[0039] It also includes a second elastic member 26 located inside the second pipe 16 with one end disposed on the second pipe 16 and the other end disposed on the second abutment rod 17. The second elastic member 26 is used to provide a force for the second abutment rod 17 to approach the first pipe 11.
[0040] It also includes a third elastic member 27 with one end disposed on the first pipe 11 and the other end disposed on the slider 21. The third elastic member 27 is used to provide a force for the slider 21 to approach the second pipe 16.
[0041] In this embodiment, a first elastic element 25 is provided between the first pipe 11 and the first sliding sleeve 14. One end of the elastic element 25 is fixed to the first pipe 11, and the other end is connected to the first sliding sleeve 14, located inside the first pipe 11. The function of the first elastic element 25 is to provide an elastic force to the first sliding sleeve 14 in the direction of the second pipe 16. When the second connector 4 is connected to the first connector 5, the first abutting end 15 and the second abutting end 18 abut against each other and push the first sliding sleeve 14 to move in opposite directions. After the connection is released, the first elastic element 25 can quickly reset the first sliding sleeve 14, ensuring that the device remains sealed in the non-connected state. A second elastic element 26 is provided between the second pipe 16 and the second abutting rod 17. One end of the elastic element 26 is fixed to the second pipe 16, and the other end is connected to the second abutting rod 17, located inside the second pipe 16. The function of the second elastic element 26 is to provide an elastic force to the second abutting rod 17 in the direction of the first pipe 11. When the second conduit 16 is inserted into the first conduit 11, the second sealing end 19 interacts with the inner wall of the first conduit 11. The second elastic element 26 ensures that the second abutment rod 17 remains sealed or open in the appropriate position, and can quickly reset after the connection is released. A third elastic element 27 is provided between the first conduit 11 and the slider 21, one end of which is fixed to the first conduit 11 and the other end is connected to the slider 21. The function of the third elastic element 27 is to provide an elastic force to the slider 21 in the direction of the second conduit 16. When the slider 21 slides to push the abutment ball 24 into the locking groove 23, the third elastic element 27 ensures that the slider 21 remains in the locked position, thereby firmly fixing the first conduit 11 and the second conduit 16. When disassembly is required, simply overcome the elastic force of the third elastic element 27, and the slider 21 can release the abutment ball 24, thereby unlocking the connection. By setting the first elastic element 25, the second elastic element 26 and the third elastic element 27, the device of this embodiment can realize the functions of automatic reset, reliable sealing and firm connection, which greatly improves the ease of operation and safety of use of the sulfuryl fluoride gas metering and control device.

[0043] Furthermore, a pressure gauge 29 is also installed on the second pipeline 16, which is used to detect the air pressure in the storage cavity 2.
[0044] In this embodiment, a control valve 28 and a pressure gauge 29 are installed on the second pipeline 16.
