DETAILED DESCRIPTION

[0022] The principles and features of the utility model are described below in combination with embodiments; the examples are used only for explaining the utility model; and are not used for limiting the scope of the utility model.

[0023] A sulfonyl fluoride fumigation pipe comprises a fumigation pipe body 1, a branch pipe body 5 and a spray head 6.

[0024] The fumigation pipe body 1 is formed with three chambers by a diaphragm, which are a medicine chamber 2, an air chamber 3 and a medium chamber 4. The medicine chamber 2 is used for transporting sulphuryl fluoride and is communicated with a medicine source. The air chamber 3 is used for transporting compressed air and is communicated with an air source. The medium chamber 4 is used for transporting temperature control medium, such as water with appropriate temperature. The branch pipe body 5 is formed with two chambers by a diaphragm, which are a medicine chamber 2 and an air chamber 3. The medicine chamber 2 of the branch pipe body 5 is communicated with the medicine chamber 2 of the fumigation pipe body 1. The air chamber 3 of the branch pipe body 5 is communicated with the air chamber 3 of the fumigation pipe body 1. The compressed air can spray sulphuryl fluoride more uniformly. The temperature control medium can keep sulphuryl fluoride at appropriate temperature during transportation in the fumigation pipe body 1. The number of the branch pipe bodies 5 is determined according to requirements. The branch pipe bodies 5 are one-to-one corresponding to the spray heads 6. The plurality of branch pipe bodies 5 are arranged in parallel. The branch pipe bodies 5 are arranged in an array along the length direction of the fumigation pipe body 1. The spray head 6 is provided with a spray port 7, a first inlet 8 and a second inlet 9. The spray head 6 is connected to the branch pipe body 5. The first inlet 8 is communicated with the air chamber 3 of the branch pipe body 5. The second inlet 9 is communicated with the medicine chamber 2 of the branch pipe body 5. In order to avoid mutual influence between compressed gas and sulphuryl fluoride, the first inlet 8 and the second inlet 9 are respectively connected with a one-way valve 10. The first inlet 8 is communicated with the air chamber 3 of the branch pipe body 5 through the one-way valve 10. The second inlet 9 is communicated with the medicine chamber 2 of the branch pipe body 5 through the one-way valve 10.

[0025] Specifically, the nozzle 6 is provided with a first flow channel 11, a second flow channel 12 and a third flow channel 13, wherein one end of the first flow channel 11 communicates with the first inlet 8, one end of the second flow channel 12 communicates with the second inlet 9, and one end of the third flow channel 13 communicates with the nozzle 7, and the other end of the first flow channel 11, the other end of the second flow channel 12 and the other end of the third flow channel 13 communicate with each other. Sulfuryl fluoride enters the third flow channel 13 through the second flow channel 12, and compressed gas enters the third flow channel 13 through the first flow channel 11, and is finally sprayed out of the nozzle 7. The compressed gas can increase the spraying pressure of the sulfuryl fluoride, so that it is sprayed more uniformly. The nozzle 6 is also provided with a fourth flow channel 14, and the fourth flow channel 14 is slidably connected with a plug 15, the fourth flow channel 14 and the first flow channel 11 cross longitudinally and transversely, the plug 15 is provided with a through hole, and when the through hole is axially aligned with the first flow channel 11, compressed air can enter the third flow channel 13. One end of the fourth flow channel 14 communicates with the second flow channel 12 through an auxiliary flow channel 18, so that the pressure above the plug 15 is consistent with the pressure of the second flow channel 12. The top end of the fourth flow channel 14 is provided with a limiting ring, the plug 15 can abut against the limiting ring by sliding upward, so as to form an upper limit for the plug 15, and the lower part of the plug 15 is supported by a spring 16, the other end of the spring 16 abuts against an adjusting block 17, and the adjusting block 17 is screwed to the nozzle 6. When the pressure of the sulfuryl fluoride sprayed into the second flow channel 12 is greater than the pressure of the compressed gas sprayed into the first flow channel 11, it proves that the sulfuryl fluoride can complete uniform spraying without the assistance of compressed gas, at this time, the plug 15 can be moved downward to close the first flow channel 11, and the compressed gas will not flow into the third flow channel 13.

[0026] The above merely describes the preferred embodiments of the present application; it is not intended to limit the present application; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
