[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a stainless steel gas path structure dedicated to a high-frequency infrared carbon-sulfur analyzer provided by the utility model; Figure 2 for Figure 1 A structural cross-sectional view of the protection tube shown; Figure 3 for Figure 2 A schematic diagram of the structure at A in the middle. The stainless steel gas path structure dedicated to the high-frequency infrared carbon-sulfur analyzer includes a protective tube 2 sleeved on a stainless steel gas pipe 1, the protective tube 2 is respectively connected with a first connecting ring 3 and a second connecting ring 5, and the first connecting ring 3 and the second connecting ring 5 are both provided with an explosion-proof mechanism 4 inside, which is used to prevent the fragments of the stainless steel gas pipe 1 from splashing.

[0020] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the explosion-proof mechanism 4 includes a positioning block 41 connected to the first connecting ring 3 and the second connecting ring 5, and four positioning blocks 41 are symmetrically arranged around the first connecting ring 3 and the second connecting ring 5. Positioning grooves are opened inside the positioning blocks 41, and positioning rods 44 are inserted into the positioning grooves.

[0021] By arranging four positioning blocks 41 around the first connecting ring 3 and the second connecting ring 5, and opening positioning grooves inside the positioning blocks 41, it is convenient for the positioning rod 44 to slide inside the positioning grooves, thereby ensuring that the positioning rod 44 has a certain buffer space, thereby preventing the protective tube 2 from being directly broken by the impact force generated when the protective tube 2 is deformed due to the large impact force inside the protective tube 2.

[0022] refer to Figure 1 , Figure 2 and Figure 3 As shown, a buffer cotton block 43 is sleeved on the positioning rod 44, and positioning bolts 42 are sleeved on both ends of the positioning rod 44. The top of the positioning bolt 42 is provided with anti-skid grooves, and the bottom of the positioning block 41 is provided with convex grooves used in conjunction with the anti-skid grooves.

[0023] By providing anti-slip grooves and convex grooves on the positioning bolt 42 and the positioning block 41 respectively, the friction between the positioning bolt 42 and the positioning block 41 can be improved.

[0024] It should be noted that: the protective tube 2 is slidably mounted on the stainless steel air pipe 1, the first connecting ring 3 and the second connecting ring 5 are cast as an integral part with the protective tube 2, the positioning block 41 is welded and fixed to the first connecting ring 3 and the second connecting ring 5 respectively, the positioning rod 44 is slidably inserted into the interior of the positioning block 41, the positioning rod 44 is threadedly connected to the positioning bolt 42, and the positioning rod 44 is fixed to the interior of the positioning block 41 by the positioning bolt 42.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, grooves 6 are provided around the protective tube 2 , heat dissipation fins 7 are arranged inside the grooves 6 , and a collecting groove 8 is provided at the bottom of the grooves 6 .

[0026] refer to Figure 1 , Figure 2 and Figure 3 As shown, the top and bottom of the protection tube 2 are both connected with connection blocks 9 , the connection blocks 9 are sleeved on the stainless steel air pipe 1 , and a sealing ring 10 is arranged inside the connection blocks 9 .

[0027] It should be noted that the heat dissipating fins 7 and the protective tube 2 are cast as one piece, the collecting tank 8 is arranged at the bottom of the heat dissipating fins 7 , the inside of the connecting block 9 is threadedly connected to the protective tube 2 , and the sealing ring 10 is inserted into the inside of the connecting block 9 .

[0028] The working principle of a stainless steel gas path structure dedicated to a high-frequency infrared carbon and sulfur analyzer provided by the utility model is as follows:

[0029] When in use, the protective tube 2 with the first connecting ring 3 and the second connecting ring 5 is sleeved on the stainless steel air pipe 1, and then the connecting block 9 is rotated to threadably fix the connecting block 9 and the protective tube 2, and the positioning rod 44 is inserted into the positioning groove of the positioning block 41, and then the buffer cotton block 43 is sleeved on the positioning rod 44, and one end of the positioning rod 44 is inserted into the positioning block 41 on the second connecting ring 5, and finally the position of the positioning rod 44 is adjusted according to actual needs, and then the positioning bolt 42 is rotated to fix the positioning rod 44 inside the positioning block 41. When the stainless steel air pipe 1 bursts due to pipeline blockage, the protective tube 2 can initially prevent the fragments of the bursting of the stainless steel air pipe 1 from splashing, and at the same time, the protective tube 2 will be deformed due to the explosion of the stainless steel air pipe 1. When the outer side of the protective tube 2 is deformed, it will collide with the positioning rod 44. The positioning groove inside the positioning block 41 leaves a certain buffer space to avoid the impact force generated when the protective tube 2 is deformed due to the large impact force inside the protective tube 2, which directly breaks the positioning rod 44. By arranging the heat dissipation fins 7 inside the grooves 6 on the protective tube 2, it is helpful to increase the contact area between the protective tube 2 and the air, and improve the heat dissipation box of the protective tube 2. When there is a temperature difference between the internal temperature of the protective tube 2 and the external temperature, water will condense on the surface of the heat dissipation fins 7 and drip into the inside of the collecting tank 8, which is helpful to reduce the generation of static electricity in the protective tube 2 and further improve the protection.
